SMP Linux on the Cheap
d^2b writes "There is an article using dual Celerons under Linux on cpureview.com.

plug two socket 370 Celerons into it directly.
The good news is that that author gets 183%
speedup over a single processor compiling the kernel. "
That is true, but for an upgrade you might need to add in a couple more factors (I would have had I taken the dual-Celeron route)
:)
ATX case: $90
64M PC100 RAM: $40
The dual Celeron's still faster though
Monopolistic behavior? No, of course not. Monopolistic behavior would be trying to run anyone else that produces SMP-capable processors and chipsets out of the business. Celerons were never intended for SMP in the first place, any more than my cel300a was intended to run at 464.
Your friends are on crack...
300a celerons oc'd to 450 on a Tyan Tiger 100, running RH 6.0.
I had to get all new parts, so it came to around $1600 or so: 2 300a celerons, fans, 2 MSI converters, 128 mg ram, 17 gig IDE, ultra tnt2, floppy, cdrom, 17" monitor, soundcard, ethernet card.
I did an ftp installation of RH from ftp.cdrom.com; I did it from my school so it only took about forty minutes. The only problem I had installing linux was getting my TNT2 to work properly with X. Had to lynx newer drivers from nVidia. I ran the install script, reran setup and it works perfectly now.
I had one of my more knowledgable linux buddies help recompile my kernel for SMP. Turned off the computer, switched one of the jumpers on the MSI board (WATCH OUT! they are very easy to drop and lose!!!) to set the bus speed to 100 mhz and I have 450 mhz celerons.
My computer whoops ass in seti and I can run two copies of bladeenc at once with good performance. One other nice thing about dual cpu's- if Netscape or some other app takes a dumb, it has less of a chance of bogging down or crashing your system, becuase it can only take over one processor.
I don't know where you got your numbers, but I have to disagree with some of your assumptions:
First on prices : (best Canadian prices I found )
c400 : 149 ( x2 $298)
K6-3 450 : $245
Socket 7 board : 119
Dual Slot 1 board : 400
And I found that a K6 chip was 40-50% faster for kernel compiles as compared to a similarly clocked Intel chip.
True, a dual celeron would be faster than a single K6 chip, but I'm saying that a Dual K6 would be a fantastic ( and not too expensive ) machine! The celeron system isn't *that* cheap!
The fact that no one understands you doesn't mean you're an artist.
I did it! My lone Celeron 300A is now 504MHz. Doesn't seem any faster, but RC5 might be able to crunch a few more keys... I had to change the core voltage to 2.4volts and set the BIOS to ignore the "error" of this higher voltage. The CPU did not like 2.0volts and scrambled the eggs on the hard drive with 2.2volts while compiling the kernel. The CPU does not seem to put out any heat, so 504/113MHz it is!
I bought one of these on the 1st, it's a great board. I put it in my Multi-OS machine, since I use my Linux box for work. So far I've been running Solaris 7 and BeOS 4.5 on it, and it ROCKS!!!
I've got the Abit BP6 with 2 400Mhz Celerons, 2 128Mb DIMMS (still can't believe how cheap those were), a Matrox Millenium II, SoundBlaster AWE 64, and am using EIDE drives. I'd like to put U2W-SCSI on the system, but didn't feel I could afford it at the moment, besides I don't really need it.
I'm SERIOUSLY thinking of replacing the PII/333 in my Linux box with a simular setup. But want to find time to take Linux for a spin on this box first, just need to find time to reload the Linux HD I've got for it with something more modern than what's on it.

You're a fugitive from Segfault, aren't you?
A couple of months ago, the crazies at HardOCP managed to get a Celeron 300a to run "stable" at 600Mhz!!
Of course, their cooling rig was a work of art...water-cooled TECs...
Never let your fears overcome your dreams.
And not enough PCI
Fog
In reality, clocking Celeron 300As *is* that easy. Mine doesn't even need more cooling than the standard heatsink and fan (retail CPU), and it's totally stable with 2.1V core.
Remember, the Celerons use the same core as the PII-350/400/450, with the addition of on-board cache (cooled by the same HS/fan rather than sitting there in a stuffy cartridge).
This box has been running at 450 or 464 every day doing RC5. Overclocking isn't something for everyone, I make sure people know the risks assocoated with it before I'll help them build/clock their Celerons. But in reality, the risks are very low. If it dies, just go back to bios and knock it down a bit. Even when I couldn't get into bios (attempt at 600+mhz), it was just a single jumper on the board to reset it back to defaults.
It's simple; know what you're doing, check the CPU temperature and test your chosen speed/voltage thoroughly before settling on it.

Intel didn't officially go as far as 42Mhz with
the PCI bus specs, so quite some manufacturers
have created hardware that dislike PCI busses
running on 37,5 or 42 Mhz (mobo speed 75/83).
Common examples are the Voodoo II cards(in particular the ones from Creative), most S3
cards and (all?) Maxtor HD's.. On the latter, setting the busspeed higher causes busmastering transfers to fail and in the worse case you'll fry your interface.(afaik quite some IBM hd's also dislike it)
Some mobo's have an extra jumper to
set the PCI/AGP speed at a fixed rated (33Mhz).
I'm running OCed Celerons since a year now
(one 300 at 450 and one 300a at 450 at regular
voltages) and it runs stable at 100mhz (= 33mhz PCI bus), though the xxxa series do require extra cooling because the cache chips tends to heat up a lot, when ocing.
I've been building/selling/tweaking computers for over 15 years. Most of the RETAIL versions of Intel CPUs overclock well and have great track records of longevity in my experience. The RETAIL version is worth spending extra money for if you plan on overclocking. We have many clients running OC'ed Intel PI/II CPUs with absolutely no complaints or failures. We haven't RMA'ed an Intel CPU in over a year.
The only processor I consistently have trouble with is AMD. Many of our economy line computers based on AMD processors have failure rates like 1 out of 5. We have in a month replaced 4 AMD K6-2 266 CPUs ranging from 3-7 months old. They just die, no boot, a variety system configurations, and locations. Last week a K6-2 350 in a hardly ever used Win95/WinFax machine.
I don't like SlotKet idea. It reminds of those SIMM savers that broke sockets and got in the way of things. Honestly, I haven't tried them myself but its too much of a kludge.
I have ordered a ABIT BP6 with retial 366's, PC-133 128MB(Enhanced). Can't wait to play with it.

Anyone here ever stress-test IDE?
Using a Diamond Fireport 40 (single channel), two ultra-wide 9.1 gig IBM Ultrastars and one ultra-narrow 4.5 gig of the same family (all 7200 rpm), a reasonably quick Conner tape drive, 32x Plextor CD-ROM, and an 8x Plextor burner (all at 10MHz due to cabling issues), I have done the following, concurrently:
Run a tar backup of part of an UW drive, while cdparanoia rips an audio disc in the CD-ROM and bonnie is repeatedly stomping out a 700meg file on the narrow drive, and cdrecord burns through a CD-R at 8x from the other UW drive.
I let it sit for a bit, and noticed that cdrecord was showing no signs of its buffer beginning to empty, so I fired off updatedb and a few fscks on unmounted partitions.
After a few more minutes of horrid thrashing sounds as the hardware struggled to keep up, cdrecord ejected a perfect CD-R.
Can IDE do this, let alone on a P-133 such as that which I was using at the time? I suspect not, but I welcome any reports to the contrary.
It might also be worth mentioning that Netscape (the most cpu-intensive application I regularly use) was very responsive during all of this, probably due to the near-zero CPU time required to tend to a decent SCSI adapter.
(and for those of you who are thinking of flaming me for using a battery which is highly unlikely to occur in the real world, consider this: he who wants to have a computer which is capable of doing only one difficult task at a time is probably better off with the simplicity of ms-dos. it's faster, too - just imagine wordperfect 4.2 on a PIII/500!)

I am very happy with my dual celeron 300a's that I have aquired. So far I am able to compile a 2.2.10 kernel in less than 90 sec. with a lot of features added. Modules take another 50 sec. since I also like to try to keep my kernel size down ~ 430K.

I build my BP6 and it was like a wobbly goblin. Nonreproducable crashes everywhere. I tracked it down to my SOUND card. I replaced it and now everything's fine. I'm using nice ECC PC100 RAM and was quite puzzled, as you are now.
Go to www.kikumaru.com and check out the dual Celeron discussion board. You might get some better help there.
I had my system (dual 300a socket 370, MSI converter, Epox KP-BS) go flukey after a while. I had the computer in pieces for a month. I finally decided to up the voltage to 2.2 (by covering some pins) and it worked. But then the monitor wouldn't go on. From the beeps on the motherboard it turns out that it was a graphics card prob (I have an agp tnt). Epox site said to make sure the card was plugged correctly because the agp slot was very sensitive. I shoved that card in real tight and everything works fine now.

"a battery which is highly unlikely to occur in the real world" ?
That happens to be my real world (tarring, while burning, while ripping, while compiling, while serving for friends, while working on GIMPS, while catching up with mail and news, while trying to break the DB2 beta). I have a lot to do and I like to get it done quickly. I can only work on one thing at a time, while my boxen can do many things at the same time. I see that SCSI lets me do this well, even with slow SCSI, while IDE barely limps along, even with fast IDE. The choice is obvious, even if you have to live on Ramen noodles for a while.
Hey,
I wholeheartedly agree that a dual Celeron setup is a steal! I've had one going for about a week, sporting 2 Celeron 366s running at 550 Mhz (at default voltage, these are both week 15 SL35S chips, must've been a good batch) and boy it is fast (and rock stable, so far)!
However, instead of the BP6 I opted for the Epox KP6-BS with MSI 6905 rev. 1.1 slotkets. I just wouldn't feel comfortable being stuck on socket 370. With this setup I can just swap in 1 or 2 PIII-550s by the time they become cheap and get some of that SSE-loving. On the other hand, there are rumours of s370 versions of PIII coming, who knows Intel's real roadmap anyway? Everyone take their chances...

Michiel

The death of one man is a tragedy; the death of a million is a statistic --Joseph Stalin
The idea of using Celerons only works if you can overclock them. It may go well for hacks and tinkers, but for the heavy video and I/O, a 66Mhz bus frequency is unacceptable.
In the article, the guy ran one of the chips at 2.1 volts... I wonder how long it stayed stable at that speed/voltage. I have a C300A that runs perfectly stable at 450 MHz 1.9v, but crashes regularly if I use default 2.0 voltage. These PPGA Celerons don't dissipate heat as well as their Slot-1 brothers can.
I would expect memory bandwidth to be an issue with SMP Celeron systems, especially if you're not overclocking. The last part of the article touched on this, but I think a lot of people still don't get it...
The Celerons only have 128k cache, compared to 512k on the P2. The Celeron cache runs at twice the speed of the P2 cache, often resulting in better single-processor performance, but because the Celeron cache is smaller it has to go to RAM more often. This means that the Celerons consume more memory bandwith than the P2s.
Combine this with the fact that an un-OCed Celeron runs with only a 66 MHz bus, compared with 100 MHz for a P2. Even though the Celeron needs more memory bandwidth than a P2, it gets less.
Now stick two of these bandwidth-hungry chips on the same board accessing the same 66 MHz RAM...
I suspect it would not be worth it unless you used 300As at 450+ (100+ MHz FSB).
Does anyone have performance numbers for un-overclocked Celeron SMP?
Its not a SMP with my P2B motherboard, but I have tried my Celeron at 503MHz with the bus speed at 113MHz and it will run for about ten minutes before the kernel oops with a memory page error. Its been running at 463/103MHz since October without a glitch. Has anyone had success with a 113MHz bus speed?
Actually, it's 61.5%...
After reading this article, I'm now very interested in building a cheap SMP system. However, I want to get the most bang for the buck.
In your opinion, what is the best celeron to buy for the money (esp. considering the overclockability of the chips). I saw pricewatch advertising 300a PPGA's for $51 and 400PPGA for $76.
Also, what is the best mb to buy for the money? Is there a good one that has sound and video integrated and works well with linux?
Anyway, I'm trying to keep the price close $400 (not including shipping) so I can do it before summer is over.
Here is my tenative(sp?) plan:
2 - 128meg PC100 Dimms - $140 ($70 a piece)
2 - 300a Cels - $102 ($51 a piece)???
1 - m/b ?????
1 - 8 gig drive free (already have)
1 - 10/100 d-link nic $30.00
1 - cdrom ~$40.00
Anyway, any advice on how to do it/what to buy would be appreciated.
Thanks,
Waxman
what a complete waste of money. you buy two fast processors and then stick IDE drives in the system. SORRY CANNOT COMPUTE REQUEST.
If you'd bother to read the cpu review which this thread is after all about, you would know that ATA-66 drives are comparable in speed to SCSI 2UW. Note: I say "comparable" not as fast as. But for the price, you can't beat it.

But there are places that will sell you a tested overclocked celeron system.
I cam across this one the other day:

Just installed my new P6 w/ dual PPGA 370 CPUs. Set speed from 300(66) to 450(100) in the BIOS, and booted into Windows, and got the blue screen of death. So, rebooted, and then set the CPU voltage from 2.00 to 2.05 (NOT 2.5!!!), and everything works like a charm. Norton SI went from 95 to 146 (just by overclocking from 300 to 450) and BeOS full-screen chart demo easily get 600 FPS w/ 2 threads and the default star setting. Will be testing Linux performance soon. The BP6 is a nice motherboard!
The celerons are underclocked to begin with. The core is the same as that of the PIIs running at 100 FSB.. The only issue should be the cache. I run dual 300As at 450 with no issues. The CPUs don't even really heat up that much.
From what i've seen, the biggest issue when doing SMP OC'ed celerons is the MB and the slockets.
Intel CPUs are tanks.. I've worked at a computer store for over two years.. Since the day I've started we've had a total of 3 intel CPUs ever fail (including DOA).. I've seen some techs/customers do some pretty evil things and the CPU just gets up and runs again.. In one case a computer was caught in a lightning storm, and the line surged. Took everything out but the CPU.
Besides, even if you did manage to break a celeron, they're cheap as hell. My MB cost more than both CPUs and the adapters.
I think everyone should at least look into Dual Celerons for their next upgrade. Highest bang-for-your-buck ratio i've ever seen.
A few months ago (I really should have waited) I bought a tyan tiger MB, the cheapest dual bx I could find. I got some modified msi converter boards, and a couple 300a's. The total price was about $80 more than it would be now with that dual 370 board. They both overclock to 450 just fine. I keep a big fan next to it, so they only get up to about 34 degrees on a really hot day. It's crashed a few times in a virtual terminal, but it even does that in cold weather and not overclocked. never crashes in X though... odd.
My Utra 10 does 8.7mkeys/ec, so neener :)

... (but who'd want to, Pentiums have no on-die cache, would have to share L2 between cpus and that would SUCK! )
don't be so hasty! in fact, as with almost all computing solutions, it depends. Some people have reported speedups of ~105%(!) with two MMX Pentiums. This is the case, when both CPUs work on the same set of data and one CPU already prefetched the data into the shared L2 cache. This kind of effect is NOT possible with seperated caches.
But you're right saying that most of the time a shared L2 cache is worse (esp. with >2 CPUs).
Btw. why do you think dual Alpha boards have a unified L3 cache?
Thats the thing then, IMO. I have seen many MB at work, but Asus are the best so far. Can't wait to get one. Hell, can't wait to try this setup, and give my AMD K6-2 366 to a friend of mine still running a P166mmx. But remeber, Ram is key. Get at least 128megs if you want a realy kickass machien, and 256 later on, when you've saved up another $100. Also, Word to everyone, for real performace, get CAS2 rather than standard (CAS3) 100MHZ sdram. It has a lower latency, and is faster. It is also about $15 more than CAS3 stuff, but worth every penny.

A brief log of my experience can be found at my website. Boring ... it just worked.

First, ram is truely the key to a fast system. Yes, having a badass, dual CPU Celeron system OC'd to 464 is awsome, but if you are going to spend the $240 or so, bare minimum, on this, spend another $100, and get 128M of ram. And not just any ram. Be sure that when you are buying it, it is CAS2, rather than the standard CAS3. Of corse make sure it's PC100 as well. Don't go for PC133 just yet, it is far to expensive, and no MB or CPUs support it yet.
Second thing, send me lots of money for my advice! I want to get one of these too. %^> Oh well, guess thats not going to happen. Looks like time to save every dime I get again.
I think this is an excellent idea and think more
people should take advantage of this feature intel
poorly removed. I have a dual celeron 300 mhz
system using a tekram dual slot 1 motherboard
and i am using two msi slocket adapters. I
overclocked both 300 mhz chips to 503 mhz using
fans (over a GHZ!) I did use a whole lot of fans,
2 x 3 fan units for the cpus and 3 case fans. The
case runs at 90 deg avg. This system has been
running this for a month and a 1/2 totally stable
running 2.2.6 It is the fastest thing I have ever
seen. I can compile a kernel in 3 minutes flat.

I'm running at a cool 540 Mhz on each processor. One processor would not run at 550, the other did. I had to pipe it down to 98 mhz on the FSB and up the voltage on the one processor to 2.2v, but it WORKS now!!!
Has anyone put together a Linux SMP system based on the dual-socket 370 motherboard from Abit? I saw an article about it a few weeks ago but nothing about pricing, availability, or technical details of the dual-S370's SMP capabilities/limitations...
Geeky modern art T-shirts
I put together a Dual Celeron machine (Asus P2B mobo and 2 PPGA Celerons with Slot-1 converter boards) and it does indeed fly. You can't beat the bang for the buck on this one.
and oh yeah, first p0st!@!#@@!
The idea of using Celerons only works if you can overclock them. It may go well for hacks and tinkers, but for the heavy video and I/O, a 66Mhz bus frequency is unacceptable. The chances of overclocking single celerons to a 100Mhz bus is 75%. For both processors in a dual processor system, the success drops to 56%. Also since people are much less willing to report failure publicly, the percentages may even be lower in real life. You won't see anyone post a failed overclock on slashdot.
I will be trying it out tommorow hopefully. I have already received my Abit bp6 and I'm just waiting for my celerons to be delivered. Their sitting in a ups station 20 mins from my house, but yet I can't get them till monday *sigh*
I read somewhere that Intel was going to start producing the pentium !!! in the ppga style.
I have 2 366 MHz Celerons on my BP6. Mandrake 6.0 and BeOS 4.5 run very nicely, thank you.
Abit is a fine motherboard company, and benchmarks have shown that dual celerons run just as fast, if not faster than pentium IIs. This means Intel will try to take out the celeron's ability to do smp. (forcing us to go with the more expensive pentium IIs/IIIs) Wouldn't that render the BP6 useless in the (near) future?
Mine is on order and due to arrive next week. Price tag on my custom built system from KC Computers? $2500~. Here's what I got:
As you can imagine, I'm chomping at the bit in anticipation. And with ADSL services at $49.95...

What happens when a CPU gets too hot is that the system locks up. You wont get any burning plastic from an overclocked CPU unless you try something really stupid. I've got a standard Celeron 300A, no extra fans, no extra voltage, just bang it in and run it at 450MHz. I've had it for nearly one year now ane not one problem.
You're just spreading the Intel FUD.
(Besides, the Celeron beats the PII in some tests when you run them on the same clock frequency, due to the fact that it's cache runs at processor speed)

I've heard positive reports from people who have, and my dual-370 stuff is on the way.
Yeah.,. that seems imposible, but i have three friends that say.. with a Legend QDI Motherboard, a Dual K6-2 configuration is possible.. u know anything about this?
Just for grins would it be possible to overclock also ? You can get 366's guarenteed to run at 550 from places like www.atacom.com.
I've been using a dual-celeron system for ~ 1 month now ( 366 on 83MHz bus - 458MHz ) and have had NO trouble at all ... standard fans / heat sinks, and they're cooler than standard PII's ... and as long as you've got enough ram this is the fastest machine I've ever had the pleasure to use. Now if only I could find an OpenPIC mobo and run dual K6-3's !
The fact that no one understands you doesn't mean you're an artist.
I built this system with an MTech M668DS LX chipset dual slot 1 motherboard, matrox G200, 128 megs of 6ns ECC SDRAM.
I'm using two celeron 366's on pre-modified MSI MS-6905's. I am not overclocking.
Doesn't work worth a damn. My uptimes range from 3 hours to 2 days. It's like using Windows or something.
If it were a memory problem, I'd see ECC complaints all over my logs. My cpu's have huge heatsinks and lmsensors report that they rarely get over 44c, so it can't be heat.
It usually crashes when the system is doing nothing more complex than animating the "Ifs" xscreensaver module. It never has crashed during a kernel compile, though i recompile every week or so, and use make -j4.
At this point, all I can figure is that the slotkets are defective. I don't expect to get a refund from the place i bought them from. I've ordered (far more expensive) PowerLeap slotkets on the off chance they might work better.
If that doesn't work out, I'm probably tracking down a pair of PII-333's. Which would suck, because this system performs very well when it's not locked up.
This is just like television, only you can see much further.
Here's a story at Ars Technica comparing dual Celerons to dual PIII's, both oc'ed. Results were suprising, to say the least.
(I don't believe this is a fluke, either. My machine is basically the nerd box, but at 464, and it is thus far is proving to faster than I expected, close to PIII 500 speed (without SSE, of course).)
If enough (who knows how many that would be?) people state they want the feature left in, Intel might cave to public pressure. Remember the DIV bug? F00F bug? In both cases they gave in to public pressure.
--------- Webmaster, http://www.cpureview.com and
Yes it is. check out pricewatch.com, atacom.com.
on same site that this news thread is covering: cpureview.com, he has k63 linux compile time:23.5% faster than a celeron. Let's see your #'s showing 40-50% faster on linux compilation. note: his dual setup even only had 64mb of memory!:)
This sounds like a bad idea. Intel obviously dosen't want people to do smp with celerons, they want people to have to shell out cash for the p2/p3's. If alot of people sign the petition, intel will know how many people are using celerons for smp. Then they will figure out how much money they are losing and this will justify them taking smp out of the celerons.
i guess you could count me. just powered them on yesterday. i'm using sl36c maylasia parts and the globalwin fans. they seem to go 550 at 2.05V.
"guess" and "seem" are because i see occasional weird behavior, not outright crashes. kernels compiled -j 4 do work.
this is all on mandrake 6.0, which does seem to be an improvement over redhat 6.0.
i was fully prepared to go as low as 506 (92 FSB, still with 1/3 PCI divisor) but the board absolutely doesn't want to hear about that FSB frequency.
Did you get Linux to work with the HPT66 controller on the motherboard?
Maybe this petition should be forwared to microsoft (yes i know) because AFAIK win2000 will not be supporting dual celerons (and believe me build 2031 does not support dual celerons)
Surely if intel was to remove the smp capability of the celeron they would lose market share to another cpu company.
I'm running the abit BP6 and NOT overclocking my celerons. HEAVY I/O my ass. PC100 is only marginally faster than PC66 because both types of RAM have approximately the SAME latency. Only if you read huge continuous chunks of memory at the same time will you see a significant improvement on the 100Mhz bus.
You want heavy I/O? Get a fuckin' Alpha and shut up.
You want the coolest dual processor box around that: 1) - mere mortals can afford and 2) WILL embarass PII/PIII systems of the same clock speed? Get an Abit BP6. Overclock only if you like to tinker. You really don't need to.

Sick of hearing Fry's salesfucks like you talkin' out yer ass.

Maybe it doesn't matter. The people at Rise (http://www.risetec.com.tw) told me that their new cpu will be a Socket 370 400 MHz Celeron clone. It won't be overclockable but it will be able to run SMP. Should be out 3Q 99.
BTW, they test their cpus with Linux, Be and QNX.
I'm running a petition to ask Intel NOT to remove the SMP capability from Celerons... I can use more signatures :-)
4957 signatures to date.

It's a 183% utilization. The speed up is 77.4%.
He he he...
...unless you do something really stupid...
Let me quote myself:
;)
I still don't think this would be an issue with the Celeron, though.

CAS2 RAM is the only way to get a stable OC'd system. It can operate on elevated BUS speeds, and has a tendancy to dissipate heat more readily than your normal RAM. CAS2 RAM is also more expensive. Check out pricewatch.com. --Bryan
You can spend $90 on an atx case. Can also spend $25 on a generic atx(about 10 or so listed on pricewatch) or $40 for an inwin case(also on pricewatch). $30 for 64mb pc100.
Hi,
I have build a smp system based on an abit bp6, linux however fails to recognize the ata66 controller present on the board (with or without disks connected to it). The controller is produced by 'Highpoint'. Did anybody get this controller to work with linux ?

Would that be considered monopolistic behaviour? After all, people are buying more and more celerons because of it's ability to use SMP, yet being cheaper than P2s and XEONs. Yet Intel forcibly wants them to buy the more expensive chips if we wanto to do SMP.
Inquiring mind want to know.
Last weekend I took the plunge and
bought an Abit BP6 and two - week 14
Malay Celeron 366's. I have them
running rock steady at 450MHz under
Mandrake6 [1009.26 bogomips SMP] (and NT-4 and
win98se). I've had it compiling kernels and
plowing through setiathome for a few days
now and so far not one crash.
Now if there was just a way to watch
DVDs under Linux life would be perfect!

system desc:
Abit BP6= $145
2*366 Celerons @ $78 = $156
128MB PC-100 ECC Memory = $128
Quantum - FireBall CR (13GB 66MB/s) = $173
Toshiba DVD SD-M1212(OEM) = $98
InWin A500 Case = $58
Rest I already had laying around (Matrox G200
etc.)
I was just wondering how many people out there have had sucess o/c their celerons 366s to 550 ppga only. I ordered them with the abit bp6 and would love to have them run at 550.
Do you honestly think that this would have any effect on Intel? Why not just put together a petition asking them to give away free processors on request?
k63 450: $190 23.5% faster than single celeron mhz/mhz(300a@450/100) compiling linux.
c400x2: $150 77.4% faster than single celeron. 27.7% faster than a k63 450.
s7 mb: $55-90
lx dual mb: $35 + $20 for slot 1 converters
abit bp6: $130
without overclocking even:) If I were going to
do that I'd get two c366's for $120 & go for 550MHz(75.6% faster than a k63 450).
These may be results for just linux compilation but it's represents the speed gain for everything compiled or assembled using a makefile( -j #).
Just curious, now that Celerons have the locked multiplier, could I run a 4.5x and a 5.0x (300a and a 333a) in SMP? I currently have a dual 300a/504 system, but it has occurred to me that:
a) On old systems, the multipliers were set at one spot on the motherboard
b) The processors don't know what the multiplier settings of other processors are
c) They communicate to each other at the bus speed
This to me would mean it is entirely possible.
I know people who have gotten a PII and a Celeron to work. Anyone want to take a stab if you can have to different multipliers?
