A lot lower for alloys so it really depends on what it is. If we assume it's pure iron and a decades old drive then you are correct but small traces of other alloying elements have a dramatic effect (eg. for most stainless steel it's below room temperature in the extreme example).
There's a discussion at http://www.ocforums.com/archive/index.php/t-454159.html of a few different magnetic materials used in drives and Curie points with a few links to where they got the source data from.

I wrote an overclocking buyers guide and I have been updating it relatively frequently over the last few years. it hasn't been updated in a few months tho as my work has started taking up more of my time. but, it too could also be seen as a gaming guide http://www.ocforums.com/showthread.php?t=483065

Something with South bridge 750, so ether a 790GX or one of the newer 790FX/SB750 mobos, the earlier models had SB600, and don't overclock as well and lack a few features that SB750 added like Advanced Clock Control. I'm personally looking at this Asus http://www.newegg.com/Product/Product.aspx?Item=N82E16813131339 , though the DFI 790FX/SB750 also looks good. The Gigabyte DS4 seems to have mixed results though, while AMD used it for their demos to get the Phenom 2 to 6.2Ghz on LN2 others have had trouble with it in over volting stability, Which is kind of important since if I remember right AMD said that the Phenom 2 is rated safe to overvolt by them up to 1.55v. Most of the overclocking forums are already geared up in anticipation, if you plan on clocking it, take a look http://www.ocforums.com/showthread.php?t=591256 Here's to hoping I can afford to build out an all new box for Phenom 2 4-4.5Ghz on water, 8Gb of DDR2 1066 or better and an HD4870 1Gb, maybe one of those nice new XFX made black PCB ones, and see if I can get that up to 860Mhz Core/4.8Ghz ram on the water as well. Hello HD video editing, gaming and running 6 OSs in VMware at the same time without slowdowns.

Yes, it's DRM, but considering the fact that it lets you install your game anyway, as many times as you want, on whatever computer you want, I'm willing to accept it.

Yep... When ever you want.

The question is, who do you trust? Lately, big business is going down fast while "evil pirates" are getting more trustworthy. I have more trust for a 14 year old Russian kid than I do for Sony.

I don't pay money for Google. If I'm paying for a game it better not have any ads in it. It would be like paying to see Blade 3 or I, Robot or the new Casino Royale or paying for a copy of NFSU2. I'm not going to pay twice.

Yea - when I can get 750MB/s sustained throughput to / from hard drives, count me in. Until then, I'm saving my pennies for a rig like Nostromo5 over on Overclockers. Six SSDs (Gigabyte iRAM) running RAID 0, using a second computer (actually just a powered motherboard) to host and power them. That's three Gigabytes of data every four seconds, sustained. Best part - he did it almost a year ago - not sure what's come of it since then.

And will be obsolete in a year. Honestly, who spends thousands of dollars every year for the most advanced stuff?

to answer your question, the people at Overclockers Forums, Xtremesystems Forums, and any other person who tweaks their computer for fun. It's a cheaper hobby than boating, for example.

A quick google search appears to show modern PDAs competing nicely with a mid-80's Cray.

yes people still overclock. http://www.ocforums.com/

and yes you can get a lot more performance out of your processor by overclocking vs. buying the faster stock-rated chip. FSB is sort of the clock that everything in your system runs off of, so when you take an "old" Conroe chip that ran at 266mhz fsb and raise it up to 400mhz, you not only make that chip run faster, but you pretty much make everything run faster.

Over on Overclockers Forums we have a pretty good comunity of overclockers that use Linux/Unix/BSD/Alternative OS's, especially because we have a Folding@Home team (Team 32) that likes to run Ubuntu 64bit in a VM in Windows to use the SMP client to increase their PPD.

Comes with F@H preinstalled, however you have to change the username and team name to yours (he's with Extremeoverclocking), but it's for everybody. I Fold for Team 32 so just changed that. It comes with Samba so can control Folding utilities like EMIII with WinXP, Rdesktop, VNCviewer (no clue how to do these yet, but if need to I'll learn how).

Next going to use it on old PII 366 Mhz. I will probably just install that to old hard drive and start learning Linux. Next will dual boot main machine with one of the flavors of Ubuntu?

Only problem is I really don't understand Linux as I am wanting to update Firefox to 1.5.0.4 but no go so far. Can you update with LiveCD using only Ram (756mb)?

"I am new to liquid-cooling, and I have designed a system for use in a micro-ATX OpenBSD server, with the following layout: Fillport > Reservoir/Pump > Y Split (one to CPU and the other to chip-set) > Y Reconnect > Radiator/Fan > Back to the fillport. I don't like the idea of having the hot coolant coming from the CPU going directly to the chip-set, hence the Y split. Could this split cause any problems? Would there be a difference in pressure (considering the CPU is most likely a lot hotter) that could cause an issue? How would you handle liquid-cooling more than one component? What if I wanted to cool 3 components, such as in the case where I add a video card to this setup later on?"

Splitting the main(Y-split) to cool several devices is generally not recommend over cooling multiple components in serial.

Most people go: Pump->CPU->radiator->reservoir

some people go: Pump->CPU->Video GPU->radiator->reservoir

and very few people go: Pump->CPU->Video GPU->Chipset->radiator->reservoir

( or even Pump->CPU->Video GPU #1>-Video GPU #2->Chipset->Memory->radiator->reservoir)

As you add more and more stuff to the circuit, you'll also need a bigger pump, a bigger radiator, and you'll have to seal the connection points more carefully to gaurd against leaks resulting from higher pressure. It's the general consensus that splitting the coolant in a parallel fashion like you're describing is less effective than connecting the components in serial. The primary reason is that flowrate X volume is king in water cooling...with a Y-split you're cutting your CPU water cooling volume in half, and probably restricting flow even further with narrower tubing. Also, pressure drop in the system is a function of how much tubing you use. More tube, less pressure. People have tried this before...and their results weren't comparable with serial.

I'm assuming you want to water cool so you can overclock. If this is so, then you need to prioritize your CPU over everything else. If you don't plan on overclocking and just want the silence, then you're still better off using serial because it's cheaper and safer(less connection points means a lower leak probability).

Don't worry about warm water returning from the CPU and 'heating' the chipset. Fast flowrate and the high heat capacity of water keep this from being a problem. Generally the water temperature across the entire circuit is nearly homogenous(maybe 1-2 degrees difference).

2) Spend at least 2 hours reading the stickies etc. (or register and ask your own question, the folks there are very knowledgeable.)

Good luck with it!

Intro to A64 Architecture

Traditionally, a Northbridge existed between the memory bus and the CPU. The rate at which data is transferred between the memory and CPU is known as the front side bus. However, the Athlon64's memory controller is on-die, and as such, has no Northbridge, nor a front side bus. The Athlon64's have two independent buses; one between the memory and the on-die controller, and another bus that communicates with the other system devices- the HyperTransport bus. The CPU's clock speed is determined by the HTT speed multiplied by a clock multiplier, which is why it's often suggested to view the HTT as if it were the front side bus. However, this is about where the similarities between the two diverge. The HTT is, in fact, not a data path or bus, simply an internal time off of which the HyperTransport and CPU speeds are derived. The HyperTransport bus' effective speed is determined by an LDT(Lighting data transport) multiplier, multiplied by the HTT. Traditionally, the memory speed is derived off of the front side bus, and can be manipulated by FSB/memory ratios. In contrast, in the A64, memory speed is derived off of the CPU speed in CPU/memory ratios. This is why it's rather inaccurate to say that the memory is ever running "synchronously." The memory is always running asynchronously with respect to the CPU speed, off of which it's derived. How fast it's running with respect to the HTT does not matter at all. There is no latency hit in running the memory slower than the HTT. While the front side bus could've been traditionally double or quad-pumped, the HyperTransport's effective data rate can be anywhere from 1x to 5x it's speed on the CPU.

Follow discussion in forums about what Batch number OC well. Get some understanding of the Semiconductor industry by comparing Temp vs Geometry, etc.

If you build your own rig the best way to learn and have a good feel for it is by trying to OC. OC the Graphics card, OC the CPU. Fiddle with FSB vs Multiplier and benchmark the various settings.

It's a hobby.

It seems the writers of the article forgot about SNDS Sudden Northwood Death Syndrome which seemed to stem from overclocking with too high of voltages. I recall reading that the problem was electromigration.
