Overclocking PPCs by tbo · 1999-06-08 01:24 · Score: 1

Anyone know how well PPCs overclock (specifically, the G3 and the 604)? There's not that much out there about overclocking PPC chips.

I hear Motorola makes quad-G3 motherboards (although I haven't been able to find a price or source anywhere). If they're not too expensive, I might pick one up and try overclocking it... Imagine four G3s at 600 MHz each...

Re:Overclocking PPCs by Anonymous Coward · 1999-06-08 02:29 · Score: 0

G3s overclock very well. Just about every one out there can be bumped up one level (e.g., 233->266) without even requiring a fan. Dunk it in refrigerated mineral oil and who knows how far you can go ;-> A separate question is the difficulty of setting the clock. Sometimes there is soldering required, sometimes it's just changing some jumper settings. I think some of the upgrade card manufacturers even have 'dial-a-speed' settings on their cards. The 604e doesn't overclock so easily, since they run 16 watts versus the 4-7 for the G3 (the Mach 5 604ev is lower power, so maybe it overclocks better). Check "Accelerate Your Mac" for more info:

http://www.xlr8yourmac.com/G3-ZONE/clock.html

Having said all that:

1) I don't think the quad-motherboards are cheap (too few produced).
2) A lot of the oomph in the G3 is due to the backside cache, which I don't think you can use in a multiprocessor setup. As a result, I'm not sure a quad-G3 would be much faster than a quad-604e (and possibly slower for FPU-intensive stuff).

You might be better off looking for one of Daystar's old multiprocessor Mac clones, or the multiprocessor cards they made for the PowerMac 9500 series. Guess you'd have to check if LinuxPPC would support the configuration...

Nonsense.

What ever happened to trying to do something to see if it can be done? I tend to view overclocking like hot-rodding a car. My P2/300 (On a Deschute core, no less) has been up and happy for the last week as a 3x112. Do I notice a difference? Yeah, I might be getting another couple FPS in Quake, but that's not the point. Is it less reliable? Shrug. Maybe. Would I overclock a server? Of course not. Heck, with cheaper chips (Cyrix, etc), an arguement could be made for _underclocking_ them to keep the heat down. But that's not the point.

As for the "If you want a fast machine, buy one" comment, I'd be more than happy to if you'll send me the extra couple hundred bucks for that P3/550 instead of the 450, but when you're talking about parts that are identical besides the rating they received from a factory, I'll take my chances on the 450 any day, and take the extra $200 for more RAM.

"Geez, they buy PIII and already think about overclocking it.."

Yep. And if I bought a new Porsche 911, I'd be putting a bigger exhaust, bigger fuel injectors, and turning up the boost within a few days, too.

The more I think about it, the more I see computers and cars the same way. Yeah, I always want a newer, faster one, but I'll still tweak what I've got 'till it complains too bitterly. I can't afford a brand-new 3000GT-VR4, but my 9 year old car will still whip it in the race of your choice. I can't afford a P3/550, either, but my 3x112 P2 is a heckuva lot faster than a 4.5x66 anyways.

As long as my P2/336 keeps running, hey, I got a free 12Mhz of bus speed. (Actually, since it's an older core P2, I've got a free 47Mhz.)

My computer will be "fast enough" right about the same time my car is. Those 3 or 4 minutes spent mp3-encoding or calculating or rendering continue to be unbearable.

One thing Intel likes to do, is bulk. It's cheaper to manufacture 300 Pentium 266 chips, then it is to buy 150 266's, and 150 233's. So Intel labels half of them 233, and sells them as 233. They have been tested to run at 266, and can run even faster if cooled properly. If you kick up a chip 30 mHZ, you're not necessarily going to ruin it, and you'll gain significant performance.

Actually, this isn't entirely true. Generally speaking, there are no intentional differences in differet speed parts, it's simply a matter of how high a frequency they test good at. Note that this doesn't hold true 100% though... for instance, PIIs at 333 and below are designed for a FSB of 66MHz, and the 300s and below use a different technology than the 333s and above. So you'll have very different luck trying to overclock a 300, a 333, or a 400/450. Also note that mobo/chipset can make a difference... if either of them present a large capacitance then you'll have more difficulty attaining higher speeds.
