Overclocking And Cooling Apple's MDD G4's 29
Currawong writes "At AppleTalk Australia, one of our members, unable to upgrade his production mirrored-drive-door G4 to a G5 due to software & hardware incompatibility, has instead has both over-clocked and made significant cooling modifications to his machine. He replaced most of the fans, including adding 4 ultra-quiet Verax fans, so the machine would run quieter, as well as cooler, in his studio. For those interested in how he over-clocked his machine, we've also posted his guide on how to do it."

Why settle for 25MHz when you can blaze along at 33MHz?

That's still a 33% increase though, which is a fair bit.
If you can reliably overclock a (say) 2.5GHz PIV to
3.3GHz - the same 33%, then I'd be impressed with that as well.

That's still a 1000% increase though, which is lotsa fair bits.
btw, anyone know where to get a reliable 40MB hd and OS 7.5? I need the System Enablers too. (duh, I gnow, ebay. its a joke, like the C64 loading from tape screen from GTA:VC. If you don't get it, you don't get it.)

To me, the real value in this article is not his personal account of squeezing that relatively pitiful extra performance from the thing, but the chart detailing how to nearly double the processor speed. Of course that would be ridiculously impossible to achieve, but the point is that it makes it clear enough how to be more adventurous than this guy.

The first line even says that this is a step by step guide to overclocking - choose your own speed.
Also the front page of the author's site shows he had that dualie up to 1.67MHz! Check it out for yourself www.bitsandpieces.info

But seriously, there is no damn way I'd overclock my dualie 1GHz MDD G4. With 4 internal hard drives and the Apple swapped-out reduced noise power supply, it's already blazing hot. If I close the door to my office, and I'm doing something CPU intensive like video compression, the room temp will quickly rise to about 90 degrees, despite my central air conditioning. But then, I have a really small office.

Given that so many factors contribute to computer performance (CPU architecture, number of caches, size of caches, bus speed, memory size, disk performance, CPU frequency), often in nontrivial ways, increasing the clock speed by such a small amount is unlikely to offer any significant increase in performance.
