How Far Will A Peltier Device Really Take You?

[Jimbo]

Right now I have a Pentium III 650e (CB0) that is running stable at 936@ (144FSB).
ASUS P3V4X (Rev. 1) and Some Mushkin love that is supposed to be good for up to 160 FSB, a PC Power and Cooling 425 Watt power supply, all on Windows 2000. I need to see 1GHz on this beast before I die. J
When I make a run at the higher clock speeds (up to 150), I get the Windows cannot find a file to start up error message. I clock it back down and all is well. I have never had a corrupt registry or anything that made me reinstall the OS.
Will a Tom Leufkens Peltier Element (50 Watts) make any real difference on that extra 75MHz I need?
I already have the Alpha on the CPU and the heat sink/fan on the clock generator.
Is anyone running anything similar at over 1GHz?

Here is my experience with the Tom L. Pelteir: Overall good unit, but it won't get you much farther than the core is already capable of with decent air cooling due to the nature of the coppermine core. For example, it will allow me to take my 550E from 759 max with an alpha heatsink up to 786. It will let me take a subborn 700E and get it up to 784, whereas it won't reach higher than 721 without it.

But on some chips it does not seem to help at all, especially when they are at their limits already, such as yours may be.

A side note, whenever I get that error it is in fact due to my ram being set to cas 2 at a bus speed where it can really only handle cas 3. I would try setting it to cas 3 and see what happens. The performace difference is so small no one could notice it. If it allows you to get a few more mhz out of the proc, it would be worth it. Also you might try swapping in a pci video card to see if that is a weak link. I would also suggest active cooling for the north bridge of the chipset at 150 fsb.

Good luck with that.

My peltier rig gives me about 100 extra stable mhz. It gives me 150mhz extra that are not game stable. A 72~78w pelt would give you better results, but the 55w is much easier to deal with. Condensation should not be a problem with that rig.
Good luck
