Water Cooling Temp

That makes no sense. How much Vcore is required is not affected by the efficiency of the cooling solution.

The Vcore required might change slightly over time, but a new cooling kit won't magically make it capable of running at lower voltage, rather it should make running at a <i>higher</i> voltage more feasible, as it can cope better with more heat....

They're not bad for load temps I'd say. This morning my CPU temp was 38C after running Folding@home all night. (System Temp 25C). So a Prime95 load would probably be 40 - 42C, and that's on Air....

but then you're running at .3V higher Vcore than me, which is a fairly substantial increase. at ~1.575 V @ 2.25Ghz I hit high 50s load IIRC. Now the weather's getting cooler, I'll clock it back up near there soon , so I'll know for sure then...

Nah, your edit time is almost 5 hours after my post time.

Honestly Ned, if I put your cooling on my xp-m, I'd be running it at 2.6+ gigs. Maybe you got a bad chip, or maybe you cranked your voltages a little early. See if you can drop the v a little more.

That sucks, my samsung ram is @ 220, with 2.5, 3, 3,7 latencies.

WRONG!

This affected me most when running an overclocked PIII, the COOLER the CPU is the LESS vCore it requires to remain stable! I did extensive testing, the fact is that when your CPU is near the edge, you can raise vCore OR add cooling.

I think it has to do with heat: Increased heat makes a CPU act more like a conductor than a semiconductor, the excess leakage weakens the signal, in a viscous cycle, and the only way to curb that cycle is to reduce HEAT.

Now you're going to force me WAY back in my memory, I think my PIII 700 required 1.90v to run 150MHz bus at 55C, but only 1.80v to run 150MHz bus at 48C.

Remember that CPU's become less stable when hot, and more stable with an increase in vCore. Those are things you can agree with, right?

This lends itself to the following circle when you've reached the limit of the cooling: More heat=less stability=add more vCore=more stability (until the cooler heats up)=more heat=less stability (cooler has heated up) etc etc etc until you blow the CPU. In order to get out of that cycle, you jump down to LESS HEAT and viola, you're stable without raising vCore.
