I got a thermaltake big water cooling system today.
Got it installed without too much headache.
I'm only using it on the cpu until I can get a vga block.

I bumped my fsb from 133 to 166 on p4 2.4c prescott,
getting 25% increase to 3.0.
My temp is idle @ 46°c.
This MoBo (abit IC7-G) lets me lock the agp/pci @ 66/33.

Is there any reason I would need to bump my voltage?

My ram, it looks like got bumped anyway to 208
The system seems stable, going to try some load here in a few.
I'm not too sure what to run to stress test.

Any suggestions?

I attatched a small everest report if you care to take a peek.
Thanks!

Hello SOcRatEs.

Try the Prime95 torture test. You can get it HERE

Regards Howard

Man! Now thats what I call stress'in out! :eek:
Had to back off the OC. to 2.88ghz to get it stable for prime95.

I'm still wondering how far I should tweak the voltage...

Thank you Howard for the link!

Had to back off the OC! Prime95 kicked my booty.
I'm not sure where the weakness is yet. Probably ram.

I get my RMA 6800 gt today and I'm considering a vga water block for it.
Though BFGtech said it would void my lifetime warranty! Now that sucks!
I hear they work well since the 6800 7800 tend to run very hot.
I'm wide open to any suggestions on the cooling mods I'm attempting.

Thanks!

Hi SOcRatEs: Here's a blog I used for my OC. Now it's for AMD64, but so much about OCing either AMD or Intel are the same I think you might get some good suggestions here to help your stability and keep your % increase high. Just skip past all the AMD chip mumbo at the beginning.

I think the basic idea of turning down your memory bus speed (up the divider) to eliminate the RAM as a limiting factor to reach max CPU OC is still relevant, etc. and stuff like that there.

Good luck.

what voltage are you running that CPU?

My board allows small jumps in vcore, .05 on each step.
1.35 to 1.55V
My stock voltage is 1.360-cpuz

I had it bumped to 1.430 @ 166x3.0ghz and 1.450 @ 160x2.8ghz.
both failed prime95 within 10 mins.

I just added a second stick 512 ddr 400 infineon, matched pair,
for 1g ram. I haven't done any OC yet with this setup.
When I lock the agp/pci clock to 66/33
I thought it would also lock the ram, I was wrong.
I still have to figure out the ratio fsb for ram/cpu.
SPD shows my ram @ 166mhz stock. The 2.8 OC gave me 200mhz on ram,
cpu was 160.
My goal is to clock out @ 2.8 20% increase and be stable.
What I still don't know yet is when I increase the vcore does it also increase the ram voltage too?
Still waiting on UPS for new 6800gt.....nail biter

I hope I'm making sense?!?
Thankz

I have the same Processor in which you have and was curios of your results.Look at my gallery

You don't necessarily need to increase the voltage. Just when you hit any instabilities you should increase the voltage. I don't need to increase the voltage in my 3000+ till I get to anything above 2.5GHz.
