hey, i have an E6750 cpu on an asus p5k se mobo and zalman 9700 led as a cooler. i tried running the cpu at 3,2 Ghz with a 1:1 ratio and all seemed stable. CPU temp was 30 degrees in idle and 45 under heavy load with Zalman on barely 1/3 turation power.

what i'd like to ask you is:
1) the chances that the CPU wil lcause trouble if i run it OC'd for a long period of time are considerable?
2) should i not OC the memory and keep it at 800 MHZ in order to get a 1:1 ratio?
3) if for any reasons my CPU fails, the warranty guys will be able to tell i've been running it overclocked? therefore the warranty won't be awarded.

thanks alot

1) it all depends on how much voltage you have going to your cpu, what do you have it set at for 3.2? If you're only at 3.2 hope it's under 1.35v. If it is under then you should be absolutely fine.

2) I'm guessing your memory is rated for 800mhz(pc6400), if that is the case you can OC your ram higher than your CPU and not run 1:1, some argue this improves performance but the only real difference you will see is in synthetic benchmarks.

3) I think they are ways to find out if you have been overclocking, but if you keep your OC to a moderate level you shouldn't need to worry about it as your CPU will outlive the warrenty anyway.

On that note I think you should try a more beefy OC as I have the same CPU and Cooler, though the NT version(different colour, same performance)and can stay stable at 3.6 with 1.33 vcore which is extremely safe considering the CPU is rated to run at 1.35

the voltage is stock. PC PROBE shows 1.30 to 1.33.

i'll try OCing further, but i don't know if the mobo will take it well. i have an Asus P5K SE and i had to change Kingston ddr2 PC 8500 because the mobo wouldn't run them higher than 1000.

I have a eVga 680i SE mobo. I am doing all the Oc 1:1.

And I can't oc this up to 3Ghz without upping the SPP volt (from 1.2 to 1.3v)

At 3.3Ghz, I need to make the core to 1.38125v, not a notch less. The core temp under Prime95 is 49c. (and SPP at 1.35v, not less)

I am new at this and didn't know mobo makes a big difference in ocing even at moderate speed. If I did, I probably would have bought other board.

I still haven't figured out how to get this to 3.4Ghz. My last attempt with the core at 1.4v(core temp under load is 50c with ambient at 25c) resulted in bsod after running Prime95 for about 10 mins.
