Attempt to OC Presler 930

post #1 of 24
Thread Starter 
Ok, 1 month ago I bought a brand new watercooled rig with an Pentium D 930 and an Asus P5N32 Mobo. The idea was to test it fot about a month to check for any errors and then help the poor old 3.0 Ghz to about 3.5-4.0 Ghz so that I'm able to render a hell lot quicker . Problem is that it's not quite working as expected and i'm only able to get the FSB to 850 mhz and now i'm still working at a "lousy" speed of 8.2 Ghz. My temps aren't the problem (6 degrees idle, 20 degrees load) and the voltage is 1.4V. If I set the FSB higher (900 mhz), the thing won't boot, gets stuck and I get an -overclock failed- message .
Could the problem be that I already toasted the CPU? Because at the beginning I've set the voltage at auto and the mobo has put 1.63 volts on it . It was running at this voltage for about 3 days (that is 5 á 10 hours a day).
What is my problem???

Ins't that the -SLI board? Maybe P5N32-SLI uses a NVIDIA chipset, not an Intel one. If so, that's likely your problem. I seem to recall a couple threads about those boards just last week regarding their poor OCing. And I know they have mixed reviews on Newegg and lots of posts regarding them on the ASUS forums.

He must have his terms mixed up a little bit. Why don't you give us a CPUZ screen shot so we can see exactily where you are.

Thanks for the assist, it is indeed a Nvidia chipset, is there any workaround for this problem? or did I just buy the wrong Mobo ?

EDIT:
here's the CPU-Z screenshot
I can't even get past the standard 800 Mhz FSB now, tomorrow i'll try to start with a 1.2V, raise FSB, raise voltage, raise FSB, etc.

The 8.2 Ghz should be 3.2

Ok you need to start from scratch. But first you need to fill out your system specs located here(this will make it easier for people to help if they know exactly what you have in the Rig)
Then just simply Reset your bios via a jumper or by pulling the battery off the board for a few minutes, then start from scratch. I dont know how the SLI board is setup, but its should have some of the same settings as most. You need to adjust the overclock to manual everything(fsb, ram, voltages-Vcore the lowest minimum for that CPU 1.25?, and so on) then simply start raiseing the FSB by 2 (200-202 and so on) just make small adjustments. Download this, and run a 1m everytime you boot. You should only raise the Vcore when needed to make the system stable. You will reach a point when you need to start adjusting Ram timings and voltage's, but when you get to this point hopefully you will have your system specs filled out so we can give some pointers on what to change and so on. Good luck and Welcome to the Forum

I had a P5N32-SLI Deluxe and I reached 1000FSB stable and booted it at 1066 so its not THAT bad at overclocking, maybe it doesnt support your CPU though....
