Default clock settings for i7-950?

[martinlest]

Hi. I have a PC (5 years old now, I use it as a second machine) which has been working just fine until this week, but when I boot (into Windows 7 (x64) ) the PC soon freezes up completely, or I get a BSOD (the PC rebooted - I have changed the settings so it won't in future and will note down details). I do have one crashdump file (ntoskrnl.exe problem), but what I want to try at the moment is to return the clock settings to default. The M/B is a p6x58d-e. Googling has found lots (of course) on overclocking but all I can find is the default CPU Voltage (1.18).

The P/C has always been overclocked with no problem, giving a stable 3.8GHz. The settings I was using are below. Last week the O/C failed and in the BIOS the CPU Voltage of 1.30000V, which had been OK for years, was in purple, indicating a problem. The highest I could get the BIOS to accept was 1.20000. But I made no other changes to settings in the BIOS - maybe this is where the problem lies, changing the CPU Voltage alone?? I can enter the stock value of 1.18000V for CPU Voltage, but what else to I have to change in the following settings to return the PC to its default clock settings (DRAM Bus Voltage???). As this is not my principal PC any longer, I have no reason to overclock, if that is what is causing the problems now. (Any other suggestions as to the cause, otherwise?).

I checked Core temps BTW - all are fine under load. Running an AVG anti-virus scan has all cores running near max though, is that normal?? The PC freezes up after a while...

I am also running Memtest84 - no problems shown so far.

Thanks!

Martin

Hi,
Does this look like what you have ?
If not you might be able to just remove and reinstall the cpu and that should also reset everything :/

Removing the CPU is not an option for me. Once upon a time maybe, but that's the best way for me to trash the PC these days!

Hi,
Actually oc'ing pretty much will trash a cpu well before simply reinstalling it and reapply thermal paste :/
But yes if you're all butter fingers you might run into an issue if dropping it

You can also flash your bios how risky is that

The PC was supplied overclocked when I bought it, and as I say, it's worked fine for 6 years now I think. ASt the moment, having stressed the RAM under test (I am tempting fate by writing this, I know), I have had no issues with BSOD or PC locking up. I'll see how it goes. Will post back if and when I get issues again.

Thanks.

6 years of over clocking :/
Seems you've gotten it's worth plus some.

Got a new PC last month - state of the art for gaming - but the old one is still a real trooper!!

Well as I see it you have three options
Ask the person you bought it from
Ask gateway support
Flash the bios

I would imagine if you enter the bios there will be a optimize defaults listing possibly F10 ?

 

[martinlest]

I didn't see options to reste when I looked this morning, but I'll look again. For now I'll leave things as they are until the issue reappears though.

I imagine after this long the thermal paste is history
It's really no big deal to remove and reapply cpu and thermal paste and there's plenty of youtube videos to show you how if you need them.

The CPU isn't running hot - around 60 degs when running MS Flight Simulator X is pretty OK.
