D975Xbx2 - Lowering CPU Voltage

Post by Hobbes » Thu Jul 05, 2007 10:58 am

I currently have an Intel D975Xbx2 Motherboard and an E6600 C2D CPU. Now my problem just started happening a couple days ago. I was using my computer and suddenly it turned off. I tried turning it back on and I heard these 4 bios beeps and it shut off again (the beeps went High-low-High-low). I now know that this means that the timers on the board were reset due to some reason, I was unsure of why, but I unplugged the PSU and replugged it, and it seemed to work fine.

Now a few days later it happened again, but this time when I turned it on, I was informed that the CPU overheated and it shut itself down to prevent damage (sweet!). However I can't have my computer just shutting down all the time, so I need to fix this overheating problem.

I already applied some more thermal paste and I reset the heatsink, however I am told that I need to lower the voltage in the bios. Could someone with a little experience with the D975Xbx2 guide me trough this? I hate blindly going into the bios of a mobo when I honestly have no idea what I am looking for or doing in there!

Thanks a lot guys.

EDIT: Alright, I figured out how to do it and I lowered it to 1.300 from 1.325. Will that help? I am not seeing a decrease in temp, I am still getting around 30C idle.

And on another note, I am not using the marvell raid ****, how would I go about turning that off? I don't want it to do that whole array checking thing durring startup.

30oC idle is about normal.

What are your load temperatures like? (Use ORTHOSto stress your CPU and to also make sure that your CPU is still stable with the reduced voltage)

Orthos is running right now. I'll let you know the results when it finishes.


Okay, after an hour of stress testing I reached around 38C as my load temp.

I don't really understand it though because I wasn't getting much higher temps before and yet it was still shutting down.

Check your systems logs, r-click my computer and go to manage. It might show why it was rebooting.

What power supply are you using? Also try stressing the GFX with 3dMark and your RAM with Orthos (blend test)

Those temps are well within the accepted range for core 2's. They should shut down at 80oC+ so I don't know why your motherboard was telling you that it was a thermal shutdown.

Depends on what is being used to measure the temps... i would suggest you try running the tests with core temp on i think that probably the most accurate of the temp programs..

Do you have the Intel Desktop Control Center installed? (Here is link for the Vista 32 version - http://downloadcenter.intel.com/Detail_ ... 2&lang=eng ) This will allow you to change the temperature thresholds for the fan controls and could help with your heating problem. However, it doesn't appear that the temps you are reporting are excessive.

Okay, I'm retarded. I had the [email protected] program running the whole time. I turned it off and now am down to 50C and 47C idle. I'm sure thats good enough for what I need.

But now that I have regular temps, is there any way to get it down a little more? Or is that about as low as its gonna hit?
