Windows 7: BSOD - Clock interrupt not received on secondary processor

After running Prime95 and Memtest86+ as Jonathan_King recommended, can you Download Core Temp and post the CPU temps?

Have you checked the CPU temp before?
AMD CPUs usually run cool, 59 C is pretty high.

Post using the snipping tool, type 'Snipping Tool' in the start button search box and hit enter.
Select the area and save to a convenient place.

Post it here using the upload as explained: How to Post a Screenshot in Seven Forums
Check if your RAM is in 'Unganged' mode.

Easy way to check is to D/L CPUZ and post a snip of the CPU, Mainboard, Memory, and SPD tabs.

Also, go to your BIOS and tell us what the CPU, RAM and North Bridge (NB) voltages are.

Let us know if you have any questions.

Okay, it took a while but I ran the tests suggested and no errors at all...

Any more thoughts? I appreciate the assistance so far...

Check your CPU temps and post the info requested above in post#11.

Okay, here are the temps...

Speedfan is what I used for the temp readings, hope that works for you guys. Its been my best tool in my toolkit for years.
GPU 72C, CORE 62C.

Before I started the load test, GPU was 62C and the CORE was 51C
After I stopped the test it went back down quickly to the starting temps

Memory is in ganged mode.

All voltages are set to auto. I don't overclock anything that is why this is so hard to figure out for me. I could see if I was tweaking...

Anyways, thanks all for the support so far.

What is next?

Is this your CPU?
AMD Phenom™ X4 9500


If it is, check the voltages on the above link, they are 1.10/1.15/1.20/1.25V.

Yours is showing a voltage of 1.312v from CPUZ and Speedfan.


Your max temp is 70 C, from the above link.


Your CPU is running too hot.


Go to your BIOS and change the VCore to 1.20v.


If your system won't run at that voltage then bring it up by 0.02v until it is stable.


You will see much lower CPU temps.
Check it with Core Temp to be sure.

Once the CPU voltage is down to a reasonable level and stable, Run Prime95 and keep Core Temp open and watch the temps until they stabilize.


You might need to change the RAM to 'Unganged' mode, this will make your RAM more stable.

Adding RAM from 2 X 2GB to 4 X 2GB will sometimes require a north bridge voltage bump.
We will look at that next.

Okay two fan units later (antec vcool, antec spot cool - positioned directly over vga heatsink), 1 voltage adjustment to 1.2 v and unganged the memory, here are the results.

Does lower voltage mean slower proc tho? (Sorry for the newbie question...) Seems slower, but maybe its because I have consciously made the changes.

I have not run the load tests tho, that is next...

Lets see if she makes it through the nite without BSOD's!

The Core Speed is how you over clock the CPU, you adjust the voltage to make it stable.

Low voltage will cause it to stop working, too high voltage causes excess heat.

Your CPU speed is the same when you adjust the voltage.


Check in your BIOS for the RAM and NB voltage, post it here.

As much as any avid computer geek hates these words... Underclock your CPU. I have the same CPU/mobo.. setting to auto BSOD to insanity. for some reason It was autoing to 5.5 O_o so CPU-Z said anyway. As far as i am aware its supposed to be 11. anyway I set it up to 6x and I haven't had any Clock_Interupt problems. just an accasional IRQL stop O_o. I'm going to step it up a little bit over the next few days to see how high it will stay stable at..

It took me a little while to weed my problem out, I hate the conclusion. But it's solved..

Just before i found the solution, i broke down and ordered a 9750 since it has no complaints of this problem.. LOL now im debating on going through another journey of taking the water block off (4th time since I've built this computer. And slapping the non problematic CPU in. ^_^

Hope this helps.. Also, keep your cool'n'quiet off, C1E doesnt make a difference. If your not going to virtualize any OS's turn it off to.
