Hello,

 

I have a GA MA770 S3 Rev 1.0 Motherboard with a Athlon 4850e Dual core CPU running Windows 10.

 

All works well until today I replaced with a Athlon Phenom 9750 Quad Core 95w CPU.

 

What happens is if CPU gets to 100% usage I get a BSOD about clock watchdog timeout. If under 100% no problems at all.

CPU temps fine 38 Degrees C when using about 40%.

 

I have tried:

  • Reduce memory speed from 800 to 667, same problem
  • Reset BIOS, same problem. BIOS already up to date.
  • Goto device manager right click cpu and update driver, says already latest.

However when I load ubuntu live usb and test. CPU 100% constant no problems at all. So that rules out faulty cpu which I thought.

 

I can try reformat and reinstall windows 10 but takes a lot of time with windows 10. Is there anything else I can try?

Just because Ubuntu runs fine, it doesn't necessarily follow that the CPU is fine. Ubuntu could be failing to detect a fatal hardware error within the CPU that Windows detects. Or perhaps Windows is hypersensitive. Either way, since your previous CPU worked fine, how about asking for an exchange? This will save us time troubleshooting.

Ok I done some testing.

 

I went back ubuntu and ran more cpu intensive tests. Playing 4k videos with google chrome made it freeze.

I increased the cpu voltage a tiny bit. I think was 0.025 Volt higher.

And it is very stable now in both operating systems.

 

I guess some cpu's require a tiny bit more voltage than others? Either way I'm happy.

 

Thanks for your help.
