Can updating BIOS mess up my CPU?

post #1 of 9
Thread Starter 
I updated my bios for Asus Z77 Sabertooth and my old OC profile is being weird.

I had 4.8ghz @ +0.185 offset, LLC 75%, etc etc..

Now when I go into windows I am seeing my CPU-z being weird. When I first boot into windows, it shows my core speed at 4800mhz, and the voltage is 1.400v.

After stuff is done being loaded, the core speed drops to 1600mhz (normal speedstep) and the voltage is 1.192-1.200v. When I start up prime95, the core speed is 4800mhz and the voltage fluctuates between 1.376 or 1.384, with majority of the time it being 1.376 with a custom test 12gb ram, 8-8 cpu intensive.

Any idea what I should do?

Is my CPU busted? Did I break it?

I had tested my i7 3770k for 24 hours prime95 blend stable using 12gb ram and my manual voltage was 1.384. After some tweaking I found that I needed +0.185v offset to make it stable.

What do I do now?

Can someone please help me so that I can get my vcore to 1.384 with the proper offset? What do I do? Help me please!!

Your CPU is fine. It could effect an OC, yes. You may have to revisit your OC specs if the system is now unstable.

However, it does not look like its BSODing though. See if you can tune the vcore to lower numbers.

You might hit GPU limitation. If you want to test for stability, use prime 95. If you want to test for performance, use something that is CPU limited.

If you are not getting any BSOD'S with that OC you are fine.I would try using OCCT for your stress test becuase it shows voltages as well as temps and core speed.If you pass after 12 hours I would say you are find..But to give it a real test try folding for 24 hours SMP only if ya pass on that your OC is stable.
