CPU OC'd on its own

[theNullinator]

Hey all,

 

For the last few days my PC has been crashing when doing a render in Blender using my CPU. I've been getting a Clock_Watchdog_Timeout Blue Screen of Death.

 

Today I believe I resolved the issue. HW monitor was showing my CPU was at 4.8GHz which is way out of spec for an Intel Core i7-4790k. I never set my OC to this. Clearing CMOS didn't fix it, but using the overclock wizard in the BIOS did.

 

Below are my specs from what I can remember: 

 

Motherboard: Asus Maximus Formula VII

CPU: Intel Core i7-4790K

Memory: Corsair Dominator Platinum DDR3 2400MHz 16GB

PSU: Corsair AX1200i

 

Has anyone seen this sort of thing happen?

Only thing I can think of is someone swapped their old CPU for the new one before selling it to you.

The 4790K is basically as good as it got for LGA1150 - while there was the 5775C, it wasn't as great.

Nope - never.

Did you run Ai Suite 3 or whatever it's called for that motherboard?

I wouldnt worry about it. There is a good chance that it is a feature that comes pre enabled on that board, considering its a high end board and motherboard manufacturers were big on automatic overclocking back then.

Haven't done that. I've had this PC for several years and haven't seen it ever do this. The only thing I can imagine is malware. The only issue I've ever noticed on this motherboard is that on rare occasions it would detect IDE drives when none are present.

Would it detect them or show a popup like "PCIe to IDE controller"?

Nah. Just got an error code on the motherboard's diagnostic display. Can't remember the code now, but the manual said something along the lines of "IDE detect." I re-seated the HDDs and SSDs. That seemed to fix it.

 

As for the CPU issue, it had me really worried. Can't afford a new PC at the moment lol. I figured I either had bad caps on the MB or a dying CPU. I ran stress tests after the fix and it hasn't crashed yet. Before the fix it crashed not even a second into the stress tests lol.
