Slow system after OC

[alfik]

So I think I broke my CPU.

This was my first CPU OC ever, I went up to 4.2GHz on a Xeon 1650 v2. I didn't increase voltage because my mobo doesn't allow it. I was reaching 74 C during heavy load. Everything was working fine until my PC froze and restarted while I was playing Battlefield. I lowered it to 4.0 GHz and it was fine until I decided to download Battlefront 2. While downloading it my PC got slow, there was a noticeable delay on pretty much everything, from running aps to Chrome. Everything seemed to take it's sweet time, one time my system even froze for like 10 seconds.

I reverted my mobo settings to default but the problem didn't go away completely. There is some microfreezing now and then. It's much better than it used to be but I can still notice that some things don't load right away. When it does get laggy, the SSD LED on my PC case is lit, but there is no real SSD usage in the task manager.

Games run mostly fine, benchmarks are just like how they used to be, but there's occasional microstuttering. It does get much worse when I run Prime95, so I suppose it's CPU-related. Temperatures are fine and the memory diagnostic tool didn't find anything wrong.

I thought you couldn't damage anything without actually increasing CPU voltage, but something is definitely wrong. I'm going to reinstall Windows 10 tomorrow and really hope that it will fix the problem. I'm really freaked out that I messed something up in my new PC.

My specs: Xeon 1650 v2, Huanan ZHI X79 motherboard, 8 gigs of DDR3 RAM.

Reset bios settings

 

Id give your cooler a good clean and dusting, and replace the Thermal Paste....new to you...but that CPU may have been seated with that same TP since 2013, and after turning up the heat...you toasted it (the thermal paste)

 

Reinstalling Windows 10 wont do anything if its CPU related or BIOS related.  To truly get a reset BIOS pull your CMOS battery for 30 seconds.

 

EDIT - if you overheated your PC..then turned it right back on, and its not excellently cooled, and this all happened before giving your PC time to cool off - let it cool off and try again.  It takes a while to dissipate that high heat.  Where you monitoring temps during play?

 

EDIT 2 - Im a newb to OC as well, but if you are pushing an OC that you don't have enough power supplied to do so..will cause microstutters etc from my experience of OCing.  What did you use to stress test the OC?

I built this PC a month ago so the paste is fresh and everything is clean.

I just recalled that mobo - that's from Aliexpress, I almost got one of those lol.

 

Anyways, Id pull the CMOS which will reset the bios.  Something wonky could have been changed, or you didn't set stuff back as you are supposed to.
