Newbie here - Did I fry my i5-2500K?

post #1 of 8
Thread Starter 
Hey all -

So we all learn by making mistakes, and I'm pretty sure I made a big one while attempting my first OC. Here is my setup:

Intel i5-2500K
Gigabyte z68a-d3h-b3
COOLER MASTER Hyper 212+
G.SKILL Ripjaws Series 8GB (2 x 4GB) 1600
EVGA GTX 560 ti

Before attempting the OC, I spent (what I thought was) a considerable amount of time reading guides and getting prepared. When I finally attempted it, everything in the BIOS looked good. EXCEPT when it came to setting the Vcore. Instead of an option to set vCore to 1.35, I had the Dynamic Vcore option.

I don't know what the hell I was thinking, but I initially set this to +0.3. Not +0.03, but +0.3. (I know now this should have been left to +0.00 and only increased if needed.) I saved, booted into Windows, and fired up HW Monitor and CoreTemp. With my board, HWMon showed voltages of 1.06 (which I also know now that this is the QTI value, not vCore). I don't remember what CoreTemp showed, but I didn't like it.

Seeing this, I rebooted into BIOS and saw that my voltage was 1.67! Yikes. I reset the BIOS to defaults, rebooted, and all levels were back to normal. I haven't tweaked them again.

I have used my PC a bit since this happened and haven't noticed anything out of the ordinary. But I know every guide I've read basically says 1.6v = instant death for CPU. And I was above that limit.

So here are my questions:
- Since my mobo uses Dynamic Vcore, and I was only logged into Windows for a minute and didn't stress test, is it possible my CPU didn't hit this voltage since it wasn't under heavy load?

- Even if it seems to be working now, is there a good chance I did some serious damage and my CPU will be eating dust very soon?

- Should I attempt to overclock again (now that I've learned the hard way) or leave it at 3.3ghz and just pray for survival?


Thanks in advance for any advice. I used to think I was a smart guy...

you should be fine, as you didn't load the cpu to shoot the voltages up that high for any amount of time.
but yeah you really dont even need to go past 1.45v

And I think you should at least bump it up to x40, you should be able to achieve that with no voltage changes.

Leave it at stock and run intel burn test on it to stress it, i would make sure that it is completely stable before re-attempting an overclock thumb.gif

Meh.. We all forget a zero here and there teaching.gif

If you rebooted and your system is running normal, I would say you dodged a bullet. If you didn't stress it at all, it may not have even reached that voltage. Also, if your system didn't shut down, chances are you didn't exceed the TJmax for that chip.

I would see how it runs the next 24 hours. If you like, run prime95 at stock clocks and see if it's stable. If all goes well, I don't see why you couldn't continue with your original plans.

Good Luck, and watch your zeros lol!

It might have hit that vcore, but only for few seconds. I think ur CPU is fine since u didn't stress it with that high vcore. It's hard to say if the cpu is damage or not. Two thing u can do, take your the cpu and see any burn mark on the cpu and the cpu socket. Second, do a stress test on stock to see if system is stable. (Stress test may fail due to other reason, not cpu problem all the time) However, if ur system can pass the stress test, then your cpu should be fine.

Read the guide that u used carefully again before u oc again. Don't let this incident stop u from oc'ing.

Thanks for the input everyone. I have run IBT and prime95, and played some skyrim and battlefield3 using the stock settings for awhile. Everything looks good as far as I can tell.

I will attempt an over clock again and let you all know how it goes.

With hyper212+ overclock potential of your processor will be very limited.
