i5 2500k Wanting more Vcore

Hi im totally knew to this overclock stuff (and forum) but i had my i5 2500k stable at 4.4ghz with 1.345 vcore but then i got a BSOD playing gw2 when i had it stable on IBT maximum. I kept notching the vcore up bit by bit and the only stable vcore i can now get at 4.4 is 1.375? so my question is why would my cpu suddenly want more volts? thanks.

As CPU's degrade over time, they require more vCore. Most manufacturers find a stable vCore, 1.315 for example, then make 1.345 the standard so it will still perform in years to come. Its normal.

Check your temps though.
 
its a poor overclocker and degraded quicker...

as above i would watch temps and knock the speed and voltage down knock it down to 4.0ghz... how your other voltages??

is it just with single game or under stress also??

has it BSOD once??

Did you take note of the error code??

It BSOD first of all on GW2 that caught my attention then i ran it on IBT and it crashed again and wouldnt go stable until i reach vcore of 1.385 thats what im running now and was stable on IBT on high with 20 runs. I dont see how my old overclock could have been bad though thats what i dont understand the temps were good and on that overclock it didnt BSOD on IBT on very high for 20 runs
 
Also i got this bundle from ocuk and as i had to flash the bios and the ocuk overclocked profile went they had to send me the info through email and the only thing i changed on that was the Vdroop cause they told me to turn that off and i heard thats not really good for the cpu so ive kept that on. But apart from that its what theyve given me, thought i was doing right for my cpu to last longer
 
No dont think they have, max ive seen it go was like 65c on gw2 or farcry3. To be safe i have put it down to 4.0Ghz the max vcore HWmonitor is showing now is 1.305. I wouldve thought that wont harm it at all? Should it last a good while now its at a lower overclock?
 
run Prime 95 and keep close eye on temps. have a hardware monitor running also like CPUz and report any fluctuations in voltage. (see what it drops down too and peaks at)

did this all start when you reset the bio's???

in worse case scenario you have a poor clocker keep it at 4.00ghz and 1.305V
these cpu's should be good at 1.35V 24h imo and 1.40V very tops... keep it running like this for a month then run prime again if it fails in a months time deffo degrading.

was it a pre overclocked system by OCUK. if so you can say its not holding its overclock see if they could send you another CPU. .

[EDIT] ingame 65 is high what Heatsink do you have (65 is within safe limits but with good heatsink temps should be around the 50 55 range while gaming)

Started about 1-2 month after i reset bios and ill get on that prime95 tonight and let you know how it goes. Ive got some £15 that everyone was loving, thinking about going watercooler anyways and yeah was a pre overclocked bundle from ocuk.

That 60-65c from gaming is mainly from GW2 WvWvW so its huge battles and runs cpu real high load.

Wow 1.345 & 1.375 for 4.4, mine is running 4.6 with 1.315, was stable but upped to flat 1.32 my temps a little lower, max temp is about 74 whilst under stress test on p95 for 12 hrs
 
hi if load line calibration is set on max u could bring it down one not sure if it will help but with my asrock mobo its to aggresive and give to much voltage
 
Thanks for all the replies guys, Ive sent a webnote to OCUK about it cause its rather crap how ive not got the OC that was sold to me. But ill send the temps and stability from p95 tomorrow. Thanks again

I've been sent that from ocuk. Isn't it a bit of a wild oc? First of all without vdroop I heard that's a no no? Let alone with such a high vcore?
 
I've just gone with that without Vdroop. I thought to myself it cant be that flipping bad cause everyone else who buys a overclocked bundle would complain like mad if the vdroop died on them and wasnt good for the cpu. thanks again all who took the time to give me advice.
