I7 Requiring more voltage than it used too

post #1 of 19
Thread Starter 
Hey guys,

could do with a little advice.

My Core I7 920 used to do 3.8 ghz at 1.248v (and then wouldn't do 4ghs no matter what I did, lol) and i would have no stability issues whatsoever.

A while back, last time I flashed my bios and lost all of my saved bios settings i had to re-do my overclock. I could get it stable, but this time at around 1.268v. Ok i thought, fine, no problem. Tested it, was stable, was still decent temps, who cares right?

Well the last couple of days, the comps started giving me BSOD's. Codes seem pretty random, but in general they all seem to point to the CPU. If I give the CPU more volts it does begin to become more stable.

I'm up to 1.28v now, and i'm still not stable. Obviously ive palyed around with other settings too, but to no avail. My 920 has never been great, even at 1.248v it would still hit 75oC under a H50 and now at 1.28v im pushing 80oC.

Has this happened to anyone else? Ive never had this problem with a previous cpu, if anything my old e6600 required less voltage as it got older not more.

Sorry for the long post, any advice/ideas would be much appreciated!

Cheers

Flash to the previous bios.

Otherwise you need to rework your OC to a stable state.

Cpus do degrade over time meaning more volts for the same OC, same goes with other components like the mobo and psu.

Sounds like the new bios fixes are at the expence of more vcore with your chip.

So is it just vcore that can kill your cpu? or are there other settings that could cause it to die quickly?

@MrTOO

Yeah i realise CPU's degrade over time, but ive had this cpu since april, if it carries on like this ill be back at *cough* Stock *cough* clocks in 3 months!!

I might try flashing the bios back to version 4, i liked the layout better then anyway. My only concern is my Steelseries Xai, which doesn't go well with USB 3.0, and rolling back the bios means removing the compatibility fixes they put in place.

Thanks for the reply tho, +Rep

I think this is mainly due to the bios issues. At this voltage, I don't think degrade should have a chance to happen over such a short period of time.

hate to say it, but overclocking causes degradation a whole hell of a lot faster. We know this fact, it is one of the downsides to overclocking.

I guess that is because of higher voltage/temp. But at under 1.3v and nice temp as op mentioned, I think it's just a standard working condition for CPU's. I could be wrong

Thanks for the reply's guys,

I think im going to try rolling back the bios and see how i go from there. Will update this when i'm done too see how it went

I don't believe that.A minor overclock and voltages under 1.4 don't cause any degredation whatsoever.

Well, instead of rolling back the bios I have updated it to a beta version. So far it seems to be doing alot better.

Not to count my chickens before they hatch, but the system does FEEL slightly different. It feels smoother than it has for days, and is quicker to respond after boot. Trouble is, with my ssd, things load so fast, its hard to tell when the system responding badly.

oh well only 12 mins into prime, and streaming video (this combo used to crash it within minutes of a bad overclock) so far, but its alot better than ive had for a while
