Is this a common vcore for 4Ghz?

post #1 of 12
Thread Starter 
I just recently put my gpu's and cpu under water, my new specs are listed in the system info. But I OC'd to 4Ghz and set the vcore at 1.3, which I see commonly and just followed what I normally saw. The other day I was just playing around and took the vcore down to 1.25 and completely stable, HT on and ran prime95 for a few hours. Then I decided why not lower it more... so now it is down to 1.2375 and still passing with flying colors... Plus my temps went from 67C to 58-60C(hottest core) which is really nice. But I was wondering if this is common amongst other users, its listed in the system specs but I have intel i7 930. On 3.6Ghz before the new water cooling system I was able to keep it stable at 1.1vcore.

Sounds really low to me- perhaps you lucked out!

On the other hand I imagine about 10 guys are going to come in here and tell you running Prime for a few hours doesn't really prove anything, and most would insist on at least a night of running it on large FFTs for maximum punishment. They'll also likely point you towards 50 lines of LinX, or Intel Burn Test...

I know I passed every mark under the sun with my OC and with moderate voltage and an hour of folding knocked me offline constantly because of very low level instability. Very frustrating!

So before you you get too excited it's probably worth putting that thing through its paces for a bit longer than a few hours. At least then you'll know you won't be in the middle of gaming / whatever and experience the frustration of the bsod. If you Bsod I'm going to wager it'll be a 101.

Hopefully you're rock solid- that's a great vcore / temp!

Well I find that unlike though because games would put the cpu under load, games don't you all 8 thread that I know of anyway so I don't see how that is plausible.

oooohh. IBT! How exciting

I was stable for 6 hours on small FFTs and 6 hours of blend. But failed on IBT. It's really intense

To OP: btw, nice vcore and temps. Hopefully you're stable xD

Someone said that 8 minutes of IBT stresses your CPU more than 40 hours of Prime.

Don't know how much validity is in that statement though.

Well what I don't understand is most people aren't going to stress there cpu's as much as IBT may do so what is the point. That would be like making me hold up a truck for hours to test my strength but in the real world that isn't applicable because I would never have to do that or anything of that sorts.

Then this rationalization begs the question of why you would bother overclocking if you aren't going to do it properly? What you're doing is essentially boasting that you CAN hold up a truck without actually being able to do it.

For that matter, few if any people actually benefit from 4 cores, nevermind 8 running at 4+ ghz. So before we have a debate about practicality... how about we examine ALL of the factors to which it relates. (Scuba diving a 930 for 4ghz, for example).

If you're going to overlock solely to be able to come into the forums and wave the 4+ flag in here then power to you, but don't expect a lot of helpful feedback. If you're in here to ensure stability, then start doing what is required to achieve it.

it sounds normal for a 930 mine needs 1.24 for 4ghz 1.32 for 4.2ghz 1.368 for 4.3ghz and 1.43/1.44 for 4.4ghz these are stable voltages folding.

ha I am not trying to argue and I am trying to make it stable, but I have heard of how ridiculous IBT is, I am not talking about prime95, ect... just IBT. And I over clock because I play alot of heavy cpu dependent games like star craft 2 and age of empires 3. Yeah they don't use all 8 threads, not even all 4 cores but because each core runs at a higher(OC'd) speed then the ones it does uses it get a very good 20-30+ fps boost.
