I could run you some tests with my sig rig Just name the software.

I dropped the VCCIO and saw about 5c lower temps. I think 5GHz 1.375V is still considered a good overclock on air if I can get some Prime95 results

How much did you drop VCCIO in order to get a 5c drop on the cores (Or hottest core?)

Hey Munaim , just try everything you and other members said, everything is going well, i just thought 1.47 is a little high but i was reading that its good up to 1.55?

1.34 - 4.6
1.385 - 4.8
1.47 - 5.0ghz <- my tempt is around 64-73 is that good to go, for prime testing?

From 1.2V to auto, which was ~1.07V. To be honest, I'm not sure anymore if it dropped the temps or if I'm being paranoid, lol. But as long as the stability didn't suffer, lower temps are okay by me

This is my opinion, take it as you will:



****Max Safe Voltage and Temps****


Before I go into this, I just want to say that this is my OWN opinion and take it as you will.

No one is absolutely certain of what the safe vcore is for the sandybridge chips. What I can tell you is that many say the max safe vcore for these chips are 1.3 region, however, intel states that the max 'VID' is 1.52 and many say that around 1.4 if your on air and 1.45 should be the max if your running water cooling. Personally I will not go above 1.5v for 24/7 with these chip but that is totally upto you. The main thing to understand is that 'YOU' have to come up with the conclusion of what the max is. That way no one is blamed if the chip degrades (none reported so far, even with so called 'high 1.4+ vcore')

Those that have killed or degraded their cpu's have done so through either by their own fault, running sucide runs with crazy voltages and by not having substantial cooling for their overclocks and voltage or for reasons like their mobo or PSU causing shorting and also BIOS bugs.

Please remember that not all chips are the same, some can do high overclocks with low voltage some cannot.

Regarding temps, CPU throttles at 95c, some say keeping it below 85c is good, some say keeping it below 80 is better, other's say below 75c is really good and there are quite a few that say 70c should be the max. Which ever one your comfortable with and if you have substantial cooling, YOU DECIDE YOUR MAX, just remember it throttles at 95c. If for example you hit 85c in stress testing then in everday usage it shouldn't be higher than 75c which I think is fine, I personally like to keep mine below 70/75c during general everyday usage

EDIT;

That overclock is actually pretty impressive, first glance was just to see the format of your screenshot, but now looking at it clearly, I'm very impressed!!!

Nice low temps and an amazing low vcore for your overclock. +rep!
Awesome

Ambient 16c(kinda cold where you're sitting inside with a jacket and long pants on even tho it still feels like the middle summer outside) helps quite a bit, think the coldest Prime run I did peaked at about 58c with idles in the upper 20s low 30s. My average under load being around 65c.
Did disable the iGPU tho, but that didn't have any effect on temps or core voltage. Pretty happy with it.

Let that sit for a bit, then try for that infamous 5Ghz.

Got the d14 installed.
Put in what i thought would work. Didn't have much time yet.
Will try to get higher when i have time.
This will do for now.

munaim1,
I have a question regarding the help you gave someone in this post
http://www.overclock.net/intel-cpus/...ng-help-5.html
When you worked out the sweet spot for VTT and PLL @ a 47 multiplier, does that sweet spot only apply for that multiplier or would it be the same for say a 49 or 50 multiplier?

Question. How does disabling the igpu assist in OCing our Sandy Bridges? Does it lower specific voltage requirements or lower our temps any?
post #4610 of 10702
I just had a 124 BSOD (while GPU and CPU folding) on settings that were previously folding stable for weeks of 24/7 folding (GPU and CPU), and was wondering what is on my to do list of things to check if it happens again. First thing I did was roll back to the 266.58 drivers because I was on the latest beta BF3 drivers which have caused BSODs for some, so I'm hoping that was all it was. If not though I know to start low with my PLL and work my way back up as that could be one possibility. After trying that what should I do as far as the VCCIO as I understand that could be a possible culprit as well, should I lower it or raise it? Past those two I noticed the BSOD section says could be QPI as well but I'm not familiar with that one, is that for SB systems? So I've eliminated GPU drivers, and I kinda know what to try as far as the PLL goes, but any info as to what I should do as far as VCCIO or QPI if this happens again before resorting to raising vcore?

Other relevant info is I'm at 4.7Ghz @ 1.375 manual volts, ultra high LLC, 1.352 lowest voltage under load, 140% current capability, RAM is 1600Mhz 8-8-8-24 1.5v XMP. Everything else is still on auto as far as I remember such as VCCSA, PLL, VCCIO, etc.

Thanks in advance.
