****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



I say carry on until you start hitting 85c in realtemp and keep the voltage under 1.45v for air cooling, that's my opinion.

By the way, it's looking good so far.
Like is there any way to bump something else up to make the settings work without bumping the vcore? Like another voltage that will let me boot and run stable but not pushing the vcore. Because I can bump my multiplier to 46 and stay at 1.36 volts its just I get BSOD 124. Is there something else I can do?

Also, out of these settings, what should I enable/disable?

C1E
C3
C6
Speed Step

Is it good to run the CPU at like lets say 5.0 always and not have it downclock to a low setting? Does it hard it to run at 5.0 constantly?

If the cpu needs more vcore there is nothing you can do except for adding more vcore.

You could try messing around with the PLL votlage and VTT like I instructed in the other guys thread and find a sweet spot, but it doesn't guarentee you a lower vcore but it's possible.

C1E and Speedstep should be left on at all times, it doesn't effect overclocking or stability and can help overall temps, power consumption and the longitivity of your chip especially when you switch over to offset votlage once you have found 'your' overclock.

Like I mentioned there is no reason to run the overclock 24/7, let the cpu decide when to do that when you're using the rig. Mine downclocks when using the internet and minor usage, however when gaming or doing something cpu intensive it jumps straight to 5.1ghz using the speed when required. So bottom line is leave C1E and Speedstep enabled.

C3 and C6 reports should also be left enabled unless you're using offset voltage at which you will have to disable them to tackle idle random bsods.

Hope that helps.

OK QUESTION TIME!

I feel like heat is my enemy atm. I got it to run and boot and run prime95 with 4.8 and 1.465 but I got BSOD 101 what does that mean?

I just kinda suicide ran it because I knew it would be hot. I got to around 85*C so I think its impossible for me to run 4.8 without some watercooling. I feel like one I get to 4.8 I need to blast the voltage up to get it to be stable and it just gets too hot. I still don't break 70*C in battlefield 3 at 4.8 though. So I dunno prime95 just makes it so hot.

I'm going to play around with 4.7 if its too hot I'll have to stay at 4.6 untill I get some better cooling.

I'm thinking of returning my hyper 212+ and gettin g the noctua ND h14 or whatever its called but I dont know if it will fit on my ASRock p67 Extreme4 gen 3. ANyone know if it will fit?

Here are pics of fresh AS5 I put on my Dark Knight and i5 2500k. The lapping on the Dark Knight is pretty rough, so I rubbed a light layer of AS5 to fill in the gaps and small nooks in the HSF for better conductivity






Below is my temps and OC
