Sandy Bridge - Voltage @ Mhz list - Page 38

post #371 of 401
Soon to be stable on my 5GHz OC on my 2600K. Been testing for 20 hours with Intel Burn Test at Extreme, temps between 70-80*C with my H70 cooler and 800D case. Realy good CPU, glad i jumped from a AMD Phenom II X6 to this one biggrin.gif

Hi, need feedback from expert here...

1. I'm aiming the highest and most stable i can get out of my 2500k. I've managed 4700MHz @ 1.39v and successfully run IBT at Very High setting.

2. I notice lower temp when I lowered CPU PLL to 1.75v. Is this ok ?

3. Do you guys think that my temp is too high ? I've hit 79c maximum while doing LinX. Is it safe for 24/7 use ?

4. I have not tried Prime95 blend with this setting yet, but my last setting (4500@1.32v) it BSOD after 6hr. Is it considered unstable ? Does this mean it'll BSOD during 6hr of gaming or what do Prime95 test represent actually.

It's a lot of asking, and thanks in advance.

It really depends on what you do daily but I suggest backing down your oc to get some better temps for 247 or get a better cooler. I run 4.5 247 and never hit over 50c load temps. You should just back it down to where your load temps are like 60-65 max imo. The difference between 4.5 and 4.7 is minimal so the temp decrease would be worth the speed loss.

Now the other thing to keep in mind is that most things dont stress a cpu to the fullest like stress tests do. Run your normal daily apps like you would and monitor temps then. If it stays below 60-65 I say keep your current settings. Unless you want to bench or fold 247 then go back to the first paragraph.

This is just my "expert" opinion (im not near expert but i think others will agree with me).

My real suggestion is try and get a better cooler if you are determined to run 4.7ghz+ for a 24/7.

I already said it once but you're overrating temperatures like crazy. They're designed to throttle way before any kind of damage happens. These chips like to throttle at about 90-95c, so keep your temps below that and you're just as much in the clear as if you were running them at 60c.

Yes, I doubt you get anywhere near that temperature during normal use.

First, Prime95 should be your goto app of choice when testing a SandyBridge OC. It seems to find any issues with an OC where other apps do not, and usually very quickly. I can often find out in a matter of seconds if my OC is not stable by simply firing up Prime95. To answer your question about stability, yes, technically your system was unstable even though the BSOD occurred after 6 hrs of Prime 95. A stable system should never BSOD no matter how long a stressful application runs. With that said, in realworld use of your system, I doubt you would ever have any issues.

I've found prime to be not as effective as folding. Ive passed prime for hours but then bsod with folding in less then an hour

I'm currently trying to get 4.6ghz completely stable @ 1.344v. I thought I had it at 1.33v after it passed 50 LinX runs on MAX and 6 hours of Prime95...good thing I left Prime95 go. It failed a little after 6 1/2 hours in.

Does anyone know how much the PLL voltage affects temps? And how far can I lower it w/o affecting my overclock?

PLL voltage won't drop your temps by much but lowering it to 1.76 tends to help alot of overclocks. 1.73 seems to help even more with some people but it won't even boot with others.

I tested PLL voltage at 1.75v and 1.8v and its the same CPU need same voltage for 24h stable clock
