New to this, 2600k @ 4.4Ghz

[DrD0ctor]

Update: I actually had to reformat because Windows wouldn't start. I tried changing the voltage but my PC wouldn't post anymore so I pressed the reset cmos button on my mobo, from that point on Windows would give me that error saying it could not boot and a recent hardware change may be the cause, I tried everything but couldn't fix it. Anyway, I formatted and am back on track now, but maybe someone has an idea of what may have caused this problem?

Anyway, back at 4.6GHz and it's running quite smoothly, highest temp is 84, which is lower than my first try at P95 @ 4.6, heres a screen cap. Sorry if image is too large, let me know and I'll resize.



Also note that last time it BSOD'ed at around 45 minutes, not sure what's more stable this time around but so far so good

Have you tried LinX? My opinion is your volts are too low, and your CPU too hot. For 4.5ghz most people need around 1.35 volts. Also 84c while running P95 is a little too toasty. I do not suggest over 72-75c in P95, and up to 80c in LinX is acceptable. You can get by with higher temps but if you're on the edge with volts, problems will rear their ugly head.

Not sure I can say I've heard of LinX, I'll look it up.

Came back from class and got greeted with a BSOD, bccode 124.

What would you recommend? I thought the V8 cooler would be capable of maintaining relatively cool temps up to 4.6. My case is the Coolermaster Sniper, airflow is great in this case. My thermal paste is antec formula 5, could that be it? I don't think it's good paste, at least compared to AS5

Edit: I will be disabling spread spectrum in a few and trying to bump vcore

currently running LinX, the max temps are:

72C 81C 79C 77C

Test is running with maximum memory, problem size is default

dont bother with linx, IBT etc. p95 is the best SB stress tester bar none, the only drawback is it takes a long time. 0124 is not enough cpu voltage. raise it 2 steps and try again.

Try reducing llc, the chips I tried didn't like ultra high (75%) llc even with fixed/manual voltage and needed much more overall voltage to be stable at idle otherwise it was bsod 124. Along with reducing LLC running in offset voltage seems to work well as then you don't have to put up with much higher idle voltage.

The Noctua NH-D14 is very highly rated for these cpus, though they are huge.

I can definitely recommend the Corsair H100 as well. Using only the stock fans in a push configuration, my 2600k maxes out 1 core at 73C (RealTemp) at 4.8GHz/1.4v with the rest at 69-70 in a P95 blend test. I also like the nice clean look it gives your build.

your cooler is ok for 4.6 if you want higher you need a better cooler. the v8 aint a great cooler, but its not a dog either

fixed voltage doesn't work for me, I tried it and my PC wouldn't post, I think I had it at 1.3 and it screwed everything up. I'm on +20 offset now @ 4.4GHz, I'm thinking that I should just keep it here but I feel like I should be able to squeeze by with 4.6, but I don't know.

also: I just bought the V8 so getting another cooler isn't an option, especially considering its price.

@ TK, since I'm not using a fixed voltage, what would be the equivalent of your suggestion in terms of the offset voltage setting?

Thanks guys, you're all awesome

PS: I realize the V8 isn't top in class, but I was under the impression that it was mid/mid-high end cooler, either way I upgraded from the stock intel cooler and there isn't even a comparison between the two. Your description of it seems reasonable, I wasn't expecting anything breathtaking, I just wanted to get it to at LEAST 4.4, and I know that speed is guaranteed, so in the end I'm satisfied. And I honestly wouldn't have gotten as far as I have without your help, I'm easily more knowledgeable on OCing cpus and temperatures than I was 2 days ago, so again, THANK YOU!

Im no expert in off set, but how I do it is find my stable load volts and mess around with the off set until I find the same load volts. mine is +.85 or .90 every chip is different. other people could prob help you better with that
http://forum.overclock3d.net/index.p...de-and-thread/
you prob wanna have c1 and ss enabled and c3 c6 disabled

I see, if using offset you'll need to consider what LLC setting you are using before adjusting the offset as too high an llc will cause bsod 124 here too, also make sure c3 and c6 are either set to auto or preferably disabled.

[DrD0ctor]

what do the C states do? That has nothing to do with clocking down when not being used does it? I'm reading up a bit on it but can't exactly figure out what function it serves for.

Also, my LLC is @ auto

Edit: Checking out that link now, awesome stuff, I'll be reading up on this. thanks TK

[BlackZero]

Not sure what LLC level 5 translates to but try to choose a level that keeps it to about 50%. Also c3 and c6 put certain parts of the cpu to sleep when the system goes into lower power states, this brings instability when overclocking and only brings minor power savings compared to c1e. c6 in particular goes one step further and reduces idle cpu voltage even further and this will more often than not cause issues when overclocking.

[DrD0ctor]

Well I've just completed 1 hr of p95 @ 4.5, I made all the adjustments you guys have suggested (LLC @ lvl 3 which is about a 50%) and I've cleared the 1 hr mark on that, so far so good! I think my next few attempts will end in a stable 4.6 after a couple adjustments. I'll run p95 overnight @ 4.6 and hopefully there wont be a blue screen when I wake up *crosses fingers*

Still a little concerned with hitting ~85C during p95, but considering the load it puts the CPU under I think average every day temps and gaming temps should be fine (or I hope)

[DrD0ctor]

BSOD'd last night @ +.035 offset, tried again this morning and BSOD'd again with a +.040 offset again with a 101 bscode, not only that but temps really shot up into the 90's, not something I can really get jiggy with tbh. I'm going to settle with 4.5 because that was my last relatively stable clock, there's no way I'm adding more voltage when that thing was pumping out 90+ degrees with what I had. I'm cool with 4.5 GHz, it's a decent compromise

[---TK---]

4.5 looks like your max dr who lol

[DrD0ctor]

Lol I'd say so, sir. Thanks again for walking me through it, not only have I learned the basics of manually overclocking but I've actually achieved the best OC I can get with my new cooler. Many thanks! *flies away*

dont be a stranger bro. use the knowlege you learn to help others obi wan
