i5 2500k and CM 212+ are these temps okay? - Page 2

post #11 of 33
I'd have a look at a BIOS update, see if there are any new releases that might fix this issue. I had to flash mine to make it take it. Also, try settings your power options to performance rather than balanced.

I did reboot and it started working. The problem now is that my PC blue screens after about three seconds of Prime95!
I'm going to mess with the settings a bit now and see if I can find a stable OC.

EDIT: Oh and thanks for suggesting CPU-Z. It's detecting the clock at where I set it.

It's kinda frustrating.
Any ideas?

Also, I downloaded CPU-Z and am using it to monitor now.
I have to say I find that these SB chips are mildly retarded in that area. I disabled speedstep C1E EIST disabled OS ability to change clocks, etc. when I was doing chip binning, and I'd boot into windows and CPU-Z would mark my CPU @ 1600MHz.

Now I've finally settled into my chip, and I actually enabled speedstep and C1E and all that nonsense because I want the power saving options, and my chip runs 100% of the time at full clock/volts. Go figure.

Hahaha... oi, I understand. I've worked with some quirky tech before outside of OCing.

I have a question for anyone with an answer... I've read that programs aren't always accurate at measuring voltage... nor that motherboard are always setting the voltage to be exactly what they say it is. This makes me nervous.

I set core voltage earlier to be 1.3v, and CPU-Z was detecting something like 1.28v. How nervous should I be? I've heard of some programs being off by as much as 0.15v before.

Thats just vdroop no need to worry about it, its supposed to do that under load.

Oooh okay, thanks. I did a bit more research on vdroop and voltage monitoring and it made me a lot less nervous.

UPDATE:
Right now, after a night of Prime95, I'm running stable at
4.2ghz
1.284v (Set at like 1.295 in the BIOS? Not under load.)
1.272v (With vdroop. Under load.)
and max temps of 58/60/61/59
The voltage is probably higher than what is needed at this level. I haven't tried to find the lowest possibly voltage quite yet.

I'm still trying to gradually work it up to 4.5Ghz.

You should go way higher than that, because after all it is a Sandy Bridge K chip, so it is extremely easy to overclock IMO.
Need a doctor??

Higher than the 4.2GHz or higher than 4.5GHz?
I'm definitely going to go to 4.5GHz at least. I've just been inching along.

Right now I'm testing stability at 4.4GHz and my temps are still sticking around 59/60/61/59. CPU-Z is detecting vcore of 1.284v (with droop.)

If I can get higher without going too far above 1.3v (I think 1.32 without droop is the most i'm willing to risk...) and my temps stay under 69, I'll probably push it past 4.5GHz as far as I can.

Someone correct me if I'm wrong: the i5-2500K "danger zone" is at 72.6C and 1.35v, right?

can you provide a link to this magic number of 73C please?
since Thermal throttling doesn't take place til 98C, your number 25C cooler seems a little low.

The Tcase of 72.6C. Or am I misunderstanding what Tcase is?
