Vcore hungry 2500k has me a bit concerned! - Page 3

post #21 of 23
I know my VCore was more in the ballpark of 1.37 when I hit 4.5, you may want to try bumping the VCore. Also, you may want to check out this thread...http://www.overclock.net/general-pro...hen-ocing.html... to see what the BSOD code you are getting is for. Hope this helps!

EDIT: Also, I've never had a GPU cause my system to BSOD. Usually if it is a GPU issue the system freezes (I believe), it doesn't generally BSOD. Anyhow, hope this is helpful.

Thank you! +rep

My parents like to keep the house at about 80F during the summer to cut down on the electricity bill.

Unless they change their minds, it looks like I'll have to save my settings for a summer overclock and a winter overclock.

I do not mean to hijack your thread in any way OP, but I'd like to say that I'm experiencing the same sort of issue (as we speak!) I think/thought I got a bad batch 2500k, because I had it at 4.5GHz @ 1.33v for the past 3 weeks no problems, but over the past 3 days I've gotten two BSOD's, and it looks like it's from a hardware failure.

I personally suspect the video card is to blame because it's a used one from a friend that already has snow/artifacting problems in games which I knew before I installed it, but I don't have another card to test my system with atm. In Prime95, when I tested it today, kept giving me an error "rounding 0.5 expected less than 0.4" within the first 10 minutes. From googling, it can be found that, that means your CPU needs more vcore. I bumped it all the way up to 1.35 and it still kept throwing up that error.

But like I said, in the past 2 weeks I never experienced any real world stability issues. ANYWAY, from what I've read, very few members need 1.33v+ to achieve 4.5GHz. The reason why I'm afraid to put any more vcore in is because, me being a noob (my first build) I can't get the thermal paste on right to save my life! I tried 3 times, better results than before by about 10C, but still not what I was looking for. At 4.5GHz and 1.33v ambient room temp about 80F, my CPU maxes out at 80C on some cores during Prime95, but stays at about 73-79C most of the time. In real world use though, I haven't seen it get higher than 68-72C.

I have it clocked down right now to 4.4GHz @ 1.32v, Prime95 has been running for half an hour with no errors or BSOD's. We'll see how it goes... But as it stands right now it looks promising.
Hmm, if your still running the stock cooler then I would spend the cash and get maybe a H50 or a Noctua or something. That, or put your thermal paste on in a "Cross" shape on your CPU then let your cooler even it out, or just put a thin layer across the chip and seat your cooler.

As for overclocking your chip, the best advice I can give you is what I did in my BIOs to get my chip to run at 4.5 at 1.29..

-Internal CPU PLL Overvoltage = Enabled
-Real-Time Ratio Changes in OS = Enabled
-Intel Turbo Boost Tech. = Disabled
-CPU Enhancement Halt (C1E) = Disabled
-C3/C6 State Support = Disabled
-CPU Thermal Monitor = Disabled
-CPU EIST Function = Disabled
-Multi-Steps Load-Line = Level 6

-Vcore manually set at 1.295
-Downclocked 2133 RAM to 1866
-Manually set RAM voltage to 1.505 (Regularly at 1.500)

Before I did all this I had to run AT LEAST 1.43 Vcore to get my chip to run at 4.5Ghz, after doing all these tweaks, I got a little over 50% drop in my Vcore, making my temps a lot better, and a peace of mind for myself, and my chip.

EDIT - I see your not using a Gigabyte board, the settings may be listed as something different for your mobo, so if you can't find those settings in your BIOs, don't flip out xD
