MY i7 2600k... requires too much vcore. - Page 2

Thanks for the link, I will definitely look into it this week.

Is 1.320V the voltage you are seeing in CPU-Z while the CPU is under full load?

 

Or, is 1.320V what you entered into the BIOS?

That is really high for a 2600k. Most of them will do close to 4ghz on stock vcore. Also a P67 board will have no issue or impact on a modest overclock.

My 2600k will do 4.5ghz at 1.23 vcore with HT on. I've seen few that are lower but also not too many that are a lot higher.

For 4ghz, 1.25-1.26 should be feasible.

I left it at 1.250 and it ran prime 95 stable for about 2 hours before bsoding. I then went into the settings and changed it to auto instead of fixed voltage and now it runs prime 95 without BSODing.
post #15 of 35
What other voltages did you play with? I'd suggest locking the BLCK at 100, PLL at 1.8 and RAM at 1.5 (set the ram manually to the recommended settings for it's kit). This way you can ensure that other factors are eliminated. Also what temps are you hitting? Overheating will cause a BSOD as well.

I just ran it right now, and monitoed cpu-z. The vcore was 1.144 at 100% load, temps were in the 48-50. Then I got a BSOD after 5 minutes,

I tried 1.20, 1.220, and 1.250 which was the most stable.

Obviously because of Vdroop.

Set Load Line Calibration to 50% or 75% (High or Very High).

I set the LLC to level 3, I'm guesingg thats about 50% for so, so far 2 hours of prime 95 stable on 1.20 v core.
post #20 of 35

Which is a huge improvement, because it would bsod within 5 minutes at 1.20v. I never had vdrooping issues with the 2500k, Is this a common thing? CPUZ says it's using 1.168 at 4.0ghz 100% load, so I'm guessing I got a pretty good chip?
