2500k OC Frustration

[Charlie98]

Are you messing with your BCLK settings at all? When I first started OC'ing my 2500K I bumped up the BCLK to 103 (I think) and it became unstable as hell. I have it back down to 100.3 and it's uber stable.

FWIW, I stopped my OC efforts at 41x, anything over that was either unstable or pushed the temps into the high 80's or low 90's. I don't think my GB board is a big overclocker, or I have a hot chip (or both.)

With Z68XP-UD3 and 2500k, the best I could manage, with 1.350v, was 4.4 GHz with level 4 LLC.

i have a 2500k, and an asus p8z68pro gen 3, is there an overclock guide?

There are tons of guides. You could even read guides based on the old P67 chipset and find useful information. Here's one I found the other day -- for an ASRock board. All you need to do is identify all the relevant BIOS options for the P8Z68.

I have a P8Z68-V Pro [pre-"Gen-3"].

A year ago, communing with some forum-members per Z68 Sandy Bridge over-clocking, I came away with an impression reinforced by posts at other sites and forums: The Gigabyte board equivalents seem somehow short of other makes.

Gigabyte otherwise makes "good mobos" and I have a few. Maybe they're just having a "bad patch."

And not knowing anything about the Giga-Z68's firsthand, I can only say my -v Pro board is stable for i7-2600K at 4.6 with LLC "High" (50%), highest-load (Prime95) (lowest) VCORE is 1.312V and idle (@ 4.6) is 1.34+ to 1.35V. The highest VID reached is 1.375V.
