OC 3770K on GA-Z77-DS3H

[enginerd]

Anyone else OCing a 3770K on a GA-Z77-DS3H? Can you get a stable system that can score over 15000? I can get several different configs that can do 15000+, but not stable. Best stable config I could get was 14867. Not being able to set Vcore really seems to limit things.

What settings are you using given the limitations of the motherboard. I set CPU frequency to 44 and all the Turbo settings to 44 which is giving me mid 13,000's but with the i5-3570K CPU.

i tried so many dozens of configurations. my stable config is with CPU at 42, but turbo set to 45, 45, 43, 43 (for 1, 2, 3, 4 cores, respectively). I could get a single core up to 48 or even 3-4 cores to 44, but that actually lowered GB scores (throttling occurring). I also tried with all power saving off, but keep it on for normal use. I'm using an H100 cooler so temperature in HWmonitor stayed below 55 in Prime95. I also set the max wattage to 300 and amps to 200. Couldn't do much on memory so left it at 1600. I played with goosing the PCI clock and could get it to 102, but I think memory went unstable. i tired cranking up DRAM voltage to 1.65 and loosening timings and couldn't really get overclocks beyond 1800.

i just did 16352 (64-bit) with my i73770k and z77-ds3h over clocked at 4.3 (and stable) (just changed in the 3d bios from 3,5-->4.3)
