I've managed to OC the cpu and the ram as well. Look at the screenies:

But I'm running very stable now at 4.2ghz and ram at 900mhz 4-4-3-4-1T

I can also tighten the timings to 940mhz at 4-3-3-3-1T (3-1-3-6-20 tRRD-tRC-tWR-tWTR-tRFC) or 1150mhz 4-3-3-3-2T but that only gives me extra 200mb/s read speed (from 10050 to 10250) and 1ns better latency.



*Update - I've also OCed my gpu to 666/2100 but can't go any further even though under load my gpu temp is not exceeding 55C... Did anybody ever play with pciex16_1 (2,3) frequencies?
