I ran it at 5860mhz on vantage, win 7, rampage. Needed good pouring. Vcore was less than 1.65v. Responded well to input v. Mem 3300mhz+ no problem. Cache iirc was 4850mhz. Pro OC'er binned it before I used it and ran 5.9ghz cb15, again on rampage. Just needs time spent in bios to max. Cbb was 120+.
