Excellent article. I'm still wondering if the memory can break that magic 1Ghz speed though....I think it can since they are rated for 1Ghz. Oh yea, what's F@H like on them? Do you have an idea?
Intel Core i5-3570K @ 4.2Ghz @ 1.16V (CPU-Z + LinX)
Gigabyte Z77X-UD5H F14 BIOS
ASUS GTX 460 768MB @ 800/1950
Kingston HyperX DDR3 8GB @ DDR-1333
Corsair AX750
Crucial M4 128GB
Western Digital Black 1TB
Cooler Master Hyper 212+ EVO
BenQ E2420HD

Much over 1000MHz they get unstable and at 1015MHz they were locking up... They need more voltage as at 800MHz (default), I'm sure ATI lowered the voltages. Also the card is by no means memory limited.
