These are great memory chips! Have this exact set in my system, and have run at 8-8-8-20 without issue. NewEgg has them now for $49.99 with free shipping! Crazy good deal to be honest.
I got 12Gigs in my rig of the G.SKILL Trident+ Turbulence II Series 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 2000 (PC3 16000) Desktop Memory Model F3-16000CL9T-6GBTDD. they run great and have had them for about 6 months now and no problems so far with them. GSkill makes good reliable memory IMHO.
