DDR3 2133 (O.C.) / 1800 (O.C.) / 1600 (O.C.) / 1333 / 1066.
I also set the Ram clock to ~1700
Most PSC ICs hate lower tRCD.
I'd recommend going for the RMA because you're obviously not getting the performance promised for your money.
This one may be more off-topic, but here goes. Ignore G.Skill, drop some F-bombs at them if you have to, IF they tell you any BS such as "AMD requires higher timings for stability" or "this set of memory is not rated for the AM3 socket". It's just scam, RAM is RAM and should work on all platforms where the speed is supported, and most likely they'll tell you this at least once in the process of RMA-ing and make you want to buy something such as G.Skill Flares next time which costs more and doesn't perform any better. This is the only issue I've found with G.Skill tech support, otherwise they're pretty awesome. They need to realize that us AMD users need love too.
EDIT: ALSO, i was at first going to get GEIL ram, but then y'all told me no no get G Skill. Now y'all say service sucks.
Just saying, they're not as friendly to AMD users as they are to Intel users. So if they try telling you that and attempt denying you RMA, don't fall for it. You should be getting the performance you paid for.

I'd say Newegg as well though to keep it simple
