What speeds are advertised vs what do they run?  What tweaking have you done to try and get them to run faster?

Technically anything over 1333 on AMD is overclocked and it depends on the motherboard if it can handle it. I have some 2133 that won't run over 1333 on a ASUS AM3+ board and that's a good brand.

Hmm...a 12 GB kit on an AMD board?  Methinks it's old Nehalem/Westmere memory carried onto a dual-channel platform.  It probably doesn't have an AMP setting for AMD boards...

[ir_cow]

yeah thats a odd number

[Zig-Zag]

Advertised 1600 cant get them over 1066 advertised timing 9-9-9-24 cant get it over 6-5-5-12 And there a 8 GB and a 4GB kit and there the same in every way.

Running a mixed setup like that is just asking for trouble...and I hope you're not lowering timings thinking it's going to make it clock higher.  9-9-9-24 is MUCH slower than 6-5-5-12 and will definitely restrict your clocks.

Sorry about my first post, that wasn't very helpful...it would appear you're not really up on how memory timings work. The lower they are the faster that specific cycle occurs, I forget if it's milliseconds for each setting or what the unit is but just set them to 1600 and 9-9-9-24 with everything else stock in the system. If they're unable to do that than perhaps remove the lone third stick and try again if they STILL don't work I would then RMA them since they're not able to deliver their advertised speeds.

Ram bios are set to auto underclocked to 3.5 just so it don't bsod

Set whatever you know the spec of manually to stock specs and run some stress tests like Prime95

[ir_cow]

The super long way to find errors is running each set at stock setting (1600 or whatever it is) using memtest86. If they both pass at stock. Put them in together again and run both at stock. Finally if it passes try the speeds you want but know it doesn't always work outside it's specs.
