Msi neo & 3700 clawhammer maddness

Question

Before i go into a long tirate, can anyone tell me if the 3700 claw requires ecc memory, memory faster than 3200 (corsair 3200 tccd 428) 2.5-3-3-11.Why when i oc to 2700 my bandwith drops from 3500 to 2700. Stability is gone running a bench yet mem test is stable, running any bench results in bsod. T1 or t2 means chit, timings has no endearing qualities,  . I can lower the muti and clock the fsb to 240 memtest stable, boot into windows and corruption all over  no benching allowed.Or up the multi and set the fsb to 220 and still the same  . memtest stable yet corruption all over. Psu 485 noisetaker 33 amps 12v, Msi neo, Corsair 3200c2 xms c2 tccd 428.  Last but not least my 6800 gt wil no longer overclock to 425/1160 and using the mbm5 prog all the rails are rock solid no variation at all.  Is this the mem controller da cheating bitch     (ohh idle is 32c load 45c & no sata just plain old ide)

Answer 1

You're probably right it's the ram controller, especially if you're running 4 banks which means you're up to the supported limit @ stock speeds.
If you want to go into unsupported territory you want to up the ram voltage a bit and maybe drop the latency a notch (down to CAS 3.0) and I wouldn't want to oc the ram so yes faster would be better but it's not required and ecc is certainly not required.
