I have a different CPU but may help a little anyway, I was playing around with CPU/NB and RAM for the whole day today. I concluded that overclocking CPU/NB gave "massive" gains. Even if you do run RAM at 1600MHz it does not give such a boost from 1333MHz as CPU/NB does from stock 2000 to 2600/2800MHz.
I'm currently running CPU at 3.5GHz ~1.27V (not much but it's hot here and I mostly do rendering all the time), CPU/NB 2800MHz at I think ~1.25V, RAM running 1333MHz 7-7-7-21 1.65V. I haven't done a lot of stability testing but it's stable rendering for 3 hours now, I'll run stability tests after I finish.
From my experience I see no point in ramping RAM freq. since the IMC on AMD is weak. That's why you see quite a big boost when overclocking the CPU/NB. Try 1333MHz with tight timings (try using 1T command rate, sometimes it can provide 4-5% boost but it's harder to get it stable at 1T) and ramp up CPU/NB as high as you can.
