I often find 2x +2 works great in most situations as well, especially when pushing high overclocks

That's my find too!

I know about the uncore and mem multi relationship, I always just set it to 2x that of the mem multi, however, when using the 6x mem multi like I am in those screens above, I have to set uncore to 13x, if you try using 12x the system refuses to POST..

Do you guys reckon if I give it more Vtt I might be able to get my Dominators running at 1680MHz?

What tips can you guys give me for overclocking RAM?

I have tried running the RAM at 1680MHz CAS9 with the processor at 4.4GHz, but it got to about 15 passes of LinX and then stopped due to errors..

I forgot to mention what voltages I was using for those screens above.

Vcore 1.400v (BIOS), Vtt 1.255v, VDimm 1.500v, CPU PLL 1.300v (my system becomes unstable if this is left at stock 1.800v, but if I set it to 1.3v everything seems fine!) IOH core 1.140v, QPI PLL 1.140v.

Hopefully more Vtt will let me run at 1680MHz, I mean, it's only an 80MHz bump in frequency!!
