This feels a bit too much razor's edge to me, and I'd like to have a bit more of a margin. What are the key factors to that? The one that's apparent to me is the Uncore/QPI voltage. I'm at 1.35V currently.

AFAIK most people cannot hit 4000 and thus are limited to less than DDR3-2000, but a bit more than 3200 should be possible on my rig...

I have the P6T Deluxe V2 with 920 D0. If you go back one page in this thread you can see my screenshots at DDR3-2000Mhz 7-8-7-20-1T Uncore 4000.

This was not possible at all without changing B2B setting to 10 or 12. B2B is under your memory timings. Asus defaults this to 0. I would BSOD instantly with LinX or MemTest until I changed B2B to 12. It also allowed me to lower my vQPI and vDimm voltages significantly while still staying 20 runs LinX maxmem stable. Try it out.
