I didn't have much time so far, so I tried a couple of different settings with 1M to get a slight idea what is possible and what is not.
I will do more testing with 32m over the weekend, here is what I have so far:

Edit: All tests were done with 2,24 V Vdimm. I know I am a jerk Will try with less voltage tonight. I have a strong feeling it is the board limiting me and not the RAM, so the settings below will most likely run with less Vdimm too.
Fr3ak,
which motherboard are you using?
If you want to go above 900 you have to give volts to nortbridge, with these DDR3 RAM the memory controller integrated into northbridge is very stressed.
