I talked to AlterBridge86 about the optimal settings for this memory, here is what he reccomended:
Trc: 7
Trfc: 14
Twr: 2
Twtr: 2
Trwt: 3
Tref: 3684
Twcl: 1
Max Async Latency: 8ns
Read Preamble: 5ns
Dynamic Idle Cycle Counter: Enable
When it starts to become unstable, play with drive strength in this order:
8/3, 8/2, 8/1, 7/3, Etc.
Any other inputs or opinions?
EDIT: BTW, thanks a ton for the help AB86!

Micutzu has the numbers I listed above, with the following changes:
TRC 7 -> 9
TRWT 3 -> 4
TREF 3684 -> 1032
ASYNC 8 -> 9
Read Preamble 5 - > 6.5
Dynamic Idle Cycle Counter Enable -> Disable

My settings are on the safe side, allowing more stability and a bit higher clocks. Some of them may be tightened for more performance, i was testing with the older revision of UCCC and that was tougher to overclock than these new ones.
Lower tREF means the refresh of the memory cells is done more often, to make sure the data is preserved even at higher clocks, but giving a little performance hit at the same time. DICC Disabled specifies that only the value set in the ICL field will be used, and the Idle Cycle Limit will not be adjusted dinamically ... this also improves the stability at the cost of some performance.

I'm trying your settings with that bios and motherboard revision and I can't even get 275 stable... what should I play with?

Bump, don't know what to try!

have you run through the process to test your max HTT before trying to max your memory? It may not be your memory that is crapping out at 275, especially if you're running 1:1.
atleast that's how I understand it...
