Using this post as a guide I'm 1800 stable @ 9-9-9-26 2T.

The CPU can run at 3600 easy. 1.325 v auto VTT and PLL.

Just going through the incremental testing at lower timings now, it's amazing just lowering the tRP by one causes memtest to fail. I rasie NB and retest ok..try the tRCD -1 next and boom memtest fails. It's going to take alot of tweaking I think.
