Looks like max 1:1 @ 1T is 285 x 9, I can go up higher to 290 x 9 1:1 @ 2T. Trying to find Prime95 stability though and checking benches to see what is actually faster. I can go 290 x 9 and drop the memory with the divider seems the chipset is the limitation running 1:1 over 285 just crashes or reboots on me.
