Some issues dont make any sense.

As I said I got 3Ghz/2.4GhzNB stable with the ram at 5:3. With 2:1 it would error or even reboot. I tried lots of Vdimm untill I noticed my RAM was 70degrees Ive no clue how or why, my Vdimm wasnt that high. I figured the reboots came from too hot RAM, so I lowered Vdimm and instead of reboots I got errors. However, errors never went away. At some point I wanted to be sure my setup, excluding RAM, was still stable... It wasnt while I only tweaked RAM after the last stability check

Spend till 03:00 in the night figuring it all out and finally I just set all ACC to +4 and set Vdimm at 2.11V and the RAM still at 2:1. That was stable again. Now this morning I decided, with very loose timings, the RAM at 2:1 and it already runs for a very long time... Ive no idea what's wrong, but I think Vdimm might be incorrect with this motherboard? I cant give a conclusion why my RAM would run 70 degrees before with like 2.2Vdimm and it's only 30 degrees under full load with 2.1Vdimm.

Also I found some interesting about tRC, namely if it's loser you need a lot less Vdimm while it doesnt really kill the performance.

Anyway, I noted my all my settings this time so if I land in a labyrinth like last night again Ive a solid base to get back to. Now lets hope I wont have to mess a lot with timings anymore and get my 4-4-4 without too much Vdimm
Memory support is not as good as on 790FX on 790GX. The AsRock790GX overvolts the memory ~0.1V maybe asus does the same. Also had alot of trouble with cheap kit's whom required an too high tRC that K10 can offer.
KTE infestigated memory on 790GX abit more here.
