I've been running 2X2GB F3-12800CL7D-4GBRH Ripjaws with my 1055T at 1642 7-7-7-20-27 1T 90ms 5 for most others (308 with 3/8 mem divider, since the 1600 divider is problematic) completely stable, CPU@4004 and IMC @ around 2800 IIRC (at work ATM).

I bought a set of 2X4GB F3-12800CL7D-8GBRH Ripjaws, but they won't post at that speed. Even relaxing timings to 9-9-9 will post but not boot windows.

I'll take another run at it tonight, but trying to decide if I need to RMA (and eat shipping) or if it is a limit of the mobo, ram, or IMC. There is a thread on these sticks in extreme bandwidth where chew* has decent results, but with a CHIV formula. I may try the GSKILL forum as well, but I know they'll whine about weak AMD IMC's.

Will also try upping IMC volts a tad when I get home.
I don't think this board is going to run this particular set to well, or any 790 board for that matter.

Any non 2.1 giga 890 board will have issues as well.

Boards needed a complete hardware rev to support "newer modules"
