I just got a message off msi support and they sent me some unreleased bios that seem to have sorted my ram issues.
On stock bios I could run 2133mhz but it was a bit iffy sometimes posting and then after changing to latest bios I couldn't even boot at anything other than 1600mhz on auto. Even with 1.65v in it wouldn't boot at anything other than 1600mhz.
On the bios I got today from customer support I went straight in for 2133mhz 10,12,12 and it booted straight away.
I haven't got round to tightening timings up yet but hopefully msi have fixed the compatibility issues with the samsung green and I will be able to run at 2133mhz 9,11,11 21.
Still since putting in the amd 7950 card the bios are still running in 640x480 which isn't supported by a lot of screens. I have tried updating motherboard bios and it didn't help and my graphics card is already on latest bios.
It's really annoying having to use a different screen to access my bios and can't seem to find a fix but lots of people are having same problem.
