FM2 chipset vs RAM speed

[tronath]

I have tested 2 Gigabyte FM2 boards recently with samsung green modules in an attempt to clock them at 2133mhz. I'm currently running them on a Z77 board at 2133mhz without any issue. For some unknown reason, if I set the memory speed above 1600mhz, it will refuse to boot. Boards I tested:

F2A85X-D3H
F2A85X-UP4

I borrowed some 1866mhz RAM from another PC which has an XMP profile which the boards happily accept and will run the RAM at 1866mhz after applying the profile. I did make sure the BIOS was up to date too.

I'm not using the FM2 build now, but has anyone else come across this issue?

My Asus F2A85-V PRO AMD A85X, has issues with geil evo 1866 memory, it wouldnt run it at 1866 no matter what i did. So moved to Geil Corsa Evo 2133mhz and it's fine runs it no probs.
