Anyone running Maximus VI Formula here with Samsungs ICs at 2800C10 ? can't seem to be able to get these stable. 2600C8 PSC and 2800C11 Hynix no issues for my testing.. just can't get the 2666C10 to work properly at 2800C10... prolly overlooking something...
New test bios for XPOWER users E11 download here: (flash at own risk) I haven't had the chance to test it out properly...
EDIT:
1) Seems at 2666MHz there's a good speed improvement. With my Corsair 2666C10, gaining another 2-3secs over 11A test bios with alike timings in the bios in SuperPi32M, so MSI is on the right track.
2) CORSAIR 2800C11 kit remains problematic to boot on this board, no matter the timings/voltages. When it worked it got identical scores as the 11A bios... so at first glance no real improvement there
