My MSI 875P NEO-FIS2R won't accept my BIOS memory timings. During POSTing it reports that the timings are too tight, when I raise the FSB to 250+ and running FSB and RAM in sync. Increasing the vDIMM doesn't seem to make a difference. When setting Performance Mode to slow, things get a little better, but it only works with the By SPD-setting, and PAT is disabled automatically... The original BIOS is CPC-enabled (according to SiSoft Sandra), and I suspect this could be the source of the problem, as my memory sticks are double-sided.
