what is the optimum voltage for SA and VDDQ?
at 4000 mgz, 4x8 SR
am now stable on SA 1.30 and VDDQ 1.26
but board automatically sets SA 1.35 and VDDQ 1.20
overclocked up to 4000mhz all ok, but at 4100 and 4200 freezes when entering the bios, it turns out only 1 out of 5 or so enter, at the same time in windows runs without problems, and the test TestMem5 does not freezes
what could be the problem?
