on a 920,r2e

if i can run 2000mhz CL8 fine with no errors at qpi 1.48( set 1.53750),dram 1.65v,bclk 200 and also tested the xmp profile also
which was 1.6v for qpi set 143 something for bclk
all dram voltage at 1.65v
pumped dram to 1.67 also no luck.

is there other settings for a latency other than dram voltage??
