thanks VIVID, i'll try another cpus in weekend, as we see we are totaly cpu limited, single channel,dual channel, cl8 with 10 or 11 tRCD all are very close, it means with a good IMC we can do +3000 cl8 easy. hope to find it one day

last night i tried +1.80VTT on the cpu but doesn't help me 1MHz same for Vdimm 1.75 and 2.50 gave me same result.
