About skews, i believe that its good to use them above 1800... Delay/Advance, depends on m/b, for example Evo provides more stability with Advance... I dont know yet about RE, i'll post once i'll get her running Try playing only with skews, first advance and then delay, if you have the dimms on A2/B2 slots, tune only CLK's A2/B2..
thanks .... seems D9JNM of mine like advance skews

some other info (2x1GB CL7 + 45nm dual core):

vNB scaling on 5:8:

500FSB/5:8/800mhz/tRD8/CTmod = 1.25V vNB
563FSB/5:8/900mhz/tRD8/CTmod = 1.48V vNB full Blend/Custom FFT stable etc
600FSB/5:8/960mhz/tRD8/CTmod = ~ 1.63V vNB 2Hour+ Blend stable (not tested further)

563-600FSB/5:8...vTT scaling = ~ 0.25-0.3V below vNB, and NBGTL Auto

to avoid 32M errors / other instability set PLL+SB1.5V @ 0.04v (min) < vNB, or = vNB, or > vNB

NB+A/B DDRrefs not needed at 563/5:8, but find some windows startup problems nearer 600FSB without all set @ +12.5mv (same @ 500FSB / 1:2)

Auto skews pretty good imho.. (0403 BIOS). the only DRAM skews i found useful previously were CTL A2 Del 100, CTL B2 Del 75, mainly used with Transcend samsung. also back on Auto for CPU/NB skews.

i ran HCF0 and D9JNL but now on GTR - difference is big + very easy to clock with stability. JNL was a lot better than samsung, but timings and voltage response still too limiting for the board.


600x7.5 / 5:8 / CL7 / tRD8 / CT mod (13.xGB/s Read / 39.x ns with auto subs (tRFC88)

tested: 2Hour+ Blend / dual 32M / 32M

thanks must try your tips as i can't seem to get my Gskill D9JNM based PC3-12800HZ past 950mhz right now heh

Hope this helps
