BUT NO DUAL CHANNEL in my board, cant boot when my memory are in Dual Channel :(
You timings are very aggressive. I would back off on the twr and related timings. Also try tras at 6. Back off to 230mhz to test.Quote:

Try swapping the sticks in the orange slots to find a combination that will boot. The 2 slots have different requirements and this will usually work if your board is fussy.
Let us know how you do.
Still tweaking but here is what I go at the moment

Should i really lower the timings, i have just used settings from the WPCREDIT threadQuote:

No matter what slot i use, it bugs anyways
When i try give more then 3.2 volts, it gets very unstabel, dont know why
M8, I just had the same probs with the shipping bios of a SLI-DR, more than 3.2 = instant memtest errors, just flashed with 3-10 bios and all was fine, currently burning vx @ 3,4 -500mhz DDR :D (hope it helps)... sorry for the offtopic, but thought it might help, will report back on topic once i figure out stable timings for this mem / moboQuote:

it stabilizes voltages, and also, dont froget that dfi boards love to have voltage fluxuations too,
keep that in mind for memtest errors
