Hamid,
this is the issu we have been discussing for what seems like forever.
if you have the DS3 you can't run the D9GKX ram over 950 stable. SOME and i mean that,, SOME have been able to, but 99% of those cant run that high.
if its the D9GMH then i understand it can run a little higher.
but in general your are up a creek at 1000mhz it just will not go any higher no matter what you do.
SUPPOSEDLY gigabyte has a fix for this, and this is what the F8 beta bios is supposed to fix,, but we have to wait for ken to free up some time to share it with us.
Martian,
with DDR2 they run insanely low subtimings. and there isnt alot you can do to change that, as you said on auto they are pretty lose, but even to go tighter it doesnt improve speed at all.
ther eis only 1 or 2 subtimings that can actually improve overclocking and its not like its a huge difference.
i think coolaler, freecableguy and a few others did some testing where they talked about adjusting certain subtimings, but good lord that thread is probably long gone unless someone has it in their favorites.
in general the main 4 timings with DDR II are the key. where as with DDR1 and TCCD you really had to fool around with alot of the timings to really make the ram scream. know what i mean.
but, yes i agree they are pretty lose but not much will improve by going tighter.
