ok finally today i have enough of our lab and i personally got a DS3 with F3 bios.
not matter what i set in the bios ctrl+f1 CL4-4-4-12 with FSB 200 and DDR2 800, after i boot into windows it show me CL3. that is very weird. anyways, that is using F2-6400CL4D-2GBPK @ +.2v in bios
then i got a set of F2-6400PHU2-2GBZX and it will not boot up.
that is right, it is not boot up at 2.0v. then i using another ram set as 2.3v 1.8v+.5v and it boot into windows with CL3-4-4-12 again. even with my mannally set to CL4-4-4-12 in bios it still show CL3-4-4-12 in CPUz 1.35
currectly i have no idea which parts is causeing the problem. we are contacting gigabyte to solve it. I am going to test on Asus 965 again
Now i am sure that
F2-6400CL4D-2GBPK is boot up at CL3, even with mannally set to CL4 it changes back to CL3
F2-6400PHU2-2GBNR no problem
F2-6400PHU2-2GBZX and F2-6400PHU2-2GBNS are not working right.
