Sorry when I say 1:1 with a bit of overspill i mean 4:5. 5:5 = 1:1 so 4:5 = 1:1 with a bit of overspill. If that makes sense?
Unless of course you're running G.Skill HZ's.
All my tests were run with 1.9V VDIMM regardless of timings. 1.9 in BIOS is about 1.94 actual.
3-3-3-5 is not tight as in the true meaning of the word "tight" eg.
Go as far as the bios can take you with this DDR2 option for timings.
Can your board to 3-2-2-4-2 ?
how do you know its 1.94v ? use a DMM ?
