Hi all,
Bit late to this party, hopefully I've got something useful to add, but really I could do with a bit of assistance.
I purchased the Geil 2Gb pair when they were on special and they're currently sat in my DQ6 / E6600 setup behind me.
Trouble is, I can't get them to run at 800MHz / CAS4.
The BIOS defaults to 667MHz CAS5 (5-5-5-12), as others have said. Actually the machine is rock stable, but you know what its like when you know it should be capable of more.
I've raised the voltage to 1.9 and manually set 4-4-4-12, I'm still rock stable - at 667MHz (x2.5 multiplier).
Unfortunately 800MHz (x3 multi) at 5-5-5-12 is not 100% stable.
I did try running the sticks at 2.2v as discussed here, but it didn't seem to make much difference.
Is there anything else I can try, or have I missed a trick somewhere along the line? I must admit I'm still a bit confused around things like FSB
DR
ratio - currently I'm at 4:5 (or 5:4!). i.e. (333x4) / 5 = 266
Oh, and I'm on the F3 bios - was the first thing I did when powering up the beast.
