maybe that's working with 2 x 1gb sticks but not with my 2x 2gb ocz hpc reaper 1066 and e8400e0, using 445 cpu fsb and 1068 mhz on ram, my pc posts on the 333 latch 2.4b untill 1.26v mch which is not enough to be stable . When i go above 1.26v the computer just loops.
The memory controler on this board when using 2 x 2gb is just 2 buggy on the 333 latch using bios f8

If you looked at my sig, I have 2x2gb Gskill PI PC28800's. Hoss, also had 2x2gb OCZ 1066 RAM and had the same exact issue. Using less then 1.34MCH fixed our problem, bios F7/F8 and F9B, revision 1.1 board. We also both have Q9650's, so if your dual core chip causes it to not be able to boot over 1.26MCh then I am not sure what you can do, sorry

I have countless sets of ram for this mobo.most i can get is 1100mhz@ 5 5 5 15 - i am looking for the ultimate 2 gig set that will further embellish this great motherboard, a set that will hit 1200+ and also achieve tight timings at high speeds.
any suggestions would be great,still looking,i should be able to get another set if i sell my adata 8500 & crucial tracers 8500 - think i will keep my g.skill but would love a great 2 gig set.thanks in advance for any help provided

i don't think is the cpu, cause its a great one, i think it's the motherboard which is rev. 1.0 and that's why i guess i can go only as high as 1.26v on the 333 latch. Youre ram is better than mine and maybe they are more stable with less mch volts.
Anyway some problems still are with this motherboard , why making available mch volts up to 1.6+ when u can use a max of 1.34 or 1.26 in my case. There must be some issues causing this loops after passing a certain mch lvl .

The strap is broken. About 5 to 10 pages back there was some discussion about this. Jor thinks that Gigabyte will never fix it because it would just cause a different strap to be broken. In the beginning I had the same issue and you do but it was 434FSB instead of 435. You can boot at 434 and then use ET6 to adjust the FSB if you wish, it works that way.

I have notice that sometimes when the gap between CPU Term and MCH Core are bigger the ~0,15v I can´t boot and if I bring down the gap it´s okey.

Strange thing, anyone have any comment on that one.
