Hi its my first post. I m from kefalonia Greece. I just had an ABIT AB9 and i can't boot with OCZ PC2-6400 EL DDR2 1GB (2X512MB) GOLD EDITION GX XTC DUAL CHANNEL KIT that im trying to use,as i have C1 error on motherboard. The same is if i put only the one ram on. I used a KINGSTON SO-DIMM DDR2 512MB 533MHz that i borrowed and it works, it did boot and i got in to BIOS settings. The motherboards' BIOS update is the latest 1.4. I 've given back the OCZ and i will order the CORSAIR XMS2 DDR2 PC6400 (800MHZ) DUAL CHANNEL KIT 1GB (2X512MB). I hope it is a compatibility problem between ABIT AB9 and OCZ 800MHZ RAM and CORSAIR wil be ok. Except if ABIT AB9 doesn't match with 800MHZ RAM in general although is being advirtised like it supports them.
I read a lot of forums and the most of people have problems with OCZ. Some, not very many,using other RAM like CORSAIR are sutisfied. Does anyone have a clear knowledge of this mater above or if ABIT will give another update to clear this problem?
The CPU is Core 2 Duo E6600
That's a common problem with your particular RAM, it affects many motherboards, and OCZ fans claim its the fault of all those boards rather than the one brand of modules.
It's not really a compatibility problem, it's a faulty RAM problem, they screwed up SPD values. But you should have been able to fix it easily, simply by booting up with that other RAM and entering BIOS, then raising the memory voltage, saving the setting, rebooting, shutting down, and installing the OCZ RAM.
As for the other RAM that you said worked, well, SO-DIMM's are those little laptop modules, they won't fit your board.
