DDR2 Full Specs

[necron66]

These are somewhat older G.Skill modules as they're simply Crucial Ballistix with a facelift.

As the ICs say '-25F' you have Micron D9Gxx binned at 400MHz (DDR2-800). This could in fact be either D9GMH or D9GKX.
There's no way of telling which one it is, but it doesn't really matter.

Thanks r00n, what does binned at 400MHz mean? I guess it's DDR2 800 thats clock to 1066MHz? That would explain why I have a hard time overclocking it at all? It runs fine 4-4-4-8 @ 1000MHz, but always memtest errors if I raise the MHz ~1160 on the next divider.

-E- the chips are 10.0x10.0mm if that helps.
