Ddr3 0

[gypsyhg]

no dual channel, half ram disappears depending on slots used, bios recognized all ram, windows does not, ram reads ddr3 0, computer still functions.

Any suggestions?

Maybe you have a 32 bit system and only detects 3.25 Gb of 4 Gb max.
Or maybe you buyed the incorrect DDR3 for your motherboard.

Good Luck!
