I just added 2x512MB of buffalo ram, and it is showing up as single channel under CPU-Z. It's a perectly matched pair so what's wrong? I'm on a MSI Master2-far.

2 Opteron 240's
1 MSI-9130 Master2-far motherboard
1 WDD 120GB HDD (special eddition(8mb cache))
1 Chaintech Geforce5200 FX (128MB)
1 52x24x52x16 (combo drive)</

Nice motherboard.

I assume you have only two dimms. (not three, as you said "Added")

Looking at the manual...

"Memory Population Rules"

Dual Channel:
Dimm 1 & 2 -OR- Dimm 3 & 4 -OR- Dimm 1,2,3 & 4

On that board Dimm's 1&2 are the two closest to the processor.

So your two dimms should be directly next to each other, without an extra slot between them to work in Dual-channel mode. (And not installed into the middle two slots)
