[SOLVED] Dual Channel RAM

[fedekerplunk]

ok so here's the point, I've got a M5A78L-M LX3 MOBO with 2 DDR3 slots, and I've installed two (1333 MHZ, 2GB each one)--->> KVR13N9S6/2 Kingston's RAMs, so I enter to CPU-Z to check the channel modules and they're working on single each one, have got to be identical part numbers? (besides from freq. and lat alright)

Thanx!

You mean ranks? If so, thats different. Single / dual rank is to do with the IC chip arrangement on the memory PCB.

Dual channel should be mentioned under the memory tab -> channels.

I mean "part number", as you can see the #1 is 99U5595-002,A00LF and #2 is 9905595-006.A00LF, so both are KVR13N9S6/2 (same freq, same lat, same model) but different part number, so it's gotta be that, the below image confirms that's in single channel

Could be incompatibilities between the two ram. Does all 4GB show up as usable in Windows?

In the bios;
Set dram voltage to 1.65v.
And try set command rate to 2T - this option is under memory timings, bottom of list.
