ASUS P6X58D-E and Corsair DDR3 Dominator Dual Channel

Hi newcomer and welcome to the Tom's hardware forum.

1- Tri channel only works when u have populated A1, B1 and C1 or A2 B2 and C2 slots, in other configuration u only get dual channel.
2- The A3 slot doesn't exist, so, in that case u get a dual channel in the A1 A2 slots plus another dual channel in the B1 B2 slots, or the slots where u install the new kit.
3- Be sure that the RAM have the same specifications that ur current RAM or could it be a problem.

A) If u want the tri channel, u need install the RAM in A1, B1 and C1 slots, ur current configuration A1 A2 only can give u a dual channel even if u install another RAM stick, so, u need change the stick of the A2 slot to the B1 slot and install another one with the same specs that u current RAM in the C1 slot.

B) If u buy two more kits, all ur RAM slot will be populated and in that point u will have two tri-channel set running in ur rig, but BE SURE that are the same specs even if u can the same model that ur current RAM.

^If u install another dual set in the configuration that u say u get a tri-channel with A1 B1 and C1 plus a single channel in A2.

Be sure that are the same specs even the same reference for sure the tri-channel, or u can re-sell the dual channel that u have and buy a tri-channel kit.

Any time, that's why we are here. If u need more help come back to the forum.

Does Corsair have a 3 dimm 12 gig dominator set? I don't want to go down in size, they don't make 3 dimm 8 gig sets that I'm aware of...and probably would get more "performance" out of a 6 gig triple channel than an 8 gig in dual channel. That being said, I want to move up in size, not down.
