Yes it can work but the thing is for triple channel you need sets of 3 modules and for dual channel you need sets of 2 !! So using a triple channel kit you will either use only 2 of the 3 dimms to remain in dual channel or if you use all 3 Dimms your system will be running in single channel mode since you can not use dual channel mode with an odd number of modules !! (unless using 2 sets of 3 which would then give you 6 modules so you could use all 6 in dual channel mode (assuming your MOBO has 6 slots !)
Hi newcomer and welcome to the Tom's hardware forum.
Basically a tri-channel RAM are 3 single channel stick paired for run in tri-channel configuration with a mobo and CPU that support that configuration.
Now, with the little above information the tri-channel kit should works without problems in dual-channel plus single channel configuration, the question is. Why do u want buy a tri-channel kit for run it in dual channel plus single channel?
