[SOLVED] Dual Channel query

[robbiecas9]

Currently I'm using Kingston fury 8GB ddr3 1866MHZ. I'm thinking of purchasing a 4GB DDR3 1866 of the same brand/class/frequency. ie. kingston fury.

Will i be able to run in dual channel? or do i have to get the same size (8gb) stick for it to run in dual channel?

8GB ddr3 1866mhz
4GB ddr3 1866mhz

Can i run the above?

If they run together well because mixing isn't guaranteed unless in a set, then they'll run in flex mode (not full dual channel), where half of the 8GB stick in dual with the remaining 4GB single channel.

Getting the same capacity is better.
