2 x 4gb DDR3 1333 and 2 x 8gb DDR3 1600 ?

Can I use 2 x 4gb ddr3 1333 and 2 x 8gb ddr3 1600 ? My motherboard supports both 1333/1600 ( b85m d3h a gigabyte )

Yep you can, but it will all run at one speed, probably 1333, but you can set it manually

Actually I threw together a system with a Z97-A and it runs 2x4GB at 1600 and 2x1GB at 1066, so I think there's a chance it'll just run the speeds at whatever jedec spec it can get away with.

screenshots? Basically all systems run the memory all at once speed and timing.

Right now using 4 gb x 2 ddr3 1333 speed.

So I'm planning to add additional 8gb x 2 ddr3 1666

Thats reading the speed off the chips profiles, not the current speed. Try changing the speed in the bios and those won't change.

Then idk, perhaps 1600 is all there is to it. I know that dynamic memory modes are pretty sophisticated but it's better to have the higher speed anyway.

Alright, thanks
