2x2Gb + 2x1Gb = 6Gb Dual Channel?

Post by DJ Tucker » Tue Jun 11, 2013 12:06 pm

I have (as you can see in my sig) 2x2Gb's of OCZ Nvidia SLI memory @ 800Mhz. I have found another 2x1Gb set for real cheap as new for £15 compaired to £60 for the 2x2Gb set. so can i run in dual channel?

Yeah, you'll just need to fill up all four memory slots and you'll still have dual channel performance.

It sounds like both kits are 800MHz, but keep an eye on timings. Usually when you mix and match kits you need to run the timings of the least aggressive kit. So if once kit is 9-9-9-28 1T and the other is 10-10-10-30 2T you'll have to run both at 10-10-10-30 2T to get it 100% stable.

NVIDIA nForce 650i SLI motherboard is fairly decent when it comes to the memory controller, so it shouldn't be a big deal.
