Compatibility between these two DIMMS?

[jackofalltraces]

Hi all!

Long story short: I have an odd number of RAM sticks, all three are the same but I want to add a fourth. Trouble is, these came as two pair, and the fourth disappeared in a move (things were boxed). I found one that I *think* matches, but I'm no memory expert by a far cry. Can anyone tell me if these two will be compatible?

I believe the important part is the HX318C10, and that the FR/8 and BK/16 are simply color and total package size numbers.

Thanks!

if they are ddr4 they gotta be dual channel if they are ddr3 there shouldnt be a problem

Ddr4 doesn't have to be dual channel. There is no difference from ddr3 and 4 as far as mixing ram or number of channels.

Just put them all in and run memtest.

Okay, I should have clarified - all three run fine together, but not as dual channel. I want to add one more to get my dual channel setup back, as I understand that performs better than not dual channel.

These are DDR3. I just wanted to know if the red one will match the specs of the black ones I already have.

Thanks!

like my msi mobo has 4 dimm s 2 are for single channel set up the other two are for dual channel strictly . ddr 4 ..

I meant running all 4 together and running memtest. They are the same specs.

@k19, That has nothing to do with ddr4 but rather just how the mobo is setup. What model?

I think you just misinterpreted the manual. It's not setup differently. Any individual slot can be used and ran in single. All slots can be filled and run in dual. Just 1 and 3 are still dual. Just 2 and 4 are still dual. Just about every mobo manual will recommend dimma2 or the second from the cpu but it doesn't make a difference to channels or performance.

I'm not sure if you were addressing me (no pun intended!), but that IS what I thought - that if I had Dimms 1 and 3, it's dual channel; if I had 1, 2, and 3, that they would all be single channel. I need to go back through the manual.

It was a response to k19 who said there were 2 slots that are single only and 2 slots that are dual only. It's all false like the earlier comment about ddr4 vs 3.

1, 2, 3 would actually be flex mode. 1+3 in dual with 2 in single.
