x58, Should I use 3x4GB or 4x4GB

post #1 of 5
Thread Starter 
Hey OCN,

I'm upgrading my ram to see if I can squeeze a little more out of this 960 (I believe 6x2GB is limiting my OC)

Triple channel kits are either old, expensive or hard to find so...

I bought 2 G.Skill Sniper 2x4GB (DDR3-1866 CL9) Kits.

I only need to use 3x to use all 3 channels, 12-16GB will make no difference to me.

Will having more ram on 1 channel will affect my performance/Stability at all?

Thanks in advance!

If you have unbalanced capacities on channels you will have to interleave between them which would likely decrease your available bandwidth as you can't pull large pools of data equally through all three. Given that a triple channel setup gives you an abundance of bandwidth to begin with, the difference shouldn't be huge, but you may notice a slight percentage of loss.

Also keep in mind you don't need a specific triple channel kit, you can buy similarly spec'd/branded DRAM in single sticks to approach your capacity or performance goals.

This.


I also recommend using only 3 x sticks of ram. 12GB is enough.

According to you motherboard manual, you can do it with 4 slots but I would use only three.

Four DIMMs will still be triple channel for everything that still fits in the first 12GiB.

The channel with two DIMMs might need to be run at slightly looser timings (T2 and maybe a higher tRFC), but otherwise should do nothing to hurt performance. A modest OC hit on the uncore and memory is a possibility however.

If you have use for more than 12GiB of ram, use all four DIMMs.

Thanks a lot guys, great info.

1 stick was actually DOA, so for now I'm down to 2 sticks

I think I'll just find my best OC with 3 sticks, then pop in the 4th and see if I can keep similar performance/settings.

Cheers
