Whats best, 4 x 4 or 2 x 8?

Whats best, 4 x 4Gb sticks or 2 x 8Gb for DDR4 2400?

4x4 if its x99 or 2x8 if its z170.

 

[justintime2001]

Thanks los, it is X99.

Does it make a big difference either way?

Yes, quad channel gives 2x more memory bandwidth than dual channel on the X99 platform (assuming same memory frequency and timings but it can get more complicated than that).

 

[PWR_USR]

ahh of course, forgot about the quad channel part

You're right but I'm not actually convinced you'd notice the difference between quad channel and dual channel for gaming etc.

Does this only apply to the X99 platform?

4 x 4 for X99

X99, X79, are quad channel. X58 is Tri-Channel. Everything else (unless going back to about 2001) is dual channel.

In practice, you probably won't notice the difference with quad vs dual channel, unless you are doing something specifically memory bandwidth limited.

I have an 8 core Xeon E5 with 2x16gb DIMMs in dual channel mode and it performs perfectly well. I would score higher in say, Winrar benchmark with quad channel.

Ok, thanks.

can you run one stick of ddr4 ram or does it have to be pairs

cheers
