Fastest RAM: 2x4 GB or 4x2 GB?

post #1 of 8
Thread Starter 
Assuming all other things equal, would four sticks at 2 GB each get faster speeds than two sticks at 4 GB each? If yes, how much? If no, why? I'm looking at 1600 MHz right now, if that means anything.

4 x 2 gig is faster. Memory controller has four places to send the data (two dual channel streams instead of one).

How much faster? ......... depends.

I'd much rather get a 2 x 4GB kit, if only to leave the other 2 slots open were I to go to 16GB...

I don't know if it honestly matters that much.
But 2x4Gb gives you room for upgrade smile.gif
I guess it would put less strain on the motherboard too...
post #6 of 8
I'd go with 2x4GB any time but 4x2GB could be a good way to test for mobo defects, one of my new Z87 mobos crashed with all 4 DIMMs used yet was fine with 2 DIMMs in any position.

Real world you wont know the difference.

Usability wise, get 2 x 4GB so you can upgrade in the future...

No, get a 2x4 set to save $50! Thanks everyone, I was curious about this and search engines failed me. I will upgrade to 16 GB later on, but not now, unless there's an awesome sale. Remember in the early part of the decade when nobody needed more than 512 MB? And around the time DDR3 got released, no more than 2 GB? Now the recommendation is 4 GB, because nobody needs 8 GB! rolleyes.gif
