2x2gb 1600 vs 4x2gb 1033

post #1 of 5
Thread Starter 
Well I have 2x2gb ddr3 1600 and 2x2gb 1066 laying around and am putting up a spare/ TV gaming rig. Games will be like BF3 (duh) MW3 (maybe) need for speed games and dirt3. 1 monitor at 1080p. Should I go with 4x2gb @ 1066 or 2x2gb @ 1600?
Phenom II 840
4870's crossfired

Edit - replace 1033 with 1066
I am talking about mixing and matching different speeds of ram (which i assume would downlcock the faster ram to the slower ram)

Um, do you mean 1333 when you said 1033?? Also, just to clarify, you have 4gb of 1600mhz and 8gb of 1333mhz total to choose from? Just a few typos so it is hard to tell exactly what you have.

Sorry it is 1066. I have a TOTAL if 8gb ddr3 on my desk. 2x2gb 1066 abd 2x2gb 1600.
I think that if I start mixing and matching ram speeds it will downclock the faster ram to the slower ram speeds.

OK, yea, just run the 2x2 1600. Your right, if you mix the kits they will down clock to 1066 which is pretty slow. If they had been 1333mhz I would have said run all 8gb because you mentioned BF3 and 8gb at 1333mhz would be better, but 1066 is slow.

Don't mix performance RAM with generic RAM or you may run into issues... BF3 loves bandwidth if I'm correct.
