Any one recommend Which dominator gt ram, or the vengeance red ram as im going for a black and red theme i should go for. I have the asus maximus IV extreme-z intel z68 Socket 1155
I'm going watercooled
Conclusion of what to Buy
If you're the type of person that runs dozens of applications all at once, then a higher memory frequency does help, particularly when you're running demanding software. However, our testing shows that memory rated at over 1,866MHz doesn't give much extra performance. Worse still, in some applications only 1,333MHz memory gives a performance penalty, meaning that 1,600MHz memory is fine.
If you're doing anything other than heavy multi-tasking - this goes for gamers in particular - then a 1,600MHz or 1,866MHz kit is plenty. You could opt for CL8, as we saw some advantage in the video encoding test, but we wouldn't obsess over this factor, especially if a CL9 kit is much cheaper.
Always remember to buy from a reputable manufacturer, though, as cheap and unbranded memory tends to cause more trouble than the saving is worth. We'd also strongly advise you to opt for at least a 4GB, dual-channel kit. We expect 8GB kits to be common this time around, and these are worth considering if you run a few resource-heavy applications concurrently.
Final Words
I think we confirmed what we pretty much knew all along: Sandy Bridge's improved memory controller has all but eliminated the need for extreme memory bandwidth, at least for this architecture. It's only when you get down to DDR3-1333 that you see a minor performance penalty. The sweet spot appears to be at DDR3-1600, where you will see a minor performance increase over DDR3-1333 with only a slight increase in cost. The performance increase gained by going up to DDR3-1866 or DDR3-2133 isn't nearly as pronounced.
Therefore, we believe that inexpensive DDR3-1600 SDRAM with not very aggressive timings would be the most reasonable choice for contemporary LGA1155 systems: in our opinion, memory like that offers the best price-to-performance ratio today.
