which memory is the best
just rebuilt system into new case,cosmos 2,ga z68xp ud34, i5 2500k, sli gtx 580 using memory from previous case 16g hyper kingston genesis,4x4.
im going to build up old case for daughter and use my kingston for her.
i mostly use cosmos for gaming, can anyone suggest the best ram for my useage price is immaterial and looking to overclock soon.

thanks.
 
Why not keep the Kingston RAM (what speed is it?) for yourself and buy a cheap 4GB/8GB kit for your daughter?

Sandybridge doesn't benefit from faster RAM and 1600Mhz is the perfect balance between price/performance.

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.

1600MHz offers the best price/performance ratio.

That's not to say there isn't a small benefit in some circumstances from RAM faster than 1600MHz it's just that for most it isn't worth the extra cost.

If price really is immaterial then you can pay the extra cost for the Samsung RAM and it'll give a small performance boost in some circumstances if you overclock it.

The sensible option is to stick with what you have and buy some cheap RAM for your daughter's PC.
 
sorry not changed fans round yet on cpu cooler been busy this week doing it at weekend and changing fans at the same time.
