[DDR3] 6GB @1600MHz x 12GB @1333MHZ

[jemm]

For gaming which config is better [DDR3] 6GB @1600MHz or 12GB @1333MHZ?

6GB is plenty enough for gaming.. Also, considering a gaming rig will surely employ CPU overclocking, 1600 MHz memory set is ideal..

Thanks for your reply Emperus.

Actually I have 3 memories kits of 6GB each (3x2GB) -- I can use just 2 kits tough. The kits are DDR3 1600MHz, ´low latency´ 8 8 8 24.

When I use it with 12GB, I downclock the memories to 1333MHz, but I use a more agressive timings 7 7 7 21.

The difference I feel is that with 12GB it appears to be a bit more smooth, but I haven´t undertaken any test to confirm it.

Anyone out there have knowledge of any test/review on this, and how it could impact the performance?

Thanks!

There's a gain with 'some' games 6GB vs 8GB+ and in practice the 1600 CAS 8 is faster then 1333 CAS 7, and if those kits are Dominator {CMP6GX3M3A1600C8} then try OC 1800 MHz CAS 8/9. Better than Guessing...run some benches

Good article -> http://www.tomshardware.com/reviews/ram-memory-upgrade,2778-8.html

Any OC of RAM greater than Rated always test with Memtest86+.

if ur considering gaming, dont buy RAM with the priority on SIZE... buy ones with higher speed... ther are reasons why there are 4 gb sticks pack cost well over £150 thats over $300 for u americans.
