Is there any difference between ddr3 2400 vs ddr3 1600

I hear 8gb is enough for games
Im going to be getting 2x 8gb
Since this is overkill for games should i just get 1600? is there any diference if i get 2400

thank you

First unless you're looking at an Ivy Bridge forget DDR3-2400, you might add +0~4FPS from DRAM Frequency alone with DDR3-2400 vs DDR3-1600 'IF' you OC the CPU (best case), B-U-T you add a much higher risk of instability as the 'cost.' You're many times better off getting a better non-reference GPU and OC'ing the GPU with MSI Afterburner which works on any recent and current GPU.

/edit - 8GB (2x4GB) is plenty enough for gaming, and if you want 16GB you'll have less issues with a 4x4GB kit DDR3-1600 CAS 8 or 9 memory. 8GB/stick especially at higher Frequencies or lower CAS Timings also adds unwarranted instability; 8GB non-ECC kits still need some work and improved IC's. BF3 example: 3.0GB~3.5GB game & maps + 3.0GB~3.5GB Shared Memory (GPU) + 1GB~1.5GB OS & background.

Bottom-line, spend the money on other stuff -- namely a better GPU.

Expect around a 2% difference in memory performance going from 1600 to 2400; 8gb is the new standard for gaming PCs since we multi-task. I am just using 6.5GB idle right now out of 16gb.

You should spend the extra money on a better GPU that has something like Asus DirectCU II to keep the card cool at high overclocks.


So in conclusion 8gb-1600 is fine, spend the extra on a good GPU.

I'm going to step out on a limb and say there is a difference, although only 1 to 3 %

1600 is definitely the sweet spot and great value for money, try and get the lowest CAS timings you can for example 8-8-8-24 will perform 0.5% (guessing) better than 9-9-9-27. Hey it's nothing, I know, but it's good to know ;)

Don't go anywhere above 1600, 1.5v, and no more than 9-9-9 timing.

Most forums, reviews, and threads you will see that they all say you will never see any real world improvements in RAM.

I currently have 12GBs of RAM @1600MHz 7-8-7-21 at 1.5v.

Like others have said spend the money on something that will actually benefit you.

You literally won't see any difference unless you are those obsessive benchmarking types and even then it won't be that significant.
