DDR3 - 4 x 2GB Vs 2 x 4GB

[nataSofCols]

I'm trying to see if there are any performance impacts of going with 4 sticks of 2GB DDR3 vs 2 sticks of the considerably more expensive 4GB DDR3. Most of what I've been able to find are posts from over a year ago on older hardware. I will be running a Core i7 860 on an Intel DP55KG. The memory will be G.Skill DDR3 1600. I don't have any plans for overclocking the system.

If you run them at their rated speed, then the performance will be the same. The 4 GB modules are better only if you need to install 16 GB.

Edit: G.Skill normally guarantees that only 2 modules will run at the rated speed. You might need to run them at 1333 MHz if you install 4 modules.
