Which DDR3 RAM would work best in this system?
Ok, I have decided to try my G2020 in a security rig until I can find a good deal on a 3570k or a 3770k. I also found a new Corsair CX430M sitting around in my inventory so I thought I would give it a shot [purchased it 3-4 months ago for only $15 new].
I had to remove the Corsair Vengeance RAM because they are too tall.
Which of the following RAM would work best, or does it even matter?
Kingston HyperX Red KHX16C10B1R/8 8GB Memory Module - 1600MHz, 10-10-10, DDR3, CL10, 1.5V, Unbuffered
Patriot Signature Line 2X4
By filling only one slot with 8GB, will my system use less power?
And what about the Kingston Hyper X CL10? Is it much different than CL9? Do you foresee any problems if I use this RAM?
