So I am considering to add more ram. Right now I have 3x1gb Kingston ddr3 @ 1333 mhz. And since the ram prices have dropped and I have upgraded from w7 32 bit to 64 maybe I could fill my empty slot. I am looking at a kingston 2gb ram with same mhz and voltage.
Would there be any problems pairing it with a 1gb version?
Would I notice any major performance boost from 3gb to 5? (doing some gaming(dota 2, d3 etc.))
My system: W7 64bit
Amd phenom II 955
3 gb ddr3 ram
asus m4a79xtd evo
I would either get a 4th stick of the same 'Kingston' you have now, or get a 2x4GB kit and eBay/File-13 the 3x1GB. Ideally, for gaming on any platform 8GB is the 'magic' number, and sure you can game on 4GB. Also, don't mix-match RAM - it's an accident waiting to happen.
