"There is RAM the will work as {1/2/4} DIMM support; DIMM socket support {1} works with (1) stick, DIMM {2} only works with Dual Channel, and DIMM {4} requires Quad Channel. Therefore, my 'assumption' is that you 'current' DDR2 is the DIMM {1} type"
Ideally, you want your RAM to work at least in Dual AND Quad Channel support.
The Phenom II x6 1055 is its' own puppy and has its' own Memory Controller so you need to be careful whenever you choose RAM and in addition it supports very fast RAM ~2000MHz.
In my particular build, I am trying to find 2000MHz compatible kits which is very difficult to find, and more than likely I'll need to either buy it overseas or direct from {Corsair or G.SKILL}.
{I build 1-2 rigs/month - paid hobby thing. This is for a new referral 'customer'} In real life I own an IDX/REO Database company, but we all have our hobby's. This is a tentative, I'm in the middle of spec'ing list of components.
