GA-MA785GT-UD3H Memory placement 1x4gb & 2x1gb

[webster]

I did not see a search box here, so I'm posting blind.

I  have 2 x 1gb ballistix pc3 - 12800 cl8 1.65 volt which I replaced with:

1 x 4gb G.SKILL RIPJAWS  DDr3 1600 PC3 12800 CL9-9-9-24 1.5v.

Common sense and the manual infer that the 1gb sticks go in dd3-1 and ddr3-2

and the 4 gb stick in either ddr3-3 or dd3r-4.  Does it matter which?

First off, will this work on a 64bit Win7 Ultra?

Next, will I see 6GB total memory?

Are they dissimilar enough not to attempt this??

Thanx

CPU is AMD Athlon II X4 630

It is not going to run dual channel either was so put the 2 x 1 gig sticks in the first two slots then the 4 gig in the next.

Okay...

That supports what I suspected.


Sure appreciate the reply and the hellp!
