I know it's labeled X2, but it's basically a Phenom with 2 cores disabled so I thought this thread would be better located here, but I'm new, so what do I know?
I saw the other thread about DDR2 1066 with the Phenom II's, but what about the X2 7750? 2 slots populated with DDR2 1066 doesn't seem to be a problem for anybody, with 2x1GB or 2x2GB kits, provided the motherboard supports it, etc. But what about with all 4 slots populated? Results have varied widely here: some say they just can't populate all 4 slots, period. Others can, but they clock down to 800. Some that were clocked down are then able to manually set them back to 1066. I'm mostly concerned about populating all 4 slots with 2GB modules, as that's what I plan to do. Can anybody list their experiences here?
The memory I intend to use is 2 sets of Corsair 2x2GB TWIN2X4096-8500C5DF. If anybody could note successes with that particular memory with the 7750, that would be great as well.
We need to know what kind of motherboard you are using. It's the motherboard, not the processor that creates problems.

I have the ASUS M3A78 with 2x2GB of G.Skill DDR2-1066 (CL5) running completely stable.
Now, I'm assuming you'll be running a 64 OS system system since you want 4x2GB (all four slots), right?
I'll let you know in about a week if four sticks will run properly at the advertised speed.
I just ordered another M3A78 and will install an older 6000+ with Corsair 4x1GB DDR2-800.
My 9950 will eventually go into this system along with 2x2GB DDR2-1066.
From what I've been reading in the ASUS forums, I don't believe either model will be a problem for you.
Btw, the M3A79-T is a dynamite board, I wish I had the cash for it.
You may notice in my sig that my 7750 is OC'ed at 3.2 MHz (I haven't tried to push it further yet).
