The MSI is actually 790FX-GD70 and 790GX-G65 BUT why only
Supports four dual-channel DDR3 1333 memory slots up to 16GB
I thought DDR3 was going triple channel??
Nah specs for am3 reference mentions nothing about triple channel, read the white paper in post 1.Quote:

Why? The amount of channels has to do with the memory controller not the RAM type.Quote:

Not on AMD. The same chipset can be recycled over and over again as the only contact it has with the memory is through the HT link it has with the CPU. That's why all first gen AM3 boards are going to feature the venerable 790FX/GX that we've known and loved for the last year.Quote:

Let's keep it real here: Triple channel memory controllers do offer an advantage, but it's far from universal. Just like in the old days when dual channel DDR controller debuted, not everything benefits and there are some drawbacks. I say do it when it makes sense financially. Until then, I've got no problem with dual channel.
Fwiw in some applications dual channel with intel chips is faster in certain apps than triple channel.......bigger is not always better........Quote:

Well for 1, not everyone runs vista, for 2 not everyone runs 64 bit so....since xp only recognizes 3.5 max ( in most boards w/XPsp3 32bit ) 3g is just fine. Vista 32bit only recognizes 4g I think in 32bit......
