Gigabyte GA-MA790FXT-UD5P AM3 Motherboard Pictured

So this board will use DDR3 with Dual Channel memory..

actually it will use DDR3 running in dual channel just like it did with DDR2

that is great news btarunr thanx a lot , woooooooooow first amd mobo with ddr3 1600

Just want to know, Do Triple Channel memory has more performance gain against Dual Channel memory.. Just curious.. If i'm using DDR3 1333MHz with triple channel setup, the memory bandwidth should be 10666 X 3 = 31,998.. Do the math like that?

is weird that only has 2 pcie whereas most 790 fx should have 3 or 4.

i guess they realized that it will be more economical to put 2 since most people that do crossfire only uses 2 cards

my Giga 790FX (DS5) only has 2 pci x slots..

What I DO like is the slots are now a full 16X each..Nice

And the Gigabyte ALC889A onboard sound is pretty nice too.

this board somewhat looks like a Jetway/Biostar (color coding)

I hope its a Strong Overclocker and costs less than Asus.

The 790FX chipset should have 4 PCIe slots, 790X should have only 2...

Aren't these supposed to be triple channel capable? Seems odd that there's 4 DIMM slots. I'd rather see 6.

Yes, the 790FX chipset supports 4 PCIe x16 long slots, but in this case Gigabyte is giving the buyer the choice to either buy a 790FX based mobo with 2 x PCIe x 16 or 4 x PCIe x 16. I only wish Asus would do such a thing. The 790GX is a great board, but in CrossfireX mode one lane is running at x16 where as the other is running at 8x which only bottlenecks performance.

I've had very bad experience with one of Gigabyte's mobo's but this one does look quite promising.

maybe in the future... will have a better memory controller quad channel 4x64bit or 2x128bit

What I don't like is AMD's CPU's only support DDR2-1066 per channel. So if you run all both channels at once which in my case I am with 8GB of DDR2-1066 memory, I am stuch running it at DDR2-800. I can always take out the 4 GB's (2 x 2GB) and have 4GB's run at 1066 but I didn't see an improvement at all, so I stick with 8GB and turn off the paging file.
