Hi Gooday

What kind of CPU do you use?
How many pieces of memory sticks you have and in which slots are installed ?
Do you see "DCT mode" function under M.I.T. and if yes then what option?

Thank You, runn3R

Here is my spec
CPU   Phenom II x3 720 Black edition
Ram  Corsair CM2x1024-6400C4   1Gx4 = 4G
Display card  Ati X1950 pro x 2   in Cross-Fire mode

Yes, I have that DCTs mode appeared in BIOS , I can choose  unganged mode  and ganged mode in BIOS, BUT the problem is, after I hit F10 and yes to restart the machine, still unganged mode , NOT CHANGE in POST and CPU-Z in windows.

We have tested 2 or 4 pcs of memory and set in bios as ganged then POST screen also shows ganged.
When installed 1 or 3 pcs of memory and set in bios as ganged then POST shows as unganged.

Please check you memory, try what happens when only 2 pcs installed, try to change into other memory vendor.
