how many cards 890fxa-gd70 support up to?
In my experience 890FXA has some problem. I don't have MSI, but bought Gigabyte 890FXA-UD7, hoping i can run 6 cards, but 1st even though i used AMD phenom II X2 555 64 bit processor, it doesn't allow me to install & work with Windows 64 bit & Ubuntu 11.04 64 bit.
Since default BIOS dated 23/7/2010 failed, i updated to 23/8/2010 F4 & that too can't.
Then after installing the BETA BIOS F5e only Windows 64 bit or Ubuntu 64 bit worked.
Then for the cards, eve though it has 16x_1, 16x_2, 8x_1, 8x_2, 4x_1, 4x_2 & they have mentioned that it can work with 4 cards in 8x mode, it always gives me atimpag.sys blue screen error, if i install 4 cards in 16 & 8 slots.
Only way to make work is to connect 2 cards in 16x slots & 2 in 4x slots.
You can't use 6 cards in this board.
Better go for 990FXA ******..
