It has a 4th short slot I can fit a riser card into but I can't get it to recognize more than 3 cards. It has a 4G toggle that doesn't seem to do anything except screwup the ability of the display card to display. Tom A proud member of the OFA (Old Farts Association). ID: 1983854 ·

I hadn't thought of those ideas. I apparently had Bios 1.05, upgraded it to 2.0 including the recommended "all in one" driver install. And broke something in Seti. Now I am getting "postponed" applications on all gpus. I am up to 4 will try 5 next :) --Edit-- 5 is recognized but Seti is still broke. I will start another thread on this specific issue. --edit-- Tom A proud member of the OFA (Old Farts Association). ID: 1983901 ·
