I have just upgraded my computer to teh following: AMD Athlon 64 4000+, 2Gb RAM, Asus A8N Sli Deluxe Mobo, 2x Gigabyte nVidia 6600GT Sli Graphics cards. My problem is this. I have been using one of the Graphics cards for the last 2 years, no problem. I have just installed the second, flipped the EZ card over to two card possition, pluged in 4 pin power connector, put on the bridge, and then went into windows to try and enable the SLi in the nVidia desktop manager. However, the checkbox that the instuctions say should be there is not and there is a message saying I have to remove non Sli compatable graphics cards to enable it.
I've tried reinstalling drivers, I've checked the hardware manager and it recognises that there are two graphics cards and that they're both the same, one in port 7 on in port 8. I even tried disabling the one shown in port 8, but to no avail.
Oh, and I've also changed the BIOS setting from Auto to SLI just in case.
Got to admit I didn't follow half of the link you provided, BUT....the cards are EXACTLY the same, both GV-NX66T128D's from Gigabyte....think the point of the link was that he was trying to match two different cards and he acheived this by "downgrading" one to a 128 from a 256?
I'll have a play in the BIOS again and see what I can find. Thanks for taking time to help.
This is turning into a f***ing nightmare. Reading through the Asus manual there's a chapter on upgrading BIOS. Says that Asusupgrade will do it for you. Go to Start>All programmes>Asus and it's not there. Try to load it from original CD with mobo. Won't let me. Go to Asus website. Wait 10 minuted for it to load. Go to help page. Wait another 10 mins. Try to download Asusupdate. Try to both run and save it. No good.
