View Full Version : 2 asus en6600gt cards no sli
I have 2 asus en6600gt pci-x cards both with same part number.
I ame running xp-64 with nvidia 76.80 drivers on an a8n- sli mobo.
one card is about 2-3 months old and the oher one is brand new.
When I go to the sli-multi gpu setting it says i need to remove non sli compatible card to enable sli.
Can you get SLI to work with the normal WinXP 32??
I don't have xp-32 to try

Are both cards running the same BIOS? If not, rip the BIOS off the newer card and put it on the older one.

What Sub said plus i'd recommend xp-32 with 71.89 drivers as a base for testing since Win64 drivers might not be mature enough to be trusted.
Yes definetely check the BIOS revision to make sure they are both the same
how do you "rip" the bios from one and put it on the other?

First check to see that the BIOS versions are indeed disimilar. Do that by checking each card individually. Uninstall your drivers, remove one card, boot, install drivers, check the BIOS version in the driver control panel, uninstall drivers, swap cards, repeat the process. Whichever card has the newer BIOS revision, put in your machine and use the nvflash utility (Google search it) to create a backup of that BIOS. You'll need the ability to boot into DOS for this. It's why I always kept a Windows 98 boot disk and a floppy drive handy.

Can I mix and match graphics cards?
No. NVIDIA currently doesn't support SLI on two different models or from different vendors. SLI supports configurations with the same model (i.e. 6800 Ultra) from the same vendor (Vendor XYZ). A common misconception about SLI is that the BIOS revision has to be identical between the cards. This is not true. A manufacturer can revise the BIOS without affecting SLI. NVIDIA does however recommend that customers confirm SLI compatibility with the manufacturer before making a purchase

So according to that, it should not make any difference what the bios is as long as it's from the same manufacturer and is Sli compatible.
The bios is different for both cards. I will update the older one tomorrow and see what happens.The software says both cards are sli compatible when they are each installed by themselves. Since they are both the same card it almost has to be the bios.We will see.
When I try to flash the old card with the bios from the new card it says pci subsystem mismatch. What now? I am useing nvflash ver. 5.10
I got the bios updated and sli works now!!! Thanks for all your help!!
