Installing new GPU

[kokujin]

I have had an EVGA 8800 GT for almost 2 years.I recently got an EVGA 9800 GT, I tried to swap the 2 cards, but the 9800 didn't take.I know it went to post, and booted up, but I see no image.I have an XFX 780i motherboard.I believe I did everything right, but maybe you guys can help, also can I run the two cards together?

Check to make sure you installed the 6-pin power connector to the 9800GT. This card requires a 6pin power connector from your Power Supply Unit.

Also, I don't believe the 9800GT and 8800GT will work together for SLI. However, you can use the older 8800 series for PhysX. So you could use the 9800GT as your main graphics card, and enable the 8800GT in certain games to perform PhysX tasks (Like Mirror's Edge)

The card is seated and powered.I see the fan spinning,but I see no image.My motherboard shows the boot code"FF", but I see no image.

Here's another thread dealing with the FF code.

Some folks say FF is "Fully Functional" and it means things are fine. One guy says he got the FF code, and ultimately found he had an 8pin power cable that wasn't seated properly (possibly for the CPU power?).

EVGA Addresses this issue on their version of this motherboard:

Basically they say to check the 24-pin Motherboard power cable and the 8pin CPU power cable.

The problem I am having is the fact my 8800GT will work, but The 9800 GT won't work.I just got the card through an RMA(my other 8800 GT died.)I'll look at it some more.

Might well have a defective card then. I'd get in touch with the manufacturer and start a support ticket and see if it needs RMA'd.

 

[kokujin]

That's the thing.The 9800 is from a RMA.I just got it recently from EVGA.

I'm a little off topic here but I have a question for the OP : do you know that the 8800gt and 9800gt are the same card ? The 9800 is a rebranded 8800, just like the 250's.

I know, and that what makes me upset.I thought I could just switch them, and have no problems, but it doesn't read it.

Is it possible my installation won't recognize another card for some reason.Like it's become linked to my windows, installation.

I tried again today, but no luck.I put the card in my second PCI E slot, and an error message came up saying I can't have a card in slot 2 without using SLI.Why is it I can actually get an image when the card is in slot 2, but none in slot 1?
