I just put in 2 new ATI 5770s into my machine. 1 is in my second PCI-E x16 slot. The other is attached by an adapter to my PCI-E x1 slot. I previously installed an ATI 5770 card in my first PCI-E x16, which has been working fine. The card in the PCI-E x1 slot is working great, but the card in the second PCI-E x16 slot isn't. I'm running Windows 7. The second x16 card has shown up in my Display Adapters in the Device Manager, but I can't find it in GUI Miner. Both new cards have dummy plugs that I made myself. Anybody know what's going on here?

Dumb mistake. Cost me a couple hours of my night, but I figured it out. I had the dummy plugs resistors on that card backwards. My dislexia strikes again...

hey there...i'm facing almost the same problem. *bump*

have a hd5770 running on my mainboard (asrock k10n78FullHD-hSLI) in the pci-e x16 slot. (first monitor connected to this gpu DVI)

now i wanted to put another hd 5770 in the pci-e x1 slot (with a raiser 1x to 16x) but my win7 64bit wont recognise the second gpu. I have a tft connected to the second card as well with a VGA to DVI adapter.

What am I doing wrong? couldnt find anything. Or is it simply impossible to cennect an other gpu?

EDIT: the second card doesnt show up in harwaremanager...and its not possible to enable second screen in diplay properties

If it doesn't show up in Device Manager, then it's probably not related to a dummy plug. The card should show up in device manager as "working properly", but Windows will consider it "disabled" until it senses a monitor attached.

Try replacing your main video card with this one to see if the card is bad or something else. You could have a bad card, a bad driver (try reinstalling the drivers), or a bad motherboard (or the slot is somehow disabled).

reinstalled driver sveral times...no effect...

both cards work in the pci-e x16 slot...so the card is fine.

now i think the riser may be broken. i tried putting the riser to the gpu and pluget into the green pcie x16 slot. as a result i got a black screen.
it seems that the riser is broken or wouldnt it work in the x16 slot anyway?

can anyone confirm wheather or not a riser would work in the pcie x16 slot!?
