Title: GPU in 2nd PCI-E x16 Slot Not Showing Up Post by: the_joey_o on June 18, 2011, 05:07:55 AM 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?

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 Title: Re: GPU in 2nd PCI-E x16 Slot Not Showing Up Post by: carbolic on June 24, 2011, 02:39:12 AM 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).

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!? |
