BufusTurbo Posted January 20, 2019 Posted January 20, 2019 Hi all. I have two Nvidia Geforce GTX 580 video cards installed in my pc, connected with SLI cable. Lately my graphics performance dropped and so I reinstalled my drivers. While doing so i noticed only ONE video card is listed in the device manager and the Vram is only 1.5 GB (should be about 3), and Nvidia Inspector only "sees" one card while last time I checked a couple months back it detected both. Fans in both video cards are working so I think both are powered properly and both are correctly sitting in their proper places in the motherboard (an ASUS Rampage Extreme IV). I have a protected power supply so chances of components being fried by shenanigans from the power supply are minimal. I keep all hardware clean with compressed air and do so once every two-three weeks. Â What should I do to fix this and get back my previous performance? What steps are necessary to check the health of my cards? Â
BufusTurbo Posted January 20, 2019 Author Posted January 20, 2019 Update: I tried them one at a time and one works. the other, on device manager, keeps giving me the error code 43 even though I reinstalled it six times. I guess it's shot to hell...

BufusTurbo Posted January 21, 2019 Author Posted January 21, 2019 I don't know anyone with a compatible motherboard. Thing is, now my pc doesn't even "see" the suspect GPU anymore. dang.

(2) Well, that means only one thing. Like it or not you already know it, sorry about it.
BufusTurbo Posted January 23, 2019 Author Posted January 23, 2019 Eh, I luckily found a replacement, but I think next time I'll just have to switch to something more recent. Those are a tad rare to find.
