did cleaning the slot fix the issue? I just noticed you have a CX psu. those have been shown to not perform correctly when over 30C and judging by the fans in your case and you overclocking a reference card is it possible the psu fried the slot without frying the card?
Cleaning the slot did not fix the issue. The slot is definitely dead. The card was always fine, it still works and I'm running strong in slot 2. No issues at all and I've had several long gaming sessions. I've got a nice stable overclock at 1349MHz (turbo frequency) and temperatures are looking good at 78-82 full load on the GPU.
Probably should have cleaned it before putting in that GPU. Too late to do that now. It can burn up probably if some contacts have too much resistance. I guess I wasn't too paranoid when I covered my slots with electrical tape when I would be GPU-less for a long time.
Hi guys I'm not a nerd. I bought a Sapphire RX 480 Nitro. Haven't overclocked it or touched it at all but it worked at first for a few days but would only work while my HD6570 was in slot 2. Once I took that out it the 480 would disappear too from device manager. Weird. Anyway clean installed Windows 10 with the 480 and its not even detected. Looked around found this and sound like my symptoms. I see no scaring around the slot at all and why should I? Thing was only running for a few days and I haven't stressed it yet. So I also moved mine to slot 2 and it is currently working. I'll test my R9 280x in slot 1 and see if that still works. My question is what legal right as a customer do i have if an AMD card killed my Gigabyte mobo?
