I'm afraid to damage my recently bought R9 280x (used). My motherboard is an old ASUS P5GC-MX/1333, with one 1.0 pci-e x16 slot. Two graphics cards have been damaged for a weird (or not) reason: 1 Geforce 8500GT and 1 AMD HD 6450.
My R9 280x crashes my whole pc whenever I try to access the BIOS, while it worked correctly in another MOBO. Since I'm too poor, I didn't want to replace my MOBO, unless you guys can say for sure that I'm at risk by using this pretty old motherboard. I will use it to mine Ethereum and Decred, and it will be running the whole day, non-stop.
EDIT: my reply has been deleted for some weird reason. Just because I said "Well, this has nothing to do with what I'm going to mine. Just read it as "I will use it to mine Bitcoin" (lol), and you will be fine.
"
Also, it's funny that my thread is in mining section now... because my doubt has
nothing to do with mining per se.
