So I have a bit of a head scratcher maybe one of you can help me out with.
I have 4 cards - 2x Gigabyte OC Gaming RX560's, one XFX RX560 4gb and 1 asus 4gb RX560. When I have them all hooked up, the gigabyte cards get around 13.5mh/s, the xfx gets 10.5mh/s and the asus gets 9.5 mh/s. All are set to Compute mode except for the Asus which for some reason I can't as there is no option to do so. Here is the head scratching part...The gigabytes always get around 13.5, but one day I disabled them just to play around and the XFX and Asus cards jumped up to 13 & 12 respectively. I plugged the gigabytes back in and boom they both went down again. I thought it could be a power supply issue as I only had 500w. I bought a 750 80plus gold Thermaltake PSU with the hopes and dreams of solving this issue but alas...it did not. I know I should just chuck those other two and get two more gigabyte cards but i have sunk more money into this than I wanted to already.
Any ideas you folks may have would be greatly appreciated!
PS...I have modded the bios of all 4 cards, the asus even shows as 16CU now.
