I have 10 rx 470 4Gb nitro+ sapphire. Some of them have bad basic quality (60%, better than 1.5% of similar GPU's) and they run at 29.5Mhash stable because they have samsung memory.
So i would say that the real problem in my GPU's is the memory, GPU's with Heriox memory are shitty and i cannot run the higher than 27.5Mhash even though they have high ASIC quality.

I for the life of me cannot get any of my 470s flashed because Atiflash says it can't read my memory, after doing research on this, I found a way to troubleshoot it was to set the pcie speed to gen 1 or 2 in the bios but in the bios of my gigabyte x79 I see no such option. Anyone have any advice? I've got four 470s and they're all running at 14-20Mh/s Undecided
