So now a few more questions:
1) Should I be happy with 25MH or should I push for 28 on these RX480 Shaphire Nitro+ 4GB(Elpida)? If so how do I do it? I currently have the Anorak Memshift Bios installed (when I had the overclocked Bios it tipped my PSU over 1200 when it tried dual mining). Would I need to go back to standard bios before trying any mods through claymore? What should be starting point and where should I be expected to get to?
2) Does anyone else have problems with their USB Risers? Mine every so often come slightly loose (think USB cable moving it) and it causes a crash. Thinking of putting cable clips on the frame to stop the cable from moving freely between GPU and risers but wondering if actually required.
Thanks
1)
if you are using "AMD blockchain beta driver" which contains the DAG patch you should not be happy with 25MH for nitro+ (8GB models can do 29+ stable) 27.5 in dual mine is the lowest you must be getting running at low power
2)
noone should be moving around the rigs. yes some raisers have thin pciex1 boards that move easily. I find horizontal usb connector to be more stable in this regard
