I only get 101 H/S on (stock bios) hd 7970 (r9 280x equilavent?) on claymore v.8. Is that normal or should i be getting more? My ram is ddr3 16gb, my cpu i7-4790 and i´m not using risers. 
I get more than that on a r9 280 (non x version)
RX 470 4GB - 170ish h/s (bounces around this figure on -i6) stock settings
what drivers do you use? mine is 16.10.2
I'm using the 15.12 version of the drivers. Using v.7 I was getting about 160h/s using -1 4
