GMINER CUCKATOO31 low hashrate

[fk2]

Hi I get low hashrates with CUCKAROO31 and a rig that has 1 1080 and 2x 1080TI cards. I'm using nvOC 3.2 stable (Linux).

1080 with 120/1200 clocks, 160PL does 0.46G/s
1080ti with 120/1200 clocks, 200PL does 0.67G/s

The whole rig draws a total of 653W off the wall and makes a hashrate of around 2.4G/s . According to Whattomine this should be around 4.35 but Mh/s instead of G/s. I guess the naming is wrong on WTM?! When I compare to ETH, BEAM, X16R, CUCKAROO29 everything is fine so I somewhat doubt its a problem with the gpu or clocksettings or PL.

Any ideas?

There are two variants of Grincoin mining. CuckARoo (for GPU only & 6+GB VRAM) and CuckAToo (for ASICs & GPU w/ 11+ GB VRAM)
Now you are mining CuckARoo31 and as you can see from the pool given below, a 1080ti can do around 0.551 g/s which is less then what your rig is capable of.

Anyway, Grincoin uses Graphsize as a parameter rather than Hashes which most of PoW coins use.
So the unit is graphs per second (g/s) rather than hashes per second (h/s)

So, the conclusion is, there is no problem with your configuration.
