How would I go about deleting an algo from the SALFTER MPH switcher? One of my cards just doesn't like keccak.
Open the mph_switcher in gedit and prepend a # to lines referencing keccak.
There shouldn't be references to any particular algorithm in mph_switch.py IIRC; it's algo-agnostic. mph_conf.json is where you'd want to look.
Another GPU arrived yesterday. I put those changes in to facilitate benchmarking: run an algo for a bit, note the hashrate and power consumption, move onto the next. This time, I also had the sense to note the difference between 3 and 4 GPUs, so that as I add the remaining GPUs to this rig, I can just tweak the config file appropriately and get back to mining. Here's the result of that:
for each MSI GeForce GTX 1070 Gaming X 8G:
115 W pwr limit, all except Ethash: -100 gpu_oc 0 mem_oc, Ethash: -200 gpu_oc 1000 mem_oc
Cryptonight: 95 W, 780 H/s
Equihash: 129 W, 420 H/s
Ethash: 131 W, 34 MH/s
Groestl: 134 W, 30 MH/s
Keccak: 124 W, 446 MH/s
Lyra2RE2: 129 W, 29 MH/s
Myriad-Groestl: 135 W, 55 MH/s
NeoScrypt: 130 W, 750 kH/s
Qubit: 133 W, 18 MH/s
Scrypt: 127 W, 640 kH/s
Skein: 137 W, 355 MH/s
X11: 127 W, 11 MH/s
(Power's measured at the wall with a Kill-a-Watt. My GPUs are powered by a 750W HP server power supply through one of those PCIe breakout boards.)
