I use two GPU, undervolted and 1261mhz-861mV core, 1950 mhz-861mV memory with 230watt at wall.
I've modify my command line in:
gatelessgate.exe --gpu-platform 0 -k nist5 -o stratum+tcp://pool.solariscoin.com:3032 -u tony_crunk.worker1 -p x -d 0,1 -I 20
with 16.22Mh each video card.
I suppouse sgminer and gatelessgate have same performance... I can try it...
niest5 depends from GPU or memory?
I got better results with SGMiner 5.5.5 than with Gateless Gate. Intensity setting of 128 works well, intensity setting of 256 is too intense and leads to crashes. Algorithm "talkcoin-mod" "nist5" same thing, same hashing speeds. Set a high fixed fan speed.
My SGMiner .CONF file looks like this:
{
"pools": [{
"name": "Solaris",
"url": "stratum+tcp://pool.solariscoin.com:3032",
"user": "LoginName.WorkerName",
"pass": "WorkerPassword",
"profile": "solaris"
}],
"profiles": [{
"name": "solaris",
"algorithm": "talkcoin-mod",
"Intensity": "20",
"worksize": "128",
"gpu-threads": "1",
"gpu-powertune": "20"
}],
"default-profile": "solaris",
"no-extranonce": true,
"no-submit-stale": true,
"temp-target": "75",
"auto-gpu": true,
"gpu-fan": "55",
"temp-cutoff": "85",
"temp-overheat": "90"
}
Try that and compare to GatelessGate.
