I have 2x Sapphire Radeon R9 290 4GB (Hawaii PRO) and a XFX Black Edition 1250W 80+ Gold.
I'm thinking of buying 2x Gigabyte R9 280X Dual-X 3GB and put in the same miner.
How will this work W-wise and what would the config .bat look like in cgminer 3.7.2?
This is a proper conf file for sgminer 4.1.0, it lets you run one and two gpu thread devices in the same instance and is faster than cgminer, use it:
{
"pools" : [
{
"name" : "Wafflepool",
"url" : "stratum+tcp://useast.wafflepool.com:3333",
"user" : "13jFjtuKoCfSd3bkLJQJg7EoBXWmebvA8x",
"pass" : "x",
"pool-priority" : "0"
},
{
"name" : "middlecoin",
"url" : "stratum+tcp://useast.middlecoin.com:3333",
"user" : "13jFjtuKoCfSd3bkLJQJg7EoBXWmebvA8x",
"pass" : "x",
"pool-priority" : "1"
},
}
],
"intensity" : "20,20,13,13",
"worksize" : "256",
"lookup-gap" : "2,2,2,2",
"thread-concurrency" : "32768,32768,8192,8192",
"temp-cutoff" : "99,99,99,99",
"temp-overheat" : "95,95,95,95",
"temp-target" : "90,90,90,90",
"gpu-engine" : "0-1000,0-1000,0-1000,0-1000",
"gpu-memclock" : "1375,1375,1500,1500",
"auto-gpu" : "true",
"gpu-vddc" : "1.15,1.15,1.15,1.15",
"gpu-fan" : "85-100,85-100,85-100,85-100",
"gpu-powertune" : "20,20,20,20",
"expiry" : "1",
"failover-only" : true,
"log" : "5",
"queue" : "0",
"scan-time" : "1",
"gpu-threads" : "1,1,2,2"
}
This setup will run at 1100w gpu wise plus 100w-150w of ram/hdd/cpu/board, without undervolting (if the gpus are voltage locked)
To use it you have to create a txt file and name it sgminer.conf, then edit it and paste this inside and save. Then just run the sgminer.exe file to start mining using the conf.
