I have evga 1000 gold and rosewill 750w gold.
I am wondering where shall I put 2 x 290, 1 x 270x, mb, riser and etc.
1. 2 x 290 non x and riser sata on 1000 and rest on 750w
2. 2 x 290 non x on 1000 and riser, 270x rest on 750w
which one is better?
this is my config:
{ "pools" : [ { "url" : "stratum+tcp://us.clevermining.com:3333", "user" : "unknown", "pass" : "workerpassword" }, { "url" : "stratum+tcp://useast.wafflepool.com:3333", "user" : "unknown", "pass" : "backupworkerpass" } ] , "intensity" : "20,20,19", "worksize" : "512,512,256", "lookup-gap" : "2,2,2", "thread-concurrency" : "32768,32768,16000", "gpu-engine" : "1000,1000,1100", "gpu-memclock" : "1250,1250,1465", "expiry" : "5", "failover-only" : true, "log" : "5", "queue" : "0", "scan-time" : "1", "device" : "0-2", "gpu-powertune": "0,0,2", "no-submit-stale" : true, "gpu-threads" : "1"
it seems that both of my 290 ( both xfx)
xfx 290 ref - 860 kh/s and around 700-800 WU/s ( around 750 marks) and no higher xfx 290 non ref- 750 and around 600-700 WU/s
why is that low? please help me.
