Hopefully someone may be able to assist..
Ive set up my new miner running cgminer, and I am hashing - but getting extremely low results and the computer keepd freezing.
I have tried a variety of variations on the config file, but the current one is:
"intensity" : "16",
"vectors" : "1",
"shaders" : "1792",
"thread-concurrency" : "8960",
"gpu-engine" : "925",
"gpu-memclock" : "1350",
"gpu-powertune" : "20",
"gpu-threads" : "1",
"worksize" : "256",
"scrypt" : true,
"kernel" : "scrypt",
"kernel-path" : "/usr/local/bin",
"lookup-gap" : "2"
I can get a higher hashrate upping the intensity, but then the whole system freezes within an hour. On the current settings I can run overnight (did the first diagnostic yesterday eve), but am averaging 1.4 mh on three cards (around 4-450 each), and if I introduce more cards the system crashes within minutes. Also, even when Im only running three, everything runs fine unless I even touch the mouse, then the hashrate stops (Im using my laptop on SSH to command the miner).
The only conclusion that I could come to, is that I dont have enough Ram - Im running 4 gb (2x2) of corsair ram - and the problem that keeps occurring, i.e system freeze is symptomatic of not having enough ram - although it could be a lot of other things as well I suppose (bad version of linux, etc..).
You'll notice the thread concurrency is quite low, I did this as a result of seeing something somewhere about the TC and low ram balance..
Any help would be greatly appreciated!!
Thanks
Has anyone had similar problems
