Hi,
I tried to run Cryptoslax on my own today but have some trouble with segementation faults.
First, until now I run BAMT which is 32Bit and therefore only 2GB of my 8GB were available.
With Cryptoslax I hoped to be able to increase thread concurrency from 24550 to 32765 which should be best for R9 290.
However, even with TC=24550 I get errors from cgminer-opencl and also with the self-compiled sgminer 4.0.0:
[11:55:13] Failed to init GPU thread 0, disabling device 0
[11:55:13] Restarting the GPU from the menu will not fix this.
[11:55:13] Try restarting sgminer.
[11:55:13] Maximum buffer memory device 1 supports says 1073741824
[11:55:13] Your scrypt settings come to 1608908800
[11:55:13] Error -61: clCreateBuffer (padbuffer8), decrease TC or increase LG
This is my config:
"intensity" : "21,21,21",
"worksize" : "256,256,256",
"thread-concurrency" : "24550,24550,24550",
"gpu-engine" : "1075,1075,1020",
"gpu-memclock" : "1470,1375,1465",
"gpu-powertune" : "20,20,20",
"gpu-threads" : "1,1,1",
"lookup-gap" : "2,2,2",
Any ideas?
TC is "GPU thread concurrency" i doubt it has anything to do with your system memory, TC mostly are number of GPU execution thread to be spawn to run on your GPU and use your GPU memory
