On the other two rigs, (Intel G2130, 8GB DDR3 RAM) even after using this command and the exact same settings as the other rig, CGMiner won't start on a TC higher than 8192. The highest I can get these cards at TC 8192 is ~595kH/s using 2 GPU threads.
Can anybody offer advice as to why this only seems to work on one of my rigs and not the other two? It seems although it confirms the setting has been changed this is not being applied, and thus CGMiner reports a memory buffer overload. Reading thread after thread of people pulling 650kH/s> with high TC is really starting to bug me when two of mine don't work for some reason
What OS/Catalyst are you running on each rig? What's the specific error you're getting?
Win 7x64, Catalyst 13.1, cgminer 3.1.1
I've executed
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
.bat file is:
cgminer --scrypt -o stratum+tcp://ltcmine.ru:3333 -u x -p xx --thread-concurrency 24000 --lookup-gap 2 --gpu-engine 1100 --gpu-memclock 1400 --gpu-powertune 20 -w 256 -I 19 -g 1
This works on rig 1, the error on the other 2 is:
Started cgminer 3.1.1
Probing for an alive pool
Maximum buffer memory device 0 supports says 536870912
Your scrypt settings come to 1572864000
Error -61: clCreateBuffer, decrease TC or increase LG
Failed to init GPU thread 0, disabling device 0
Restarting the GPU from the menu will not fix this.
Try restarting cgminer.
Press enter to continue:
I had just ignored it and have been running for a couple of months at a slightly lower kH/s with 2 threads at TC of 8192, but I can't help but keep coming back to it as I want to figure out why it doesn't work.
i also have the same issue work well on rig 1 and rig 2 doest work i dont know what to do
