I am getting a quite strange error message when trying to scrypt mine with 3x 7950s in an older Core2Duo machine.
Without setting ANY parameter (not even intensity) just pool data, I am getting the following error:
Error -5: Enqueueing kernel onto command queue. (clEnqueueNDRangeKernel)
All 3 GPUs are set to OFF and no mining whatsoever
Drivers ver 12.8 and SDK 2.7
Any idea what that could be?
Could it be that there is an issue with the machine having only 2gb of ram?
"
Without setting ANY parameter..." So you don't any *.conf in your cgminer folder?
"
All 3 GPUs are set to OFF..." How did you set the GPUs to off if you didn't set any parameters?
As for memory, I keep hearing how scrypt mining is very RAM intensive. I've heard you need more RAM than you have video memory. I don't see that with my miners, e.g.:
Dedicated 4x7970 miner has 12 GB GDDR5 plus 10 GB DDR3 and I still have 8.69 GB available.
Dedicated 3x7970 miner has 9 GB GDDR5 plus 4 GB DDR3 and I still have 3.02 GB available.
2x7970 on my workstation, several other programs running, has 9 GB GDDR5 plus 8 GB DDR3 and I still have 5.36 GB available.
You might want to go to 4 GB but I suspect your problem is elsewhere.
