"which probably means that you have to increase the size of your page file to at least 16 GB. Let us know if the increasing of the page file size (you have to restart Windows after that in order to apply the changes) doesn't solve the problem."

I had 25Gb pagefile size when i ran PhoenixMiners Sad

Please try the new version 2.6b. It is possible that the new OpenCL initialization code introduced in 2.5d is not working well with your driver and if this is the case, 2.6b should solve the problem. Another possible way to fix the problem is to create a batch file to start the miner with the following contents (the important part are the setx statements to set the environment variables):

Code:

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

PhoenixMiner.exe -clKernel 1 -pool eu1.ethermine.org:4444 -pool2 us1.ethermine.org:4444 -wal 0xd8081f58c43bd84f9a7882f613a9d8947fb31d00.farm1
pause

I try PhoenixMiner 2.6b with recommended above parameters, on Farm1 PhoenixMiner didn't start and show the same error "clCreateCommandQueue (-6)" but on second Farm PhoenixMiner started up and started working. After restart PhoenixMiner on Farm2 I recive error "clCreateCommandQueue (-6)" again Sad

I try restart PhoenixMiner and MSI Afterburner several times and change parameter GPU_FORCE_64BIT_PTR from 0 to 1 and backward - i have achieved success several times (PhoenixMiner
started UP sometimes)..

What i noticed, when Phoenix starts up normally Phoenix define 4GB VRAM, when Phoenix can't starts, it define only 3GB VRAM

My rigs have 2GB RAM Memory (900-800 MB free when all works)
Sorry for my english)
