Hi all,

I have previous experience mining eth on a pc but I was out of the game for quite a while.

I have since set up an EGPU on my laptop with a 8GB R9 390X and its working perfectly for mining ZCash using Claymores miner however I cant for the life of me get it to mine ethereum with claymores dual miner.

the error message is along the lines of:

GPU0, OpenCL error -5 (0) cannot create DAG on GPU

Now when I was mining last year I had a similar issue running 2GB cards but this is 8GB.

I have already increased the virtual memory to above 16GB

I am using the 15.12 drivers.

I am running it on windows 10 which isn't ideal.

I have 4GB of RAM on the laptop.

I have also set the following in my batch file:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_HEAP_SIZE 100

Is there anything else I could possibly do to fix it?

would downgrading to Windows 7 help or adding more RAM to my Laptop?
