I keep getting these errors when running the Claymore Ethereum mining app.

EthDcrMiner64.exe -ewal 0x2609B752a84Fxxx0d10c40Fe20A/worker01/midxxxeer@thexxxide.com -epsw x -etht 1000 -mode 1 -ftime 1 -gser 2

ETH: 2 pools are specified Main Ethereum pool is

Driver 368.81 is recommended for best performance and compatibility Be
careful with overclocking, use default clocks for first tests Press
"s" for current statistics, "0".."9" to turn on/off cards, "r" to

Setting DAG epoch #98 for GPU #1 
GPU 1, CUDA error 11 - cannot write buffer for DAG 
Setting DAG epoch #98 for GPU #0 
GPU 0, CUDA error 11 - cannot write buffer for DAG

Here are my variables:

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

cannot allocate big buffer for DAG.

Your card is likely not to have enough memory for the DAG see this post.

And more explanation about DAG concerns.
