Might as well try at a lower memclock and work us upward, try changing it to:
"
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECT 1
cgminer --scrypt -o stratum+tcp://usa-1.liteguardian.com:3335 -u Sancho.1 -p x --intensity 13

--thread-concurrency 8192 --worksize 256 -d 0,1 -g 2 --gpu-memclock 1210
