streams sdk 1.2.1 beta x64
vista x64 sp1 6GB Q6600 ATI 3870
Windows Vista TDR turned off via TdrLevel=0 reg key
simple_matmult -t -x 5120 -y 5120 -i 1
runs fine when CCC is not open, windows can not move for a while but mouse move ok.
When CCC is run in advanced mode, I put it on ATI Overdrive Tab to check temperature, then run simple_matmult -t -x 5120 -y 5120 -i 1 the machine will freeze.
tested with CCC 8.9 and 8.11
