Hi,
a member of our team has this kind of error

<core_client_version>6.3.10</core_client_version>

he is using WinXP32, boinc-version 6.3.10 and the 177.93 driver.
My idea was that his shader clock-rate is to high? or is something else wrong?

This is almost certainly due to instability caused by the high clock rate. The reference 9600GT design specifies a clock of 1625MHz. This user should use the NVidia control panel to reduce the shader clock.

THX, this was also my idea. I will tell him this.
