6990 is dual-chip card. previously it was working to crunch on both chips, now it uses only 1 even tho boinc sees both.

rebooted etc no change. now I'm stumped.

Finally figured this out, setting it to crunch 8 WU was simply too much and caused weird issues. 4 or max 5 per GPU seems to be the best number for me.
