Project 6803: (Run 4, Clone 66, Gen 255)

[PS3hep48]

Received this WU about 11 hours ago for the first time. Core consistently shuts down at approximately 1% completion. AMD 3800+ / GTX-460 Rig is stable having processed over 1500 WUs in the last 9 months. Same result at stock speeds or OC'ed. Also, assignment server keeps re-assigning me this unit. Have uninstalled 6.34 client and re-installed and keep getting assigned this unit. Here is a snippet of the latest experience with this WU:

Would appreciate help in getting another WU assigned so I'm not wasting resources. Thanks in advance.

Mod Note: Marked bad 10-29-2011 (This report plus the two in the database makes three.)

[PS3hep48]

Didn't read Troubleshooting 'Bad WUs' topic prior to posting. Followed the instructions for getting a new WU and I'm back up and folding.

Folding with the 266.58 nvidia drivers on WinXP/32-bit, no issues other than the downclocking problem...the GTX-460 would downclock at both stock and OC speeds. Since installing Win7/64-bit with 266.58 drivers on the box about a month ago, the downclocking problem has not surfaced again. My GPU temps are consistently in the mid-50C range while folding.

There are two error reports in the WU Database. It will be marks as a bad one once we receive another bad report.
