nah, it's not. this rig has been running F@H for over a year now before i followed Maximum PC's guide and changed to 3.25 with the -forceasm switch
well, lost about 48 hours........(my computer is on for 18 hours a day, excluding games)
slow and steady wins the race

Hmm, I don't think I've been having problems on my unoverclocked 1700+ tbred-b (will have to go check the logs in a second). That sucks to loose so much work, though. :(

Been running F@H on my OC'ed XP1600+ @ 1.75Ghz with -forceasm with no problems.

I got that once after my system hang/freeze and restart itself. It start new project after Checksums don't match error. This does not happen a lot, it just a fluke or once a life time unlike unit-end-early error, I guess. BTW my system is P4 not AMD, so this might have nothing to do wite SSE+

Note: you should check if your system often has problems with this particular protein. Mine, quite often has problem with P340 and still don't know why. Maybe it doesn't like my overclocking system :(
