F@H and Freezing Computers

I got up this morning, hoping to find my my third WU completed. It was a big one -- I had spent 3+ days on it.

I turn my monitor on, fire up the F@H log file, and am treated with this sight:

[03:43:35] Preparing to commence simulation
[03:43:35] - Ensuring status. Please wait.
[03:43:51] - Looking at optimizations...
[03:43:51] - Working with standard loops on this execution.
[03:43:51] - Previous termination of core was improper.
[03:43:51] - Files status OK
[03:43:52] - Expanded 352404 -> 1770005 (decompressed 502.2 percent)
[03:43:53] - Checksums don't match (work/wudata_03.xtc)
[03:43:53] - Starting from initial work packet

OMG. COMPLETING "p1409_polyQ26 in water" would have got me like SEVERAL milestones.

My question is this: does having your comp. freeze always cause F@H to start the WU over?

Because my computer (1ghz athlon 256 ram) freezes quite often...

It can cause that.

Especially if there's any sort of instability, it can interfere with proper writing to the disk.

I have a palomino 1.2ghz that had this problem constantly; sometimes even on a normal reboot. It wans't OC'd but I finally just upped the cpu voltage one notch, and it hasn't happened since (I guess my motherboard didn't supply enough voltage).

Any instability can cause F@H to get screwed up and terminate WUs early, or restart WUs. The suggestion of increasing the voltage slightly (a _very tiny_ amount) is good, but check your cooling first to make sure that filters aren't clogged with dust, fans still work properly, etc.

stratman, sorry about losing all those hours. Same thing has happened to me.

Couple things might help:

A journaling file system. (NTFS or that new Linux fs)

If you have FAT/FAT32 filesystem, look for a way to skip checkdisk on startup.

Use the -forceasm flag so that you don't see: "Working with standard loops on this execution." after a restart.

Thanks :)
