Long Work Unit?

OK, so I've got two PCs folding away. One is a P4, which has completed 11 work units. The other is an Athlon 64 2800+ system that hasn't yet managed to complete one. It seems to be chewing away at the WU, but the estiamted completion date is 18 Jan. Would my honorable colleagues (you lot) think that there might be a problem here, or have I just been assigned the mother of all work units? I cetainyl looks like a big ugly protein on the display (I usually leave it running in the background with the display turned off, I hasten to add)...

The working on entry says p1408_Q20X4 in water, and it is on frame 175 of 2500 as I type after about 4 days of folding. Any thoughts?


 
The following link gives you time information and points based on the type of work unit. I would say that in your case, you have a problem. that computer, running 24/7 with little else going on it should only take at few days to complete the project.

You might want to look at your task Manager and see what is sucking up all your cycles.

BTW. Screen savers take up a lot of cycles.

Thanks for the link. That does seem to indicate that the WU I was assigned is one of the biggest, baddest ones out there, with one of the highst credit values in the list. Strrangely enough, Folding@home has now decided that the estimated time to finish is Dec 8th, so I'll jut leave it running and see what happens.

I suppose the moral here is "don't trust estimates made by computers who are no good at estimating things..."


 
Have not done p1408 yet but all the other p14** work units I've done have taken between 55 & 65 hours to finish.
This works out to very close to 100 points per day @ 2.1 Ghz on an AMD MP system.
So at around 2.25 points per hour per Ghz on an AMD64 system it should take 261 / 2.25 / 1.8 = 64.4 hours
So you should finish it in something over two days.

Is somethings sealing your cycles ?
Is F@H setup to use 100% of your cpu's spare cycles ?

Luck.......... :D

2500 is a big work unit. Will take a while.
 
So I did some investigatin' last night and I think I got to the bottom of the problem. I checked the CPU temp and it was runing at a toasty 64 to 65 degrees. So I swapped out the stock heatsink with a Zalman CNPS and the processor temp dropped significantly to 46 to 47 degrees. So I guess it may have just been running too hot, and may have been doing that thermal limiting thing.

The system now seems to be folding nicely and is due to finish the WU tomorrow.
