NEED HELP - big WU, small laptop

Postposted on Thu Jun 26, 2008 2:27 pm

My poor little laptop, he try so so hard. Unfortunately, the Man keeps giving him WUs that will take something like 200 hours to complete. Below is the output of the current run (after a restart). The laptop is a 1.6GHz Turion with 2GB of RAM.

Is this normal? My understanding was that 4 days was pretty much the limit - what can I do to speed this up?

Seems rather slow. The WU you're folding has a time limit of 6 days, but you still aren't going to make that. It wouldn't surprise me if the machine was slowing down the CPU purposely to keep from overheating, but you can verify that with cpu-z.

Project 2665 is a slow WU. :(

Thanks for the tips. I kicked that WU and loaded the single core client. I had no business trying to run SMP on that box - it was just the first try and I didn't know what I was doing, really :oops: . Anyway, thanks again, all better now. :D

I'd probably have tried running a CD with notfred's diskless ISO on it just to get an idea of the speed of the machine, hopefully avoiding any OS-related step-down in speed. But I'm generally in agreement. Laptops are best for short-term use, not running folding applications at maximum CPU speed and heat output.

One major reason I'm not too favorable toward using a laptop is that it makes the batteries go to crap after a while unless you remove them and... do whatever it is that would make them keep working over a long period w/o a charge. If that's even possible. Charge and drain cycles would be too much work to be worth it, from my perspective, and though I can't recall what the lithium ion specifics are, I think all previous technologies have a maximum number of cycles to them.
