btw i noe y bigdawgfox has so many WUs he went to his school..

Wrong, if that was the case, it would be saying more than just 1 active processor in Bigdawg's profile.

He has so many WU's because he overclocked unstably, and was bouncing WU's instead of completing them, they finish one frame, and fail and send in the work to the server, this, a WU is done, but no points are recieved, and a new WU is downloaded.
 
It was just a thought.

What sort of crash is it? BSOD, reboot or just freeze?

I used to find that my system would just freeze when running F@H, until I raised Vcore. Other than that it was usually alright, except if it got fairly hot after about an hour of game playing, and then the same thing would happen. Cured that problem too.
 
I'm sure theres an easier way to explain this prog. :blink:

To much abracadabra in this thread to me. Thanks to Slinger i had it working in a few minutes, while reading this thread only gave my headaches.

You have got to remember that theres a lot of foreign non geeks on this board who would like to contribute as well.

Just my 2 cents :)

Freeze in both F@H cases. It was frozen from when I left uni until I got home (I was checking the PC using VNC in uni)

I don't really want to up the Vcore, running 46 degrees c at full load at the moment (Athlon 2700+, aluminium HS), I might give it a try if I get more instability problems though, cheers :)
 
Just to show you what we're doing is child's play. :unsure:

It makes me humble.
Over at Sudhian.com a guy named MarkF build a 'Folding Farm'.
A rack totally filled with stripped boards, with a single goal: Folding.
Every floor in this rack carries 2 boards.

...... and since summerlinda may not be as active they onyl have 3 days worth of data?........

Not as active?
Man, I'm folding like crazy, 24/7, I need a break, its exhausting ;)
 
You've only got one processor, but some parts of it are duplicated. These are the simpler components which don't produce much heat, such as the main instruction path, the arithmetic unit etc.

It has to report that it has 2 processors so that windows can schedule it to execute 2 tasks simultaneously. That effectively means that with two tasks which for the most part only use the duplicated parts you can get more performance out of the chip.

Unfortunately F@H mainly uses parts which aren't duplicated - the MME stuff and the FPU. These are complex units and produce large amounts of heat, which is why they aren't duplicated. So although you could have 2 copies of the program scheduled to run, in practice they would be waiting for the shared resources to be free.

There's even a down side to HT when you want to run another program, even with only one copy running. Windows sees that it has a spare "processor" which can run your prog, it doesn't know about the shared resources. So windows schedules your prog and doesn't bother interrupting the other FPU/MME intensive prog. If your prog uses the duplicated parts there's no problem, but if it uses the shared parts then it runs like a dog.

Nice one Intel - how to slow down our systems by not thinking out the problem. Nothing new there then. :dry:
 
Ive joined and now working under the name TRshady :)

Proud to be able to help ... though I really dont see how this works ...

Have a 1.5ghz comp running ..... 24/7 :D
