If you forgot the -smp switch, Ctrl-C to stop work and relaunch the folding client with the "-oneunit" switch to resume work (but don't put the -smp switch in yet) and finish the current unit. Then you relaunch with the -smp switch (or you can then use the -configonly option to add -smp in the "additional client parameters" question).I installed the DEINO beta SMP client and fahmon 2.3.4 is reporting 547.41ppd for project 2484.

Ragnar Dan wrote:I didn't mean to reconfig while the client was running. Just to leave the old WU in there and change the command line parameters before it's completed. I expect it would just let it finish and then only download SMP WU's, though as mentioned I've never tried it.

A bit unrelated. Anybody use the new ATI drivers that have a performance boost for F@H?

I've written about the ATI side of GPU optimization a few times here.
I'll confirm that ATI clients only boost when the Core clock speed is increased (No shader setting on the ATI side). In fact, I've downclocked my memory settings to the lowest CCC allows for the 4870, 475 Mhz instead of 950 Mhz, and not a single drop in output. Of course that's probably GDDR5 working its magic and I haven't gotten anyone else to confirm this for cards not using GDDR5.
Actually, decreasing the memory speed usually allows you to hit higher stable core clock speeds. I squeezed an extra 15 MHz out of the GPU (Around 100 ppd) by lowering memory speeds, which would normally give artifacts and unstable machine errors if I tried to run at that speed with the memory speeds at stock.

Launch directory: C:\FAH
Arguments: -smp -deino -verbosity 9 -forceasm
By using the -forceasm flag, you are overriding
safeguards in the program. If you did not intend to
do this, please restart the program without -forceasm.
If work units are not completing fully (and particularly
if your machine is overclocked), then please discontinue
use of the flag.

Any ideas? Then it just keeps downloaded the core A1 again, and again.

They are different downloads too so they are quite different.I've never seen the -deino flag. Are you sure that's a flag? Try running with -smp and take -deino out.
