Project: 780 and 785 - super low PPD

Hello.
I'm folding these two projects on Linux on my core2duo E6300 system. Is it possible that this frame time I'm getting (1h 40 min) is right? It gives me like super low PPD of about 80 PPD? This box can do much more for sure.
What is wrong here? Benchmarking, my box, something else?
Project: 780 (R3, C53, G1)
Project: 785 (R5, C97, G2)

This Gromacs 33 core must have some problem with proper detection of SSE and 3DNow instruction set on my system. (Core2Duo E6600) I have to use -forceasm flag. After that the frame time is 100% shorter.
Now I have 50 minutes time for 1 % (before 100 minutes).
Is there anyone else folding this projects?

Arguments: -forceasm
Warning:
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.

How do you quit your client ?
These message indicates that you're not doing it correctly :

This time I quit with ctrl-C from console, because I want to show the difference in log with or without using -forceasm.
What is the proper way of quiting, anyway?

CTRL-C is the best one indeed. By the way, -forceasm is the best way to be sure that your client will always use optimizations (if your machine is stable, you can use it safely).
