The Intel Pentium D had two versions that run at 2.80 GHz. Both are double core CPUs.
If you press CTRL-ALT-DELETE the task manager pops up. The second tab is "Processes". Look for the process called "F@HCore_xx.exe". (xx=78 or 82 in most cases).
If you have one F@H running on a single core you will see CPU Utilization = 100% (or close)
If you have one F@H running on a dual core you will see CPU Utilization = 50% ( or close)
Follow these instructions from another thread and you will have two instances of F@H running, maximizing your points potential.
Download the FAH No-Nonsense Text Only Console 5.04 from Stanford downloads here:
http://folding.stanford.edu/download.html Save it to a download directory or your desktop. DO NOT RUN IT FROM THIS LOCATION.
Make a new folder somewhere safe, such as Program Files. Call it F@H1.
Make a second folder somewhere safe, such as Program Files again. Call it F@H2.
COPY F@H504-Console.exe into the F@H1 directory.
CUT and paste the F@H504-Console.exe into the F@H2 directory.
Enter the F@H1 directory. Run F@H5.04-Console.exe. Enter all the normal stuff (Team 36120, Private_Sector_Does_It_Better, etc). When it asks to "Set Advanced Methods" enter "y".
The Advanced Settings need to have "Run as a Service" = y, and the machine ID needs to be '1' and '2' respectively so the Stanford servers can tell the work units apart.
If in doubt, edit the "client.cfg" file. Make sure that your name and team number are correct, and that each client.cfg has either a '1' or a '2'.
Thank you very much for working through the setup issues.
