program to stress 4 cores?

XD

Prime95 has been around a lot longer.
(Orthos uses the prime engine)

Anyway - For Prime, copy & paste the extracted folder 3 times.
So you have 4 different Exe's to prime 95.

Then run each one and set it's affinity.

Then you have one running per core and they save their settings so you can have folder names of "Prime 0", "Prime 1" etc :)

I did until a new version of Prime95 came out :)

The link I posted includes a download link for the latest version of Prime95 which supports dual and quad cores meaning you don't have to run two or more instances of the same program :)

don't have to do this anymore! :)
 
orthos beta stresses 2 cores. i assume u can run 2 instances of that. For Prime95, you don't need to copy the whole folder, you launch a second instance with the -A1 parameter.. and a 3rd and 4th, but i don't know how that parameter changes for more than 1 "assisting" instance, read the prime95 docs.

(make a shortcut and stick that on so u dont have to do command line every time.. or do a batch, but i cant remember how to run several things from 1 batch file without it waiting for one to close before starting the next.. too much time on linux has made me a DOS noob)

Then when u have enoguh instances open, set the affinity in each copy to each core. each instance will keep its own settings if its launched with the right command line parameters.
 
Once it is stable enough to pass Prime or Orthos you might wish to try the Windows SMP client for Folding@Home. It will stretch the system to its furthest using highly optimized SSE/2/3 floats using four simultaneous processes. Many systems are stable enough for Prime but are still too unstable for FAH. If FAH can complete a work unit without failure, which takes about 20 hours on a fast C2Q, it is certainly stable.
