How to run prime 95/Orthos on all 4 cores?

Title says it all I guess...

How do I run Prime 95 or Orthos on all 4 cores? Still haven't figured it out...

Thanks

With Prime just run the small fft test, it will automatically stress all 4 cores. If you use Orthos you have to run 2 instances.

Okay. Thanks gibson. How do I go about running two instances? Seems too simple to just open two orthos...

I personally have never done it, I always use Prime, it's alot easier. I believe you run the first instance and set the affinity to cores 1 and 2. Then you start another instance and set the affinity to cores 3 and 4. I believe thats how it's done. Like I said, easier if you use Prime.

I like orthos more simply because it's easier to tell how long it's been running. So here it is:
How to run Orthos on all 4 cores.
First, call up 2 different windows of Orthos.
Then call up the task manager(ctrl,alt,delete)
In the processes tab RIGHT click on 1 instance of Orthos and click set affininy. Uncheck 0 and 1 and click OK.
Then RIGHT click on the other instance of Orthos and click set affinity. Uncheck 2 and 3 and click OK.
Now fire up orthos and watch those temps rise.
