I tried running Orthos twice, it kept stressing the same two cores. Can I get a link to prime95, I googled it and got pictures of multiple different programs.
First call up 2 windows of orthos, call up task manager(ctrl,alt,delete), under the processes tab find the 2 different instances of Orthos. RIGHT click the first one and click set affinity, uncheck 0 and 1 and click O.K.
Then RIGHT click the other one click set affinity uncheck 2 and 3 and click o.k.
Then start them up.
I like Orthos better because it's easier to see how long it has been stressing.
