If you only use deep versions, then both graphs should be up.
In a single version, only one graph should be fully up.
Go to engine-parameters to change the numbers of threads (cpu) it uses.
Try Deep Shredder, go to parameters and change nr. threads to 1.
Let it ponder and it should use only one cpu (graph) fully.
If it does not then there is something wrong..
Deep Fritz, junior etc. should use all logical cpu's.
This has nothing to do with affinity (if you don't change it) and certainly not
with oc'ing.
