Prime95 and setting affinity

[glitch]

When you set the processor affinity in Prime95 for a dual-core chip, do you have to also set the affinity in Task Manager?

Because I'm running two instances of Prime95, both set to seperate cores, but Task Manager doesn't show them as being set to a particular core...

Which is right? Should I manually change this in Task Manager?

I've seen screenshots of that on the forum - always wondered what it was.

Thanks for the tip, Arthalen.
