Ubuntu Claymore's zcash CPU mining CPU not pegging to 100%

I tried replying to a similar old topic as this is close to that one ... however since I don't know how this all works, I have not seen a reply ... so I created a new topic .. please let me know the best way to do this in the future if I have done something wrong.

I'm new to mining .. I am using Claymore's CPU ... on Ubuntu ... I have used 1,2 and How to Mine Zcash Part 3 - mineZcash ....

I have one rig working fine as the CPU pegs to 100% and stays there ....

My other rig is setup the same way ... but it does not peg the CPU to 100% ... I have used the test tool - ./qa/zcash/full-test-suite.sh and have not found any problems.

Is there anything else that I missed, or could test, or show you guys how my rig is setup .... ??

I stopped my rig, changed .conf parameter to gen=0 and started the rig again ... waited about 10 minutes, the CPU never went above 2% ... stopped my rig, changed .conf parameter to gen=1 ... and the CPU still does not go above 2%.
Any other ideas?
