So I have an I5 3570k (Overclocked to 4.4 GHZ)
32gb 1400mhz ddr3 ram (Possibly only 1333, but it should all be matching modules)

and for whatever reason, I can only mine 80-100 h/s

For comparison, I also have an i5 2500k running at 3.4GHZ that is getting 180-200
16gb 1600mhz ddr3


It's not thermals (I'm at about 60C on hottest core)
and task manager says its getting about 80% of the CPU (roughly the same % on both computers)
Win 10 with winMiner

I was just curious if anyone might be able to narrow down the root cause of this slowdown. I'm not looking for a lecture on the unprofitability of CPU mining (I don't intend to mine with them, I just got winMiner and thought I would try it out for curiosity)
