Try to use -t 4 param. I have i7-4720HQ and 16Gb RAM, which mines at about 150-200 and goes down to 110-120 when I use my computer for work (business needs, not heavy load like 3d rendering or so). So your speed is abnormal.
35-50H/s is ok for old i5-3xxx but not for your CPU
Thanks for the advise. I am running it on 4 threads already and its not helping any. Tried to add -t 4 and the speed is still down.
1. Are you getting "FAST MODE ENABLED!" during miner start?
2. Does your CPU start mining with initialy low spped (see number 1)?
3. Does your CPU start mining woth normal speed and then drop down? In this case it could be kind of CPU power or thermal limitation (according to CPU model you try to mine at notebook). Check you windows power-performance settings etc.
