BFGminer high cpu usage.

[helipotte]

Anyone had any problems with BFGminer and high cpu usage in Windows 7 X64.  I am only using monarchs.  Seems like the more cards I add, the higher the

usage.  The system has a modern Intel cpu and is dedicated to coin mining, 16 monarchs connected using Bfgminer 5.3.0.

Thanks!

check to see what else is running.

use system monitor.

once in a while i would do a restart and i would end up having two bfgMiners running this was casuing too much cpu.

so check to see that.

Thanks for the suggestions.

check to see what else is running.  Done this.   

use system monitor.  Done this.  Just BFGminer using cpu cycles.

so check to see that. Not this either, but have encountered this in the past.

The problem does seem to "scale" with the number of units I have connected.  One or two units is no problem.  Now with 16 units cpu usage hovers around 60%.

BFGminer also shows this behavior on my beaglebone black running Minera.

Even tried CGminer.  All of the units show up and hash but at about 25% of their normal rate.  This seems to be a bug in firmware 1.4.5.  My other units

with older firmware don't do this.  They have 1.4.2 and 1.4.3 and work great with CGminer.  This behavior also is present on the beaglebone.

I seem to remember an issue like this when I had about 100 block erupters and tried to use BFGminer.  Hmm.

Just to recap on my situation:

-This is a "dedicated to coin mining" computer.  No firewall/antivirus/other programs running/or even updates.  Has a modern CPU/motherboard.

-I also have a beaglebone running Minera 0.6.1 and when I connect all of the monarchs to it and run BFGminer, cpu usage is also very high.

-I can't use CGminer with these units due to performance.  Suspect it is a problem with the firmware they have.  Don't know if anyone else has had this problem.

-Just for info, I have tried different hubs and had the exact same outcome.  Currently using a Block erupter 49 port.
