when setting up my cgminer/ linux raspberry pi , I changed frequency to 75 (1st time I started to use my 2PAC, as did not have a fan). It now seems stuck on 75 frequency (a bit low). In terminal I put in start up command and added 100 at end to change frequency : cgminer starts , says working at 100, but then says changing to 75 (again). I can't find the config file (I assume this is where I would have to change). Thanks for your help. NB I am just starting in mining and have limited linux knowledge.
indeed Sidehack,
I think my 2A phone charger power supply ain't stable enough but it's hard to find powered hubs in Belgium that deliver full power to each port and not the standard 0.5A.
I went back to 150MHz as I figured out this night that it stopped mining again after a while and I could not get it working again at 200, 180 either as it stopped after seconds/minutes again.
Now it worked fine through the night at 150.
this is my current stats
0: BSD 10015542: BM1384:2 150.00MHz HW:0 | 21.28G / 16.36Gh/s WU:228.5/m
Thanks for adding the leds, it's not only cool looking but it notifies me when something is wrong if it doesn't flash after a few seconds.
