is it normal that my board #62-0017 makes a high frequency sound when hashing with glasswalker or makomk bitstreams?
I wonder what I can do to get the good results like e.g. toxicocean. Any tips?
I have the high frequency sound also (but not always, or at least I don't always notice it)
hm, if it helps here's a rundown how I program and run mine (#0005) - I assume the controller version is already v1.3, and the drivers are already installed on your programming/mining pc:
- start the enterpoint virtualbox on my pc (I use Windows 7, 64bit)
- set the correct switches on the cairnsmore for programming (at this point the cm is completely off: not powered, and not connected through USB)
(switches depending on your bitstream, but for the Makomk bitstreams: SW1: 3 off, others on; SW6: 1 off, others on; SW2/SW5: all on; SW3/SW4: 2 off, others on)
- login to the enterpoint virtualbox (root/password)
- power on the cm1 (power only), and wait for about 3 minutes
- connect the cm1 with usb cable to pc
- verify xc3sprog can connect to the cm: xc3sprog -c cm1 -j
- if ok, continue, otherwise start over again from beginning (better to disconnect the cm and reboot the pc at that point to be absolutly sure)
- program the bitstream:
xc3sprog -c cm1 -p0 -Ixc6lx150.bit shortfin_icarus_cm1_test_190_overclock.bit
xc3sprog -c cm1 -p1 -Ixc6lx150.bit shortfin_icarus_cm1_test_190_overclock.bit
xc3sprog -c cm1 -p2 -Ixc6lx150.bit shortfin_icarus_cm1_test_190_overclock.bit
xc3sprog -c cm1 -p3 -Ixc6lx150.bit shortfin_icarus_cm1_test_190_overclock.bit
each command will take some time, haven't checked but I guess around 10 minutes
- if all commands went ok ("Verify: Success!"), power off the cm1, and disconnect USB cable
- set the switches for mining: SW1: 3 on (others stay as they are)
- boot your mining pc/pi/whatever (if you use the programming pc also for mining, reboot it first!)
- power on the cm1 (power only), and wait for about 3 minutes (leds will be blue at the start, and will all turn to orange after some time)
- connect the cm1 with usb cable to pc
- start cgminer (any new version)
Linux: cgminer --quiet --disable-gpu -S /dev/ttyUSB0 -S /dev/ttyUSB1 -S /dev/ttyUSB2 -S /dev/ttyUSB3 -o http://<url>:<port> -O <username>:<pw>
Windows: cgminer --disable-gpu -S \\.\COM21 -S \\.\COM23 -o http://<url>:<port> -O <username>:<pw>
(Starting it like that on Linux will give a warning message that 2 of the devices couldn't be opened, but it will start on the other 2,
on Windows you can also specify \\.\COM20 and \\.\COM22 if the 21 and 23 don't work)
- cm1 should now be mining (leds shouldn't be constantly orange anymore) - let it mine for 48 hours to have stable statistics (MH and U values)
some additional info: I don't use any USB hubs, I just connect straight to my pc; except for mining on my Raspberry Pi, for which I use an unpowered USB hub. To make it work I need to boot the Pi first, enable the ftdi driver (execute with root: modprobe ftdi_sio product=0x8350 vendor=0x0403), connect the unpowered hub first, then connect the c1m to the hub, and then mine.
dunno if this helps...
