Here's mine at 54 bits on a usb lightning bolt plug:



52 bits yielded about 2.2gh.

Why such an old version of cgminer?  I am using 4.9.0 with a cryptorig HH and an antminer U3.  To OC the hitchhiker you need a powered usb strip (would one of the new usb ports with a lightning bolt work too, maybe?) and a fan cuz that sucker is gonna get hot.  I have a small fan on mine even at stock settings. --nfu-bits 50 should be the right option for current version cgminer, and change the 50 as mentioned, use that in your batch file.  Your batch file should look like:

Code:
cgminer.exe -o pooladdress -u username -p password --nfu-bits 50

or enter that at the command line in the cgminer directory.  I haven't tried overclocking yet because I don't have a powered USB strip, but from what I can tell from the readme's that should be the right command, at least it's what I plan to do when I get the power strip this weekend.  It runs about 1.9-2.0gh for me stock 50 bits.

Those commands are not for the official cgminer but some dead branch long since abandoned. Grab the latest cgminer and read the extensive documentation included about various bitfury asic usb sticks which yours appears to be one of.

I picked up a Cryptorig Hitchhiker usb stick miner and got it to run on cgminer by running the cgminer.exe and then entering all my pool info at the prompts given (Cgminer 4.2.0). It's humming along smoothly at about 1.8 to 2.2 gh/s and showing up on my pool, but I want to overclock it a little. The guy that I bought it from offered a sample command line to get it running and explained which number to change to overclock it.

"Sample command line: cgminer.exe -o stratum+tcp://stratum.bitcoin.cz:3333 -u workerusername -p workerpassword -S all --set-device NFY:osc6_bits=50
The last number can be used to over/underclock the miner. 50 is stock, 52-54 usually works."

The problem is, I can't figure out how or where to enter this command line. I wrote it to a batch file but when I run that, it just pops up a shell for a second and closes immediately. I tried running the command line from the windows command prompt and I keep getting "this is not a valid cgminer command" error messages.

So then I tried bfgminer, which keeps saying "No devices found."

It seems like I'm just missing some simple, fundamental step that everyone seems to know about but me. Every piece of information I've been able to find on this subject jumps straight into which commands to enter. Where the heck do I enter the commands??? I'm at my wit's end with it. Any help is GREATLY appreciated.

Thanks!
