I'm doing it right now with cpuminer

And this is relevant how? 

Are you really that daft? 

Yes. Please explain. With pictures if you can.

sure!

Ready set go.

Does it count if it requires soldering and maybe replacing a resistor?

Depends on how much it can be overclocked

Cool! I'm doing it right now with cpuminer for SCRYPT only.
900MHz for several minutes. Excellent!

I'm really that daft - how does an OC on CPUMiner generalise to an OC on cgminer?

"generalise"? First the spelling is 'generalize'. Secondly, it's the wrong word to use here.
You mean 'relate'!

Your query is moot. Obviously it's not what he asked for, but it's still worth mentioning. Uh, get it?

No, I don't get it. Do the concepts and methods that allows one to OC cpuminer generalise to cgminer? Or not?

You should really keep that spelling and grammar "corrections" shit to yourself. This isn't a grammar forum.

Perhaps I misunderstood your query. There is a special OC version of cpuminer available. http://cryptomining-blog.com/?s=over+clock+gc3355
Sorry for the misunderstanding, if so....

Currently, cgminer/bfgminer supports overclocking but 850 is as high as you can overclock without additional hardware errors and/or additional rejects from the pool. 850 is what everyone is using that has these chips so i'm offering a bounty for the first person to overclock beyond this point.

anyone going to get the bounty?

I'm running 19 miners currently on the Pi and it has not had any stability issues. As you can see in the screenshot below, system load is under 0.1, cgminer processes are mostly sleeping. Some differences from your setup: 1) I'm using scripta and a precompiled cgminer posted by someone initially on litecointalk; 2) I'm running two separate cgminer instances (10 and 9 miners). I would suggest for you to try the precompiled cgminer and see if that performs better. If that doesn't help I would start narrowing the problem by disconnecting half of your miners to see if there is one malfunctioning device that might be causing cgminer to misbehave.

Well it completely stopped so I switched back to Ubuntu server on the Thinkpad for now.

Will try again over the weekend but if it hashes less and produces more errors it's gone. Just communicating my results so far.

This graph shows that it hashes slower and the point where it died (12PM) before I switched back to the Thinkpad.

Looks like people are reporting freezes with the Pi here:
https://litecointalk.org/index.php?topic=9908.225

I should mention that this second "fix" was already applied before I tried to use cgminer for the first time on Pi:

Code:

sudo apt-get install rpi-update
sudo BRANCH=next rpi-update

Not sure if I will waste too much more time on the Pi...would be nice though. I believe that other are having success so it's almost a challenge...but not quite

For reference here is my commands in full (after the initial menu config):

Code:

sudo apt-get update
sudo apt-get upgrade

sudo apt-get install rpi-update
sudo BRANCH=next rpi-update

sudo nano /boot/cmdline.txt
    >slub_debug=FP
sudo reboot

sudo apt-get install screen
sudo apt-get install build-essential autoconf automake pkg-config libtool libcurl4-openssl-dev libncurses5-dev libudev-dev
sudo git clone git://github.com/dtbartle/cgminer-gc3355.git
cd cgminer-gc3355
sudo CFLAGS="-O2 -Wall" ./configure --enable-scrypt --enable-gridseed
sudo make

cd ~
screen -S m
cd cgminer-gc3355
sudo ./cgminer --scrypt -o stratum+tcp://pool -u user -p x --gridseed-options=baud=115200,freq=850,chips=5 --hotplug 0

Stock Raspbian Wheezy (2014-01-07-wheezy-raspbian.zip).
Not too hip on using a pre-compiled executable but I may give that a shot before returning the Pi (https://db.tt/UygLkqwd). Kinda a deal breaker though since I don't want to wait for compiled versions to be released when new changes are made to the source.

I've ran mine at 900 for about 8 hours scrypt mining. I restarted a few hours ago to test 950 but it seemed like I was getting a couple of HW errors every few minutes then so I switched it back to 900. At 950 you can break 400 kh but I don't think that's enough to counteract the increased hardware errors.

At 900 it seems you get anywhere from 0 to 2 HW errors per hour. Also, with cgminer the WU is reported incorrectly. You'll see something ridiculously low (like less than 1/m), but the shares are being submitted correctly (verified on the pool website).

Absolutely no heat issues. PLan to keep my drinks cool with this thing in the summer. Running on an old 12v 3 amp power supply I had lying around.

 I restarted about a couple hours ago, so here's a snapshot since then:
