I second that. I'm getting between 575 and 625 on my day 1 shipment miner (which arrived on day 5) . The Beaglebone board went south on mine the second week I had it and I lost 2 weeks due to incompetence by KNC. This is truly amazing and I thank you so very much for sharing the info. Still wish I had my 2 weeks back when the difficulty was still 86,933,018, but this takes a little pain away from the wound and I salute you for it. Curious if any of you guys bit on the new miner? If so I look forward to seeing what you can accomplish. I didn't bite on that one myself after getting burned the first time... but will be watching. Many thanks!

- .m.w. -

and all you did was issue this:

sed sBD1BF1B /config/zzz.sh ; /config/zzz.sh restart

??

The sed command changes one register and gives you a mild 7% boost in speed. In order to see the fastest speeds you need to read though the hieroglyphics on this thread and figure out what they are saying. when I figured it out, I am getting almost 15% over factory speeds.

The main thing you need to do is ssh into your miner and use a text editor to edit /etc/init.d/cgminer.sh

try:
vi /etc/init.d/cgminer.sh

Use the cursor keys on your keyboard to scroll down till you see this code, the important parts you will change are in bold:

Quote

   if [ $p -eq 2 ]
   then
   cmd=$(printf "0x86,0x%02X,0x01,0xF1" $c)
   if [ $c -eq 1 ]
   then
   cmd=$(printf "0x86,0x%02X,0x03,0xE2" $c)
   fi

When you see someone say "Try 201" (which gives about 12% speed increase) you would edit the code to look like:

Quote

   if [ $p -eq 2 ]
   then
   cmd=$(printf "0x86,0x%02X,0x02,0x01" $c)
   if [ $c -eq 1 ]
   then
   cmd=$(printf "0x86,0x%02X,0x03,0xE2" $c)
   fi

Hit escape when finished. Then hit the : key, then x to save.

relaunch cgminer with the command line:
/etc/init.d/cgminer.sh restart

Don't blame me if shit blows up. I'm just one newbie helping another.

I personally use 211, but have extra fans inside the case for extra cooling, just to be safe. A list of codes and corresponding speeds are listed several times in this thread, I suggest trying several until you find one that gives you a good boost in speed without going over 40-42watts per die, since they are rated at 40W per VRM.

Good luck.

My problem is I cant find that exact code in my file

   # re-enable all cores
   i=0
   while [[ $i -lt 192 ]] ; do
   i2cset -y 2 0x2$p $i 1
   i=$((i+1))
   done
   spi_ena=$(( spi_ena | (1 << $p) ))
   done
   fi
   if [ -n "$bad_ports" ] ; then
   for p in $bad_ports ; do
   # Disable PLL
   i2cset -y 2 0x71 1 $((p+1))
   for c in 0 1 2 3 ; do
   cmd=$(printf "0x84,0x%02X,0,0" $c)
   spi-test -s 50000 -OHC -D /dev/spidev1.0 $cmd >/dev/null
   done

   # disable all cores
   i=0
   while [[ $i -lt 192 ]] ; do
   i2cset -y 2 0x2$p $i 0

Thats what miine looks like (4 VRM)

What should I change? The bolded line?
