My biggest advantage is that where I live the temperature is currently -5 to 0c so running a Saturn in the garage at 231 with everything else at default is not a big risk in my opinion.

Temp of the hardware is 60-62c during day and in the mid 50's at night

I will surely back down from 231 when the weather starts warming up

My best result is with a Jupiter running at 641GH/s with 0.58% HW.
Using 211.
Highest temps are the 2 chips at the back: around 70 during the day.

I can probably push it more.

Just jumped upto 231 myself...put copper heatsinks on vrms and removed pci extenders cause i was only getting 11.5v on one module and the extenders were getting very hot...running great now 12v-11.9v on all modules now, temps are 64, 57, 53, 52 with 2 fans on rear modules...around 55-56a per vrm and getting around .8% hw errors...up .4% from 211 but i suppose i could push alittle more volts and lower it and getting around 660-680 poolside on eligius Smiley ty ty maybe i'll make ROI outta this machine yet...7 btc more n its party time!!

Great point about the PCI extenders, I need to take a look at that as well since my back modules seem to be running 11.6-.7.. Given your experience any recommendations on how to run the cables, or did you manage to find a power supply with long enough PCIe power cables?

Just take the lid off. Easier routing and better temps as well.

Tired of substandard power distribution in your ASIC setup???   Chris' Custom Cablez will get you sorted out right!  No job too hard so PM me for a quote

Here start with this:


DISCLAIMER: Not my fault if you blow it up! Smiley


Ok first make sure your Miner is updated with the .99 Firmware (tuning)

Then with Putty SSH into your miner

login with your root ID
and your password

type:

screen -r

You will see cgminer running.

Hit Q to stop cgminer

then type this at the command prompt:

vi /etc/init.d/cgminer.sh

Use the cursor keys on your keyboard to scroll down till you see this code:

Look for the line that says:

cmd=$(printf "0x86,0x%02X,0x01,0xF1" $c) 


NOTE: some of the characters at the end (especially the F1) may be different.

The key is the line with the 0x86, when you see that you are on the right line.


change this:

cmd=$(printf "0x86,0x%02X,0x01,0xF1" $c)

to this:


cmd=$(printf "0x86,0x%02X,0x02,0x11" $c)



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


relaunch cgminer with the command line:


/etc/init.d/cgminer.sh restart


You should then see cgminer and you should be hashing between 150-154 per module. (Saturn should be 300-310GH)



NOTE:
If you don't know how to use VI then you can screw things up

here is a shortcut,
when you move the cursor over the 1 in "0x01" that you want to change to a 2, do this:
hit r
then hit 2

and it should Replace the 1 with a 2
then do the same with the F
hit r
then hit 1

then hit:
esc
:
q

ya what cablez said, but i do have a psu that has long pcie cables...and update on hashrate...eligius 12hr rate says 673gh/s Cheesy and my cgminer says 674...that is pretty darn close Smiley

My dead die0 Mercury tanked when it got -30F here,
so I tried the overclock procedure, and surprisingly
it works but only when I keep it heated up to 88-90C.
Hells yeah, better late than never. Its going 159.8GH consistently.

THANKS to ALL who posted here and helped make it happen, I appreciate it. Smiley

Hi, I'm able to change the string where it appears 0x86, but I can not understand the next part. If I press the "esc" key on the keyboard, nothing happens. Excuse me but I'm a beginner. How do I exit and save after making the change?

So to answer the earlier guys question if 211 is: cmd=$(printf "0x86,0x%02X,0x02,0x11" $c)

Would 231 be?: cmd=$(printf "0x86,0x%02X,0x02,0x31" $c)
