After setting 2: Try restarting the miner from the pools menu by just hitting the submit button without changing anything.

Also I think if you get the extranonce working it changes the version of cgminer that is running to 4.8.0 which you can check from the main page.

I've tried restarts (and reboots), with and without changes - but just again now to be certain.  No change.  I am cgminer 4.7.0 across the board.
..and now, after some pool mods and subsequent restarts, I have 3 miners at 4.8.0, flag 2 - but still no ex sub.

Make sure you're pool is formated this way: stratum.westhash.com:3334#xnsub
I tested exactly like that, it doesnt work.

Hrm.  That's frustrating, to be sure.  I've got it working on the latest firmware with both the included cgminer as well as the updated binary.  I wonder if it's the difference in network topology, although I would find it far-fetched myself.

I'll ponder it.

In the mean time, what variables are you passing in the password?  I pass price and difficulty.  I also tack on %h to the end of my payment address to help identify the units.

It's working ... it's working!!  Had a few minutes today to test.  I was always assigning price in the password field, but I wasn't using #xnsub at the end of the ULR.  When I added #xnsub and, for good measure, the difficulty to the password field  - it started working. (this with the price set artificially low to test live)  I've since removed the difficulty, and all is well—on the 4.8.0 miners.  On the 4.7.0's, #xnsub kills 'em (dead).  Now working to get my 4.7's to 4.8's...  Thank you!

oh so 4.8 is required? psh... need a firmware upgrade =/ or howto on changing lol

Hey what's the best underclocking W/GH that was achieved? What start voltage?

Mining Rate: 770.07Ghs
Temp Front / Back T,B    14 °C / 29,28 °C
Fan Speed    40
Start Voltage    0.58 / 0.58 / 0.58 / 0.58
Max Voltage    0.6
Wall wattage 380

It's clingy if you want to go lower!

I dont know the best, but I am running @ less than 650watts

getting Mining Rate: 1221.69Ghs
Code:
Start Voltage
    0.63 / 0.63 / 0.63 / 0.63
Max Voltage
    0.661
Max Watts
    165 / 165 / 165 / 165

edit: btw, the start voltage is not that important.. it is the max settings that count

I believe you! I've seen 2800w out of it!
But it is not normal, i mean i put today 2 sp20 setted at 240w all 6pins. In 3hours because of high load and not good ventilation it cut off thermally! Grin

You can already run 2 at full speed off the DPS2000, have clocked that PSU up to almost 2500w without issues.

some SP20 pr0n for you:

>snip image<

got an EVGA 1600w PSU sitting at home waiting to plug in - I think I'll need another PSU of not massive wattage to get all 4 going Smiley

It has 14 PCIe plugs, right? So, you need just another PSU with at least two plugs, but i would just get EVGA 1300; this way you can downclock to ~700W/1250-1270Gh.
However, if you want to downclock, the trick would be how to downclock them with just one or two PSU.
You would have to do it one by one, bring to stable hash, then switch off and do another.

what is to the left of them-it looks interesting.

Just checked on mine, the extranonce binary is there as /usr/local/bin/cgminer-extranonce (4.8.0)

And there is a link from /usr/local/bin/cgminer to /etc/bin/cgminer which is the binary for the normal non-extranonce binary (4.7.0)

But setting the flags doesn't change anything, i assume it should change the link it to point /usr/local/bin/cgminer to /usr/local/bin/cgminer-extranonce

I'll try on mine in a sec but this is what Zvi said:

Hello,
I've got eight of the SP20 now.
They all have fw version 2.5.64,
my first 6 have cgminer 4.8.0,
but my latest two that i got from the group buy have cgminer 4.7.0.

reasons?
concerns?

(i tried searching back through the thread but i didn't find anything)

cgminer 4.8.0 means most probably that you set the "flag" in the advanced settings that allow extranonce version for nicehash.
