Title: The KnC Saturn Miner experience Post by: coda on October 14, 2013, 12:18:07 AM Hello All
I wanted to share my experience with you about The Knc Saturn miner ordered june 4th, payed in the 7 day windows: order 9XX "Day 2": i received it october 11th (officially, "the shipping" started on the 1 st october) First days of october, no change about my order, then for about 4-5 days in had a "in progress status" The 9 th, i received a mail from UPS said that i'll be delivered next day Next day, the 10th, nothing ... and i saw on the tracking that UPS had a problem in sweden or germany (don't remember) and lost one day ... >:( So i got my miner the day after, and plugged it asap with a Corsair AX 860 + kill a watt: 275 GH/s for 450 Watts at the wall ... (slush pool stats) 4 VRM boards and very cool temps, quiet air flow one hard reset done in 24h because the miner seemed idle (seems this happens when i was on the web interface) no problems exepted that manual reboot doesn't worked ... Next day, i went to the web interface to check the firmware, it was 0.91 ! I listened to knC advices, and decided to go for the 0.95: 293 Watts but only 210 GH/s :( manual reboot worked, power usage was reduced, but performances were no here ... Note: When i upgraded to the 0.95 firmware, it was still notified 0.91 on the web interface... I was using safari on mac OSX, but i noticed that using firefox resolved this problem ! So i tried to downgrade to every last firmwares and several hard resets but i doesnt seems to do something (sometimes that was worst: 200GH/s) Until i went to the original 0.9 release, and fucks knows why, i saw on my kill a watt at 450 Watts ! Then i immediately went to 0.91 wich brings me the same perforances than in the beggining and i switched to 0.94, no problems were experienced, but nothing changed from 0.91 ... Finally, i'm here now, trying to acces to cg miner, but i don't know what to do when i'm in the OSX terminal with a SSH connection opened: what magic words do i need to type to enter the cg miner world (i prefer, cg miner, conf files, etc ..., than this limited web interface) laters coda Title: Re: The KnC Saturn Miner experience Post by: Rampion on October 14, 2013, 12:23:45 AM "screen -r" once you have a SSH connection open to your box
Title: Re: The KnC Saturn Miner experience Post by: coda on October 14, 2013, 12:29:37 AM hi Rampion
thanks for your help ! but this doesn't worked, i've already tried it and it says: -bash: sceen -r: command not found Title: Re: The KnC Saturn Miner experience Post by: RoadStress on October 14, 2013, 12:35:48 AM hi Rampion thanks for your help ! but this doesn't worked, i've already tried it and it says: -bash: sceen -r: command not found it's scReen, not sceen and i would recommend you sticking it to 0.95 Title: Re: The KnC Saturn Miner experience Post by: coda on October 14, 2013, 12:43:07 AM sorry i made and error in the message
i really typed "screen -r" in the terminal: new-host:~ xxxxxxxxx$ "screen -r" -bash: screen -r: command not found and without the "...": There is no screen to be resumed. new-host:~ xxxxxxxxx$ excuse me for my zero knowledges in terminal use @ RoadStress: yes i wish to stick to 0.95 but with a lost of 75 GH/s, no way Title: Re: The KnC Saturn Miner experience Post by: billywilly on October 14, 2013, 12:55:56 AM you have to be connected via ssh first to the saturn
"ssh root@yourminerip" will ask you for a password "admin" now you can enter in the terminal "screen -r" all of this supposing that you enabled before SSH at the web interface of saturn. Title: Re: The KnC Saturn Miner experience Post by: coda on October 14, 2013, 01:00:53 AM problem fixed:
SSH connection on the terminal was not configured correctly I'm in cg miner now ! in the terminal: Shell/new distant connection select saturn sever user: root terminal opens password: admin then: screen -r -> cg miner thanks Title: Re: The KnC Saturn Miner experience Post by: warhawk187 on October 14, 2013, 05:59:40 AM Firmware 0.95 made mine stable (cgminer would crash and error out on all the other firmwares after 15-20 minutes), but at the cost of hashrate of 20-30Gh/s.
Does anyone know how to setup a cron job in the config via ssh to restart cgminer every ~30 min, so I can see which firmware achieves the best results? Title: Re: The KnC Saturn Miner experience Post by: r3animation on October 14, 2013, 07:27:36 AM I have a Saturn and I find 0.93 gives me the best performance of all the firmwares.

Unfortunately there's no cron installed on the machine so there's no way of doing it in an autonomous way. You need another host that will connect to the miner and the work (e.g. another linux machien where you set cron to do it every 30 mins). another way to do it is installing cronie on your miner: http://www.angstrom-distribution.org/repo/?pkgname=cronie download it and use this guide to install the package: https://sites.google.com/site/bifferboard/Home/howto/install-opkg-files Title: Re: The KnC Saturn Miner experience Post by: mo_mo on October 14, 2013, 02:34:50 PM I have a Saturn and I find 0.93 gives me the best performance of all the firmwares. what is your hash rate and which poll?Title: Re: The KnC Saturn Miner experience Post by: r3animation on October 14, 2013, 02:50:04 PM I have a Saturn and I find 0.93 gives me the best performance of all the firmwares. what is your hash rate and which poll?270gh/s stable @ 231w (bertmod reporting).

little update, installed bert mod, i could saw that i have only 4 VRMs to 0.9V and 50A av i noticed that i started to have really hot chips with the 0.94 (69°and 64° av) and today, a slight increase of 3 W at the killa watt i don't know if it's the heating of the house that started yesterday, cold days ... so i decided to move to 0.93 to see what happens: 71° and 66° av ... it is worst :-\ (on both an average of 450W at the wall ...) so i finally retried 0.95 + bert mod, but upgraded with FIREFOX and NO SAFARI: 293 W at the wall ... for 275 GH/s + 4VRMs a 0.7V and 43A av !! conclusion: go for 0.95 ! but, DO NOT UPGRADE WITH SAFARI ! -> use FIREFOX (as i said before, last upgrage to 0.95 + Safari broke my performances to 210GH/s) Title: Re: The KnC Saturn Miner experience Post by: coda on October 18, 2013, 04:04:54 PM perfomances update,
KnC saturn + AX 860 corsair: 291W (with a killa watt) max 278.6 GH/s (after a slow increase from 275 to 278.6 in a few days mining) average output voltage 0.75 V asic 1: 52°C asic 2: 48,5°C thanks to bert mod, not knc unfortunately (they sould have done this since long time) even with that, i think i'm fucked by the late delivery of knc products: http://mining.thegenesisblock.com/a/83b1a05b92 one week before, it was really better, difficulty is just getting mad !! Title: Re: The KnC Saturn Miner experience Post by: rograz on October 18, 2013, 04:52:42 PM I have a Saturn and I find 0.93 gives me the best performance of all the firmwares. I cant attest for the "all firmware" part but my saturn has been running rock solid at 260+ on elegius for more than a week using 0.93. Title: Re: The KnC Saturn Miner experience Post by: coda on October 20, 2013, 11:57:19 AM hi
just upgraded to Firmware 0.96: in the beggining, Hashrate goes to 280 GH and more !! but when a flushwork is done, hashrate goes lower, so it stablilized to same Hashrate than 0.95, 278.3 GH/s, but with cooler ASICs (-1 deg C av) and less HW errors -> higher WU: 3927, so my pool Hashrate is higher ! laters |
