no offence, but following your posts about your steady fumbling around with your machine, I just waited for a post like this.

My stuff is running 24/7 without touching, with the original 0.95 firmware. I just checked that everything sits well after unpacking.
If its not broken, don't fix it and never change a running system. Phoenix will be probably the next to cry.

Where do i get enablecores.bin?

Is a Hero Member mudwrestling match coming to On Demand soon?  lol

What is this crazy Contra type pattern you are trying for a hard reset?  Its very easy, just hold the button down for 5 seconds and you will see a bright flash of light then power down and power up.   This reset has helped in the past with a few issues. (prior to .95)

wish I could get my saturn to perform like yours...i tried your steps but seemto make it much worse for me...so back to .96  where I have 20% hardware errors and just shy of 3800 WU, hashing around 250GH/s on cgminer, but server says 210-225 GH/s....stabilizes to 250GH/s after 24hrs last time, so hope this time too....but am hoping it can go like phoenix1969's 3 Saturns at 275GH/s each at the server side....now that is over delivered.

be sure it's not a temp. issue....they have been known to leave the plastic cover between the heat sink and the chip...if that don't help, try connecting the asic board to a different port on the beagle...shits and giggles at this points...can't hurt.

Okay, like people said in kncminer forum. You go to fw .95, you delete /config/asic_test (NOT THE Bin file, only the config file). Then, you upgrade to fw .96 and you get a new asic_test file with bad and good cores quickly mapped. Now i need to figure out how to enable more cores without running enable_cores.bin, because i don't want to enable all the cores, i want to just enable most good ones that fw .96 misses

LOL
You who had zero to do with them before they released the hardware ... ah your funny.
Go back to what you are good at - coming last in elections

I am trying asic_test, maybe that will fix it by mapping the good and bad cores. What happens is a lot of cores get enabled, then some of the shares are like 1k-3k , then it goes to an average of 2 Mb/s. I really hope this asic_test fixes it. I am shit out of luck now

Hold on, have you tried booting each board individually and seeing what each hashes at on it's own - without any other connected?

You might determine where a fault exists that way.

In any case do that and call cust serv tomo.

Also take note of the length of time the bright LED stays lit for. 3-4 secs, or a blip. Whether you end up with a solid red, or green light once boot has completed. Do this for each board individually.

Nope, it sucks. It is broken. DAMN. =(

it goes through enable all these cores. then it disables all those cores like 5 seconds later. and then it stays less than 5 Mh/s

I was going to sell this miner, and now I lost 7k.

not really, the saturn has now more WU/s (4370)  and less HW errors (about 7%) with 0.94
and before  with 0.95 and 0.96 it had 15-20% HW Errors  and 3600-3700 WU/s

Okay, part of the beagle board was not pushed all the way down. maybe that was the problem. I don't know if that happened before the problem or after. I'll see and update you. All my bad luck, i hope this isn't another one. it psychologically hurts soo much how much bad luck I have had in recent years.

Paperclip?
Some people won't know about that.

Good post. Forum members doing KNC's job again.

For one chip, after a while and after one run of all enable from disable and then some disabled, everything runs fine and stable. Then, after another run mostof the cores for some die get enabled from disabled state. Then, it continues to work fine. Then, like almost all those cores get disabled again, and then, my average hashrate is 2 Mh/s, BUT my 5s hashrate is 526 gh/s. The average hashrate is increasing only by .003 M/h/s, So maybe there is something wrong with cgminer? It didn't have these problems until today, and it ran fine for two days straight.

I have so much bad luck in my life. what the hell.

A few good check points when you receivr your miner. Commom sense.


1. Check for external damage. The plugs sticking out could be damaged and/or even the NIC port. Just a good visual to be safe.
2. Open up the case using your handy torx bit. Make sure you mark which direction the top case is on, so you can put it back on the same direction. Just makes it easier.
3. Before touching anything examine everything inside visually or even take some pictures. Notice where plugs are plugged into, fans are plugged into, etc....
4. Check the heatsink fan shrouds that they are on tight and secure to the heatsink itself. Make sure the fans themselves that are IN the shrouds are secure and tight as well.
5. If the heatsink fan shrouds are on and secure make sure they are fairly snug/tight. There are two phillips head screws holding them on and one of them was very loose on my Saturn.
6. Check for the plastic chip protector that would be between the heatsink and the mining chip. You can visually view that with your eye and a flashlight. There has been a great post about that on here with an awesome up close picture of that. If you do see the plastic you will need to remove the heatsink and remove the plastic. Then before mounting the heatsink on again CLEAN all the old thermal grease away the best you can. Before mounting the heatsink back on you need to re-apply some more thermal grease. I use Artic Silver 5 high density synthetic compound. You can find it on Newegg or Amazon easily. I bought a large 12 grams of it, since I use with my work all the time. Before installing the heatsink make sure all the torx nuts are tight. When the heatsink is installed you can only access one of the two easily.
7. Make sure your beagleboard is secure and pressed all the way down into its pins.
8. Make sure the controller board itself is secure with the torx screws.
9, Connections! This is obvious. Make sure all wire connections are secure and in place. I usually unplug them all and plug them all back in securely. It's just an OCD thing with me. This includes the blue power cables, and the data ribbon cables, along with the fan connections.
10. Make sure the rear fan screws are snug and tight. Those two big ones that bring in the cool air.
11. Make sure your power supply is OFF. Plug in your PCI-E connections and your old school 4 pin connector from your power supply. That is to power the rear fans. Make sure all connections are snug and tight.
12. Power on your power supply and view the lights on the beagleboard and controller board itself so you can familairize yourself how the process is on power on.
13. Wait approximately 3 minutes then log into your router and check your DHCP log. You should see your miner in there. Or run the command arp -a and then you'll need to figure out which IP address is your miner. Since I have over 25 devices on my network it is a little more difficult to find. That's why I just used my routers DHCP list.
14. I DID NOT statically configure my miner with an IP address. I reserved one in my router for it, so whenever my miner boots up it will ALWAYS have the same IP address no matter what. It does this by me telling the router the MAC address of my miner. I normally set the IP address of what it defaulted to.
15. Once you know your IP address, plug that in your web browser and login with "admin" and "admin". There are some settings in there which I won't go over. They are mostly self explanatory.
16. Upgrade to the latest firmware. The latest firmware is there for a reason. Most companies won't tell you the exact reason for a new firmware, but I was successful in upgrading my firmware to the latest. Before I upgraded the firmware, I made sure to stop mining completely. "screen -r" into your miner and press "q" to quit. That will stop mining for that session.
17. Reboot, login, check things out. Start hashing away keeping an eye out on the temps. Since we don't know what the max temps are I wouldn't let them go over 55c. That may be on the low side, but since we can't confirm the normal operating temps the lower the better.


I bought two Saturn's. One for myself and one for my dad. I bought myself an RM850 Corsair power supply. I was running both Saturns with no problems off this one power supply. And according to my electric meter I was only pulling 600 watts and the power supply fan only came on randomly. This is a very efficient power supply and I highly recommend it.

I do have more to say and add in here, but I just want to start a basic check list. The KNC manual has much to be desired so maybe they'll add their own check list in there in V2. Who knows, I just wish they would participate with us here at this time. This is actually the PERFECT time KNC could participate with it's customers while receiving their hardware. This is when most questions are asked and it would probably cut their email in half. I hope this helps and if I left anything out (most likely I did) let me know. I can always go back and edit.

Thanks!



Pleasd feel free to add/change.

temp is too high in my opinion. did you check if "peel off sticker between heatsink and chip has been removed"? see link below.

https://bitcointalksearch.org/topic/m.3368753

EDIT: also with closed case the air flow is much better because of the two wings inside the case. I got lower temp of the second ASIC slots behind the first ASIC slots. but it need some time the miner adjust itself.

FYI: auctioning a Jupiter to be shipped tomorrow (https://bitcointalksearch.org/topic/knc-jupiter-525ghs-stable-in-hand-immediate-delivery-fast-auction-314656)

with fw .95 and .96, they each give me a high hash rate whereas .96 is 20 gh/s more; however, after running at that level for four hours the hashrate went down to 1.86 mb/s. Then, after restarting it again, it would give out after about 30 minutes; then, it would do it in like 15 minutes. Is my Jupiter dying?I ran enable cores.bin. I don't know what could be wrong. Bertmod reports that most of the cores are on, only about 38 out of the 768 are off. Furthermore, the 5s hashrate shows it is getting a 525+ gh/s , but the avg hashrate is 1.86 mb/s. My hardware error rate is at about 7%

The 3rd asic slot chip reaches temperatures of around 67.5. Maybe there is a hardware shutdown temperature it it goes a little higher than that? I put a case fan on it and it runs cooler. I'll see if that was the problem
