back to all 3 sats running 0.96, but they all hang around 275 now still  
same procedure on all 3 saturns...
1. flash 0.90 on the miner, reboot
2. flash enablecores.bin to the miner, POWER CYCLE the miner.
3. putty in and watch cgminer until it crashes, when it does, go to the gui page again, and flash 0.96 back onto the miner, apply, then POWER CYCLE the miner(turn off for 15 seconds via the power supply switch)
thats it.
i had 3 sats going at 255, 265, and 275....  now all at 270 - 275ish

THAAANNNK YOU VERY MUCH Phoenix. That was it. My slow 220gh/s saturn runs now at avg 275GH/s and my Jupiter at avg 555 GH/s. Both with the same firmware at the end and both with the same flashing steps.
But i have 1 difference
Jupiter with about 540 Watts and each VRM 35.6A - 40.1A. Boards with 8 VRMs
Saturn with about 430 Watts and each VRM 53.9A - 58.1A. Boards with 4 VRMs
The amps are really freaky....

you're 'overclockin' with pre-95 FW   (voltages run high, amps out over spec, but make ASIC jump hoops more for higher WU but higher HW error%...as you see, the 8 VRMs can handle it..)

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

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.

[WastedLTC]

can someone explain exactly what the "hard reset" does...   does the firmware stay, or revert to...?

That "hard reset" never worked for me. Press the button 5 times, wait 5 seconds, then presss again 5 times. Nothing. Nada. I even have a constant ping on the IP address and that never even goes out. What's up with that hard reset? I truly would think a total power off is the trick.

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)

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

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.

Hi guys,

so I played a little with firmware settings, voltage (0.7 / 0.9) and after a few restarts I now have my Mercury running stable at 130 GH/s and only have ~15 cores disabled instead of 40 cores with firmware 0.90 and enablecore.bin.

I made a few photos from the ASIC board and found out that the VRM with an output voltage from 0.9V they reach temperatures over 89°C.

Here is an album I made:

Sorry but maybe I missed some news along the way. Are you able to change voltage at will? Or are you saying that using 0.90 fw means using higher voltage, while 0.95/96 lower voltage?

edit1: very nice pics by the way

[joeventura]

A well, just for once i wil do the picture also.

Just for you "joeventura"



And don't bother to reply, you are on ignore.

No worries, sent you a nice response in PM.

Such true words, I checked fans and flashed my saturn to 0.93 the day I got it and not even logged into the web interface since.

Jesus man, I've been reading 12 pages just about talking about power supplies! WTF?

Just buy this one: http://www.corsair.com/us/power-supply-units/rm-series-power-supply-units/rm-series-rm850-80-plus-gold-certified-power-supply.html

You can use it for a Saturn, 2 Saturn's or one Jupiter. When I use it with my 2 Saturn's it pulls down exactly 600 watts, which leaves a little room to spare. People buying these 1000 Watt monsters. Crazy.

Yes, and the efficiency looks quite good.  

I see that using 0.90, which I believe uses the most energy and produces a high percentage of duplicate shares that count as rejects, this on a Mercury, using a cheap 12vdc switching supply (the output voltage of which I can adjust) and an inexpensive BBB supply, I'm drawing 259½ watts (174 watts on BertMod) at the wall so it's an efficiency of 67% so that's not great.  Of course the BBB draws and it's 1 BBB to 1 module while with a Saturn it's 1BBB to 2 modules.  

I may be able to increase my efficiency even more by dropping the ASIC PCIE voltage down.  The onboard vrms aren't completely efficient and lowering that voltage might find a sweeter spot.  That's the only advantage of this cheap supply designed for powering a huge load of LEDs, the output is adjustable.  That and its cost, $27.88 free shipping and a few bucks for tantalum capacitors I added.

Still, 600 watts on 2 Saturns, that's 150watts per.  

I'm getting 134GH/s as the final settling point on 0.90 at 174watts on BertMod.  If you're getting 150watts at the wall per then I suspect you aren't getting 134GH/s per avg.  Of course you could be if the efficiency of the later firmware versions is great but I've heard that's at a cost of hashrate.  Eliminating the duplicate shares would have gone a long way to increasing efficiency.  I'll know later today when I go to higher versions of the firmware until the duplicate shares stop.

One of my miners hashes to a max for a like 4+ hours straight; then, everything fails. it goes to like infinitety hardware errors and 0 hashrate. What could be wrong and how could I fix this?

you're probably using pre-94 FW and one of your dies/VRMs is a bit flaky

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

I suggest, if you're running with the top off, cut a piece of cardboard the width of a front fan, about 5.75" wide, and high enough to abut the front of a front or both front ASIC module(s) and reach under the lip of the top front of the miner, and put it aside.  When the hashrate crashes down, try putting the cardboard between the two front fans so the outside halves are pushing air into the box but the center halves are pushing air down onto the BBB.  I think it's the BBB heating that causes the drop after hours of otherwise good hashing.  If I'm right, when you put the cardboard in place, you can watch the first figure in the cgminer hashrate, that you can view ssh'ing in using putty, immediately rise up.  If I'm wrong it won't.

Well I am at a total loss why my Jupiter does not get above 410Gh/s. (380 at BTC Guild)

Tried every firmware, tried the Enable cores patch and still the same.

Look at the results from bertmod, I have 1 Asic #4 showing (192 Cores all on hashing at 130Gh/s)

The other 3 Asics (# 0 , 2 , 3)

#0=80.58Gh's , #2=93.36Gh/s , #3=88Gh/s

The DC/DC are all showing 4 on and ok apart from Aisc #3 only showing 3 DC/DC on and ok , no other found.

Temps are as Follows

HW status:

ASIC slot #1: 53.5 ℃
ASIC slot #2: -
ASIC slot #3: 54.0 ℃
ASIC slot #4: 61.0 ℃
ASIC slot #5: 58.5 ℃
ASIC slot #6: -

Thought this was to be plug and play, I have spend Hours upon Hours trying to nurse this Lemon back into life.

Got in Mining on the Day it arrived Wednesday the 16th at 14:00 (UK time), Mining via BTC-Guild I have the grand total of :-

2.25 BTC's

Any Suggestions on what KNC should be offering to do when I call them again tomorrow.

Temps are rather high. Tried additional cooling? Cool down the bbb as well as the vrms etc.

It's up to firmware what Output Voltage are used. Now I use 0.94 with 0.9V (194W power output). If your boards are running fine with 0.7V I recommend you to use it. With 0.7V I only have half the output power (about ~100W) but more cores disabled (40 cores of 192 disabled).

Hello,
For any of you want to try solo mining with KnCMiner follow these steps:
- In a windows or linux pc, modify local (appdata) bitcoin.conf, add line rpcallowip=localip e.a. 192.168.1.xxx
- Ensure that your firewall does not block bitcoin-qt
- restart bitcoin-qt
- In KncMiner mining tab set as pool 192.168.1.xxx:8332, user and password whatever you have in bitcoin.conf
- Restart CGMiner in KnCMiner Mining tab (web GUI)
Works just fine.
Depending on your luck you may find a block earlier that expected block finding time e.a. 51 days for a saturn or 24 days for a Jupiter.
Also you can save from the increasing difficulty.
Of course the risk remains.

When I fuss with my cardboard and fans, I sometimes get a reboot.  Since I run, at the present, without the top, center cardboard cooling the BBB, a 12v fan sitting inside blowing on the left side of the module, another 12v fan outside the case blowing on the right side of the 1 module (Mercury), I added another piece of cardboard to the right of the BBB, to the side and up to the module, taking the air pushed out the side and directing it to the module.  The miner white light came on and off as I moved the fans, perhaps a loose pin in an added fan connector, but it started again right away.  Put Bertmod back but earlier tried the 0.2.1 and found it works well with firmware 0.90, looked at my cores, which I could with the 0.2.1, and earlier their was a single core not up, but now there are four 100% cores and the BertMod says the power change from adding that one core on firmware 0.90 with ~0.9v to the 4 vmr's, was 174 watts with one core down and 180 watts with all cores running.

+1 Im starting to see a pattern of conceit among hero members.  I would rather use BFG modded fw over CG every day this year (with that said I felt like luke-jr was a little conceited too)  Thanks you two for the great sw and all - specifically the free factor, but acting egotistical doesn't help your cause at all.  

You're free to do what you like. By the way, though, cgminer is my project. Kano is a value contributor but not the maintainer, and while I have complete control over what code to include, I have zero ability to control what he says or does on the forum. Note that in the future, I will be working on the kfc driver code.

cool, my offer of letting you play with a saturn is hereby offered to cklovas...... ! you da man, ty for being so understanding!



on another note (totally off -topic)  It's a goood morning...

Nah, that can't be right as (4dies)(48cores)(6watts)=1152 watts.

So, at 100%, 180watts/(4dies)(48cores)=.9275watt/core.

tried 5-5-5 reset - nada

changed ether cable - nada

found the IP easily with arp -a, solid green led, fans are purring, blue leds twinkling
