Topic: BFL board project COINTAMINATION - EU facility - ORDERS OPENED for Chili - page 40. (Read 73150 times)

this is very exciting. keep moving forward, i am certain you can outpace bfl if you manage things well.

I am mining now at Eligius, I will give CPPSRB a try, so this is what I see now

Don't use PPS... Use PPLNS. You will also get NMC in this case... Any you have much lower fee(3%) that NMC will cover it... Earning are not that stable but long term it is batter... But if you are a gambler you could look at Bitparking with no fee and merged mining for 6 coins(but 2 of them are more or worthless and 2 are not on normal exchanges)...

EDIT: And that explain why I got same results on 50BTC(I opened account to test) I didn't look at logs but now that I did see the same thing...

I know why I lost that GH/s, I was looking to charts in my pool and it seems that the stratum server had some issues and still having them, it was disconnecting and trying to reconnect when I logged to watch, I have to change that pool now.

 I tried BTCguild and it was working steady at 25.6 GH/s, but fees are 7.5% I will look somewhere else.

I will call him tomorrow since he lost about 600 to 1000 MH just by taking them away from me... He must be doing something wrong... And it looks to be incompatibility with BFGminer. I just did some test. I get less with it too... Pool detects 300MH less on my Jala... I put it on difficulty 1 so I get more stable results... But will run it for longer...

And BTW 8.4 is normal for A grade chips without overclock. And 8,6 isn't that special too. But 8,7 that we did saw on one jala is... It had really good chips...

Boost from 5.ish to 8.ish just from software..... nice.

Compatibility and settings for fine tuning can be a nightmare.

For a while I used GUIMiner with my GPU 7970
One miner on the card gave a steady 520Mh/s
Two miners on the same card settled at 275Mh/s each but the card did run hotter.
I even ran with 8 miners on the CPU (8 core athlon) total of 7Mh/s.

BFGMiner only managed 490Mh/s on the GPU.

The best way to compare miners is to check the results on the mining pool, also give them time to settle into the pool, at least 12 hours, then swap them over and do it again.
Also try on another pool for the same period, the pools do have differences.

CG and BFG are constantly looking to improve their software, so by the time you read this, and or test the systems, there will be a new patch on one of them, and the balance will change again.

My Pi running CGMiner shows 6.378Gh/s and an error count of 1.02%.  The pool shows 6.124Gh/s thats a loss of 4%  (theoretical calculated hash rate 6.365Gh/s)
My PC running BFGMiner shows 9.633Gh/s and an error count of 0.95%.  The pool shows 9.577Gh/s thats a loss of 1% (theoretical calculated hash rate 9.715Gh/s)

In the US even the ISP provider causes differences in the results.

The end result is, you need lots of testing, and make comparisons, and never settle in one place, or you may get left behind.

You should see the chips in that Jala... And it has only 13 and 14 engines working. But still it worked with 8,2ish on my computer...

Also I know from experience with my Jala that BFGminer dosen't work as good as CGminer. But you need 3.3.1 or more. Any lower it will not detect device correctly and start. I guess it is compatibility issue... Or WinUSB drivers speed up things...

I'm mining with asic erupters at the moment. Also with BFGMiner 3.1.4
On my win8 x64 the USB drivers refused to install, SiLabs claim it is because asic erupters all have the same serial number and try to all connect to the first COM port.
However with my Win7 x86 I managed to install and run 55 USB ports and all 55 erupters work perfectly, the drivers even self installed. (SiLabs need to find a better excuse.)

Not all PC's and OS's are the same, If you can try on another PC the drivers may install correctly.

I also run with a Rasberry Pi. This is also quite happy with multiple devices, up to 19, but seems to fall over every time I add more than this.

Your BFL 1 device is showing a lower hash rate 7.55Gh/s, and rather high errors (4.9%)

OK I also have no idea but I guess last one... And it looks like a problem since we had 8.8 to 8.6, 8.7 to 8.6 and 8.3 to 8.2... That is too big of a difference. So you might have problem with some setting... You really need to figure out why you can't install WinUSB drivers with zadig... If anyone can help him with this...

EDIT: can you test on another computer...

I am a new user of bfgminer, I was using cgminer, So i do not know exactly what to look for, I will read the Readme file and let you know which one I have to look to

So we lost 0,6GH? Or is BFGminer showing hashrate modify by HW errors? CGminer was showing 25,6 to 25,0 the short time we run them...

And yes it was just a software... We might increase the voltage next time too... Samples are OK with 1,2V. But I would not push real chips that hi without test since they have more engines running and higher power usage...

And thanks for kind words...

as I know it was only the firmware that Lucko is working on, he said that he will have a newer version that we wish to test again. so yes that is it, no hardware modification .

Wooow, not too shabby at all ... 24.71 GH/s.
This was probably more than a software 'jailbreak' I guess.

although I know who is Lucko in person, but I never knew that that guy is the same lucko in this forum till yesterday   , yesterday I PMed him to help me Upgraded my 3 Jalas, he kindly accepted and waited me for so long in his lab and did a Great job (for free ), the fact that it took him some time to do all that stuff, I am considering donating 2 days worth of mining to him, and I would like to ask people to help his project by donating what ever you can, awesome guy, smart and trustworthy.


I wish him best in this project  

edit: I forgot to say that we achieved 24.71 GH/s with only a HW-Avg. of 2.5%  , I had an Avg. of 16.5 GH/s with a HW.Avg. of 2%, so it is a win case of another overclocked Jala.

Well sorry to correct you but unless you got really low price(that I can't get in EU) on power module the price will be noticeable different... The rest of the parts are not that big of a difference I agree...

Just wanted to give update on Cointamination progress.

Sorry for any confusion on time frames, we placed our order with the PCB fab at a busy time for them so our design was in queue for a short time but things are moving forward and I have an estimated ship date from the fab of September 5th.

When the boards arrive I will post pics for all to see and I am sending 5 of them to the Assembly facility to have 5 production test boards made to be sure the design works as we expect it does. They have already been paid and also have sent our schematic package to them to have them ready ahead of time. Everything has been checked and double checked, additional components are being purchased directly by them - they are ready to rock and roll as soon as I send them the boards and the chips.

Build time from Assembler is 5 days and I will have the completed boards the next day.

I do have an estimated price of what it will cost the end consumer to buy the boards and have them mounted. Form has written instructions for the pick and place machine to build 2, 4, 8, 12 and 16 chip versions of this board, so all will be available however the price will not be much different if any.

Also we will offer DIY kits, as well as chip mounting services at our facility.

We will release an official price after I get a chance to talk to form and lucko about it. We usually meet once a day but thats about it because of time zone difference.

Web site still has to be completed in order to take orders, this will be completed by the time we have tested the boards. Payments for North American orders will be in Bitcoin only. Form and Lucko may accept other payment methods however that is up to them, and has yet to be determined.

I will post more info as soon as its available.

Status report on FrankenJala.

Jala board is strange. It works only to about 14 GH. After that chip performance drops and adding chips doesn't help. We are still tracking down the reason for that. But if there isn't a easy fix FrankenJala is only 3,5 chip board...

On the ather hand I did test firmware on 2 good Jalas and one not that good. Best one looks to be running around 8,7GH. We need to run them over night to see if this is the case. So firmware got 3 Jalas that we test from 16,something to 25,something... We got 15, 15, 15, 15, 14 and 13 engines working at stock voltage. It is still beta. So it looks good for COINTAMINATION board...

If we will release it publicly? We didn't talk about it yet.

Will you be releasing your custom firmware publicly?
Keep up the good work!

Getting assembly quote is more complicated then we thought. But we should have it by the end of a week... So can you please wait till then...

Ok, please send me order/delivery details.
Delivery 2 weeks after payed is ok.
I want to order 6 boards mounted with soldered parts but without mounted chips.
I need two additional boards without any parts for calibrating the solder machine.

Best send me details via pm (I hope it will work ;-)

Cheers...
