Very good news

My miner produce valid golden nonce now Cheesy

I dont understand why but problem was with my avalon chip.

Hi, "explorer232"
I made a PCB 16 chips A3255-Q48 total capacity 22-25GHs. But I see in BFGMiner 6GHs and produces errors .
Help me to understand. How can I check the work of each chip on the board?
See my log file

Wow nice work and subscribed in youtube, sorry for the commentary in youtube xD
From now i will buy a arduino due i've been practising a bit witha duemilanove and even though im a noob i will give a try

Working device with 1 avalon clocked to 280 MHz.

At the moment I am testing Avalon clocked to 300MHz

Nice work! Too bad an Arduino Due is required. I could sponsor you with an Uno or a Mega if it was of any use to you, but I have yet to find a reliable supplier for Due boards. Anything else you need? I have a lot of Arduino boards and peripherals listed here: https://bitcointalksearch.org/topic/now-on-bitmit-arduino-106155

I thanks, I'll send you PM

Tbh I think we're too late with avalons...If I get some fury chips fancy doing it with them ? Cheesy

Hi, No problem I am planing to implement bit fury chips to this device

I have already fixed some bugs so all shares are accepted now. Avalon is clocked to 128 MHz in my testing device because I do not want to melt it

but, a single chip should produce 330mhs not 110

Also percentage of rejected shares looks terribly. But i think it's no problem.
I think it depends on time of measurement. Look, there is cca 7,5 minutes uptime.
I use slush's pool and it's the same with my fpga's & asics... simply: measurement, based on accepted shares is crappy and results are real after long time .. let's say 5-10 blocks of hashing .)

I think, explorer got enough skills to get bitfury's chip hashing

looking good...

but, a single chip should produce 330mhs not 110, so there maybe some room to change clocking or voltages there...
The single usb eruptors get 330mhs, and their not overclocked....

Congratulations by the way, that's a great achievement. I'm constantly in awe of the technical skills that are being demonstrated by people on this forum. You're all heros Grin

.

Seriously though, bitfury chips look like they have some real staying power in terms of power consumption and $/GH/s. There would be interest if your project heads in this direction at some point.

Congatulations! I also managed to get mine to report valid nonces last night. I just had to flip the location of the words in my midstate and data arrays. Good luck!

+1, congrats from me too

a very compelling proof of work and your skills.

too bad the timeframe for running avalon chips with positive ROI will be short. are you able to support other chips also, e.g. avalon 2gen, bitfury, and other upcoming ones, or is this very much tied to avalon right now? i'd love to see your work results as an independet / DIY kit at sparkfun and so on, at least

I'd appreciate it if you let us know what you did to get a valid golden nonce when you fix it because I've been having a similar problem and I have been trying to get it to work for about two weeks now to no avail.

have new chips arrived ?

Hi, thank you very much. It is allready arrived. I have another result with new chip. I'm working hard to finish it.

Web Interface test. Calculating hash speed isnt very precise at the moment
