OK hash rate has been sorted out by the firmware mastermind.
Here's running it clocked up for 7 minutes

How far did you push it?

How far did you push it?

That was 350Mhz fan 90-100 and timeout 20 - no voltage change.
NMW was zero.

Edit: Note, no errors or rejects or anything
(R:1 at the top is BitMinter pool. It tells me I got a reject share whenever I connect to it as a backup ... without mining anything)

Hmm i dont understand - 350mhz on 20 chips should of been 7G/hash right?

that screenshot shows 5.855ghz, divide that by 20, and it gets you 292.75mhz ... am i missing something here? Is it 1 Mhz per 1m/hash?

You are right, something doesn't add up. Probably a bug in cgminer - bitburner communication somewhere. It's interesting cgminer shows ton of data, voltage for instance, and doesn't show bitburner clock rate.

i thought it was able to go uptp 9ghs?

The screenshot shows: 5.855G/6.660Gh/s
As far as I understand the second number (6,660) is the sustained hashrate (here over 7 minutes)
That is closer to 7 Gh/s
The first (5.855) is averaged just over a few seconds and may vary with time.

6,660 / 20 = 333, and notice that voltage on the screenshot is 1.223V, which is not the voltage burnin tested in the post here:
https://bitcointalk.org/index.php?topic=179769.msg2738301#msg2738301
he used 1.2 or 1.25 in that range. I don't understand it.

Well That was (as it says) 3am so I just wanted to post up an update for those wondering why it was hashing at half speed before.
Was a firmware glitch (as I said) that's been sorted.

... and yes those people misreading the cgminer display ... shame on you for using other software and not knowing what the cgminer display means

I grabbed that mainly coz it happened to have lots of 6's on it

8hrs is showing 6.696GH/s so maybe I need to play with the options to get the expected 7
(I'm not sure what I started it at ... it was 3am )

Small Update from me:

The Production board:


I added a second CAN connector so that Horizontal stacking gets easier.
And the red is just nice.

Single BitBurner:


Stack of Two:



FAN:


A quality industrial fan, these won't die after half a year of 24/7 use.

Project status:
Firmware and cgminer seem to be coming along nicely.
Voltage and Frequency setting are working fine.
I am currently waiting parts to arrive to be able to ship the orders, they should arrive tomorow.
Paperwork is also keeping me busy at the moment, lots of invoices to process.

[Dunkelheit667]

Lovely! Thank you for the updates burnin.

May I ask a low priority question? Do you have any specs for these green power connectors? Sitting here, waiting for... our chips and going to crimp some power cables meanwhile. Which cable diameter/circular area can we attach to the green connector?

[kano]

Ahhhhh - so that's what the two 90 degree brackets are for - lol silly me - Luckily the Duplo works just as well
Yeah I got a Gelid 100,000hr silent (mag-lev bearing) fan
Paid way too much for it - I got to my local Jaycar 1min before closing that day ...
But it's sitting under the desk in front of me, fan at 90-100% and I can only hear "a slight breeze" and nothing more.
( --avalon-fan 90-100 ) keeps it in the low 40's - ambient inside (winter) is 18C - but it's a little warmer there under the desk.

[eraziel]

Great news!

I only regret not ordering more chips now so that I can get more of these bad boys

[Stack]

It looks beautiful burnin. Congratulations!

Now to sit and hope that I eventually get one...

Less commenting, more OC'ing
Get that bad boy to 450MH/s already...

Anyone have 10 chips from batch one? PM me

[Rodyland]

Great news!

Only delivered chips as far as I'm aware is zefir's batch one.

Yeah and the chips I have ordered are part of zefir's batch one. So yes, I will get my boards in my hands hopefully by the end of next week.

Lucky!  (No, not luck on your part, you were quick, I was slow - I just missed the tail of batch 2, ended up in batch 3).

[eraziel]

I just want to say that I'm sorry for you and everyone else that has been practically scammed by Avalon.
