[Work in progess] Burnins Avalon Chip to mining board service

[tiros]

This is very gooooood morning seeing these chips waiting to be tested.
Happy testing, burnin!

I have rerouted my ragingazn chips to you (as I have my Sebastians and zefirs).
Would love to pick'em up in HH myself, but will eagerly pay for INTEX NEXT-DAY out of my own pocket if that doesnt work out.

hi burnin,

i could not find the answer in this topic.
Are your prices (80EUR/100EUR} with or without  Mwst/VAT for EU customers?

very nice case design ideas here... https://bitcointalk.org/index.php?topic=223680.0;all

# 10/20 Avalon chip module - 2.82/5.56 Ghash/s nominal speed

It's been low-level bugging me for a while why the 20 chip board is not spec'd to be exactly twice the speed of the 10 chip board.  It just struck me today - is it a typo?

2.28/5.56 Gh/s would make perfect sense...

Typo. Should be 2.82 and 5.64.

Hello. A board with 20 chips hash with 5,6 gh. Is with the board overclocking possible? And how much percent are possible?

I guess you wont read anything from burnin today... *g* Looks like he has some things to play with... (Sorry for spoilering burnin... (though one could guess anyway that they reach today))

Correct,  I will do some initial tests dead-bug style.

There they are:

holy， cant wait burnin。

any updates burnin? making sweet love to those avalon chips yet?

[tiros]

I bet burnin have this image in his head right now

Hurry up Avalon!

My God, I don't understand a word from this thread.

20%, from what I have heard.

up to 340mhz / mhash

no, thats wrong. max 300mhz stable / 6.5%

Includes VAT, but I still wait for the quote for the final PCB revision for the final Price.

Theoretically one could set it even higher, needs experiments though.

Yes, but they are proving to be rather bitchy, at least without a proper PCB.
Constructing the test harness for it took hours of very careful soldering under a microscope.
Maybe my clock source has to much jitter, or the PLL core voltage is too noisy for it to lock.
I will continue testing though.

Anyways I also pushed in other directions: case designs
Even though "case" is a bit of a exaggeration.
I plan to provide two options at opening of the website:
1. Basic foot for the tower of modules, to provide extra stability.
2. a Foot with a place to mount the ATX power supply and the Raspi.
A 19" Case is in planning phase.

Could any of the old GPU miners recommend me a good brand power supply that I could offer along with these boards?

Hmm, fingers crossed. Good luck!

Well, there's Corsair, Enermax, Antec, OCZ (and many more). But depending on the amount of boards you want to run, efficiency would be a key factor (next to stable voltage obviously). So you might end up with a relatively low powered psu for most buyers (in the range of a 20 - 200 chips). Efficiency is often tied to the load % on the psu, so selecting a proper one might not be trivial (although a Corsair HX650/HX750 will surely do the job. Maybe Antec Earthwatts Platinum EA-550)

I can recommend the reviews in here Hardware Secrets. Very detailed for your personal configuration needs.
