I hope that AM sticks to just selling the chips and not making miners again. Amazing how bad the Prisma experience was...
It was a strategic mistake to switch to chips only, that's why AM started producing be200 based devices (tubes/prismas).  You should expect miners and chips to be available with be300

+1. nobody knows better how to design a PCB than the guys who design the chips. Relying on 3rd party groups (technobit for example) to invest in prototype boards for multiple chip types simultaneously is less likely to get an ideal resulting design - ie the series-based design for voltage control, exactly what bitfury managed to do

You would think that but then you run into a company like AM that produced the prisma. Multiple people including myself have had one spontaneously burst into flame. Then AM has promised compensation they have not delivered. For myself they promised a new prisma for compensation on the burned up boards that I paid to ship back to Hong Kong from the US. Instead they shipped replacement boards leaving me to repair the damaged heatsink and pay for shipping from the distributor they shipped the new boards to. Then when they started acknowledging the other boards that have caught on fire or just don't work they promised to pay for return shipping to Hong Kong and to compensate for downtime. Now if you look in the thread where they posted that, there are no responses from AM. emails and PM's go unanswered and aside from a few boards they sent which didn't cover all the damaged ones there is no compensation either.

Any date estimates for miners with these chips?
Probably March for mass shipping

now i do have a question about these chip, they are not a straight drop in for the BE200's yes?

re-read, "FCLGA 5mm x 5mm" thats smaller then the 8mmx8mm QFN package

@Friedcat: what is the qfn next to the pin header that's labeled PMS01?

that would be a simple 8/16 bit micro-controller, iirc similar to what they used in the usb block erupter, gets the uart data off the chip then passes it over to ttl..

i could be wrong

Awesome! They're finally in!  Grin

Indeed something to look forward too ^^

Keep up the good work Friedcat and thanks for the update.

Will these chips be packaged in a miner for standard users or the development is already pointed on a datacenter product like SP did? (maybe it's too early to ask about it)

Very good news Friedcat  Cool

Keep up the good work.

Hmm... LGA vs QFN..  does that mean the heat goes out the top of the chip now?
 
From pictures you can see that heatsink is under a PCB. So propably it's old way to dissipate heat thru bottom...

Anger is a gift.
I'm surprised folks are so excited about this considering all the problems with under-performing BE200 products. I'm certainly glad I never purchased a Prisma and had to deal with all of those headaches! Also, Asicminer overpromised and underdelivered big time with the BE200.

Given their track record, I don't trust Asicminer enough to order a BE300S product right now. That could change in the future, but only after others confirm that the finished miners are actually a quality product.

i am exceedingly cautious these days. my rule of principle is that I never buy batch1 of anything.
and NEVER pre-order.
i'll wait to see what happens.

I bought a tube right when they came out and it has worked perfectly. Never got a prisma due to all the delays.

It should be interesting to see what happens in the next couple of months.

Fantastic news Friedcat!   It looks like a great chip, on time and on spec.  

Now, as a shareholder I have one request:  please hire the best sales team you can find to promote the BE300, and capitalize on this engineering success!  

ASICMiner has the best chip, it should have the best *everything*.  Including the best bottom line.  Wink

Congratulations and keep up the good work!

Negative ghost rider. Lga is similar to qfn in that they both eject heat out the bottom

This isn't the "same" LGA as like the Intel cpu sockets

Value will be measured in sats

Yeah sell chips and make this opensource THATS the only way hobbiest mining will survive. Groups of people can build their own miners =)
Make the chips cheap too of course.

And so it begins! It will be interesting to see the formfactor devices take as GH / chip [at these speeds] is much lower than BE200 which was ~7GH. Power per chip is also down so the hashing and power density of BE300 will be quite significantly lower. This is of course that AM doesn't throw out W/GH for $/GH.
We achieved 7.2GH/s per chip already, increasing W/G by about 10% compared to 4.8GH/s per chip.

There's a large room for $/GH optimization for mass production, and even if we do not do it, the $/G on 7.2GH/s setting is still decent.
