ASICMiner BE300S Samples Arrived, <0.2W/G Achieved at Board Level

[MrTeal]

I would be very interested in purchasing a sample as well, if you do end up selling some. Chip docs would be appreciated in the mean time though.

Just did a quick calc and a rig in the style like the bfsb 48card bitfury rigs could pack 3.5TH into ~1Kw

Excited

I think something small like Rock Miner did was pretty cool (the 100GH unit). Maybe make a pod like Bitmain...something that does not require a computer PSU to run.

To not require an external PSU means they have to put in an internal PSU.
Which means additional certifications are needed, and can sometimes delay customs/shipment...

(that being said, I agree it's nice to have)

I think what he's saying is, not necessarily an internal PSU but also not a separate external high-current PSU. Probably still an external supply, but something more like a brick. A 200GH VRM-less system would pull about 70% load on a 12V 5A brick and could probably run pretty quiet if built right.

We'll likely see retail products sold closer to .4.

[Dr Charles]

This is great. I will be following this closely. Congrats on the preliminary results and I would also be interested in getting my hands on a couple samples.

Good Luck!

Any word on low volume sales?  It'd be nice to see a decent chip available in less than 10,000-piece quantities...

[SFMiner]

Very exciting, I'll be following this closely as well.

MrTeal, Any chance you would call the resulting product the "Cayenne", or would it be more of a "Serrano"?  Either way, sign me up - I am on board if you end up using these chips to create the successor to the Chili and Habanero.

E.g. Like bsfb when they were selling Gen2 bitfury chips?

Yep, good data (especially on the function of the PMIC) would be pretty nice, at least to get a rough idea of feasibility.

Oh yeah, it's mentioned that the hashrate is proportional to the core voltage. I'm guessing that's got an internal voltage-controlled PLL scaler? It'd be good to know the formula for that, or put some Vcore data on your first-post W/GH chart that could be extrapolated. It'd be a good reference to get people thinking.

On board efficiency (average of 4 boards):
    2.8GH/s | 0.1961W/G
    3.2GH/s | 0.2026W/G
    3.6GH/s | 0.2095W/G
    4.0GH/s | 0.2145W/G
    4.8GH/s | 0.2204W/G
    5.2GH/s | 0.2257W/G
    5.6GH/s | 0.2314W/G
    6.4GH/s | 0.2363W/G
    6.8GH/s | 0.2439W/G
    7.2GH/s | 0.2495W/G

I would really like to see the core voltage at each level. 
I'd like datasheets on both chips too, but even knowing core voltage vs. GH would be super useful.

5.2GH/s | 0.2469W/G@0.55v sound not so good, and the cost is high...
bitmain's 3rd Gen chip have achieved this goal @0.6v and  the miners in mass production, i think FC is late at this round...

Sorry, this just smack's of FUD. Can you post a link to the Bitmain gen3 chip, it doing <0.25J/GH @ 0.6V, or someplace where FC stated what the price of these chips is going to be?

just some information from friends， I believe its truth. bitmain will sell S5 miner with gen3 chip in the next few days，wait to see...

The PMS01 IC provides all the functionalities needed except the mosfet for chaining the chip into a string.

For the one-chip board, we still choose to use it instead of a bunch of buffers and LDOs for board simplicity.

I think something small like Rock Miner did was pretty cool (the 100GH unit). Maybe make a pod like Bitmain...something that does not require a computer PSU to run.

The problem is that there may not be widely available high efficiency power bricks.

Competing with 70% efficiency bricks agains professional miners with 92% efficiency PSUs is hard.

[hurricandave]

If you want to see the numbers of home miners continue to grow then you must admit it will be from newcomers to BTC. An introductory sub-$100 miner is still going to be the best proponent of that. SO, would you like to watch Bitmain and others develop loyal customer base from providing an introductory device? Or do you gamble on breaking that relationship/loyalty between them and get the business from their pockets when they mature into highrollers.

look into, i think Delta's, laptop/desktop external PSUs, they hit the 87-90% but they are a higher voltage DC.
There is also nothing wrong with using a PCIe power adaptor off a desktop internal PSU

There is if the aim is a starter device. To us the idea of paperclip jumping an ATX PSU is second nature, to newbies it's daunting.

I've been around personal computers since they were invented (Imsai and Altair). The idea of jumpering the PSU with a paperclip was daunting to me. The first time I did it I half expected the PSU to blow up. LOL.
