[Guide] Dogie's Comprehensive Manufacturer Trustworthiness Guide [1st Feb 2016]

[dogie]

Blackarrow have had an 'O' infraction for quite some time now.

Ahh, sorry I misunderstood (it seems obvious now). I assumed that such as egregious general attitude to, and direct breaches, of ethics would take the absolute score for this section down to -5, but I understand now that it is simply a modifier. What would it take to lower this to zero? Are the negative applied once regardless of quantity of breaches, or across x-size time frames etc?

Mixture. The category isn't designed to be super detailed because then one gets accused of being biased for every 1 point each way.

I may be am biased, as a buyer of a batch of Prismas who has yet to receive them, but ASICMiner has also failed to reply to -any- emails since the original purchase (either friedcat or phasebird), so although I know some have shipped I have seen no communication since the 25th from them. I'd recommend lowering their communication score again:

https://bitcointalk.org/index.php?topic=791827.msg9425492#msg9425492

Also, the Prisma may not have been a pre-order because the hardware was already designed, but the BE200s were not in-hand, and when the first batch came back flawed they were unable to react (let alone communicate) fast enough, so I'd ding them again for handling a hardware launch extremely poorly.

I agree communication has been absolutely terrible. TBH I think it is significantly impacting the company's sales.

The BE200's were in hand, just many of the chips were defective.

Do you have a source on the chips being in hand but defective?

The Bitmain calculation appears to be off by 4 points, unless I'm doing it wrong.

10+10+4+10+6+10+10+8+10 = 78

As known by OEM producers, several large batches of BE200 had problems with
popping chips affecting whole boards due to the misoperation from the packaging
company. It hindered afterwards chip sales and delayed the starting time of
Tube/Prisma sales. Later supply of BE200 has no such problem and filtering process
on old BE200 is also underway.

Sounds like this happened a while ago.

The best source I have was the post on October 24th from friedcat in a different topic I cross-posted it to the Prisma topic here:
https://bitcointalk.org/index.php?topic=791827.msg9436661#msg9436661

They gave similar details on their Facebook page around the same time. No other details have been released from friedcat that I've seen, and phasebird's only reply was in the Prisma topic on the 25th:

https://bitcointalk.org/index.php?topic=791827.msg9324615#msg9324615

It sounds like either TSMC had damaged some of the ASICs, or (more likely) there's a defect in the way they sent the VHDL to TSMC and their tapeout went...poorly.

It's enough that they aren't doing another run of BE200s, and friedcat jumps into describing the BE300 and its power efficiency and timeframe as being Q1 2015. So I think the BE200 issue is on ASICMiner's end, not on TSMC's.

There are no denominators. It's simple addition. Why are so many people who are fascinated with bitcoin so bad at math?

I resemble that remark ....no refund no roi knc Titan 1st batch miner.....by the by doggie ....knc admits that its first batch chips/dies are bad but won't refund
....and have now stated RMA's will take at least 2 months ...their timeline (will likely be longer) I'm sure you are aware of that fact right (can give you links) ....

http://forum.kncminer.com/forum/main-category/hardware/66533-missing-dc-dc-converter

kurt admits such last post on this page..1st batch dies are not up to snuff...but ....still no refund

also

they admit the firmware is not up to snuff either (often quoted on site) and promised scrypt n conversion on miners put on hold (imho forever) that
they used to boost flagging sales before taking the titan off the sales page

anyway yeah bad bad I am at math don' t ya know

(ah well.....did ok with the jupiter....not so good with the titan....only if BTC goes below around $200 usd will I be a crying and if that becomes the case
will simply be part of the flood of tears here on bitcointalk don't ya know)

but yeah.....knc imho is due for another drop in the rating ....

note to self: avoid all 'pre-order' math....

That's just yield, the same occurs on any non binned chip miner. You provide more hash rate than required so that even with failed chips you still make the spec.

Hello,

Does anyone have any info about https://www.mining-asics-technologies.com/ and their Bitcoin and Scrypt Miners?

I'd like to kow how legit they are. Thanks

All ASICS are out of stock, scrypt apparently available, not sure I have seen these guys mentioned on the forum before?

Its a scam.

They took preorders for sha-256 ASICs which they claimed to have designed/built but it later turned out they just bought the hardware from another company and claimed it was their design.

Then they claimed to be designing a scrypt ASIC. Many preorders and delays later it turns out that yet again they just bought the machine from another company.

Alcheminer is the company making their scrypt hardware. I tried to get them to clarify the relationship between themselves and MAT and was pretty much ignored. For that reason I don't really trust Alcheminer but they are definitely much less shady than MAT.

Anyways, I'd personally just wait for Bitmains new scrypt ASIC to make a decision.

I am looking to buy some scrypt asic,but in this period probably smarter choice is wait and see what will happened.
At these moment best buy for me is inno sillicon a2 terminator.110mhs-1500$-1000w/h or 35mhs-550$-350w/h.

I found this about Alcheminer:

Thanks for your responses guys.

Any prisma review? Or setup?

In stock, working on it now.

[DebitMe]

Dogie, please look at BlackArrow's thread started by  Theymos.  There is now evidence that they have been mining on customer equipment with GPK's recent post.  Please add to original thread once reviewed.
