Innosilicon's A4 Dominator, 1.2W/Mhs 14nm ASIC and miner, open for Partners

[GenTarkin]

Just shy of 4w/MH ....... so, hardly better than a Titan ... long live knc Titan!

Amazing disparity between the Title of this thread and the end result W/mhs ... haha!

yeah its about the same as a Titan, man I wish I had got my hands on some of those cheap titans last year.  Either way this unit is not worth more than 800 usd imo

Ow please   @innosilicon give me one to test, over and underclock and I will give you an honest review and measured userdata in return

Best regards emdje,

Yes, Innosilicon, please give him one to test! Emdje, I am eagerly awaiting your a4 custom image . I am running your image on my A2 and it is amazing.

[Chazaki]

Pictures please!!

Here are some pics:







I just restarted the miner to unplug the voltmeter but will update this post in about an hour when I get a more solid sample time for the picture.

Here is a picture of the miner UI after running all night:

Thanks for the input. Yes the efficiency is no better than the Titan.

[Chazaki]

To be honest it is entirely possible I have the mV setting wrong. I had to use a magnifying glass on the picture in the tiny (and i really mean tiny) manual that it comes with in order to read what mV to put the miner at (but hey, at least its something). Initially, it showed the voltage field as just a / with no number, but in the picture I believe it showed the value of 800, so that is what I set it to. Also, in my UI, when you set the voltage and hit confirm, it just resets back to a / (but I know it works, because the only way the miner will stay on is if you input a voltage before hitting start). It says "Voltage(mV)(500-860)" and then gives the ominous warning "Warning: Do not increase voltage at random, easy to burn down." Im hesitant to adjust the voltage much at all due to this warning.

noise level ?

[Chazaki]

noise level ?

When standing right next to both my A2 and my A4 about 4 feet away, I measured between 78-80 decibels. Made little difference with the A2 off. Definitely much louder than the a2

[hdmediaservices]

So if the efficiency is no better than a Titan -- then -- is this a SCAM?

Why would someone overpay to buy these units?  I'm lost here.

It seems that it is basically 2.5x as efficient as the 100Mh/s A2 units (which are selling for about $650 with PSU).

[jstefanop]

Yea these will drop down to about 800 each in 1-2 months...not sure how you get your power draw 4x worse than planned...

I figured such a small package with 1 fan was going to be louder, that's unfortunate

in a2 units don't go for more than 200

This means the A2's should drop in price may be 500 or less for one and titans should stay about the same ?. this is not a question  just a thought > the A2 's should still be usable for a while longer and Zeus miners  or lower will be dead now for sure .

[hdmediaservices]

Since these seem to be very similar to the Titans -- is it possible that no new chips were ever produced and this is just KNC chips (or copies of them) placed in new boards with new software?

Just curious how the stats could be so far off.

Titans MAY stay a bit higher...due to the fact of gen tarkin firmware is a miracle for keeping them running and not shutting off dies etc.....so that is solid. Also lightfoot can
fix them.

With 45 day warranty I can't say the same for the A4's (yet) .....IF the 2 guys above got an A4 to play with I'd not worry too much about the warranty. They are that good

on the above issues. Titans mainly also may go for higher in that you can split up the cubes (5) vs (2) so always may pay a bit more to get that extra cube etc

We will have to see...IF the A4's hang together well enough after warranty..then what will happen with out new players making scrypt miners to compete with the A4's

It very likely will shake out by say Jan or Feb due to difficulty to say an LTC network consisting of Titans and A4's ....and hell we could see another 2 years out of the Titans

and at least an equivalent 2 year run on the A4's ...in other words it could stay 'weird in scrypt crypto land" IF all LTC network is used for is for the Chinese folk to continue

to speculate because the like LTC (don't understand it but I will run my miner's as a merry go round for their enjoyment)

 The stats on the CHIPS aren't even close.

KNC liked "big chip" designs, Innosilicon prefers "more chips but smaller".

 Think Spondoolies vs. Bitmain for comparison.


 I would anticipate pricing on the A2 to drop once a significant quantity of A4s start shipping - but not real fast, they're still profitable after all even at near-average Electric pricing.

[hdmediaservices]

So the A4 definitely has a new chip design?  And not a whole bunch of A2 chips combined together with a really powerful fan?

If the pricing would drop on this by 50% - I would certainly be interested in some units.  But the noise and temperature are concerning.

Did anyone get to measure the actually noise created by the machine?

And did I read somewhere that after 4 hours the unit got up to 60 degrees C?  Is that right?  Was that temperature based on the air coming out of the machine?  Or the actual temperature on the chip?

If it is air coming out of the machine -- how in the world would one keep your room cool?  If memory serves -- I believe my A2 units would average 33 to 38 degrees C -- depending how many units I had in the room and if I had some AC going.


EDIT:  I believe someone mentioned noise at 88db or so?  That is loud!

Thank you for your compliment

Network Difficulty dropped a lot i guess that's the calm before the storm. so watch out, mine your ass off now with all most any miner . i don't know i don't watch the lite coin Difficulty like i used to with btc's.
