BTW, I realize the pix is upside down, but I can't edit it...

I've seen worse necros but not often - you DO realise you were replying to a post that was almost a YEAR OLD?

I would not be so amazed, these were a fantastic investment for some people.

Someone is crazy to pay $1000 markup for that miner on ebay -- I'm amazed they already sold one

But I know that seller is legit -- they have it listed on their site as well - http://www.deepinthemines.com/

I am not affiliated with the auction or the site.

I do not know if this listing is legit and I am no way connected

but I thought I would share this A4 listed on ebay 136Mhs@520W
(you get 2 units per buy it now) says its in hand

http://www.ebay.com/itm/A4-Dominator-280Mh-s-Litecoin-miner-like-zeus-thunder-x3-gridseed-a2-terminator-/112167146124?hash=item1a1daed28c:g:qDAAAOSwNRdYAUzz

I know I haven't gotten the notification from Inno yet that they want to ship the group buy order that our little group placed.  They will be invoicing us for the shipment where we have to send another wire transfer to them for the shipping.  I haven't heard of anyone getting theirs yet.

So has the first batch been sent?  Has anyone received theirs?  How is it?

Far too expensive, 5 units is 1400mhs or $36 a day at current prices

with 1800 x 5 I could build 5 ethhash rigs 

I sended mail with pre-order two day back. No answer.

I thought the new specs on the A4 were now 1100 watts at 280 mh.....I thought it was stated as such in the threads ...also a price of 2100 bucks now ? I'm also not sure
if the group buy is still going on? Feel free to correct me ..but the figures I was working with



Point taken...but with gen tarkin 3rd party firmware and other mods (maxumark bracket..copper heatsinks replacement on all dc/dc's and gellin extreme thermal repasting) they will very likely go 2 more years now..the stuff has NEVER been as stable or run as good

my stuff is running now with above on dc/dc's 10c to 15c less tempature with the copper heatsinks and a 3000 rpm fan vs their 1500 rpm fan (20% more noise) and also there is a lot of folk

that can fix and revive cubes.....now In other words my temps etc and stability have never been better ....after the above mods I was running the ones I have here in the basement

at lower temps when it was 84F this summer then the previous winter at 60F.....I actually gained 50mh total plus on the conversion...the dies that are down are still down but now all else

the last 6 months is solid it seems (again to your point working around some dies that are down)

Then again used Titan equipment (if it ever shows its unicorn hoofs again) might be more of a risk then the A4 ..people tend to move the shaky stuff in used asic's etc and to your point
you are not sure what you are getting and it is over priced...probably because the stuff for sale is unmofied (from what I've seen) and thus let the bidding wars begin from those
who know how to fix/tweak them above

But the point of failure on folks running Titans now has improved from the above hacks dramatically imho for extending the life of the units...hr and 1/2 mainly due to lightfoots fix of such and gen tarkin's firmware....the mods are damn helpful for long term life too temp wise decrease

Hopefully a community of cooperation etc will come up for your A4's as they chug along..and extend improve their life too as time goes on...but working great for me so far

So you are correct Titans WERE flaky and had issues in 2014 (nov in my case 2 dead dies on orig unit) BUT (not counting the summer knc liquidation yeech) IF you have a Titan that works now very likely it iis over the hump and will work just fine for the next 2 years...especially with the gen tarkin firmware and repasting all mentioned above

As an example I have a buddy with 40 titans or so that are rock solid (some modded some not) you can work around the dead dies on some and the rest is stable

heck I may even get some of my problem dies fixed by lightfoot (dare to dream have enough hash now I can send in some 1/2 working stuff for the heck of it on a hope)

Anyway all the Titan stuff that has junked out has probably been that way for the last year....the shot stuff is off the market whatever the amount that is from 2 years on
..there is new life in them now ....at least it seems so from my side and my buddy with above mods

HOPEFULLY your A4 will also be solid like the A2......I may still get one or two...(with my hash that is 1 month hashing lost to pay off an A4) But likely I will wait

see if the warranty improves or how the firmware is etc..if it costs me 200-300 more a unit and I lose some too difficulty by waiting a month or two .. so be it...but even if the A4 was golden child....at a  12 month plus ROI right now and again that pesky 45 day warranty ..I'd likely wait anyway ......as to folk the must/need/want to jump into scrypt mining in a big way

and get multiple A4's on a price pump hope of BTC and say LTC floating along onward and upward..tough choice...I did that back in the day got lucky...but scary bet

but as they say big risk big reward or big risk low reward...seems this kinda thing always shoots to the edge and either flies upward or falls off the edge downward

I may still get on board..but right now too many moving parts (firmware? 45 day warranty? 12 month ROI) .....then again not a lot of Titan cubes floating around I can repaste

and fix either So anyway wish all luck on the A4 but sitting on the fence now

Given the A4 specs a "1000 watt power supply", which will probably be pulling somewhat less than that in actual usage, where the HELL are you comming up with that 1100 watt claim?


 Yes, the Titans are fairly close on efficiency - they'll probably stay profitable for the forseable future unless you have REAL high electric rates - but they're not nearly as close on efficiency as you seem to think, *AND* their track record of many dead cubes makes their reliability very suspect while the A2 was rock solid for almost EVERYONE that ever used one.


 I can see a day, probably in the next 2 years likely less, when the A2 becomed non-profitable at 3c/KWH electric and the Scrypt miner market becomes basically a 2 horse race betwen the A4 and Titan - but those Titans that are still running by then will definitely be the LAGGING horse in the race.

With gen trakin 3rd party firmware I get 300mh at 1225 watts so hardly that big a diff at 280mh at 1100 watts .......big whoop.....my Titans can run just fine with
your equipment into the future at that spread.....main problem is electric prices to the wall ..in USA 12c kwh is average..mine is 14c kwh...that is real issue with home mining

I was mistaken on the amount of A4 boards involved however.....how what is pricing for repair of 'likely' troubles on such boards after 45 days ...ship them back to china or any electronics
tech in the states MAYBE LIKELY  to fix any issues? Pointing out likely fail points and 3rd party electronics technicans ahead of time and LIKELY STUFF to fail and LIKELY it could
be repaired reasonably by folk other then A4's being shipped back to China .might go a long way to help your sales....

 I'd believe your hype a lot better at 180 days for a warranty rather then 45 days..that is pretty lame imho.....does not show a lot of confidence in your equipment consumer wise
again my view..

good luck anyway my stuff has all ROI'd so hopefully even with a 25% difficulty rise or more  in LTC and/or scrypt coins with more equipment in the world a BTC and hopefully LTC and other scrypt coin, a pump in price is really what we need (or you need) to get over the A4's over 12 month ROI hurdle....

IF such a pump happens in the next few months then ...all is said and done it won't matter much....right now the 1 year plus ROI looks kinda tough thou LTC wise so I guess everyones bet (titan A4 or whatever) the price of LTC and scrypt coins makes purchasing most scrypt equipment a shaky bet at the present time

We will just have to see if your product hangs together or has teething issues like MOST ASIC machines either BTC or LTC did...ie 3 months of firmware issues etc etc bad dies etc etc

so anyway 45 day warranty is really what stops me from getting your product ..at least one.....so I'll fence sit for now ...and see how you do out of the gate...if as I said above

we get some price increases in scrypt coins and ltc in the next few months...I'll look at this again...anyway my 2c worth

(but then again what do I know at one time I drank the BFL Kool Aid.....got a refund..but still was on the bandwagon don't ya know)



is a price pump to keep the gerbel wheels moving on mining

The web site update is talking about A4's that will hash at a much higher rate than 280mhs of batch 1.  Is that going to be part of batch 2?  We have heard dates of Dec as batch 2.  Is that correct? Thanks.

Less talk and more shipping of miners 

Follow your logics: each 14nm a4 miner has 2 units and 4 boards, any board goes, others will work! Even after 45 days warranty, it still can be repaired at a reasonable cost. It has more than 3 times power efficient than bankrupted knc Titian.  A4 is the next gen, best ever. 

Innosilicon A2 was the most reliable miners in the ltc market and A4 will be a few times better, wait and see! 

Have you ever even read our presale announcement? Our miner spec is 280Mhs per a4 miner if you follow our pre order announcement, 500mhs a4 miner needs a lot more chips at a different price.

Just a reminder: fact speaks louder. Biggest a2 miner ever available was 110mhs, yet a4 miner starts at 280mhs with a 25% smaller power supply, come on, get the fact straight! a4 is a completely different animal with more than 3 times efficiency, not to say more power saving can be achieved with just a software control at lower voltage. If you want 500mhs miner, buy 2 a4 miners and drop voltage and clock rate, you can squeeze 500mhs with one power supply.

As with all mining hardware, pricing on these is a horrible ripoff.     But... at least its a tiny bit better than anything in SHA land. For now, I have no plans on buying an A4 ... 1 year to *maybe* ROI is insane.

Got to say from the specs on these units...gonna take a 'massive amount" to upend my Titan apple carts.......just saying....I suppose if enough of them work for a year and flood the market.

looks now like spec wise it is pretty much oranges vs oranges eff and mhs wise all in all

the main advantage with a Titan right now is if one of 5 cubes goes you still have 4 cubes (and hopefully lightfoot to fix the broke one) ..with the A4 if the board goes after

45 days you are skunked...(again unless lightfoot changes vendors)

Still,  if you believe in an eventual BTC pump to 800 bucks plus and LTC or scrypt coins to follow ..you could get one of these for a gamble ..but right how using this calc

www.lightcoinpool.org

I get a bit less than a year ROI at 12c kwh (winter 11c and summer 14c kwh ave) ...so the gamble is on a pump an mining paying off I guess

Then again an 800 buck BTC pump with LTC at 0006 btc to usd would be 4.80 usd LTC

one of these miners COULD climb out of that hole even with difficulty...but again if they flood the market even at the above rate would probably again reset to s year ROI anyway

 Delays of more than a YEAR = "just fine"?

 Interesting concept that - and I'm not even going to START on the many other issues with KNC that drove them to bankrupcy despite their own in-house massive mining efforts.

'You will see Innosilicon is damn serious in fulfilling our promises.'
Are you joking or are you serious now ? You announced 500mhs miner at 1000w and you reproduce the A2 at 130Mhs
So you just care how to make money and not about your investors if they are any  
11KG ? this is a step in front ? did you see Baikal miner ?
