A4 Dominator - Pre-Order Group Buy - 280mh, roughly 1000w, $1800 + shipping

[usao]

When I was trying to get Titan to work, I used single G1600.
I wasn't sure how reliable hooking 2 different PSU's into the Y-splitter would work.
Ive heard some people had success, but it's not recommended on forums such as tomshardware and others who talk about feedback and un-reliable/stability issues with such a config. They also talk about blowing out one or both PSU's when wiring in parallel.

Again I have not pulled the trigger on an A4 but doing the numbers I get this. (I am using the free below calculator to do so)

www.litecoinpool.org/calc


I'm using the following figures (hosting 12c kwh w/fees) at 280mh and 1000 watts (been my experience asic's always run higher watts then the specs)
at $4.10 LTC price I get the following

A4 price of with shipping ($2,000 usd?) add MY dual 2560 server platinum psu rigs for total of 300 bucks (maybe double that if 2 psu's at your end) I get $2300 complete.

the link to the hack to do so below ..and you can either get a heavy duty backplate (15awg) or just add your own as a previous poster mentioned to make such 15awg when
modding the backplate.

24 hours   2.80509961 LTC   11.50 USD   2.88 USD   8.62 USD
7 days   19.63569727 LTC   80.51 USD   20.16 USD   60.35 USD
30 days   84.15298828 LTC   345.03 USD   86.40 USD   258.63 USD

So ASSUMING by some chance difficulty was to remain the same (snicker) or maybe by circumstances of LTC price and difficulty rise balancing out to the same (snicker snicker)

I get 8.89 months for ROI.....

Kinda ugly ...and my server psu rig is 1/2 the cost of what I'd get instead ..that is 2 corsair 1200i's at 300 usd each Newegg (on their monthly sale) so sheesh...MAYBE you could
run this beastie with ONE PSU..my experience with Titans I'd rather run 2 Corsair 1200i's and over kill with their 16awg wires running 1/2 and KNC PSU splitters additional protection.
A corsair 860i would probably be over kill but I have Titans and switch around so would need the Corsair 1200i's etc in case if not running the above server psu hack in the Jupiter case.
Thus my savings of 300 over what I'd spend ..just saying..

With the expected difficulty rise in LTC from the A4's and the sale to the big boy data halls before us (investors they got) we need a heck of a lot better price point then $4.10 ltc imho

anyway just my view on pondering this...but damn we need BTC to pump and LTC to follow damn it !

I think it would be foolish to purchase gear like this just to mine LTC.  You won't make any significant money - if any. 

On the other hand -- this could provide great opportunities when mining other coins -- if you are good at buying and selling.

Those A2s still look good to me.  I may have to pull those heavy suckers out of storage and set up another farm.

Are you saying that you have them dormant at the moment? Wouldn't people have miners running all the time to make at least something from some coin?

[usao]

Exactly, I have my stuff running all the time. The only rigs I have decommissioned are those which can't produce enough return to pay for their electricity.
The A2 is not yet at that point, and the A4 is significantly above that point.
Why just have the miners sitting idle. If elect is too expensive in your area, then you should cash-in on the resale value of the HW.

Mining has always been a hobby for me -- but my time right now is focused on my business.

Makes sense. Sounds like you've got your priorities right taking the attitude of hobby, beer money etc coz there is not a lot you can control really and lots of variables.

For me, I find the learning/educational aspect of the technology amazing. People making electronics to effective "print" money or generate this "thing" that you can exchange for real stuff. Imagine explaining that to your grandma!

[hdmediaservices]

I am right with you.  It still boggles my mind how this all came to be so quickly and is continuing to be even more relevant each day.

It is definitely not something I count on for any real money.  Some people play golf -- I like to mine and trade scrypt coins - lol. 

Problem is that I think others look at mining as easy money and it can be very addicting -- practically like gambling. 

You won't get rich from this unless you have the funds and know how to be a key player.

Does not apply to Titans need 2 psu's of imho at least 860 platinum and above and the y adopters that is the deaf to standard for titans. All working units I know run this way unless you use my server hack

Try this free LTC calculator - it takes into account the change in difficulty and provides a detailed report on expected return.  A much better "what if" approach.

yeah...lol I've seen it before.but I never know what to put in for diff rises etc for the calc to work correctly in my view...I figure as long as I'm a guessing anyway...just do it
with the litecoinpool calc...as a no diff rise option..then I just guess 25%/30% diff rise at whatever end time I'm looking at from 3 months to a year

ie I just wing it

now what would are you using for your calcs with the above...I'm always willing to be schooled..but again I look at your calc an scratch my head...so far winging it

as a guess of future difficulty added to my hash of a guess has been pretty close in 20/20 hindsight

but anyway lay out your method with the above here for us to ponder as well using say the A4 hash etc and say you got it the 15th of Sept say

If we limit the measurement of scrypt network hashrate to coins at coinwarz.com, at this moment only, there's about 5,100GH/s for all scrypt coins in the "universe".
http://www.coinwarz.com/cryptocurrency/?sha256hr=9460.00&sha256p=2600.00&sha256pc=0.1000&sha256c=false&scrypthr=110000.00&scryptp=1000.00&scryptpc=0.1000&scryptc=true&x11hr=34.40&x11p=600.00&x11pc=0.1000&x11c=false&keccakhr=1000.00&keccakp=600.00&keccakpc=0.1000&keccakc=false&quarkhr=20000.00&quarkp=600.00&quarkpc=0.1000&quarkc=false&groestlhr=45.00&groestlp=825.00&groestlpc=0.1000&groestlc=false&blake256hr=11.20&blake256p=600.00&blake256pc=0.1000&blake256c=false&neoscrypthr=400.00&neoscryptp=400.00&neoscryptpc=0.1000&neoscryptc=false&lyra2rev2hr=30.00&lyra2rev2p=600.00&lyra2rev2pc=0.1000&lyra2rev2c=false&cryptonighthr=1950.00&cryptonightp=750.00&cryptonightpc=0.1000&cryptonightc=false&ethashhr=108.00&ethashp=600.00&ethashpc=0.1000&ethashc=false&e=Coinbase

Torturing that logic, LTC is about 31% of the total network hashrate.  Now if we look at the known pre-orders for the A4, we have about 21GH/s being added so we then allocate 31% of that number (6.51GH/s) to LTC.  

Now using the the litecoin difficulty from bitcoinwisdom and project the addition of the 6.51 GH/s to the 1.6 TH/s network hashrate you have less than 1% addition to network and thus a small bump in difficulty.  If you put ALL the new hashrate to LTC you would only bump the network rate up ~1%
https://bitcoinwisdom.com/litecoin/difficulty

The big unknown as far as projecting difficulty increases for LTC (and the LTC calculator) will be the rate of release of new machines into the market by Innosilicon and we have no idea of their production capacity.  

Based on the limited assumptions above, to double the entire scrypt universe network hashrate, Innosilicon would need to release about 18,000 new machines at 280MH/machine.





 

[wlefever]

I see no reason why they can't produce 1,000 A4 machines.  280 GH/s added to the Scrypt network not necessarily just to LTC is possible IMO.

[usao]

Off the wall question...
What's involved in figuring out how to buy the chips directly and implement a small-ish miner with just a few chips?
What type of circuit engineering is needed? Is anyone thinknig about a small rig implementation?
I do not have any clue what would be involved, but it seems it would be an interesting idea, for those who don't want/need a large piece of gear but would prefer to have a much smaller desktop rig based on the A4 chip.
Are there any companies who buy the chips and implement their own circuit boards?

Do you know how many A2s they've produced in the past?  That would help with projections....

I think you're looking for an Original Design Manufacturer and I've looked before and couldn't find one (other than those who claim they can in Alibaba).  There are certainly EEs out there who have made small batch machines like the FutureBit Moonlander but I can't find a commercial service.

[usao]

Thanks, I just think there could be a market for smaller machines which don't require such a high degree of investment or power requirements.
It might open up the market to a broader base of miners...

No I do not.  But took a stab at what I think is a realistic number considering they were looking for $1.5 Million USD for partners.

On a side note what is the expected shipping cost per unit through DHL?  The estimate I just tried to find out seemed WAY high around $450. 

[usao]

i think the shipping will depend on volume to a single location.

[Longsnowsm]

You should ping Chloe and ask her based on your location and number of miners what the shipping estimate will be.  

[usao]

I wasn't going to rush them, since they already said that shipping would be figured closer to actual distribution.
I think if I haven't heard back by mid Aug, ill probably drop a note by then.
