Topic: A4 Dominator - Pre-Order Group Buy - 280mh, roughly 1000w, $1800 + shipping - page 13. (Read 122577 times)

The payout values at Prohashing and Clevermining are both after fees have been deducted, so on the days they pay out 110% of LTC you're loosing 7% and the days they pay out 130% of LTC you're loosing 27%.

If you want to 'hold and dump', Prohashing will pay you out in any combination of 180 coins in the ratio you choose, including LTC so you can still hold and sell when you see fit, the difference being you could be earning more LTC per day by mining multi coins that are more profitable that day. At the moment I'm being paid out in Monero because the price has been falling and like you I intend to hold them until the price recovers. Next week I may choose Zcash.

I looked at using WhatToMine to decide where to point my miners in an attempt to save the 5% but in the end worked out that it's way simpler and more profitable to rely on the algo that ProHashing use.

I have noticed a huge difference since my re-flash I have Batch 1 and a single batch 2. I am not only stable on litcoinpool now but I am getting very close to the advertised hashrate. On the chart the little spikes are above spec the bottoms of the spike are a tad lower then spec.
Before I got flashed the best I could get on litecoinpool was 245mhs on the set of cubes now I am getting 270Mhs as seen in the graph the total the top line is like 410Mhs most the time.. I have 3 miners so that is 137Mhs each cube more or less.. Also before the re-flash I was still getting many re-boots on litecoinpool but now 8 days straight running it is very smooth.. I saw no difference between litecoinpool and PH payouts.

All custom. Postgresql running on RPI, scrips looks at returns from pool API's, determines best 5-minute average return and current return, and pushes the change to the A4 using web port. Fortunately the A4 dosent require any authentication or it would be more difficult.

I would love to know how to setup a database to do the switching.  Is there a tutorial or something online for how to do that? 

Yea, returns are all over the place.
Much of yesterday Nicehash was paying significantly over LTC, overnight I was working well on hash-to-coins, now Nicehash is back paying 0.04 BTC/GH/Day...
Normally the returns are a lot more stable, but past several days have been crazy.
Good thing mine are controlled via a postgres database, doing auto switching of my returns would have been crap the past few days.

Looks like 4-5% increase in diff again after 2 days

Me I have Titans so (up until now with this price may change mind) not worth the  trouble to multipool in that litecoinpool no fee (save 5% multipool fee) and pays out at
103% (so that is 8% savings right there)

Again at these prices IF you have machines that can hack fast switching coins and/or multipools go for it...me I just find if I time when I switch my LTC to BTC when the
ratio is right..it all kinda works out the same (hoard and dump)

Tough sometimes to figure out which works best with btc price up/down/sideways and then the LTC to BTC ratio actually got way better when it dumped to 800 from 1177 btc that is

all very 'voodoo like' imho

All I know is 2 months ago my 3150 mh or just before the A4's really got to shipping I was making 2330 a month after electric etc..now it is 1330 ......

We all need a price pump for LTC and/or other alts to follow or this is all gonna go to the fate of Scrypt-N coins (ask the oldsters about that ..Titan miners were made to
mine scrypt-N asic resistant coins...they did so and blew up the coins in a couple weeks..thus no more scrypt-N ..if you blow difficulty up too fast and the coin has no way
to recover/for use or whatever.....POOF...)

But I mean really..the price of LTC was over 3 bucks at the first of the year BEFORE BTC halving for crying out loud..we need to catch a break on LTC ..this is not looking all that hot.

Watching the LTC difficulty rise (its a sickness) is my new 'morbid' hobby

Looks stable. But even older versions worked well when mining single coin and seperate pool. Autoswitches gave it problem.

My graph After 7 days mining non stop 3 cubes total on litecoinpool

Thanks very much, Eyedol. The next person has received the Jig yesterday.
Really appreciate your maintenance for the Jig 

Update of the Jig delivery in USA:
1. the next delivery of Jig will be finished soon for the rest 4 users
2. we will ship another Jig from Europe to USA soon

Hi Eyedol,

From the feedback of our customer who use v2.0.2beta, the performance of the A4 is stable without reboots issues. So something is wrong here.

Just curious that you can access to the SSH because till now we didn't open source. Please DON'T CHANGE CODE RANDOMLY. Because we don't know what will happen when you changed the code on your side.

For now, please get the Pi restarted first then try the new SD card.
We are glad to help if you need.

Looks like Pi going nuts. Did you try reseting it with  button? If new SD card and PI reset doesnt help, probably PI broken.

Another Update.

So after about 2-3 Hours of working normally after this post, the A4 went down again and started boot looping every 5 mins or so. I didn't have opportunity to check on it overnight and the next morning I found it completely offline and the Pi unable to be reached via ping, ssh, or accessible via web interface.

I power-cycled the entire unit and it came back online normally. Within 5 minutes, it rebooted again. I got the A4 back up and stopped mining. I changed the speed to 1000mhz and started it mining, rebooted again within 5 mins.

I want to stress this is the Pi rebooting for what appears to be a script going off, the A4 appears to be hashing normally when it happens.

I reapplied all the settings, set everything to 1200mhz, typed back in my pool information, added a 3rd pool and started mining again.

Now its be running for over 9 hours on PH without an issue. 

I've got new SD cards coming today and I'm going to replace the one in the Pi with a fresh 2.0.2 image/sd card the next time it goes down again.

I'm fairly certain at this point that I have not seen the end of this issue.

I reached out to Inno for assistance in steps I can take if this issue persists after I replace the SD Card / Image.

I have to agree with you. My guess would be that they are not selling nearly enough and with the $100 off (lol) I'd guess we won't see batch 2 too soon. Pretty sad really, because ad you say it seems there are newbies buying these units..

A4, 280Mhs, the most powerful miner in the market! Last batch clearance price before 21st Jan.! Buy from http://www.innosilicon.com/html/a4-miner/

Heh..they are soooooo clueless. (Hell, what do I know they may be selling them to newbies like hotcakes)

You pretty much nailed it. Here is their reply

Hello,

The clearance sale of A4 before Jan 21st is $1700（$100 off the list price） per unit plus shipping fee.

A WHOPPING 100 bucks OFF the price of ..what was it 3 months ago?

sheesh..it is either they are selling very few...or selling lots to a newbie crowd..I see no real in between.

Probably to 1780 or something

Supposedly the A4's dropped in price...or so the site says. They don't list it. Anyone know yet. *just curious don't plan
on getting any*

After reflash or B3 everything works more or less ok. Worse case need hard restart takes 30 secs to start up again. At least no boards have died yet.

I get that, but there's still be problem with stability, there has been a lot of problems throughout this thread with cards dropping, getting up to 50Mh/s less than advertised, close to no response from inno on these issues etc. I know that there is the problem with help/spare parts with bitmain, but so far this does not seem like that much of a better choice in those departments.
