I did both

Well I can say one difference is #xnsub now works perfect out of the box and its cgminer 4.8.0 now =) woot
Good job!

Hrm... I just hit the upgrade firmware button and it nabbed verison 2.6.1 .... any posted differences of this somewhere?

I was thinking about that, but thats a really aggressive use for that setting. I prefer to use that setting if one of the ASICs stops mining all together or a majority of them. But, Ill ponder it further ... if it ends up bothering me enough lol!

I dont wanna go through that hassle n downtime, Ill just manually reboot it every once in a while if thats what it takes ... or make a cron script or something... I ono

I dont know if this has been mentioned in the thread yet, but regarding the topic....

Its true to a point. Miners nowadays are being forced to cash out a much larger portion of btc mined than theyve ever had to historically.
While the rate of coins mined stays roughly unchanged. The simple fact that theres MW's upon MW's of power that the large farms have to pay every month, means they have to cash out a shitload of coins, they get dumped on the exchange and forces price even lower.
Obviously this is outpacing demand substantially, otherwise the market would just buy it all right back up. This also causes an avalanching effect as the price gets lower and lower, because the miners have to cash out more and more coins.

Back in the 2011 days, miners werent forced to cash out such a large portion due to electricity costs, sure there were farms here n there that did have to do it ... but because there were so many garage miners / hobbyist miners that participated, most of us just hoarded the coins.

The mining landscape is vastly different now ...


But that doesnt change the fact that demand is substantially lacking in BTC at the moment, this is the true reason for its price decline. Another china like bubble hasnt come along yet from a different country, in fact the china bubble may be its last 'holy shit this part of the world has just found out bout btc...' type bubble ever to happen. Whats needed from here on out is a solid merchant acceptance foundation(which it has grown substantially since the years previous), consumer demand(which is nearly flatlined) OR... a major country's currency to go belly up and citizens flock into safe havens, like precious metals / bitcoin .. etc..(which is only a matter of time).

As bitcoin continues to go down, miners n farms will shutdown, diff will drop drastically ... which opens up Bitcoin to its Achilles Heal - being 51% attacked. Thats probably what scares me the most at this point. If people just start 51% it at will... 'The experiment' will have failed.

What pisses me off further is the devs just have ignored the 51% problem, relying on peoples good hearts at a few points in Bitcoins past and now its price fallout and possible subsequent 51% exploitations happening all the time... will be the ultimate example of irresponsibility destroying something potentially revolutionary. 

I highly doubt its temperature related. All the time, all ASICs cept maybe 2 read 85C, 2 of them ... some of the time are between 105C ... those dont get throttled down tho, its the cooler ones that seem to .. I dont get it.

It seems like some of the voltages are getting raise and clocks are being dropped to keep under 210w, but that makes no sense... why would the volts get raised a tiny bit over the course of days, if the chips are already stable (no hw errors) ... etc...

210w limit per board, voltage start 685, limit 699, temps never hit over 105c

So, why does every day that goes by my SP20 keeps clocking itself a tad lower ... losing like 3GH-5GH/day ... and never goes back up? ... unless I restart mining...

Try: "W:127.0.01,W:192.168.1.0/24,W:192.168.1/24"

I had to put both versions in my config to get it workin... yeah, its weird, dont know which one really works haha

oh so 4.8 is required? psh... need a firmware upgrade =/ or howto on changing lol

I tested exactly like that, it doesnt work.

reread my post ... I updated to latest firmware =P
2.5.64 according to my miner...

In settings->flag ... I have in that box 2

but it doesnt work

Question, how do you get extranonce subscribe to work on latest firmware?
Under settings I have 2 set in the FLAG box..

I put #xnsub after my westhash pool in the gui and it just stays in a dead state.
If I take off the #xnsub its alive.
Ive tried restarting the miner entirely as well, no change.

Wow, thats incredible!

Hrm... well maybe there is a bug or my hardware is perfect...haha!
I run mine at 1450GH, .699v max ... 210w max each 'board'

hrm... I did, it shows 0 ... thats a total runtime error stat??!?!?! how is 0 possible?! Ive never had an ASIC be truely 0% unless it was a severely underclocked S1 LOL!
What does this stat refer to then? I assumed it had something to do w/ rolling hw rates ... (sw:3, hw:3)!

but nonetheless if hw-err:0 is indeed true, then Im even more impressed w/ this miner now!

Also, what does BIST refer too and what does bist-fail mean? I see bist listed all over the place lol

I doubt its 0, thats just cgminer's default HW reporting field, my avy3 module didnt report its errors to this field either, it reported it in a custom field.
If you go to asic stats page on the miner itself, u can see it counting HW errors, but theres no HW error total stat, from what I can tell anyways...

This review is gonna be simple, just gonna notate some things that impress me and other things it falls a bit short.

First of all, its been running a good 24hrs, this is one impressive miner!

Its amazing that you can specify a maximum wattage consumption per board (4 boards) and it will adjust clocks / volts over time to stay under that limit, it even takes environmental conditions into account such as temperature to keep the ASIC's happy. If you dont wanna limit their power consumption, u can set the power consumption really high and control them via a voltage range.
Also, you can let it 'autolearn' your PSU's limits, Im not sure how this is achieved, it doesnt seem to know what my PSU is to begin with... supposedly it can figure what some PSU's are... Im kinda afraid to try it rofl!
But, if it was as sophisticated as measuring ripple over wattage increase or some other electrical thing that takes place when PSU's hit their max... that would be impressive!

The ASIC status is one of the more impressive ones Ive seen, it shows wattage per board, per ASIC chip, VRM consumption. It shows amperage per ASIC.

The fan is statically set at a speed by the user, temp limits out of the box are statically set, they can be adjusted through console. Basically this is one of those devices where u set a fan speed and it does the rest to keep the ASIC's in check.

It also features over the web firmware upgrades - I upgraded mine w/o a hitch, and some added features include extranonce subscribe support, for those of u who rent over at NH / WH =)

I think the myminer.io central control of miners on ur local subnet is pretty awesome. Im gonna assume this is how it works: the miner kinda acts like a teamviewer client, it reports to a central server very basic info like model, local ip, firmware and a bit of other stuff. So, if u have a huge farm ... u can easily get into their interfaces by just going to that website without having to try to dig around in ur firewall for the miners ip.
I believe its similar to bitmains recent remote control feature of the S5 (I forget its name).

I run mine around 1.5TH just because its very effecient, approaches .62w/GH @ wall @ 120v AC
I went as low as 1.4TH and iirc was .56w/GH @ wall
Tests done on GOLD PSU

Some of its downfalls, there arent many...
Im not sure where to find its actual HW% since that stat is not exposed obviously in their ASIC stats page or in cgminer's API.... if someone knows, that would be great =)
Fan noise, unless u run these severely underclocked, they wont work well as a living room miner. But I believe their is a fan silence mod u can do to them...somewhere on the forums...

That about sums it up! Overall extremely impressed!

oh fuck... I missed =(
