Im interested to know whats going on here.

Ive heard of other people having this issue lately. Could it be new firmwares that are being made to stop miners ? Since the older cards never had these issues, it seems it only happens on newer batches of cards.

Mine has 3 power connecters.

I dont recall ever being able to get it to work with CGMiner, but i was using Linux and PCI-Express

Im guessing if you use Windows (10 ?) and USB it will work with CG Miner then ?

Thats good info !

Is there anyway of easily checking the firmware version ? I cant remember what stickers or anything being on the card.
If its the second version i might as well fire it up on CGMiner just to get some heat into the fluid, if its the first version that only works on BFG 4.2, ill just power it up and let it run, is 4.2 even compatible with the current fork of BTC ?

I think mine has the firmware that doesnt work with CGMiner.

Is there anyway to change it ?

I know its not worth using, i just want to fire it up for nostalgia reasons. Also back in the day i ran it underclocked at just under 400GH and i was able to run it on a ~300W PSU very quietly for almost a year.

Is anybody still running theres ?

I still have my 750GH dual water cooled unit in near mint condition in the closes. I collect rare computer parts so when i retired it i thought it was too well made and nice looking to get rid off.

Id like to fire it up again just to get the pumps and fluid going, but i doubt it would work with any of the currrent versions of BTC miners or windows. And im not sure of the older miners that support the Monarchs will work with the current forks of BTC.

And i see lightfoot still has vast knowledge of these cards , he and kano helped me get mine running all those years ago. I really liked these, and I i really wish BFL was a better run company because they offered some truly unique products.

I assume you are talking about Dogecoin ?

Yeah its a crossfire board, so i might consider trying to find two cards that will get good hash on the cheap. Problem is this board is ancient PCI-E x16 1.0 , newer cards might not POST on this thing.

Monero sounds good. I was thinking of Dogecoin, but I always felt that its kinda looked at as being a jokecoin.

*Monero doesnt seem to list the HD4870 as being able to mine.

Hi Guys

I have an old server that I was going to sell, but Im thinking I can use it to mine some alt. Im not really interested in profit or cost of running it. I just want to be able to mine some coin thats not complete junk, and it will be nice to get more than tiny fractions every month.

Spec:
Athlon64 X2 4400+
2GB ECC DDR
512MB ATI Radeon HD4870
160GB HDD
Ubuntu Linux

So what can this mine ? and am I going to have a hard time finding mining soft that will still work on a HD4870 ?

I was thinking DCRED but that seems to be on the rise, and gominer/cgminer doesnt seem to support the HD4870 ?

Cheers in advance for any advice!

Can you underclock in that version ?

Is there a chance that the limit for dust payments is going to decrease since after halving its easy to be below the dust limit.

I know its no longer feasible to mine with less than 1TH these days but i still like to mine for fun

Not, not running a node for this reason, but ive got a bandwidth problem regardless its seems. Need to figure out why its happening all of a sudden. Might not be the Antminers fault.

How much data are your guys S3's using in a month with the current block settings ?

I have a something on my network thats using 5GB a day now, and its just a PC and two miners, and the PC isnt the culprit i checked already but not sure how much data the miners are using but it shouldnt be that high, it used to be a couple hundred MB.

Not sure if the stats in the antminer log the total data statistics, seems to only show realtime.

I don't agree at all with this, lower price affects the big companies more. Sure they can mine at lower cost per TH than a hobbyist, but a big company cannot mine at a loss for any sustainable period because they are in it for profit only, they lose millions when they mine at a loss due t sheer scale of overhead costs. They have no intention to support the network so they can only mine at loss long enough to hope they can ride it out.

A hobbyist miner mines at an insanely high cost per TH by comparison, in most cases they are close to break even or loss. But the loss is a few dollars a month, something that any hobbyist miner with another income can sustain indefinitely, since they mine for fun and for the support of the concept.

Now a small business miner is a different story from a hobbyist, guys who have a few hundred TH trying to make a profit, this is a dead/dying group these guys simply will not survive any low BTC values, their cost is much higher than a big mining company that is making its own hardware yet they are also mining as a business. They have no choice but to wait until the huge corps allow them to buy more efficient hardware.

As a hobbyist myself, i actually would love the BTC rate to plummet, cause i can run at a loss for as long as i want, and it will be pretty entertaining to see the big greedy Chinese corps struggle to stay afloat at sustained low prices. BTC will never die, the worst that can happen is that it falls out of favour with big business (the same people that are destroying the network anyway and also refusing to sell us hardware to compete with them as a truely free digital economy and distribute the network as Satoshi intended).

Can somebody explain to me why we are getting the occasional 30min block on the network these days ?
I thought the difficulty target was for 10min ?

Also the more blocks we can pick up when the big pools have issues.

Thanks, very interesting

I dont have one, i would have tried it and posted the results no problem if i did

How low can they be clocked from the firmware ?

Id like to know what the S7s consumption at the wall at its lowest setting.

Profitable home mining may become a myth, but home mining won't die. If it did, Bitcoin would slowly die, since the real believers of Bitcoin are the home miners and hobbyists, students and researchers. These are the people that actually give Bitcoin value.

The farms in China and the investors behind them know very little about the bitcoin ecosystem by comparison, and they do things and act in a manner that is actually harmful to the future of bitcoin (decentralisation, SPV mining, mining empty blocks, pump and dump, monopoly of control of hardware, and harm to the environment, money laundering, ponzi schemes, and mining with customer pre-orders). They are very much in it for the short term, trying to milk as much money as possible from it so that they can divest into other technology areas once they have killed the bitcoin cow.

Home miners were mining before Bitcoin had any real value, and they will still be mining at crazy difficulty without any hope of profit provided the network is healthy. Home miners stopping in droves would be a very VERY bad sign, since it would mean that the people who understand the technology the most and are the most die hard supporters of Satoshi's vision, have lost faith in the network. That would be far far worse IMO than any crazy high difficulty level or electricity cost.
