    Both second hand on adverts.ie. I got them too cheap, the sellers were gamers not miners and they weren't aware of the recent inflation in GPUs suitable for mining :p

    Nice one, I had a look on adverts but didn't see anything worthwhile.

    Anyone here mining sia (dual mine with ethereum) on nanopool? My miner is hashing away on both eth/sia but only my ethereum balance has increased in the last 24 hours.

    My sia balance has been stuck at the same value for the last 24 hours

    I mine on nanopool and I regularly have a look at my hash rates. Checked today several times and everything was fine. I find nanopool to be very reliable (far better than ethermine, with whom I started as they're the biggest). I've had the odd time where they didn't pay out very soon after reaching my minimum payout. One time I contacted support and they got back to me within a day with apologies and explaining it had been so busy, payments were a bit delayed. I was so impressed with nanopool that I sent them a few days worth of mining in exchange for a few tokens :)

    Absolutely. I'm typing this from my main PC running W10 Pro at the moment with the R9 390 at full mining speed (for the last 131 hours). I can even watch 4k movies through my on board Intel HD graphics no bother. I've not run ubuntu and mined at the same time, but I presume it's the same in any general purpose Linux distro.

    What sort of return have you made in the that time ?

    That's one card hashing at 29MH/s for 5.5 days solid. According to one of the profitability calculators, that would have made me €17

    Have you decided to start holding the ETH you mine yet or still selling it straight away Unkel? Your returns must be way up whatever you're doing.

    My strategy when I decided to go mining was to sell immediately. This was a very low risk strategy (worst case scenario - a total collapse of all crypto currencies => a bit of depreciation on the graphics cards and a write-off of some low value bits and pieces like riser cards, cables, etc.). I have stuck to my plan.

    With hindsight, I would have obviously made a tidy sum if I had HODL the ETH I mined :)

    I'm just grateful that, despite the increase in difficulty, my mining revenue is a bit more now with ETH at over $1000 when I made my analysis and ROI timing calculations and decided to go mining based on the average rate of about $300 in the few months before I started

    Out of interest what is your plan when ethereum goes from pow to pos? I’m also mining ethereum but I will be looking at decent alternatives late summer of this year

    This is turning into an I'm mining Cryptocurrency, AMA :D

    ETH isn't even the most profitable coin to mine at the moment. It's a big coin and and at that a reasonably solid one. When the switch to POS happens, I'll mine another coin :)

    I'm looking forward to installing Solar PV panels on my roof in the next few months. I already have 40 solar tubes heating my hot water from the sun and our family car is an EV zero emissions vehicle...

    And I'm nowhere near making back the money I invested in gpus and other bits. If the revenue comes calling, I will claim money back :)

    I'm loving it as a hobby anyway. And I will do my best to make it as renewable as I can. Next stop - as much solar PV as my 100% south facing roof will take.

    Hi All,

    I know of a PC dismantler and I was just wondering if there is a list of popular cards that he should keep an eye out from a mining perspective.

    Thanks,
    Gary

    Doubtful. only new gpus are of any value.
    old gpus can still mine but they cost a lot in electricity for the amount of hashrate you get.
    also ram size is increasing for some coins meaning they wont work with 1 or 2 gb cards.

    Looking at an advert for the Antminer S9 at 3k euro. It's claiming 3.36 BTC per year, given current prices that sounds like a tidy profit to me.

    Pinch of salt on the 3.36 BTC claims?

    From my admittedly limited understanding once you start going into ASIC based devices such as the Antminer you're locked into specific coins and algorithms that are hard coded. The way the alts are going this could be severely limiting for a very small mining operation. While GPUs are likely to have a much slower ROI in the short term, they're effectively general purpose devices that will attract far more attention from developers and have the potential for flexibility going forward. While most of those not involved in software development think of performance improvements in hardware terms (processor speed, number of cores, available memory) the bigger improvements have actually come through new and improved algorithms. Just my opinion, but if I was going for an ASIC miner, I'd want to be confident that I could get a reasonably quick ROI as there's a greater chance it could be obsolete junk sooner. That said, as a lifelong programmer interested in getting into a bit of CUDA development, I'm entirely biased.

    In my experience a lot of the bigger manufacturers cut corners on PSUs. That said, if he happened upon a few modular corsair 850s or 1200s....

    I see that bitmain have released the antminer A3 today to compete with the Obelisk sia miner (and others)

    Bitmain A3: 815GH/s 1186w
    Obelisk: 800GH/s 500w

    I initially had one eye on the obelisk sia coin miner, batch 2 (end purchase date 31st Jan), but with the release of the new A3 from bitmain, I think I will let this one pass. A lot of talk online that the antminer A3 for siacoin will end up like the D3 for dash i.e. a decent profitability for the first few weeks, with a very sharp drop off, making it somewhat worthless within the first few months. With this in mind, I can't see how the obelisk miner, with a first batch release date in June of this year, can be anyway decently profitable. To me it looks like the Chinese bitmain producers have managed to get in there first (again).

    Links

    Bitamin A3: https://shop.bitmain.com/productDetail.htm?pid=00020180116164357365a2ljX8gx06D3

    Obelisk Miner: https://obelisk.tech/
    They have dropped their link from their wesbite for the siacoin miner (only showing decred now). It was 1599 dollars a few days ago with approx 1500 sold for batch 2. It looks to me like obelisk are attempting to speed up production to compete with bitmain, with perhaps announcing an earlier release date.

    I don't understand why the A3 should be of interest - 1.875% better performance for 237 % greater power consumption.

    Oh believe me it will be but only for first say thousand people who manage to put it online first. It make about 500$ a day but that will last only few days anyway.

    Estimated 11,000 units sold. If only half of it hit network within next 2-3 weeks (chinese miners will likely have them in 10-12 days overseas buyers add in another 7-10 days) it will render them pretty much useless in about month from now.

    Mostly because the bitmain miners will be dispatched 10 days after purchase, whereas the first batch of obelisks aren't due to be dispatched until June. By the time June rolls around there will be 10s of thousands of these antminer A3s mining siacoin

    Bitmain releases details of its new E3 Ethereum ASIC miner

    first batch already sold and limited to 1 per customer $800

    might be of interest to HoneyBadger and others.

    Wouldn’t touch it. Ethereum will hard fork like Monero did to remain ASIC resistant.

    Another tale of Bitmain running these for a few months, selling them, and then everyone who bought them being left with a miner that can’t mine on the coin they bought it for...

    It's a lot of hash rate for the money, also uses about 10% less power than a similar hashrate 6 * RX570 4GB rig. As always the PSU is not included in that price though and all these bitmain ASIC miners are far too loud to keep in your home, so no heating benefits and a bit risky to stick in your shed. And these become obsolete very quickly where conventional GPU mining rig can be sold for parts (GPUs in particular keep their value well)

    Big gamble, could pay off if you get one early. I'm not touching it.

    Anyone here water-cooled their mining rigs? I am thinking about it as it is quite hard to maintain a low temperature around my rig with 5 vega56. I wanted to use 6 vega cards but no matter what I do when I run it with 6 cards it is not stable at all. 5 cards are little better but rig restarts quite often as soon as the temperature in room rise above 19 degrees. I do have a ginormous fan under the cards but that helps only to some extent.

    Are you sure it's the temps that are the problem? What temps are your cards? Also what mining software do you use and do you specify temp stops and fan control settings? 20C-30C is a very reasonable ambient room temperature. We are lucky that way in Ireland :D

    Agreed. First thing I'd check is whether it is a specific card that is leading to the instability, or will the rig crash if any five out of your six cards are in use. If it is not a card issue, I'd then look at the PSU which might be underrated for the load, followed by the mobo. Also worth checking if the crash only happens when a given card slot is in use, which could be anything from a dry joint to dirt in around the connectors. As things get warm, you get expansion which can lead to loose joints exhibiting faults, so unplugging, cleaning and re-seating all your connectors might well help. Also, if it is a wooden frame on the rig, this expands quite a bit with heat, so leave a small bit of room for cables to move.
