Topic: Fourth alt coin thread last three got oversized. - page 2. (Read 108819 times)

All my Nanos are on ZEC with Optiminer v1.7 Linux / smOS
Optiminer has optimized it specifically for Fiji cards.
Dont waste the HBM1 memory on the Nanos on ETH
That memory type runs great on ZEC algo just like Pascal cards
having said that -- caution for Vega HBM2 users and ETH mining
you may be disappointing in the results....

This is just my mining guide nothing perfect but it keep the farm straight... 
Always have test rigs to experiment and leave the other rigs make coins

RX and GTX 1070/60 cards -- always ETH
R9 and GTX 1080ti cards -- always ZEC

Of course you can use RX to do ZEC but it will do lower hash vs a R9-390 for example by a big margin.
You can do 290 for ETH too but will use more power hence not efficient vs a RX580/480
Also using an array of 1080ti for ETH mining is impressive but not practical because its too expensive -- an RX580/480 rig can do the same job at half the price.

As far as ZEC is concerned see below -- I have tested so many combinations and standardized these to the farm.

1. EWBF ZEC is best for GTX cards

2. Optiminer ZEC is best for AMD cards on Linux

3. Claymore ZEC is best for AMD rigs on Windows.

Spoken like a True Miner.
Hope your health issues resolve soon.

thats luck fluctuating;  lower hashrates means you got the unlucky shares....   higher shows the lucky shares..  The pool as a whole is still being just as lucky as before so profitability is the same steady rise. if your machine is stable;  then im sure its just that.

Thanks for reply.

Pool is ethermine.org and this was first time ever i saw error like this. Even my telegram bot reported 0 current hash rate, but effective rate was unaffected.

Fix was to restart miner, and this issue lasted 30 minutes.

So even though zpool is saying my hash rate is way down as long as my miners are doing normal hashrate the full hash is still accepted by the pool and paid accordingly? Have been seeing this off and on for a few days now on skein. Hash drops, comes back to normal, drops again. Does that for a few hours then goes to normal running again. But have not seen the dips in the 24hr earnings graph.

which pool? Its pool code may have a bug like zpool has.

every once a while after mining miners turn into ghosts until they reconnect.


no clue why yet.


Still get active credit and overall hashrate by share reported though.

I had this morning new strange issue with another rig. All was up-time more than 50h but suddenly miner hash work was not detected by poool. My miner was still working with full hash power, without error or anything similar, but mining pool did not registered has work rate. Interesting, effective hash rate was there, but not current. Any thoughts on this? Issue was sorted with miner restart.

I think it is better to mine with safe clocks. When you have to RMA, it takes time and hurt your profit.

So I finally got all my gear and have reduced my rigs down to 2 instead of three.  I now have a one open air 4 GPU rig.  It is running on an 5 year old Motherboard with a I5 2500-k CPU.  I used to use for gaming.

It has 2 large PCI-e slots and 2 small.  I had to use 2 risers.  It is running 3x 1080ti and 1x 1080.   It produces 2500 Sol on EWBF  Three 1080ti's running at 75% tpd and 1080 running at 65% tpd.



I now plan to start a second rig with other old gear I have.  Thanks for all the help.  Has saved me alot of money not having to buy motherboards/cpu/ram.

Check out this thread and read the link.  It should answer all your questions.

I read it and I smell rotten  statement.

Or  poorly worded.

This is a click and drag  from citronick's link above.

What is the safe side of the fork?
and  if coins are placed on both forks with coins worth say Btc left fork = 2200 usd and  BTC right fork = 220 usd  is nicehash  keeping all those  220 usd coins?  since they are on the weak side of the fork

major questions  if you do a large rental near the fork.  ie don't do a large rental near the fork.

At the  time gets closer .  I will alter my mining a bit maybe go to direct mining of a few coins with all my   gpus'

and maybe  mine with new address for my  asic's

this is why I built a new wallet and rebuilt an old one  I now can send coins to them.

i also sold more btc.

How will the possible Bitcoin UASF, BIP148, BIP149 and SegWit2x affect you
2017-06-19

Dear users,

As you probably noticed, there is a lot of discussion around Bitcoin UASF, BIP148, BIP149 and SegWit2x among the Bitcoin developers, investors, companies and other interested parties. Since we're receiving several questions regarding how will our service respond to these proposals and how will affect you as a NiceHash user we prepared some answers.

NiceHash stance

Fist of all please note that our NiceHash hashing power marketplace is open for mining on any third-party pools that hashing power buyers are using on their hashing power orders. That said - we're not running our own coin pools or coin wallets and therefore can not directly affect on any blockchain voting mechanism.

Secondly, we're using BitGo's Enterprise hot and cold wallets to store your Bitcoins on NiceHash account. That said - your Bitcoins will stay safe on the "strong" chain in an unlikely Bitcoin chain split. BitGo is supporting hundreds of top Bitcoin Blockchain companies (besides NiceHash) like Bitstamp, BitBay, Kraken, etc. Any decision that BitGo as our wallet provider will take it will therefore be carefully evaluated among several interested involved parties.

Moreover, it is also important to say that we strongly support good solutions that will increase Bitcoin Block size, consequently increase Bitcoin transacting throughput and consequently lower the transactions fees. We believe that SegWit is a good option, therefore we support it and we also already enabled and signalized SegWit on our Solo pool. Hopefully SegWit will be soon enabled on Bitcoin - it will benefit us all.

We would also like to stress out that the Bitcoin ecosystem including developers, stake holders, investors, miners and others is built on sane common goals: to make usable and valuable crypto currency. It is therefore highly unlikely that any of the new proposals or changes will be enforced dramatically. It is also highly unlikely that the changes would be enforced in such a way that Bitcoin's value would be significantly impacted since this would benefit none.

Here are also some quick summaries of UASF, BIP148, BIP149 and SegWit2x

"User Activated Soft Fork", or "UASF".

The basic idea of UASF is to release a Bitcoin wallet client (like Bitcoin Core) that at a specific date, in case the safe threshold of the original SegWit is not activated yet by miners, starts to enforce the new rules of the soft fork, disregarding the signaling failure. The reasoning is something like this: if many users with economic relevance will start to use this client, but the majority of the hashing power will refuse to cooperate with them, the coin will temporarily split, taking most of the economical value on the SegWit fork. Many miners, at that point, will start to comply, in order to mine coins that are actually worth something, assuming that their contention was just a contingent political move and not a real, fundamental, economical or technical concern. In short - with UASF those who are Bitcoin users are deciding over SegWit instead of Bitcoin miners.

"Bitcoin Improvement Proposal 148", or "BIP148"

BIP148 is implementing UASF by proposing the following: nodes running this version would start to reject blocks that are not signalling SegWit (as well as signalling blocks built on non-signalling ones) already on August 1st 2017, way before the current deployment's expiration date (that’s by necessity, because the proposal actually leverages the current deployment), and they would outright reject any chain built on blocks that don’t signal readiness themselves. BIP148 could appear as a rushed and "aggressive" proposal, associated with a significant probability of reluctant miners splitting the network, at least temporarily. Even if the split eventually resolved, it would do so creating a huge and painful reorganization on the non-BIP148 chain. Bitcoin Core, traditionally used to follow established policies of slow, safe, smooth and minimal change, is not likely going to merge this proposal (even if many developers of the group support it).

"Bitcoin Improvement Proposal 149", or "BIP149"

BIP149 is implementing UASF by proposing to initiate a second activation process, in an orderly fashion, only once the current activation attempt will time out unsuccessfully, in November 2017. This second activation process would differ in that, after the signalling process, SegWit enforcement would be autonomously activated by nodes running this client, even without reaching particular thresholds. This enforcement, anyway, would not include rejection of any chain built on blocks that don’t signal readiness for SegWit after that flag date: the new rules would be enforced only on blocks that contain SegWit data, allowing “non-signaling” blocks to be mixed into the chain. Thus, miners that don’t change anything would build on the SegWit chain, without serious disruption. In order to cause the network to split, a majority of adversarial miners would need to deliberately and continuously reject every SegWit block, or to mine blocks with invalid SegWit transactions, valid for legacy nodes but not for updated nodes.

SegWit2x

SegWit2x is a kind of "accelerated" version of original SegWit, but in contrast to original SegWit it also implies a hard fork. It relies on 80% of miners saying they are ready and support it. Here another signalling bit is used (Bit 4) first before the actual SegWit BIP 9 bit. The SegWit2x code run by miners sets out that once 80% of blocks that they mine are signalling using bit 4 they (the 80+%) will then orphan any blocks that don't signal SegWit under the BIP 9 rule. The final result is that 100% of blocks they mine are then signalling SegWit and BIP 9's 95% activation threshold is triggered. Because this activates SegWit under BIP 9 all existing SegWit ready nodes then get SegWit. If Segwit is activated on the main chain then all existing SegWit ready nodes will see that SegWit has been enabled - not just the nodes running SegWit2x.

Final words

Hopefully these brief explanations gave you some more insights into the current development around Bitcoin soft and hard forks. Once again, please note that the Bitcoin ecosystem including developers, stake holders, investors, miners and others is built on sane common goals: to make usable and valuable crypto currency. It is therefore highly unlikely that any of the new proposals or changes will be enforced dramatically. It is also highly unlikely that the changes would be enforced in such a way that Bitcoin's value would be significantly impacted since this would benefit none.

Thank you for using our service and stay strong with Bitcoin!

Best regards,
NiceHash team.

Very good info, you are right I had around 40 nanos dual mining dc all of last year and only 20 of them are still alive, on the RX cards I have only fried a few so i dual  mine with the higer end 480s
but you are right i can tell the cards are dying slowing due to the summer heat.

My question is why do you care if they die ? I just RMA them since they are only 1 or two years old ?

on 3) yeah you are right Nvidia is way better on ZEC but I have found dual mining with 1070s and 1080tis is basically close to a wash in profitablity since the 1000 series does not really use much more power dual mining
compared to the RX cards ?

That being said my 20 remaining nanos are stil dual mining SIA and Eth, mostly because I cant downgrade my drivers to mine ZEC , I have 20 i need to RMA though I keep putting it off.

Just doing some catchup on my reading, since a number of us here at Phil's thread use Nicehash... pls read

@Marvell1

After running ETH farm for nearly 2 years now.... I learnt an important lesson, esp if you have 20-30 rigs farm.

Rule No 1 -- always under clock, and under-volt (modded ROMs for low power higher hash if necessary)
Your gear will last longer this way.
Substantial savings on power bill too.
You can manage the cooling solution better.

Rule No 2 -- never dual mine otherwise hell will break loose sooner or later.
Sure you get a few more bucks for the 2nd coin.... but the RX isn't really optimized for the 2nd coin in Claymore's list.
When the profitability is better, I usually get my non-RX rigs, like Nanos and 390s, to mine DCR, ZEC and others directly

Rule No 3 -- always use the best card for the best coin type.
While all my AMDs are ETH mining.... all my 1080tis are mining exclusively ZEC, because simply NVIDIA cards are very good for ZEC

Impressive build 12 GPU one rig who would have imagined, you try to dual mine with claymore on a bigger PSU maybe ?

Yes I want to do that to begging with.

I have a KFA2 GTX 1060 6G (85W mining Eth at 24MH/s right now)
psu 750W Gold+(enough to have a second GPU, got an old GTX 660 ti 2G, i'm considering plugging it as a second GPU to mine with it, don't know what it can mine exactly)
mobo is an MSI Z77A G45 ( https://www.google.be/search?q=msi+z77a-g45+gaming&source=lnms&tbm=isch&sa=X&ved=0ahUKEwji0p_B_4TVAhVBLVAKHXZ5DlQQ_AUICigB&biw=1920&bih=1012#imgrc=Hl5WOGKaeFVTqM: )

xhat can i do with that?

I was also considering building a rig, investing in this market, right now i could get a rig of 8GPU 1060 6G for about 3K$, which seems ok. Still hesistating considering the actual downsing on the big coins.
The goal in that would be to first, pay the rig with what i mine, then, mine to hold and make a few buck here and there, start to trade coins, etc...

All 12 x GPUs working now -- one riser was not snapped in properly.

According to Cryptomined's video, 16GB is recommended but that was for Windows.

He tried 8GB on windows and no difference.

So since I am using Linux, I used 8gb (4gb x 2) -- this board only have 2 x RAM slots.

The CPU is a small Celeron G3930 as recommended by Cryptomined.

This rig is on smOS Linux. Next few days, will try it on 1070s on nvOC Linux. Cant wait to see that running on my small NVIDIA farm.

Biggest challenge for this mobo I think is the PSU size that you would need to get things together stable without maxing PSUs.

I get about 1650-1880watts, and just under 8Amps to run this 12-card rig. I use a Delta 2400w server PSU kit.

Space, footprint savings is clear. But you save on CPU, RAM etc too. Perfect for my modest ETH and ZEC farms.

And lastly that sub-10ms share submit times.... that's the Dwarfpool node closest to me.... I suspect the hosting ISP is just next to my warehouse....  

how are yo ugetting such low ms on accepted ? normaly I only see around 20-60 ms

I have two rigs (the first two I've ever built myself) both with the capacity to run 6 gpus, but when I try and add a 5th gpu the miners just don't work.

Both rigs have asus z270-a prime motherboards.

1 has 1200w psi the other has 1300w psu

I am mining ethereum on windows 10 using Claymore.

All the gpus are connected using risers, and all the risers work individually

The first rig runs 4 EVGA geforce gtx 1070s. I tried adding a 5th of the exact same card and it did not work. Also tried adding different gpus and they did not work. When a fifth card is added the system seems to boot properly but then only 3 cards are recognized, both in the device drivers and in claymore.

The second has various cards. There are 3 1070s and 2 AMD 580s. It will run any combination of 4 of these cards but I get a black screen on startup and then it eventually turns off.

Ive looked into this issue a lot but can't seem to find a way to fix it. I've heard there are issues with adding a sixth card sometimes but I can't even get a fifth.

Any help would be greatly appreciated!

Selling 4 'reference' RX480s, if the price is right.

https://bitcointalksearch.org/topic/wts-4-x-amd-rx480-reference-video-cards-us-only-2015142

Selling?   Im selling hardware and BTCright now because I have medical and other expenses that are drowning me..... that's the prime reason.

I have been heavily investing in alts;  but not in the usual way this last month.

My trading account has fluctuated in the last 2 weeks by as much as 33% mainly on the larger more traded coins;  but;  it always bounces right back up to where it was when all this mess started.... which is just around the highest its ever been.    My experiments most recently with buying "offline" coins on yobit for the shakeup has definitely be successful.  They seem to be BTC resistant and more resistant to market flux.  In all reality, its more profitable because people are apt to dump theirs at bottom satoshi when they feel the need to move funds around.   NKA on yobit being a prime example.   0.00000003-0.00000006 trading for weeks in that coin.  Superb profit.  Granted; a lot of them are still @1, but that's not a loss;  and almost all that I buy so cheap, have an active buying market, so I technically only risk a touch above 0.004% loss (on yobit via tx/order fee) if I have to sell back at bottom satoshi

For all the BTC I am still holding when the fork comes about;  all of it will be on my ledger, aside from what I keep on the exchange tied up in buy/sell orders.  I want ot be prepared for the market to swing in either direction.      The market is the risk originally;  so I understand my reasoning and actions.

My hardware;   I am just cleaning out the Maxwell gear and making room for Pascal cards.  I typically host cards for people I personally know at a % split.  Eventually, Ill end up buying the card(s) from them and they have been more than happy with the profits in the end... and Ill run them until I need room, and then craigslist them.

I consider myself to not be poor, contrary to what people around me think.   I don't have a bankroll, and I honestly barely get on day by day sometimes.    Tis the life I was given, and I make the best of it.   No matter how the market goes;  Ill still be in it.  No matter how the mining scene goes, Ill still be in it.

I just stay focused on both sides of the line... past present and future tenses.
