Fourth alt coin thread last three got oversized.

[EvilMonkey]

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.

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

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.

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

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.

[JaredKaragen]

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.

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.

[JustCauseBIH]

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.

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.

[kopija]

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.

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

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.

Question about troubleshooting a rig powering off.

My new 4x 1080ti rig is shutting down now and then it just reboots.

It seemed related to one of my cards so I clocked that back down to defaults.  All cards running at 67 TDP or near abouts.  Total WATT used is 672 on a 1000W plat PSU.

I thought it might be related to them drawing too much power which is why I set the TDP down.

Doesn't seem related to that though.  Was mining for 8 hours straight no issues then just reset.  It was resetting within 5 mins when I had that one card clocked at +200 core.  When it was in a two GPU rig it was running fine at +200, but it was not on a riser.

Any thoughts on what else might be causing it?

As for your charts

Equihash   4683.88 Sol/s   0.00 Sol/s (0.00%)   0.0089 BTC/day

https://new.nicehash.com/miner/16yLHLoeyuCLPMXkVpC3gyrRYvwRGwjKJr


I assume you did all tests your self

4683 sols =  0.0089 btc

1,000,000,000 sols = 1900 btc per gh

your charts do not show methodolgy .

my number above is simply made from looking at hashnest result.

but If I pull it up 1x every hour I will get different numbers.

In order to show correct numbers like you have in your chart.

you need to run an identical rig for every coin  for 7 days simultaneously .

then give 7 results for each coin. day one two three four five six seven.

this would be a shot at a fair sample.

did you do that?

if not your rigs  did the tester do it.

with the crazy flux patterns  using a rig and testing coins 1 at a time  for 30 days in a row simply is inaccurate.

as you see  I get 1900 btc for 1gh of zec.  you get 2990 for 1 gh of hash

and now  nicehash reads.

Equihash   3916.74 Sol/s   0.00 Sol/s (0.00%)   0.0076 BTC/day


so 76/89 = .85 x 1900 =  1615 btc a gh

4 x 1080tis on a 1000w is a bit of a stretch unless you clock down the cards.

Remember that Gold rated PSUs even at 1000w effectively will hit the efficiency limit at 80% or 800w

so.... if you have 4 x 1080ti at 200w..... plus risers another 40w each, and mobo, CPU, RAM at 100w .... thats well off the 800w Gold level and 1000w "peak" level

best practise is to have 20% buffer from your PSU rating so that PSU runs cool and not overstretched since this is a 24x7 mining intended PSU

But have not seen the dips in the 24hr earnings graph.

 I've never has ANY of my miners show "reported hashrate" above zero on zpool OR ethmine - never understood how that was supposed to work, and as it doesn't affect shares earned don't really care about it.

 Trying to run 4 cards with a TDP of AT LEAST 1000 watts on a 1000 watt PS is .... very iffy at best, even if you set the TDP down you're still going to see occasional spikes that are a lot higher.

 Also, not all "1000 watt" supplies are the same, though a plat-rated one SHOULD be at least fairly high quality.

I said I have the cards clocked down.  Who doesn't.  I have them all around 67 TPD so that is pretty low.  They are all at around 165W. for a total of 673 Watt back to the power point.  It is a plat PSU it says its max power is above 1000W.

So I have like a 300W+ buffer.  THough I would like to bump the TPD up a bit if it is not the power causing the issue.
