lesson...gotta find the next big thing...hope all of us can get a huge chunk of it for the next shit show hehe 

9th thread ... rig-porn 

My first rig was a 5 x 980ti called Brutus circa end-2015 - mining ETH at 150Mhs... ETH was like $2 bucks.

Eventually I went all in and made 5 of these rigs.... 750Mhs of ETH... powerful stuff back then.

Solo mining .... 10-12 coins per day.... sigh   

PSU-wise, I've had only one constant: the EVGA 850GQ are crap. I've had three fail on me. Well technically the third one is still working despite one of the socket being burnt. The G2's are supposedly a totally different ballgame when it comes to reliability apparently. I've only got one and it's been fine for the past year.

I've got an XFX and a Silverstone still chugging from the 2014 days.

for me, i have solved that modular problem from being burned with this..

- always use two lines per GPU instead of using both 8pin (8+8) from a single line.

- one sata or pata per riser

and make sure all connections are tight-standard in all electric related stuff..


if modular connection is ruined and if warranty is not an option, I solder a new connection...or if the board where it was soldered don't have a good soldering point due to burning...i trace the wire where that soldering point (board) is getting the 12v source and tap in the wire and solder it. normally the modular part is just a board which is getting it's volts and grounds form a bundle of wires behind that board.

EDIT:

I agree on expensive PSUs being crap but only up to the point where the manufacturer like corsair can inject a program to the PSU and make safety triggers like it turns off if a spike or the load is kinda heavy...in my case ax1500i is increasing sensitivity when it is going above 1000w..

that ax1500i really has miners in mind haha that prick PSU even wanted to be turned off and on by its switch...because when i traveled abroad i asked a person to just turn off the electric breaker and turn it on (that person is not a tech kinda guy)...and that PSU just stayed off like nothing happened and when i got home i switch that PSU off and on and then it resumed mining.....corsair ax1500i engineers fuck you...there you go 

Since we are talking about PSUs, for me the more expensive the PSU the higher the failure rate.

Most of the larger >1000 Watt PSU are all modular, and almost 25% of them have had a burnt +12V wire on the modular side of PSU, very difficult to fix properly.

My cheapest PSUs the Corsair CX750W the ones we all bought during our Litecoin days, never had any issues. No wires were burnt or fried PSUs.

i hope you guys diversified outside of crypto..

9th altcoin thread..show your mining garbage/trash hehe 

i forgot to mention i have a dead ax1500i, died in less than a year at ~1000w......evga is not very available here yet, tried to purchase that earlier this year but the supplier's terms is not that appealing(forgot the details)..still gonna try corsair warranty performance here, evga might be purchased overseas here but getting warranty might be an issue.

an old second hand thermaltake 1500w also died-going for the trash bin ...thought it was the board,my very old socket 775 board circa 2006-2007 hehe..still kicking..

server PSU are not also very available here, some I've seen here are not my type...I'll just stick with new desktop PSU's and test if they are good with warranties...seasonic is good enough with warranties here...i'll watch corsair this time.

I had 1 failed Corsair PSU - 1200w - forgot which model - and I have since returned back to EVGA-1600 for all my GPU needs.

The EVGA-1600w that I have been using since 2016 are still working until today --- all 18 of them.

They have gone thru extreme mining conditions and I have no regrets on these high-end EVGAs - worth every penny.

For the riserless rigs, I standardized on Delta-2400w Platinums - these server PSUs are truly workhorses and very reliable.

I can’t buy that, all the gpus i had that failed failed due to heat , yeah some bad fans but only the brands with notoriously shitty fans. : xfx and gigabyte.  a card can fail  a month after buying it or three days, two years

shutting them down doesn’t guarantee when you fire the back up in six months they will not die after a week lol.

even at a tiny loss as long as its less than $500 a month i personally will keep mining, people have hobies that cost as much.  plus this is winter , my cards ♥️ this weather low temps nice frosty garage lol.

if they die they day /shrug

I'm buying more of 92mm PWM fans with 4 wire if it worked..experimented with my 280x...the 4 wire fans functions like the stock fans (can be controlled with msi AF), if wired properly to the GPU board (GPU fans are 4 wire too)...

..will attempt modification to my zotac 1080ti for longevity, 2013 to 2016 i have 280x, 2018 to 2021 i'll have 1080 ti  

..will test and clean each my year 2013 GPU risers with my 280x GPUs. i think a handful have issues...i bought newer versions looked cool (2nd hand)

..corsair AX1500i is a piece of shit...it will not function as a single rail even if the software says so, the engineers even designed a sensitivity crap that if my internet connection had a hiccup, it triggers the protection even it is pulling just around 1000w....hx1200 is better-no issues, AX1500i might work with a server that is just pulling ~500w or less as a masternode (might be good, PSU fan not spinning due to low temp/power).

Well  some mine to core address and wallet  with no one knowing  who owns the wallet except the wallet owner.

I would argue for some an address like this one

https://explorer.bitcoininterest.io/address/iRysZBkNVQmehvc2J5nWRouVuT2JUcUK7s

would be worth more if it was only known by the owner.  Then if it were staked and known  by many others.

Is it really worth mining if you have 8 cent power however. You make a nickel a day per GPU but you risk burning out your GPUs or killing your fans. Once your fans go you will need to RMA them and pay for shipping or buy replacement fans on Aliexpress or eBay for like $20.

Hence it's better to just shut off the gear and wait until the $1/day/GPU days return, if ever.

GPU and S9 mining is still profitable here - but the profitability IS a lot worse, I was making more on perhaps 1/3d the hardware 2 years ago vs what I'm making now.
I DID have to shut down some of my older rigs (R9 290s are history, and I'd already shut down the smaller R9 series and HD-7xxx stuff months ago) due to them going underwater, and the D3 units are just a little underwater right now (but they work well as winter heat).

I have been switching out of "pure crypto" the last couple months as a workaround for the "crypto rate increase" due soon - a rate increase that hits small farms a LOT worse than big ones, and is therefore very STUPIDLY set up and does not address the "why we are doing this" AT ALL.

And was unilaterally created with NO consensus that it was a good choice.
Without Bitmain forcing it to be used to back their miners for quite a while, it would have never had ANY traction and would have dropped down to pennies (or perhaps single-digit dollars at best) within the first 6 months.

They hold little over a million (%5.7 of the supply);

well you at least roied on your gear most ppl did not even come close.  My gpus roied but ia have six s9s and a bunch of d3 and a3 way underwater all shut off since the summer.  Never buying another asic.

i have lowe power at .8 cents in the winter so ill mine a bit longer but youre right with the tax it comes to .10 cents maybe 11, so im mining at a slight loss

Even the cheap power in Canada (Labrador) is not as cheap as before with "mining tax" introduced soon and smaller hosting setups being squeezed out by the bigger boys -- mainly from China relocated to Labrador.

So unless you know someone who has free power or inherited a nuclear power plant, the economics of most GPU and ASICs based mining is not profitable anymore.

My 240xGPU AMD farm is also now shutdown but I still power up my 22 x 1080ti every now and then.... hope this Crypto Winter ends soon.

The only consolation for my group is that the gears are ROIed and thanks to the 2015/16 investments - we had a good run with ETH from $2 bucks and BTC from $600 bucks.... well it was fun while it lasted.

Horrendous. It's 2014 all over again. Trying to chase some stupid no-name coins that might or might not still keep your rigs above water somehow. I'm pretty much done with it, tbh. Unless I can get an extraordinary power deal I'm shutting down my rigs... Unless I am sitting in my attic and need heating (because otherwise I'm fekkin' freezing)!

My group started the farms in 2016 using S9 Batch 1s and Avalons 721s and have ROI them esp during the BTC 20k highs. The current gear today, like 55TH M10s are too far of a gap, leaving our miners not worth powering up, and even this miner is under water with depressed BTC price now.

This ABC vs SV war is too hard to chase so I decided to put the 250TH farm to -ck's solo pool --- one last chance to hit a block before they retire. I personally hit 2 solo blocks at -ck in my lifetime. 25 BTC per block that time.... how time flies.
