My second ZEC + XMR+ ETH thread builds info links thoughts and photos.

I have 4 pandas and 51 rigs on Eliovp's site.  It works well.  Mining monero right now on pandas getting 6.4/6.5K on his rom and roughly 950 or so watts.  My 51 x 6 cards rigs RX470's getting 4.52K on 640 Watts =)

These are Eliovp custom roms so not free but well worth it.

At this point   I have 1 rig on his os  and a license for 9 more rigs.

I am going to open a skype account to talk with him about getting the os licenses working.

I want to be able to run my rigs on his os or simple mining os  before I buy any roms.

Once I can run on:

 windows 7
 windows 10
smOS
evOS

I will feel safe enough to get a custom rom for all my msi rx 470's 4gb size.

I really wish I purchased uniform cards. I bought a mix of cards, and everything would be custom and different. I have 4 reference 480s, and whatever else was on sale, 17 total. Hard to justify so many different roms

[LoneRangir]

@LoneRangir  keep plugging away at it.

Tried Ubuntu 16 instead of CentOS 7.  Same thing.  Gets goofed up in the bootloader when 6 cards are present.  I'll have to see if there is a MB bois update.

LoneRangir... save the whitehair and just use smOS -- its customised Linux crypto mining on a usb stick

yeah  works well.

Yes, I've followed the other thread. I may give it a shot, but at this point, I'm leaning towards a hardware issue getting to six, rather than software. Since smOS is linux-based, I have little hope that it will see all six. I'd love to be wrong, though  

Centos is more difficult to setup vs Ubuntu.

I think in your case, it may be a riser issue... just gut feel.

Going to Linux will fast track troubleshooting (ie. faster to identify and isolate issues; IMHO), vs Windows which may need DDU, reinstall Crimson etc.... take another "couple of hours"

I recommend this link below - I managed to get 6 GPU and 7 GPU (with 3-1 PCI splitter) setup on it during my testing days with Ubuntu.

On smOS, it basically has simplified my mining operations and I get to study more Linux now than Windows. I have enough of W10 and its bloody updates. I still have Win7 however, for my day-to-day workstation, Teamviewer, other monitoring, etc. in warehouse. But its all Mac and virtualised Win7 and Ubuntu at home

I've not done an apples-to-apples comparison yet, but the power usage under Linux (and perhaps smOS?) seems to be much higher. Four of the five working cards are reference 480s with modified firmware (low energy), but their usage feels way too high. And there's not great way to tweak the voltage further under Linux.

I'll do an actual compare when I get more time

On smOS...
My RX480s are all with Heliox Low Energy Roms.
Mining XMR with a 6xRX480 rig does slightly over 800watts.
Mining ZEC... just over 1000watts
Mining ETH... just under 1200 watts.

If I recall during Windows.... its no better than this.

For smOS, the kernel used in that Linux version seems to be where the magic sauce lies, and faster performance and power consumption are much improved in the last kernel update by Tytanick.

Finally got all 6 cards running.  Had to use W7 & the registry hack.  Neither linux distro would recognize 6 cards.  Rig consists of 4 x 480s (Reference & low energy rom) and 2 x 470s (1700 strap) in an open air frame.  Hitting 171 MH/s on ETH and about 1010 watts.  Tweaked all core voltages to be 0.98v or so using WattTool.  Core speeds between 1075 and 1100 MHz, depending on the card.  1900 MHz memory on the 470s and 2100 on the 480s.

We'll see if it's still running in the morning

What is happening at nanopool xmr

The performance for has been shit for good 4 days now.

Thinking about moving my hash over to dwarf pool.

I have tried all known Cryotonight/XMR pool -- and there is indeed funky things happening even at Nanopool and Dwarfpool.

Converting XMR collected back to BTC doesn't tally with my estimates.

With BTC moving up strongly, we are losing serious BTC because we waste our hard earned GPUs to pools inefficiency, increased difficulty, and other funky stuff the way XMR pools does their "calculations" I couldn't explain.

I have been doing some comparisons and at this point - IMHO, we will earn more selling hash to Nicehash Cryptonight market.

If you are interested only in getting BTC back for XMR; gut feel after miner fees and pool fees, it will even out at Nicehash.
Bottom line is we get BTC upfront for every shares sold at Nicehash.

If you want to mine and keep XMR then Nicehash is not for you.

I havent got a Linux miner that works with Nicehash (stratum+tcp://cryptonight.usa.nicehash.com:3355) -- the sgminer-gm-v5.5.5-4 was suppose to fix the cryptonight issues but still high rejects happens.

In Windows, Claymore's and other miners are doing fine at Nicehash.

All my rigs are on Linux with smOS and thats a bummer -- but I am getting the Pandaminer on Windows again, to start selling hash to NH, and will monitor it from there.

Anyone currently selling cryptonight at Nicehash?

It locked up about 5 minutes after I left the house.  I can only conclude that 1000W on a 1200W PSU is too much, or either 6 cards is just cursed !

I removed one card and am now pulling ~850W.  We'll see how this goes...

[philipma1957]

All my four card biostar z170 just run. No issues.


But xmr is doing something crooked across all pools not sure what it is.

6 of my rigs are on Biostar Z170. No bloody risers. Like Phil's - it just runs.

Since setting it up -- rarely touched it because it doesn't give me any issues.

Now with smOS thumbdrives... it just sits at one corner mining its own business.

I gotto to get those cheap msatas, Phil bought for a song, to replace the thumbdrives soon.

Btw, anyone mining ETH still?

I am thinking of switching to ETH at form of low intensity mode.

Tying out -ttli switch to auto mine at low intensity once a target temps is reached.

Anyone has tried this before?

I'm ETH all the way.  For various reasons, I've never switched to any other alts.  I guess I'm not a profit chaser. To be fair, I do convert half my ETH earnings to BTC, though. I feel like BTC (gold) and ETH (silver) are worth holding long term, and that the various other alts are going to ebb and flow.  I am not into 'timing the market'.  Once ZEC crashed, and I could no longer tell when was the right time to switch,  I have been just mining what I understand.

This is in direct contradiction to my insistence on getting a 6 card rig up and running, while all my 4 card rigs "just work"  .... I'm pulling the plug on the 6 cards, me thinks....

I mine eth still
I stay nicehash mostly due to it's almost number 2-3 on most profitable on whattomine.com
Payments come on time and I think I'm only losing maybe 1-2$ a week doing nicehash
I like the direct pay in bitcoin
I've made money doing direct pay with the decreasing and increasing of btc price

yup, direct BTC with all the tx fees being charged here and there, ie. Poloniex tx. fees, conversion fee... etc. -- NH charges slightly higher tx fee but I think it will even out

BTC upfront from NH is pure PPS, paid up to 4 times a day (every 6 hours) and they take the risk by paying us first.

My group's X11 farm is going berserk now with miners renting +600% above PPS -- it has been a good week.

[HerbPean]

I still mine ETH.

My new 2.0 H81 Pro BTC board finally manage to gave me some stability with 5 cards.

It's a mix of 4 470 and 1 480.

The 480 is running at the same spec as the 470.

getting 182 MH.

I just regret to have sold my 15 coins @0.01125 and not right now

[ps_jb]

Same here - on ETH for last two month. Mining directly to Polo wallet and selling right after getting 1 ETH.

Unfortunately, Claymore's XMR miner does not work with my 6x RX 480 8Gb Nitro+. No idea why - but it does not.
ZEC is less profitable.

So decided to stick with ETH

I am running the pandaminer on eth  230mh  and another rig 90mh  total of 320mh

I am running 14000h on xmr

[Tmdz]

Ok so I just switched to nicehash for XMR.

Gateless-gate miner works great for this, but like with sgminer-gm you must tune setting to get it rocking.  I use same exact settings as in sgminer-gm.

under sgminer-gm I got 100% rejected shares, gateless-gate solved this.

I think nicehash for XMR will be the best solution, mining the coin directly gets screwy at times when pools suddenly struggle to find blocks.  I use 20% less watts mining monero than eth so this is more profitable for me than eth, also less stress on gpu.

is there a Gateless-Gate for Linux?

I have been trying to find a solution for XMR@NH under Linux -- but NH team and sgminer forum threads are not much help.

[Tmdz]

Yes just go https://github.com/zawawawa/gatelessgate grab the linux binary's and build it for your system.

[bittawm]

do another build phill
