I have 2 issues with Claymore 10.0 (Win10, blockchain drivers, 6card rigs running 570 and 470 cards)
1) After initial rig start (i.e. after powering or resetting the whole rig) Claymore 10.0 runs with lower hashrates (for example about 23-25Mhs with 470/570 cards). After stoping the miner and re-run .bat, I getting normal rates (i.e. miner has to be restarted and operates as expected only after 2nd run, never from the first)
2) Unpredictable hashrate drop during mining for some cards in rig (usually 1 or 2 of them). Rate drops and keeps at 23-25. The only solution I found is to restart Claymore.
Any comments guys?

Ok so I fixed my issue with the low hashrate. Problem I'm having now is after a few minutes claymore will crash the computer, in the sense that the screen goes black and the fans on the video cards go to max and I have to reboot the pc physically. I do notice before it crashes, the hashrate starts dropping, little by little until it puts the pc back into that crashed state. Any suggestions on how to fix this?
Claymore keeps charging his 1-3% but refuses to fix this bug that is constanly reducing our payouts and earning from mining its really frustrating, I constaly get
connections closed on some machines on claymore v10 and v9.8 and when that happens the miner either crashes or i see that stupid 8mhs hash rate issue I am sure all other AMD and RX users are familar with
I wish there was another working miner i could use , but Genoli seems to have been abandoned /sigh
This was added to Ethminer but no overclocking control and you have to use a separate watchdog script. There is a post on this forum somewhere about it but you'll have to dig it up yourself.

I dont need the overclocking control, I use MSI afterburner mostly thanks. I'll test the ethminer release on some of my rigs, do you have a link to a good monitor tool
similar to ethman ?
My cards are not even overlocked much IDK all the cards dying are like 1850 mem and 1100 core which is actually super low , never had a problem until the dag fix deal

You need to use a monitor or dummy plug in the primary VGA for the AMD driver to be able to read and set the fan speed and temperature.
Really? I dont have monitors plugged and the miner control temp and fan speed. Does it have to do with some driver version?

Hello. A noobie question here - Where can i find a list of Claymore supported gpus?
I have a bunch of Asus HD 4890 lying around im only interested in low difficulty/value coins but i cant seem to make Claymore work on my cards, so i figured, Claymore does not support all cards, any list out there? Or any alternatives?.

There is no list. The old card I know it support is the 5XXX series.
Thank you, maybe any alternatives? Or im stuck with cgminer and scrypt,sha algorithms? While having no way to mine Cryptonight or Monero style alt coins?
Why on earth would you want to mine with a "bunch of" entirely outdated cards that are terrible at mining? You will pay literally ten times the amount you mine in electricity alone. Not to mention the heat all those thermally inefficient cards will produce.
Here are 5 reasons to NOT do what you are considering doing:
(1) HD 4890s are terrible at mining
(2) HD 4890s are not power efficient (250 watts+ each at load -- about double what my 1070s pull)
(3) HD 4890s get really hot (over 80c at load is not uncommon AT ALL -- 20c higher than my 1070s)
(4) Electricity is expensive (12-14 cents a kWh)
(5) GPU mining ALREADY isn't very profitable right now, even with energy efficient rigs
Even just running 2 of those GPUs will cost you literally $1.75 a day in power. And that is JUST TO RUN THEM. It doesn't account for the remainder of the hardware power or cooling. If you ran 10 of them (I'm not sure how much a "bunch" is), it would cost you $8.75 a day or $262.50 a month just in electricity cost. 10 of those cards will probably mine less than $0.25 worth of crypto in a day -- if you can get them to mine anything at all.
You will literally be losing money each day.
DON'T DO IT!
Well they arent any good i agree, they are really power hungry and old, but they were powerful in their days. I have 3 of them, i get kind of "free" electricity. my rent is "everything included" type. I guess im better off buying one good gpu.
Its just a hobby+ curiosity, i mean no one who were mining bitcoin back in 2010-2011 were profiting, i know it sounds silly but who knows maybe some no name coins will blow up and im interested mainly in them. Ill leave big coins for big guys, thats it, i dont look at all of this seriously, its just me trying and messing around a bit.
I know that you are 100% RIGHT that im better off to just buying those alt coins and saving lots of time and money.

Guys, i'm building a new rig - reason is my 8-gpu Gaming X rig got sold and I got some sweet profit 
I'm thinking to try Sapphire cards, but would like to have 8gb ones, if I could get a decent price. Here are my options:
8gb Nitro+ 570 - $350CAD
8gb Nitro+ 580 Ltd - $438CAD
8gb Nitro+ 580 SEL - $380CAD
4gb Nitro+ 580 Ltd - $363CAD
I know most would pick the SEL for $380 but it's out of stock right now. I could wait for a week or so but there's no guarantee that I could snag 8 of them.
If I ended up selling it again, then I won't mind getting the 4gb 580, but if I'm keeping them, I would like an 8GB ones for future-proofing.
What do you guys think? I'm wishing to get my rig built and up and running before Byz arrives on the 25th.

I think the best choice is the Nitro 570. This mining 29Mh/s on ETH or ETC. And look this MINING OS !! I would like to try it with my new cards

Can't say I'm familiar with that. My rigs run for weeks until I reboot them or unless they crashed because of something I screwed up, like having voltage too low/clocks too high, or not having the power cables connected properly, etc.

Whoever is still using r9 280x... I need your advice badly!
I have weird 13-26 mh/s ETH 29-58 mh/s LBC fluctuation.
Does not depend on overcloack, power limit, page file > 32gb different PSUs voltage, temperature or whatever, tried all the shit possible!

Nicehash users buying your hashes will sometimes mine a coin with smaller dag (like UBQ) and on that coin 280x will give you its full speed.
Thank you all!
I did setup separate zcash imning process for 280x-s & it seems like more profitable - getting 320+sols from each )

I see what you did there Smiley nice!
October 12, 2017, 07:12:54 PM
This is why you throw away those shitty SATA > Molex connectors and use the Molex cables that come with the PSU. It's not the wire gauge, it's the extra/crappy connectors. In open air you should be able to run 150W or more through the 12V wires even with 18 gauge. That should be enough to power 3 risers off of one Molex chain, and definitely safe for powering 2.
Alternatively there are newer risers that just take SATA. Haven't tried them but they'd probably work OK since, again, you don't need to use any janky adapters.
EDIT: Ok technical specs put it at 132W (11A * 12V) for 18 gauge...but still most cards shouldn't draw more than 45W through the slot (though technically they can draw up to 75W). Also there is some margin built into the ratings, so in open air with decent ambients and air flow, 3 cards per chain should be fine; and again, 2 is definitely OK (as long as you are not adding extra/faulty connection points into the circuit with crappy adapters, because that's where most of the resistance will be and can cause arcing).
https://en.wikipedia.org/wiki/Molex_connector#Disk_drive
That said, I remember reading about early 480 (and maybe 470?) cards drawing stupid amounts of power through the slot...so I would be careful with those.

I love learning all this stuff it’s giving me more knowledge 👍🏻👍🏻👍🏻👐🏼
It's giving me a headache ! Twiddle this up, tweak that down fiddle with this setting mangle that dangle and if you're lucky the risers won't oveheat and catch fire.
--ypsi
It's not the PSU extension that's the problem but the poor quality (low gauge) of wire used in the power cable that comes with the riser.
I've had a couple where the cables have melted the +12v line into the ground line but luckily did not short together, and one where it melted the molex connector (dodgy connect fault there I think - see pic).
I check all the cables and if any gets a little bit too hot I replace them with higher gauge wire.
I'm sure there are a few here who have had similar problems.

It`s like >2 times difference! And usually it is ~13...
In your case, Nicehash switches among different Ethash coins - Ethereum (DAG ~145 epoch), Ethereum Classic (~148 epoch), Ubiq (~8), Expanse (~23) and Musicoin (don't remember, about 15-30). AMD Tahiti GPUs are very sensible to DAG epoch, i.e. the DAG size in GB and with each epoch, the hashrate of Tahiti chips drops about 0.15 MH/s (estimate taken from forums).I have weird 13-26 mh/s ETH 29-58 mh/s LBC fluctuation.

AMD Polaris, RX4xx and RX5xx, did also exhibit hashrate drop connected to increasing DAG file, but the AMD Blockchain Workload beta driver fixed that issue. AMD will never release a similar software patch for AMD 7xxx, 2xx - these products are phased out.
I advise you to run a dedicated Claymore miner instance on these 280x, mining Ubiq, Expanse or Musicoin at a decent rate of 24-27 MH/s, rather than switching infinite times per day between ETC/ETH at 13 MH/s and UBQ/EXP/MUSIC at 27 MH/s.

In regards to allcoins, allpools, and the dag settings, what would be optimal for ETH and LBC on Nicehash?
I know ESM 3 is used, but it seems there is quite a delay when switching between dev fee and NH, pool side hash rate is usually 20% lower from it(or something).
