Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)

[avirdoz]

So atm no working solution for windows 7 with Claymore 10 and blockchain drivers? I've read someone has successfully run with such setup.

"First" unnoficial drivers, works fine.

4 RX VEGA 56 + 1 RX VEGA 64
I used my VEGA 64 BIOS to flash on VEGA 56.
It works great ... I'll try to tune it more after some tests

Full rig 850W at wall

Hey, just seen your screenshot.
What was the  performance on the 56ers before flashing 64BIOS?

I am using 2x 56ers, but I am having trouble in AMD Wattman to set the voltage and both core + mem clocks.
Whatever I set and applay, it would just not utilize the specified values.
Also, in my settings, cards will crash at around 950 MHz.

Cheers

You mean robinhood driver? Didn't work for me ((

Hi!

I've experienced a weird bug on my new rig (6 * vega 56) . Everything works fine when I use 5 cards, but when I add the last one it boots, but 1 gpu always fails at the start of the mining and it freezes in seconds.
I've tried all the cards before one by one and they are perfect. Risers are fine as well. The weird thing is that when I try to start mining only 1 card fails, and it's not the same, it seems its a random stuff which one fails.

Config: Asrock h81 btc r2.0, g1840, 4gb 1600Mhz CSX, 2*750W EVGA GQ, WIN 10 64 pro, [Suspicious link removed]pute driver 2017-08-23, PSU1--> system, 3 cards and their risers, PSU2--> 3 cards and their riser.

I've tried to run 3 cards and the system on only 1 PSU (for days) and it worked perfectly --> ~620 W from wall. PSU shouldn't be the bottleneck.
I've tried to reinstall driver. I've tried to lower the power targets of all card by maximum 50%. I've tried stock settings. I've tried stock settings with 100% fan speed.
As i mentioned only 1 card fails per each start, but it looks random, it's not even connected to the same PSU.

5 cards work perfectly, 39Mh/s/card in solo mine, consuming 1010W from the wall.
Is it a software or hardware bug? I can't even guess, and I'm out of ideas what to try.

Any ideas?

Thank you!

I've had this problem. had to use DDU and remove the drivers completely and go back to square one. Once drivers were removed placed one card in the machine and installed the driver, shut down and install the rest of the cards.

Thank you! I'm gonna try this!
I've tried to reinstall driver using DDU, but all the cards were connected.

Did you have the same problem? Have you tried to simple reinstall with cards in and it didnt work?
After driver install on 1 card you put your cards at the same start or 1 card plus, restart 1 card plus .... ?

Its workiiiing! Thank you very much. I had no chance to figure it out by myself!

Hi! Someone could post the Power Limit value on MSI Afterburner for a 6x Shappire Radeon RX 480 (Samsung memories, 8GB version) rig? I don't know how affects this value on GPU performance. For now I keep it in "0" with -96mV and automatic fans control. Many thanks in advance

Re: 40Mh/s swing for dual Eth&LBC dual mining

https://ibb.co/dH1UR5

I am getting reported hashrate as high as 161Mh/s and as low as 120Mh/s when dual mining eth & lbc. Is this normal? Many thanks in advanced.

Decrease your "-dcri" intensity for more stable dual mining. For me it works like a charm, in Decred I decrease "-dcri" intensity from 25 to 21 and my global hashrate increase on ETH from ~173.5 to some incredibly stables 175MH/s.

I got my dummy plug yesterday and started overclocking. While at it, I installed the blockchain driver, instead of previously installed 17.7.1.

Is it normal that fans run very loud now (even at stock clock speeds), while they were reasonably silent before?

Another thing - one of the cards doesn't want to be overclocked. They are 3x RX 570 + 1x RX460

-mclock 2000,2000,2000,0 -cclock 1120,1120,1120,0

The first card shows no increase in hashrate, second and third go to 28MH, and for the RX460, I have yet to find good clock values. Any sugestions?

[LGMS]

Is there a way to set the fan speed on one fan, but leave the others running automatically?
-tt -50
sets all fans to 50%
I only want to set the first one to a static figure. The rest i want to be automatic as there originally were?

Have you tried -tt -50, or -tt -50,,,, (it depends of how many cards you have and which position is your card you want at 50%)

It works for me with 2 cards

Check if the first card is in crossfire
What do you have for memory on your 570's you should be able to go 2050 mclock and 1175 cclock on those if your dual mining else you don't need cclock higher then 1050.
Also for the 570's set cvddc 900  and mvddc 925 I have 3 570's with hynix and they are doing 29.3 and 66 LBR with 115w as reported by GPUz (I know it is higher then this by a about 30%)
if you are mining LBR set Drc to 20 if you are mining Decred set it to 25-30

Trying to dual mine eth+sia with a few RX 580 I have here and the numbers are quite disappointing.

Is there a way to OC them without flashing a new firmware ? (Sapphire Nitro)

I raised the memory clock with AB but it doesnt make any difference.

Had two questions. One regarding Asus Strix Cards and one about dual mining.

My rig is 4 Gigabyte RX480's, 2 Asus Strix RX480's, Windows 10, Blockchain Drivers, MSI Afterburner, Uber mix 3.1 Timing Straps, Samsung memory on all cards.

My 1st Strix card has the following settings. 0 , 50% power boost, 1190 CPU, 2015 GPU. Runs at 29.6 Mhs. If I put the GPU speed up any higher it starts at a higher speed, but slowly loses hashrate. Not a huge deal to leave it at 2015, but wondering if anyone has seen this behavior.

My other Strix card is the bastard child. (The original card was RMA'd to Asus and they replaced it with this one) All of my other cards run 100% stable for days. But this one card is just not stable at all. Here are the current settings. 0, 0, 1250 CPU, 1975 GPU. I've tried underclocking this thing on just about every setting. It may run for a day, 3 days, 1 hour, Open CL fail on start up. But lately it has been going less than 6 hours on average and I am having to restart my rig multiple times a day.

It just baffles me that something can run solid for 3 days straight, then not load on start up, then run for 2 days, then have to be restarted 5 times and then run for an hour.

My only other thought is to flash the Bios to Uber mix 3.2 which is a little slower and see if that helps. Any other thoughts or does anyone have some experience with these cards?

2nd question. This is about the dual mining fee. My understanding is that the 2% fee while dual mining is for both Eth and Decred in my situation. That would mean that I am getting 98% of my Eth and 98% of my Decred profits. If that is the case it does not really seem worthwhile to lose an extra 1% of Eth profits to dual mine. Please don't think I am complaining about the fee. Claymore program is fabulous and he can charge whatever he wants. Just want to make sure that it makes sense financially. I'm almost 100 sure that Sia, Pasc and Lbry are not profitable to dual mine right now. Decred seems the most profitable. Just wondering what you guys are all doing? Worth it to dual mine right now?

Man, you are so usefull around here:)
If I understand "crossfire" right, it is when two or more applications claim control over the card. It must have been the case here, because I had to manually rise the memory clock in Wattman, and the card started showing ~28Mh. Do you know how to repair this? - How to tell wattman to release control:P

Two of my rx570's have Elpida, and one has Hynx ram. I only mine ETH so far and don't plan to go dual until I feel I know what I'm doing.

Probably need to change -dcri (+ and - changes on the fly).  Should get ~600MH sia with no loss to ETH speed.  I run 1100 core because extra core doesn't benefit enough for extra power.
With Hynix mem, OC above 1750MHz slows mining due to memory timings.  Flashing is pretty easy, just need to run pixel clock patcher to disable bios check.

Crossfire is when the AMD Drivers tell 2 or more AMD cards to work as one card. The option should be in Wattman under the second card. Go to Gaming in Wattman and under one of the 570 cards you should find a setting Crossfire, check to see it is enabled if it is disable it.

I use Google Remote Desktop. Not full of features. But you can view your rigs screen, adjust settings and restart it.

Guys sorry for the newbie question but when trying to mine ETH and Dcr what address do I use for nicehash? My bitcoin address or the wallet they provide on website?

From instructions both addresses are the same but I don't know if that is nicehash or bitcoin...
nicehash Ethereum+Decred:
EthDcrMiner64.exe -epool stratum+tcp://daggerhashimoto.eu.nicehash.com:3353 -ewal 1LmMNkiEvjapn5PRY8A9wypcWJveRrRGWr -epsw x -esm 3 -allpools 1 -estale 0 -dpool stratum+tcp://decred.eu.nicehash.com:3354 -dwal 1LmMNkiEvjapn5PRY8A9wypcWJveRrRGWr


If it is bitcoin how does the payout work? Same as pools that it will give payout at certain threshold?

EDIT: Ok so figured out it was bitcoin address by typing it in to the find miner in NiceHash... Noticed from Claymores address that large source of income on Nicehash comes from Cryptonight... How does that work? Alternative software?

Does anyone know if there is a way to find out which of your GPUs had its shares rejected?

I see things in the logs like "07:37:41:022   1d8   ETH: Share rejected (250 ms)!" but it doesn't say which GPU that was for whereas when you find a share you know which GPU it was "07:37:40:772   1d8   ETH: 09/16/17-07:37:40 - SHARE FOUND - (GPU 1)".

I would like this information to identify which of my GPU is causing my rejects to see if I can do something about it.

Thanks
