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

[aizzaku]

Hey!
Just built 2 rigs (both with very same hardware).
When I run dual on rig1 it works fine, on rig2 insta crash and the computer reboots (this issue only when dual mining, when mining just ETH works OK).
Any idea?

did you try dcri settings mate? maybe start from lower values and increase with + and see the stability.

Hi Claymore,

I've received a few reports from users running Awesome Miner to monitor Claymore Ethereum miner about issues with larger number of GPU's. In some systems when you have a large number of GPU's, you get a timeout on the Claymore monitoring API - it simply doesn't respond within a reasonable time. If the user is starting the mining process with a few GPU's less, then it works fine again. So when you go above a certain number of GPUs, the monitoring API isn't working even if the mining itself is running fine.

Is this a know issue? Are there any workarounds?

Thanks!

Please send me some logs so I can check the reason.

Ok I see big delays now. What CPU do you have? What average CPU load in Task Manager?

No more PM, so I write here, after sending logs,
CPU model: Celeron G3930
CPU LOAD: 53%-56% normaly taken by EthDcrMiner64.exe, everything else is up to  5%
MB: ASRock H110 Pro BTC+
RAM: 4gb ddr4

no change with new version ( with high priority ), I tryed and with other CPU act the same way when 12 cards

What CPU did you try?
Try to specify "-tt 0" option to disable temperature control, does it help?

CPU Pentium G4400
-tt 0   did not change anything

Whats about memory ? You only got 4 GB of RAM ?
Little less ?

Little less ?

4 gb ram and 33 GB swap

tryed 8 gb ram, this just used little less swap, no difference  on the problem

Guys,

Sorry to bring the bad news, but dual miner might be over in a few months.

Asic miners on the market are now spiking up the difficulty for LBC/DCR/PASC/SIA

Dual mining maybe gone soon as GPUs cant compete with ASICs, you have have noticed rewards and payouts and difficulty and spike lately, Devs of claymore may need to reduce their fees. to help in a few months.

ETH asic also announced, release in coming weeks.

Do you even know the basics of ethash algorithm? it is so memory-intensive that it would be too hard to design an ASIC with that much memory, let alone a compact size (like the S9).This fact makes eth ASIC-proof.

Try again next time.

it only takes 4gb to mine... PoS is coming late 2018
its coming, start selling ur rigs.

It only takes 4GB system RAM, and about 2.5GB on each card (increases over time). That is not the point. Ethereum mining is extremely memory intensive, making memory bandwidth and latency the only limiting factor. If you made an ASIC 1000 times faster than a GPU... It would mine identical to a GPU given the same memory. High speed memory interfaces are not cheap. At best you may get a 3x improvement, not worth the investment cost. BTC ASICs are about 3000x faster than GPU, LTC about 150X, others somewhere in between.

Why? Just switch to another coin...plenty of them out threre.

Ethereum has the overwhelming majority of hashpower pointed at it due to its market dominance. So, everyone will need to switch, lowering profit across the board. It will still be profitable, but reduced a lot, depends also on the coin market. Not necessarily bad enough to sell your rigs, but we shall see.

Just upgraded to version 10.5.. anyone notice ETH hashrate drops with GTX 1060 cards? I was a fool and decided to upgrade three things at once and now i'm trying to figure out what caused the drop down to 15 mh/s.

1) Claymore 10.5
2) Driver 390.65
3) Windows 10 Build 17074

what i have noticed is that before you update your video driver, you need to use some cleaner to wipe everything. for my amd it was happening. as soon as i did a clean install, without anything the hashrates were back up.
i am not sure if that works for nvidia.

I did a clean install and no change.  I think its Win10 17074 but just wanting others to confirm there are no issues with 10.5 or the latest NVIDIA drivers.

i just updated from 10.2 to 10.5, no change in hasterate on my rig.

lets see if someone has issue on that win10 update.

Just do a roll back on the Windows update or strip off and reinstall your drivers and it should be fine.  The forced Windows updates are highly disruptive to the miners.  V 10.5 has not affected my machines at all.  But the forced Windows updates (had disabled selected on all machines and it still forced itself on all of them) have tanked each of my machines' drivers and its as simple as running DDU and reinstalling.

Any idea?

If it is crashing when the program goes into the DAG creation, use -lidag 2 to slow that process down so it doesn't hang and trip, I have had this issue on some rigs and this fixed it.

Today I’ve noticed on my 7 RX 580 Rig that the Remote Manager link disconnects every few minutes when mining. I just recently increased my mclock to 2175 from 2150 on all but 2 cards. ETHI is 16, DCRI is 18. Clock is 1150, cvddc & mvddc 925. I have XFX XXX 8GB cards. Could the mclock increase be causing this?

I'm restarting up my miner from a clean slate after moving and my USB pen died, as soon as I try and run the miner I get the error:

"amdgpu_device_initialize: DRM version is 2.50.0 but this driver is only compatible with 3.x.x. Segmentation fault (core dumped)"

I'm running an R9 390 in this rig to test, I've never had this problem before and the only reference I can find to it online is this lonely post:

Hey everyone i was hoping i can get some help here...

Running 6 580s, i just installed drivers:

Radeon Software Version: 18.1.1
Radeon Software Edition: Adrenalin

i have 2 issues...

1. Setting up compute mode only allows me to do so on 4 cards, the last 2 i select compute but it goes back to graphics.

2. After burner does not allow me to control anything, i dont care about fans or voltage, i would like to OC only.

[Vann]

Somtimes AMD settings will still show gaming mode even after you switch to compute. Once you reboot, it should show compute mode for the cards. If you want to use the compute drivers, Afterburner will not work with AMD Crimson 17.11.xx or 17.12.xx drivers and multiple cards. Either use the Claymore config file to apply the overclock and undervolt settings at runtime, or use OverdriveNtool to create overclocking profiles for your cards as explained on www.mining.help.

If you want to use Afterburner with multiple cards you need to use the AMD blockchain drivers and you are limited to 8 AMD cards.

ty u good sir.

Do u know how many cards i can add to a build, i hear i can now go past 9 cards..
My motherboard now has 8 cards AMD and 1 NVidia, running windows 10 64bit... If i add pci slots how many cards can windows handle now?

Im running an asus z270A

also my GPU0 runs low when i OC the other cards the same, how can i set the GPU0 lower and the rest higher? i have 6 AMD on this build is it....

-mclock 2125,2150,2150,2150,2150,2150,0

Hi Claymore!
Can you please add offset voltage option as like in afterburner or trixx? I have a few cards with a permanent clocks and voltages for the all 7 states in bios (those cards working stable only with that trick and no way else, I tried all). So with the only one permanent state I can't set the exact voltage, I can only set the offset via af or trixx. But I wanna use only your miner for setting cards, it will allow me to fully automate the rig. Is it possible? Thx!

[cryptoillusion1]

Very quick question,
Been setting up my Rig which so far is going pretty well

44 m/h on Vega 64
30.5 m/g on Saphire Pulse 4gb rx 580

Though when i dual mine, the Vega drops to ~43 but the RX 580 drops to 23 M/h

What i am seeking help with is in the dual miner, only using the Vega to do this.

I have tried di - 0 after the SIA pool, but it limits all mining to the single card.
I have tried running 2 x Instances, but i get the message the port is in use, which makes sense.

So could anyone help me in configuring claymore to dual mine on the Vega "di - 0" but still dual GPU eth.

Increase or decrease -dcri using + and - whilst running the .bat file
-dcri   Decred/Siacoin/Lbry/Pascal intensity, or Ethereum fine-tuning value in ETH-only ASM mode. Default value is 30, you can adjust this value to get the best Decred/Siacoin/Lbry mining speed without reducing Ethereum mining speed.
   You can also specify values for every card, for example "-dcri 30,100,50".
   You can change the intensity in runtime with "+" and "-" keys and check current statistics with "s" key.
   For example, by default (-dcri 30) 390 card shows 29MH/s for Ethereum and 440MH/s for Decred. Setting -dcri 70 causes 24MH/s for Ethereum and 850MH/s for Decred.

I have tried running 2 x Instances, but i get the message the port is in use, which makes sense.

Also, the reason you get port in use error is that there are two instances on the same port (which you figured out). Just a reminder if you fix that...

By default it using port 3333 but the value of "-mport" is "-3333". The negative makes it read only. Don't remove the negative unless you put a password on it.
