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

[RAKOT]

Dear Friends, I need your help.

I have 2 rigs (3 cards + 6 cards) RX 570-580. Before Claymore v15.0 (up to November), it used to work quite stable... I had 75 + 155 MHs.
After the update, it basically stopped working at all... Drivers seem to fall leaving me with 1-2 cards running at 10mhs and consuming 140W (according to afterburner).  I'm using Aug. blockchain drivers.

So... I tried everything I could to make it work... I literally ran out of ideas.  
- I tried different configurations, reducing mc and cc, changing power limits, voltage, etc. kind of tradeoff efficiency for stability.
- I tried to auto-restart the miner (and computer) and run via .exe and bat file. (I even tried restarting pc every 20min or so).
- different drivers didn't work as well...
- I tried changing RAM to 4, 8, 16 GB...
- configuring autoburner so I have ±100 W; stable. (gives around 22mhs per card, which is not much... and still, it crushes.

I set up everything... eave the rig... it works 15 hours in the best case scenario... (usually 2-3 hours) and then ... drivers fall leaving 2 cards 10mhs. then I reinstall drivers, config auto burner and everything repeats. I think I was able to detect the error once before the crash, the red line said: "OpenCL error, -36, cannot write buffer for DAG". I'm not sure if it's related to what happens but this what I was able to see.

At this time it's more like a hobby than earning. I call it 'my little tech club' - I'm trying to make it work because I enjoy when it works stable... I'm not a tech or hardware guy and I learned a lot through the course of these years. But past experience was very disappointing. The rig is not in my house and I can visit it once a week in the best,  I probably spend more money on gas (not counting my time).  

Please give me some ideas about what can I do to make it work stable... maybe with fewer MHS, but stable. I would appreciate any advice on how can I make it work.

Thanks, dear community!

Well, basicaly in that situatuon best practice is to disassamble the rig and start building from the beginning . Starting from 1 GPU on rig board. Geeting stability on 1 GPU then adding one by one.
ofcz if you are distant is looks not so convinient , but its most efficient way.  IMHO

Anyone still mining with RX480?
Still worthed? What are best settings and estimated speed to obtain please?

Hi everyone,

I'm getting this error message since a few weeks:

Code:

Pool sent wrong data, cannot set epoch, disconnect

I've searched the web for a solution for this issue, they all say to update claymore, but since
I'm using v15.0 already this doesn't help. I've tried older versions aswell: same thing
One source mentioned to change the esm value, but that didn't help either.

Any ideas on how to fix this?

Systeminfo: Windows 10, RX580s

Just wanted to fire up some mining since it's actually an option again (long story) but i get same error

actually same for cc old miner, new miner, ella, rvn, etc,

I was running 6 months ago and believe a power shut down let an update into windows or something. Of course i forget all this till open pc, download latest version first

hi, what is the best miner for 1080 TI's for ETH right now, is it again Phoenix, and what are your ideal memory strap settings ?..

Also is ETHlargement pill uniformly recommended for all setups to improve performance ?.. I had switched to mining other coins for a while, so I would appreciate the latest cutting edge configurations specifically for 1080 ti's ...

Thanks in advance

Dear Claymore,
1. Do you plan to do something with the problem when AMD cards with 8GB cannot load the 379th dag file?
2. Do you plan to do something with the problem when amd cards with 4gb gets 0 mega-cache from 350 to 378 dag files?

Do you have any developments on these issues?

It is funny with 4Gb video card in windows 7 I can mine, but when I install windows 10 on the same computer I can not mine anymore because I get error
CUDA error - cannot allocate big buffer for DAG.

anyone knows why is that happend?
Can I disable something in windows 10?

Increase the virtual memory.

W10 use for the OS 600mb of GPU memory cannot be solved, it is a ''feature'' of windows 10

This does sound like a virtual memory problem.

It's a simple enough procedure, but if you need help configuring your VM in Windows, I recently updated my guide here: https://www.cryptoyeti.com/cannot-write-buffer-for-dag-error/

All GTX 1070 cards after changing the Eth era to 315 began to issue 23 MH instead of 32 MN, another miner gave out 31 MH. What is the reason?

Its not a virtual memory problem. Windows 10 has some system resources or cache that it uploads to the GDDR whenever windows starts and along with the large DAG, it exceeds the physical memory requirements on the GPU, its not the virtual memory.

There are 3 solutions to this

1) Put a 8GB video card in the main PCIe slot of the motherboard, its usually the one that is PCIe 3.0 x16, usually label PCIe slot 0. You can put the 4GB in the other slot and it should work.

2) Use Windows 7, however there is a max of 4 GPUs limit and no more security updates.

3) Use Linux. There is some learning curve to this. My biggest issue was correctly installing the display drivers.

Exactly, i have the same problem ... nothing helped, changing virtual memory, power limit, clocks, bios straps...

PX 570, PX580, GTX 1660ti do not lose MH.

Hi, is someone using linux as os to mine?
When i do OC my gpu mem i get less hasrate, at default settings i get 22 and if i oc vram i get 18 19

 :oIs Claymore dead? No further development? 
why no UPDATES ? Claymore miner dev

dwarfpool is dead after 16 feb. but fee to dwarf. wait new version?

UPDATE! ETH pool is closing. Please switch to another pool by 23th February, 12:00 UTC. All balances will be paid out automatically.

Not sure what you mean. I have a rig with nothing but 1070 Founders Editions (8 of them) and I'm looking at a minimum of 252MH/s. That's an average of 31.5MH/s each.
My clocks are:
Memory: +675
Core +150
Core 925mv
PL 100%
Fan speed 75%
Temp limit 80C

Temperatures range from 63C to 74C

Nvidia drivers 441.66
Windows 10 Pro with 16gb on onboard memory and 56gb of virtual ram.

I am using PhoenixMiner 4.9c though. Not sure if that's making any difference.

it is the hash that falls on Claymore, switched to the miner Ethnminer hash 31MH
