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

[Jonet]

I have a 12GPU rig with RX580-4's and am getting this:

Create GPU buffer for GPU2
GPU9, OpenCL error -4 - cannot write buffer for DAG

3 GPU's fail every time but it's not the same 3 each time. I can mine a coin with smaller DAG with all 12 GPU's enabled.
If I disable 3 GPU's with -di the rig is able to mine ETH

Any idea what I should do to get all 12 GPU's running with ETH?

can you send in the "code" your bat file config to see what is your setup please
it can be that you don't have this at the beginning of your config

GPU_FORCE_64BIT_PTR 0
GPU_MAX_HEAP_SIZE 100
GPU_USE_SYNC_OBJECTS 1
GPU_MAX_ALLOC_PERCENT 100
GPU_SINGLE_ALLOC_PERCENT 100

what Clay miner version are you using?

[Jonet]

This is what my start.bat looks like:

Code:

set GPU_FORCE_64BIT_PTR=0
set GPU_MAX_HEAP_SIZE=100
set GPU_USE_SYNC_OBJECTS=1
set GPU_MAX_ALLOC_PERCENT=100
set GPU_SINGLE_ALLOC_PERCENT=100


EthDcrMiner64.exe -epool eth-eu1.nanopool.org:9999 -ewal 0x*****************/rig021/***@***.com -epsw x -mode 1 -ftime 10 -cclock 1140 -mclock 2090,2090,2080,2080,2080,2060,2060,2060,2060,2060,2060,2050 -powlim 50 -cvddc 900 -di 012345678

Claymore v12 running on Win10 build 1809 AMD driver 19.4.1. The problem may have started when I moved from build 1709 to 1803 or 1809. Or it may be when the DAG grew above a certain size.

Virtual Memory Min 36000, Disable ULPS

Hi,

So I just started with all of this and am having some problems. Whatever I try (like changing virtual memory, got this now on 32000), I keep having these problems. I'm not in for downgrading back to Windows 7, sorry. Anyone who got any other suggestions how to fix this problem?

It gives me the following error: "cuda error cannot allocate big buffer for dag".

Thanks in advance!

Write :     -lidag 1   option in your command line.

Still doesn't work

I think I found the solution though. I saw this in the first post of this topic "9xx cards in Windows 10 x64: you have to use old drivers (for example, 352.xx) and miner built for cuda6.5.", I do have a higher driver atm, so downgrading should fix the problem. I'll keep ya updated.

I believe at this point your GPU needs a minimum of 4GB onboard to mine Eth.

....i cant control temp and fan speed trough claymore, any help?

You can use third party tools like msi afterburner.

When I check it there are three kinds of memory that it shows:
Approximate total memory; 10170MB
Displayed memory (VRAM); 2007MB
Shared memory; 8162MB

Thanks!

It has less than 4GB so that means I shouldn't be able to mine ethereum

[lisasteca]

Guys could you help , do you think mining  ethereum is still good?  what tutorial would you reccomand for people who start mining ethereum?

Just try look at Mininghelp with google

Thanks for the adivice , i did look and seems to be nice to me to start! Do you think you can still mine ETH with laptop still?

Eventually even 4GB won't be enough.  You have to have enough RAM to load the entire DAG into the GPU RAM.  See here: https://investoon.com/tools/dag_size

It says ETH DAG is just barely under 3GB, but 3GB cards have already started to have problems and stop working.  Very soon no 3GB cards will work at all if people even have any that are still working right now.

Laptop?  Ugh....if you're going to mine, take it seriously and get something you can slap 1 or more decent graphics cards in.  Mining with a laptop isn't going to earn you anything and may reduce the life of it if you're not careful.

Thanks!
Increasing VM did the trick. With 36000 it was able to run 10 GPU's and with 40000 all 12. I suppose the theory is size of DAG multiplied with number of GPU's.

I have a problem with my Sapphire RX 570 Nitro+ 8GB: why I get 29 MH/s on Callisto but only 12 MH/s on ETH and ETC??

Update to newer driver and activate Compute.
