Hi Claymore

Have you managed to replicate the issue with 12 gpu systems
issue: on version 9.8 if you have more than 3 amd cards in a rig of 11 or 12 gpus ethdcrminer hangs on Algorith ASM, if you start the instance with 3 amd cards and the rest nvidia then it starts mining. then you have to start another instance of ethdcrminer with the remaining cards, .
This issue was also experienced by a youtube channel Cryptomined where he had to have multiple instances on 9.8 running in order to use all the cards.
When all cards are selected after the cmd window hangs nothing but a hard reset solves the hang.
Hope that helps, if you need any more info or troubleshhooting with this regards you can let me know.
thanks

I don't have appropriate hardware to test 12GPUs configuration. You can try some different miner to check if it is more stable, because the reason can be not in miner. Also try "-gser 1" or "-gser 2" option.

I think there is a software problem and I will explain why I think that.

I am running multiple 13 GPU rigs all of them equipped with ASRock H110 Pro BTC+ , all of them have a mix of RX 580 8GB and Nvidia cards, running 7/8 RX and rest Nvidia.

The Nvidia is farming an different software with zcash , the RX all use Claymore Dual Mining.

What is the problem:

When I use -di with more then 3 AMD cards , the software refuse to start. Windows doesn't frozen PC is still running but the Claymore remains frozen at GPU #x: algorithm ASM
If I use -di 012 for example (maxim 3 AMD Cards) the software runes perfect, so basic for 7 GPU , I need to run 3 Claymore miner's with -di 012 , di 345 , di 6 (any other with more then 3 cards will frozen the software)

What combination I try:

- If I disable ASM , it get frozen at POOL/SOLO version, so is not an ASM problem.
- I tested multiple Claymore Dual mining software, 9.8 / 9.7 etc, with different AMD drivers, mixed old drivers, latest block chain driver , or the newest one available on website, same story for all
- Also I tested on all miners gser 1 and gser 2 option from the manual , is not working.
- If I enable 3 AMD cards and 5 Nvidia cards, is working fine, the problem is just for AMD cards over 3 enabled
- I increase my virtual memory on one rig from up to 60GB , it didn't help.
- I tested the software with dual mining enable and ETH mode only, and any other possible combination from Claymore manual.

Note: the zcash software is turned off during this tests , so no other program to interfere with Claymore miner.

I appreciate your work and I hope you can find a solution for this problem, special that lot of motherboard vendors announces mining boards with lot's of PCIe slots, Ex ASUS 19 GPU slots.
Thanks,
