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,
Miner does not care about how many cards are used, it just calls OpenCL. So it can be drivers-related problem. What if you start Genoil miner? Yeah vendors announce mining boards with 12-19 PCIe slots, but drivers fail to support it properly, at least in Windows.
