Claymore CUDA error with 7th card at startup but not all the time

Hi,

I have 7 x GTX 1070 and MSI Z170A motherboard not overclocked and a virtual memory of 16gb.

There are no problems running 6 cards, I have ran that all week.

When I run 7 cards, I have had it running for over 48hrs before I needed to reboot for unrelated things.

If it starts mining on 7 cards then it runs fine.

The problem is when I start the miner, I nearly always get stuck in a loop of DAG errors.

If I leave it running in this state for 5 minutes then it sometimes fixes itself.

Do you have any solutions to not get into this state to begin with? I've spent a few hours unable to get 7 cards running again.

Re: MSI Z170A GAMING M5 - 7 GPU [SOLVED]

I had mine mining for 8 hours on 6 cards, the PC then died and needed a hard reboot. It rebooted and came up with 7 cards working for roughly the same length of time.

I hard rebooted again and with 7 cards I get the CUDA error (never get the CUDA error with 6 cards).

I've also had it mining a few minutes and then get:

GpuMiner cu_k01 failed 6, the launch timed out and was terminated

It's all very random. I've tried -r 180 to try to prevent the 8 hour or so hard reboot issue but it didn't help.

I think I'm on GEN 2, I'll try GEN 1.

I've got the virtual memory set to 16GB, I've tried everything I've read about it.  Sad

Plus the miner has worked for me with 7 cards, just very rarely and until I had to reboot.

hrmmm, and I assume that all cards are over 2GB?

I've been at it about a week now with this board. I'm gonna make another effort tonight, so stay tuned. I'll report back here with my findings. All that said, its been a real ball ache, I could only imagine the BS involved with trying to use the M.2 connections.  Cry

Yep, 1070 4GB cards.

Hi,

I have 7 x Nvidia GTX 1070 with this motherboard and have it running with 6 fine (not overclocking yet).

I am using an M.2. SSD and have 5 cards and 6 USB risers on a 1000W PSU and 2 cards and the M.2. SSD on a 500W PSU.

Sometimes when I reboot one of the cards fails to load (in device manager):

Quote
Windows has stopped this device because it has reported problems. (Code 43)

If I disable / enable the device then it works again.

I have run Display Driver Uninstaller then re-installed the Nvidia drivers but this does not help.

I have swapped the USB cable riser around and used different 3d cards, the hardware is all fine.

Any advice?


To get 8 GPU working in Windows 7, you need to make some changes to the registry to address the code 43 warning.  Problem I had is when I went down to 7 GPUs and back up to 8, the registry hack no longer worked.  I didn't spend too much more time on it before switching to Linux which doesn't have that problem.  Check out the NVIDIA forum post below and try that and it may help.  Supposedly not necessary for Windows 10.

I'm on Windows 10 but tried anyway, it didn't work though. I can occasionally get 7 cards to show without errors but even then I mostly get the error:

CUDA error - cannot allocate big buffer for DAG. Check readme.txt for possible solutions.

I've had it working perfectly with 7 cards a couple of times. Maybe it's time to try SMOS  Huh
