Hi claymore and all,

My rig has 7 gpu.

I'm using biostar TB250-btc motherboard with 1050 Supersonic PSU.
Running 7 1070 Windforce OC 8GB gpu.

My rig can run from 1 to 2 days.

However, upon facing error, i have set -r 1 to trigger a reboot.bat to rs it.

This is where to problem occurs.

When my system restart and the claymore miners starts, it couldn't detect my gpu and starts prompting the error below:

No NVIDIA CUDA GPUs detected.
No AMD OPENCL or NVIDIA CUDA GPUs found, exit

The error just kept repeating itself.

The miner doesn't restart and this error doesn't trigger my -r 1 reboot.bat as well.

How do i solve it: i will have to manually restart my rig and sometimes i will have to do it 2 - 3 times till it detects again.

Any idea how to fix this problem or anyway to allow the system to restart upon facing not being able to detect GPUs?

Please help me out guys.

Thank you!

Reinstall GPU drivers

May i know what's the best driver to use?

I'm using 372.54 NVIDIA driver which is recommended by Claymore himself.
but still having problems now and then for unable to detect gpu after system rebooting.

I always use latest drivers. My rigs never crash, dont slowdown and I get same or better hashrate than previous versions (yes, I always install the latest).
Im currently using etherminer with my Nvidia cards but I never had a single problem with Claymore (any versions) dual or not.

Hi,

thanks for replying.

so i assumed you are using the latest NVIDIA driver 385.28?

is it working fine for claymore miner ?
because i have previously tried upgrading to higher drivers and after a 10mins run, it gives me a gpu error.

i tried to troubleshoot and ended up rolling back my drivers and found this workable driver which is 372.54.
But however, it still have some problem whenever my system restarts, it cant detect the gpu.

Do you think it may not be just driver issues?

last time I used Claymore (9.8 over Windows 10 64bit) with my Nvidia cards, I was using version 384.94 since the day it was released and I had no issue. Those cards are still running that version but with etherminer but thanks to you, I will upgrade today

.

I dont plan to go back to Claymore with those cards for now but Ill run a 60 minutes test and report back.

reporting back, no crash while dual mining Sia. Same hashrate too.

Can i know how many GPUs and what GPUs do you have?

Also, what watt PSU are you using right now?

I'm running at around 1000watt on a 1050watt PSU.
Not sure is this the reason why it has problem detecting my GPU whenever the system restarts.

Or its just purely driver issue.
