Title: M.2 adaptor not detected
Post by: yoyoma1 on January 03, 2018, 10:57:48 AM
Hello I am having problems with this motherboard  Gigabyte GA-Z270P-D3 - I plugged into the M.2 adapter but it is not detected in windows despite the fan spinning on the GPU? I've updated the bios to the mining version. I have tried the suggestions on this threadhttps://bitcointalk.org/index.php?topic=2204115.msg22438508#msg22438508 (https://bitcointalk.org/index.php?topic=2204115.msg22438508#msg22438508)

Any ideas? It seems that it should work.....

Did you make some changes in the BIOS settings of the motherboard?
There is an option - M2 adapter mode which is to be set to PCIe for GPU.

Thank you! I hope there is - Could you guide me to where in the BIOS this is? I thought there may be an option here but could't find anything.

If there is a BIOS update, you could install that so that new options appear (usually the case with older MOBO's to enhance mining stability of which the features came later)

Also I tried the same, but in my case the M.2 channel is shared with the SATA channel to which my SSD is connected, so my motherboard does not support the usage of the M.2 connection for a GPU.
I found this out by reading the technical datasheet of systemboard.

Good luck!

I have already updated it to the mining bios F6a and gigabyte say it should support 7 Gpus using the M.2 https://www.gigabyte.com/MicroSite/462/mining.html (https://www.gigabyte.com/MicroSite/462/mining.html)

I think if the fan spins on the GPU it suggests that the adapter itself is ok and it is a configuration/software issue but how to fix it I don't know - maybe something in BIOS as you have said.....

I had a quick look to https://bitcointalk.org/index.php?topic=2204115.msg22438508#msg22438508 and saw no mentioning of the above 4g decoding, which helped me out before to see the GPUs in device manager in windows;

“Above 4G Decoding” setting from “Disabled" to “Enabled”

Setting the PCI to Gen1 was mentioned I believe, these two settings are often ''the'' BIOS settings

Did you rule out the power? You could disconnect all other GPUs and connect one through primary slot for the monitor and the second on the M.2 slot.
