Title: MSI Z270 Gaming M5 second M2 slot issue Post by: 4ndy on January 09, 2018, 05:04:25 AM Hi everyone,
does anyone tried to work on Z270 Gaming M5 M2_2 slot (second slot)? I am able to get M2_1 (close to CPU) detect my GPU but when i have both GPU on M2_1 and M2_2 windows 10 only detect M2_1 GPU but not M2_2 GPU. And, i tried to swap M.2 to PCIE adapter and i get same result too....not really sure what is the issue here, i thought both M.2 slot are the same. any help will appreciated. Thanks. BIOS updated version 4G Decoding enabled Title: Re: MSI Z270 Gaming M5 second M2 slot issue Post by: timbereagle on January 09, 2018, 05:28:26 AM Hi everyone, does anyone tried to work on Z270 Gaming M5 M2_2 slot (second slot)?

BIOS updated version 4G Decoding enabled I used MSI Z170 M5 and also M3. Both of them only 1 of M2 slot works, I could not make 2nd M2 to work.

I think Z270 has better native m2 support than z170.
This weekend i will try use both sockets for two pcie adapters. Title: Re: MSI Z270 Gaming M5 second M2 slot issue Post by: 4ndy on January 09, 2018, 02:58:42 PM I have contacted MSI support team. They told me it is adapter design issue, and asked me to do this "manually short circuited the seventy-third and seventy-fifth pins on adapter to make the seventy-fifth pin defined as ground for a try" I am not really sure it will burn the motherboard, still not confident to do it.
