Raspberry OS crashes after 20 min running from NVME SSD Samsung 970 EVO

2024-12-05 23:45:14 Ask

Hello, I got this kit and followed the instructions here and other sites about booting from NVME SSD.

I got a 970EVOPlus from Samsung (1TB), and it boots correctly, but after some time, lets say 20 minutes, the Raspberry OS starts slowing down, icons change color, and then suddenly everything stops. I need to restart the whole system. Then, it looks since the circuits are "warm", it takes about 5 to 10 minutes for the system to hang.

When I run the system with SD card it works OK for days. The SSD I have used it on other PCs with an USB adapter and see no issue with it.

I read on reddit that there is a cicuit to limit current for this M.2 adapter. Is that correct? What would that limit be? is there a way to augment that limit?

I have connected  the red and black harness to supply the 5 V from the Pi5 Connector Adapter (HDMI adapter/Power), to the M.2 adapter.  

What is the purpose of the yellow pin connector that states "GND 5V"? Is that to get more power?

The NVME m.2 SSD model is MZ-V7S1T0, 970 EVO Plus, Samsung NVME 1TB. It is rated 3.3V 2.7A DC. That would mean 8.91 W. Is that something that the adapter can handle?

】The PCIE cable has a power limit of 5W.

】If the power exceeds this, please connect the yellow pin connector marked "GND 5V" to the 5V and GND of the Raspberry Pi to obtain additional power.

】After the additional power supply, the maximum output of 3.3V is 3A, and the total power consumption is 9.9W.
