Nvme and overclocking causes crash

Support
1

i installed the NVMe Base for Raspberry Pi 5 – NVMe Base and it was running just fine… actually perfect. i tried to impliment the 3g “overclockiing” that Raspberry says is perfectly ok and stable. it rebooted and all i get is a black screen… i have to remove the cable to the nvmw cable and reinstall the os on a flash card and restart the entire installation nvme again…

is this a known issue?

What is “3g overclocking”? If you are talking about PCIe Gen3, then the situation is different. The Raspberry Pi Foundation explicitly states that this is not supported and may or may not work (https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#pcie-gen-3-0)

The overclocking of the cou and gpu.

# Tell the DVFS algorithm to increase voltage by this amount (in µV; default 0).
# IMPORTANT: See note below
over_voltage_delta=50000

# Set the Arm A76 core frequency (in MHz; default 2400).
arm_freq=3000

# Set the VideoCore VII core frequency (in MHz; default 800).
gpu_freq=1000

Ok, I misunderstood your initial post. Regarding gpu_freq, the docs state:

“It is recommended when overclocking to use the individual frequency settings (isp_freq, v3d_freq etc) rather than gpu_freq, because the maximum stable frequency will be different for ISP, V3D, HEVC etc.”

Maybe this is the reason for your crash?!

Sorry, i was frustrated and unclear. My apologies.

Thank you i will try that
