raspberry pi 400 wont boot blinking green light 8 times bad ram

Post by Jgarces »

ive already tried multiple times using different SD cards and USB with different raspberry pi OS. monitor works seen it show up a few times when trying different OS but would not boot up. PRIOR to it no longer working it was freezing randomly when just on a simple screen and not running anything example retro pie select screen or ubuntu desktop. I tried installing fresh OS and kept crashing and finally just wouldn't boot up. Green light just flashes 8 time fast. If I unplug for a while the green light will stay on, but nothing will happen and when I try again same thing with green light 8 fast flashes.

Have you been using the current version of Pi OS Bullseye? The 8 times ACT green LED blink can mean SDRAM not recognized/damaged or that the bootloader is too old.
8 flashes: SDRAM not recognized. You need a newer bootcode. bin/start. elf firmware, or your SDRAM is damaged
When did you purchase the Pi 400 from Adafruit?

Yes using the latest OS. Tried using the general OS and the one specific to the 400

Also tried updating the boot using USB and SD and no luck

Purchased 6/18/2022

Since you are using a current OS this is most likely an SDRAM issue. It is outside the Adafruit warranty period so you will need to purchase a replacement.
