I just built the FW 13 HX370 DIY edition and I have two 16 GB RAM sticks from Corsair. (DDR5, 5600). Sadly when there’s any of the two sticks in the channel 1 slot it doesn’t boot and I get a funky LED status (see video: https://youtube.com/shorts/ZY5MDsGS3w4?feature=share)
Either of the sticks work in the channel 0 slot though.
Any idea of what’s wrong here?
Contact support. That’s POST code 0xC5, which indicates a RAM error, and based on your testing, the channel on slot 1 isn’t working right (since both sticks work in channel 0).
