Question ASRock x570 Phantom Gaming 4 128GB ECC RAM?

[cij]

Hello,

I have purchased an ASRock x570 Phantom Gaming 4 Motherboard with an Ryzen 7 3700X. I would like to run my setup with 4x 32 GB ECC RAM. I have purchased 4x Samsung M393A4K40CB2-CTD7Q 32GB ECC Rams and have already updated my Bios to the lates version 2.0 with other non ECC RAM. After the BIOS update, I have installed the new purchased RAM, but the system is not starting after installing the new RAM. I can only see a black screen. Is there any way or do I need change a setting in the BIOS to run the ECC RAM?

Thanks in advanced

Those are RDIMMs, Registered (Buffered) DIMMs. Your mobo only supports unbuffered memory.

Hello, but what means this from the official ASRock website;

Here I can find the information for ECC & non-ECC, un-buffered memory RAM

The specs list support for un-buffered RAM only. The stuff you bought is buffered. That's why it doesn't work.

oh okay understood now. Thanks for your fast help!

You're welcome! If you still want to find some ECC memory, try to find some ECC UDIMMs. The "U" stands for "un-buffered".
