Ram compatibility help

[JoeTheBuilder]

Hello, so I have a X399 Taichi motherboard from asrock and got some ram for it and it looks to not be posting with the different ram.

 

The motherboard says it supports un-buffed memory and that is what I got.

 

The specific ram I got was:

OWC 128GB (4x32GB) DDR4 3200MHz PC4-25600 CL22 2RX8 ECC Unbuffered UDIMM 1.2V 288-pin Workstation Server Memory

 

On the box it says the following:

OWC 128GB 4x32GB D4-3200 2R8 EDIMM 288p

 

I tried searching what EDIMM memory is, and could not find anything so I think it might be a typo

 

The only thing I can think about for why the ram might not be working is because my motherboard says it supports 3200(OC), and I am guessing it is trying to say over clock for XMP. Maybe XMP does not exist for ECC memory?

 

I am a pretty novice PC builder so if there is something I did not understand I would like to know.

Uhhh, so I turned off the machine and turned it back on again, and now it looks to work. It gave me a screen saying the ram has changed. I think during boot I was spamming the f keys to get into the BIOS and that broke it? Anyways we are all good now!

Try turning it off and back on
