Synology proprietary RAM D4ES03-4G arrival? Is it real? - Yuma - 07-19-2023
Hi,
I'm new here and if I am doing anything wrong I will apologize in advance.
I've been looking for proprietary RAM for my Synology DS923+ in the 2nd hand market (in Japan) and I found something that looked to be good but I wasn't sure.
The D4ES03-4G
(in attachment photo because I couldn't post a link)
The seller claims that he/she got this out of the DS923+ that he/she bought.
This must be the successor to D4ES02-4G but I can't seem to see any info on Synology or google.
I was wondering does everyone think this is real? Should I go for it and mix and mach it with my DS923+ that has a D4ES02-4G installed?
Hoping to here anyone's thoughts.
Thank you,

Hi ed,
Thank you very much for your advice.
The seller lowered the price to 3,980JPY (≒28.07USD≒21.83GBP) so went for it.
It is not on the compatibility list but I will bet on it being added to the compatibility list and I believe that synology must have tested a mix configuration of D4ES03-4G and D4ES02-4G if they are using it for newly manufactured DS923+.
I think I will share my test results with every one here after I get my hands on it.
Thank you again for your advice.

Hi
I've got the D4ES03-4G!
It looks pretty alike D4ES02-4G.
DSM on DS923+ is recognizing it OK. No Warning's in DSM 7.2-64570 Update 1.
RAM test passed.
