Server RAM Speed Matter?

[OzoneSea]

I've been looking at upgrading the RAM in my home lab (mainly capacity but possibly speed) and noticed that my RAM is currently DDR4-1866 which is the slowest speed the motherboard/CPUs support. Would it make any meaningful performance improvement if I upgraded to DDR4-2400 memory? The homelab hosts several things, all through Proxmox. Mainly web services (NextCloud, GitLab, Jellyfin, Pterodactyl, etc.) as well as some game servers such as Minecraft and Satisfactory. The only compute heavy tasks I have are software transcoding in Jellyfin and F@H in the winter.

You might see a small improvement in Jellyfin if the cpu is encoding but nothing noticeable in any of those other tasks I think.

Server OSes typically recommend not even enabling XMP as the small potential performance gain isn't worth the risk of instability.

From my understanding, the DDR4-2400 memory doesn't use XMP/EXPO. It's the standard JEDEC speed. But if I won't see much of an improvement in performance over DDR4-1866 then I'll probably just stick with the slower speed

always depends on workload too... idk ddr4 should be dirt cheap by now... just try it out?  as long you don't enable XMP or overclock stability shouldn't be an issue.
