Hey all
I've got two Dell Optiplex 3080 micro's. i5-10500t
one with 2x8gb and the other with 1x8gb memory.

Looking to upgrade one or both units.

First is my daily driver and the second will replace a Lenovo M93p with i7-4785t 16gb mem for server purposes.

daily driver is for very basic use... browsing, email, light gaming, the odd VM or remote desktop use. its a general tinker box but nothing hardcore

the server will be for plex, NAS, VMs, download box.

does dual channel only work with matched capacities? so im thinking of either getting 2x16gb sticks or a single 32gb stick to get 40gb total for the server... or i could acheive 24gb on both machines but not sure if thats pointless as the daily driver probably wont make use of it and not sure if im robbing myself of dual channel mode in the main rig?

any adivce is welcome.

cheers!
 
Dual channel will operate at the max capacity of the two channels on the board, by which I mean, if you have 1x8GB and 1x32GB, then you'll get 24GB in single channel.

32GB sticks can have more compatibility issues than 16GB or less though, but 10th gen is fairly new so should be able to accommodate this.

Safest option would be to just sell the 8GB (or stick it in the 2x8GB system, if a slot is available) and buy 2x16. At lower speeds (which OEMs use) compatibility is always less of an issue though.

You may find that you can't change frequency or voltage in the bios, so if so, I'd avoid gaming memory that relies on XMP.

thanks for the info. just so I understand this properly. the first point you made there... does that mean 24gb in total usable mem or 16gb working in dual channel and the remaining 24gb working in single channel modes?

16gb dual channel rest in single channel, total usable is all the memory.

Plex works with 4gb of ram. No need to add any more. I run a 4k plex server with 8gb and have no problems over 4 streams.
What plex needs is cpu power but even then and old quad core is fine.

Edit just seen your wanting to run vm’s
