Optiplex XE3 Memory Upgrade
Hello Team,
I have a Dell Optiplex XE3 SFF with an i7 8th Gen. I was trying to upgrade the RAM to 64Gb (32gb x2) but I can't seem to get the unit to post... Not even to go to the bios. Help.

The unit the I have have an 8gb ddr4 stick from Samsung. So I bought some 32gb DDR4 and I thought they're compatible.

Optiplex XE3 Owner's Manual states max supported RAM per DIMM is 16GB.

Ok I forgot to post the link but on this support page it lists 2 x 32 GB as compatible. That must be a typo as both @bradthetechnut and @speedstep state that it is not a compatible configuration.

I think it's definitley a couple of typos as the configuration isn't working. It's not a mix up with the mini tower either. Owner's manual for mini tower also states 16GB max per DIMM, as does spec sheet.

@speedstep @bradthetechnut @JOcean
Thanks for spending your time assisting me with my problem. After around 1 week of research, I figured out that the issue lies with the Processor itself. Since the i7 8th gen is limited to 64GB (total) of RAM @ 2666mhz. Currently I'm running (x2) 16GB @ 2666 plus (x1) 8GB @ 2666.
Since my whole house is running Macs/Chrome Os, I was configuring this unit to be my whole home server running Truenas Scale with Plex/NextCloud/HomeAssistan running in Dockers
Currently, it has an (x2) 10G Nic, (x3) 8TB SSD and about to grow more once I can figure out how to install a driver for my (x8) pcie msata multiplier in TrueNas. But this is the OS's problem now not the hardware.

You're welcome. : )
May be with any luck @speedstep or somebody will have an answer for your driver quest (msata multiplier in TrueNas).

Are you using NON-ECC RAM? You can try pulling the CMOS battery out for 15 minutes then reinstalling the battery. Are you using Crucial RAM as Dell systems are very picky about RAM makes.
One interesting point though. The specs listed on the support page are different from the spec sheet here. The support page lists 2 x 32 GB as compatible but the spec sheet here only shows 4 x 16 GB as compatible for 64 GB total.
