Am I a moron? or is something up with this RAM? (lemmy.world)

Upgrading a server for the first time in 10 years, so I’m a little out of the loop. I was surprised to find that the RAM I bought didn’t fit.

This is my first time dabbling in ECC RAM, so I figured there was some minor detail I missed when purchasing, but I eventually came across the data sheet for this stick, and the dimensions given don’t match the measurements I’m making. The tip of the caliper should be in the middle of the notch at 68.1mm.

What’s more is that the dimensions in the data sheet seem to match the dimensions on my motherboard. What’s going on here?

[SOLVED] I and Kingston are morons. I ordered RDIMM instead of UDIMM. The Kingston datasheet gives the wrong dimensions.

oddly hard to find online.

Right? I was hoping for like a wikipedia page with the dimensions of every kind of DIMM. Might have to make one...

So I think you're right. The only explanation is that I ordered RDIMM instead of UDIMM and that Kingston messed up.

I just double checked, the compatibility checker suggested the -EU variant, but I was looking at -ER. (Un/Registered).

It doesn't help that ECC and registered get interchanged a bit it seems.
