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.

    Since you’re upgrading, measure it against the stick you removed.

    Also, you sure you’re not just putting it in backwards? Some put chips and stickers on one side, some on the other. There’s no front or back to RAM.
