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.
More details, the motherboard is a SuperMicro H13SAE-MF. Its manual says it supports ECC/Non ECC UDIMM DDR5. I'm out of the loop, but I believe UDIMM means "unregistered," which would explain why my RDIMM isn't compatible, but the SuperMicro website compatibility checker suggests ~~this stick which says ECC REG DIMM in its detailed description.~~ wrong, that's the ER version. The checker suggests EU.
What's going on?
