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.
Didn't see anything about ECC being a different size for UDIMM and RDIMM (from a quick search).
That data sheet says "Tolerances on all dimensions are ±0.15 (millimeters)". Perhaps it's just a tight fit - does it look like it will almost fit? It wouldn't be anything to do with the motherboard RAM slots, like they need to be "opened" fully?
This is pushed all the way to the right.
