256GB DDR4 ECC RDIMM kit for HP ProLiant XL270d

This 256GB kit contains four 64GB DDR4 2933 PC4-23400 CL21 registered ECC modules. It is built for the HP ProLiant XL270d Gen10 server and runs at 1.2V with a 2Rx4 organisation. The modules use the standard 288-pin RDIMM form factor and contain no heat spreaders.

Who this suits and who should look elsewhere

This memory fits administrators upgrading or repairing an HP ProLiant XL270d Gen10 that requires registered ECC DDR4. It will not work in standard desktop PCs or consumer motherboards that accept only unbuffered non-ECC DIMMs. Buyers needing load-reduced ECC modules or a different capacity per DIMM should choose another kit.

288-pin registered ECC DDR4 form factor

The modules are 288-pin DDR4 registered ECC RDIMMs, a physical and electrical standard that only fits server and workstation boards designed for registered memory. If the target system calls for unbuffered ECC or load-reduced DIMMs, these modules will not be compatible.

Questions about this item

Does the 288-pin DDR4 RDIMM form factor fit the HP ProLiant XL270d Gen10 memory slots?

Yes, the 288-pin DDR4 ECC Registered DIMM matches the slot layout of the HP ProLiant XL270d Gen10 server.

What is the correct installation sequence for the four 64 GB modules in the XL270d Gen10?

Populate all four DIMM slots following the server's channel population guide; the common mistake is mixing registered ECC with unbuffered or load-reduced modules, which this kit avoids.

Will the 1.2 V DDR4 2933 modules need replacement if the server runs at 2133, 2400 or 2666 MT/s?

No, the kit is backward compatible with 2133, 2400 and 2666 MT/s operation, so the same modules remain valid across those speeds.
