Replacement for HP N02931-001

This A-Tech module is a 32GB DDR5 DIMM built to match the HP N02931-001 specification. It runs at 4800 MHz with CL40 latency at 1.10V and uses a standard 288-pin desktop form factor. The kit contains one unbuffered non-ECC stick tested for reliable operation in compatible HP desktops.

Suitable for HP desktop upgrades

The module suits owners of HP systems that list N02931-001 as the approved part number and need a single 32GB DDR5 4800 stick. Builders using platforms that require registered memory, ECC support, or a different pin count should look at other products. Always confirm the motherboard qualifies for this exact HP part before purchasing.

288-pin DDR5 DIMM form factor

The decisive specification is the 288-pin DDR5 DIMM interface, which only fits motherboards with DDR5 slots. A 262-pin module or any other generation will not seat in the same socket. Verify the board accepts DDR5 4800 unbuffered non-ECC memory before ordering.

Questions about this item

Will this 32 GB DDR5 4800 CL40 1.10 V DIMM fit a desktop that originally shipped with HP part N02931-001?

Yes, the module is built as a direct replacement for HP N02931-001 and uses the standard 288-pin DDR5 DIMM form factor.

Does the kit require any special motherboard features such as ECC or registered memory support?

No, the module is a non-ECC unbuffered DIMM, so it works with ordinary consumer desktop boards that accept standard DDR5 memory.

What voltage does the module run at and is it within the normal DDR5 range?

It operates at 1.10 V, which is the standard DDR5 voltage, so no manual voltage adjustment is needed.
