Product Identity

This A-Tech module is a 32GB DDR4 2933MHz desktop DIMM built as a direct replacement for HP part L89423-001. It runs at 1.20V with CL21 latency and uses unbuffered non-ECC chips on a 288-pin PCB. The single stick delivers 32GB of capacity for mainstream desktop workloads.

Ideal Use Case

The kit suits owners of compatible HP desktops needing a straightforward 32GB upgrade without ECC or registered buffering. Systems that require registered memory, ECC error correction, or speeds beyond 2933MHz should consider different modules. Verify your motherboard accepts 2Rx8 unbuffered DDR4 before ordering.

Deciding Specification

The 2933MHz CL21 rating at 1.20V is the single figure that determines fit. If your platform specifies DDR4-2933 non-ECC UDIMM at this voltage the module will operate at its rated speed. A different speed grade or voltage requirement means this part will not match the system profile.

Questions about this item

Will this 32GB module work in a system that specifies the HP L89423-001 part number?

Yes, it is built as a direct replacement for that HP part number and matches the DDR4 2933MHz PC4-23400 specification.

Does the module need a heat spreader to run at 2933MHz?

No, it operates at the standard 1.2V DDR4 voltage without a heat spreader and has been tested at 2933MHz.

Can I install this in a motherboard that only has 262-pin SO-DIMM slots?

No, this is a 288-pin DIMM for desktop boards; it will not fit 262-pin laptop slots.
