32 GB DDR5 desktop module

This 32 GB DDR5 module is built for desktop, workstation, NAS and all-in-one systems that accept standard 288-pin unbuffered DIMMs. It replaces Hynix parts HMCG88MEBUA081N and HMCG88MEBUA084N with a direct-fit upgrade.

JEDEC DDR5 4800 CL40 limits

The module runs at the JEDEC-standard 4800 MT/s with CL40 latency at 1.1 V. Because it follows the base DDR5 specification, it will operate at this speed on any compatible platform without manual tuning or overclocking headroom.

Tool-free DIMM installation

Installation is a simple DIY step: align the notch, press the module into the slot until the retention clips click, and power on. The most common issue is the system failing to POST when the DIMM is not fully seated or when mixed with modules of different speeds or ranks.

Questions about this item

Will this 32 GB DDR5 module fit a standard 288-pin desktop DIMM slot?

Yes, it is a 288-pin unbuffered DIMM built to JEDEC DDR5 specifications for desktop, workstation, NAS and all-in-one systems.

Does the module require ECC support from the motherboard?

No, it is a non-ECC unbuffered module, so it works on any consumer desktop board that accepts standard DDR5 memory.

What voltage does the memory run at and is it within standard limits?

It operates at 1.1 V, the standard JEDEC voltage for DDR5, so no manual voltage adjustment is needed.
