32GB DDR5 5600 Desktop Module

This A-Tech module provides 32GB of DDR5 memory at 5600MHz with a CAS latency of CL40. It operates at the standard 1.10V voltage as an unbuffered, non-ECC DIMM. The unit is built as a compatible replacement for the Hynix HMCG88AGBUA part number.

Compatibility and Use Case

This single 32GB stick suits desktop owners who have verified their motherboard supports DDR5 5600 unbuffered non-ECC memory. It is not intended for systems requiring ECC error correction or registered buffered modules. Buyers must confirm their platform accepts this specific speed and density before ordering.

262-Pin DIMM Form Factor

The module uses a 262-pin DIMM form factor as specified for this DDR5 desktop memory. This physical interface determines whether the module seats correctly in the motherboard slot. Always cross-reference this pin count with your system documentation to ensure mechanical and electrical compatibility.

Questions about this item

Will this module fit a standard desktop DDR5 DIMM slot?

Yes, it uses the 288‑pin DDR5 DIMM form factor that current desktop boards expect.

My board only runs memory at 1.1 V — is that compatible?

The module operates at the standard DDR5 voltage of 1.1 V, matching that requirement.

Does the CAS latency of 40 affect everyday responsiveness?

CL40 is the rated timing at 5600 MT/s; the system will apply it automatically for stable operation.
