32GB DDR5 4800 desktop memory

This 32GB DDR5 4800 module is a compatible replacement for Hynix HMCG88MEBUA081N and related part numbers. It fits standard 288-pin DIMM slots in desktop computers. The unbuffered, non-ECC design suits consumer platforms.

Practical limits of DDR5 4800

DDR5 4800 operates at 1.10V with a tested frequency of 4800 MT/s and CAS latency of CL40. The PC5-38400 bandwidth rating reflects the peak transfer rate of this standard. Unbuffered modules rely on the memory controller for signal integrity.

CL40 latency at 4800 MT/s

The CL40 timing at 4800 MT/s determines how quickly the module responds to read requests. This latency figure is the primary specification to check against your system requirements. Verify that your motherboard and CPU support this speed and timing combination before purchase.

Questions about this item

Should I pick the HMCG88MEBUA081N or the HMCG88AEBUA084N version?

Both part numbers appear in the compatibility list; this module replaces either one.

What does the 4800 speed rating mean once the module is installed?

The module runs at 4800 MT/s with CL40 latency at the standard 1.10 V DDR5 voltage.

Does the 262-pin DIMM fit a standard 288-pin DDR5 desktop slot?

The product is a 288-pin DDR5 UDIMM; the 262-pin figure in the data is a typo.
