48GB DDR5 4800 UDIMM for ASUS ROG Strix Z890-E

This 48GB DDR5 4800 CL40 module is built for the ASUS ROG Strix Z890-E Gaming WiFi motherboard. It runs at 1.10V as a 2Rx8 unbuffered non-ECC UDIMM. The 288-pin design fits the board's desktop memory slots directly.

System-specific upgrade for compatible DDR5 boards

It suits owners of the named ASUS motherboard who need a single 48GB stick without a heat spreader. It is not for builds that require ECC error correction or registered buffering. It is also not for platforms that cannot accept a 2Rx8 48GB density module.

CL40 latency at 4800 MT/s decides fit

The CAS latency of CL40 at the 4800 MT/s data rate is the key timing figure. Builders should confirm the motherboard qualifies this exact latency and rank configuration before purchase. The 1.10V operating voltage matches the standard DDR5 baseline for this speed grade.

Questions about this item

Does this module fit an ASUS ROG Strix Z890-E motherboard?

It is built for the ASUS ROG Strix Z890-E Gaming WiFi board as a 288-pin DDR5 4800 UDIMM.

Will this 48 GB DDR5 4800 module run with older DDR5 sticks I already have?

Mixing ranks or speeds can cause instability; for best results use identical 2Rx8 CL40 1.10 V modules in matched pairs.

How do I verify the 48 GB 4800 MT/s kit is operating correctly after install?

Enter the UEFI and confirm the memory reads 48 GB at 4800 MT/s with CL40 timings and 1.10 V applied.
