32GB DDR5 kit for ASUS Z890 APEX

This 32GB kit contains two 16GB DDR5 UDIMM modules validated for the ASUS ROG Maximus Z890 APEX motherboard. It targets builders upgrading that specific platform with matched, unbuffered memory.

CL40 latency at 4800 MT/s

The modules run at DDR5 4800 (PC5-38400) with a CAS latency of CL40 and 1.10V operation. This timing is the decisive specification; systems requiring different latency or voltage will not be compatible.

Dual-rank headroom for heavy workloads

Each 16GB module uses a 1Rx8 organisation, giving 32GB total capacity for multi-threaded applications and large datasets. Workloads that exceed 32GB will require additional DIMM slots or higher-density modules.

Questions about this item

What real-world bandwidth does the DDR5 4800 rating deliver on the ASUS ROG Maximus Z890 APEX?

The kit runs at DDR5 4800 (PC5-38400) so each module transfers data at up to 4800 MT/s when the board enables the rated profile.

Does the CL40 latency and 1.10 V voltage work with the standard DDR5 UDIMM slot specification?

Yes — the modules are standard 288-pin DDR5 UDIMMs rated CL40 at 1.10 V, matching the JEDEC base specification for unbuffered non-ECC memory.

Will the two 16 GB sticks physically fit the four DIMM slots on that motherboard without a heat spreader?

Each stick is a bare 288-pin UDIMM with no heat spreader, so they occupy only the standard slot height and leave clearance for large CPU coolers.
