LGA 1851 overclocking platform

The ROG Maximus Z890 Apex is an ATX motherboard built for Intel Core Ultra processors (Series 2) using the LGA 1851 socket. It targets enthusiasts and competitive overclockers who need maximum CPU and memory headroom. The two-slot DDR5 layout and robust power delivery are engineered specifically for record-breaking performance attempts.

22+2+1+2 power stage design

This board replaces earlier Z790 Apex models with a revised 22(110A)+2(90A)+1(90A)+2(80A) power stage array fed by ProCool II connectors. The jump is worth it when pushing DDR5 beyond 9600 MT/s or running sustained heavy loads on Intel Core Ultra chips. MicroFine alloy chokes and metallic capacitors ensure stable voltage under extreme tuning scenarios.

Dual-slot DDR5 memory focus

The two 288-pin slots support up to 128GB dual-channel DDR5 with XMP 3.0 and AEMP III profiles. This suits overclockers who prioritise memory frequency over capacity and use high-binned CUDIMM kits. Builders needing four populated slots or ECC support should look at alternative Z890 boards with standard four-DIMM layouts.

Questions about this item

What size DDR5 modules and how many slots does the ROG MAXIMUS Z890 APEX accept?

The board has two 288-pin DDR5 slots supporting modules up to 128GB total capacity.

Which CPU power connectors must be seated for the 22+2+1+2 stage VRM on this motherboard?

Both ProCool II 8-pin connectors need to be fully inserted; the lower one is often missed in tight builds.

How do I update the BIOS on the ROG MAXIMUS Z890 APEX without a CPU installed?

Use the USB BIOS FlashBack port on the rear I/O with a formatted USB drive and the latest firmware file.
