What this barebone is

The ASUS ExpertCenter PB64 90MR01C1-M001E0 is a new 1.35L mini-PC barebone built around the Intel Core Ultra 7 265 processor with integrated Intel Graphics. It ships without memory or storage, leaving two DDR5 SO-DIMM slots ready for up to 64GB dual-channel RAM and dual M.2 2280 PCIe Gen4x4 slots plus a 2.5 inch SATA bay for local drives. WiFi 7 and Bluetooth 5.4 provide modern wireless connectivity.

Who should buy this and who should not

System integrators and IT teams wanting a compact, VESA-mountable desktop with tool-less chassis access for quick deployment will fit this unit. Buyers who need discrete graphics, additional PCIe expansion slots, or a system pre-populated with RAM and an operating system should look at a larger workstation or a configured mini-PC instead.

Memory and storage capacity you must supply

You must add two DDR5 SO-DIMMs for up to 64GB total and at least one M.2 2280 NVMe SSD or 2.5 inch SATA drive because the barebone arrives with zero memory and zero storage installed. The board supports dual-channel DDR5 at 262Pin and PCIe Gen4x4 on each M.2 slot, so capacity and speed depend entirely on the modules you choose.

Questions about this item

What DDR5 SO-DIMM modules do I need to install before this barebone will boot?

You must add two 262-pin DDR5 SO-DIMMs, up to 64 GB total, to fill the dual-channel memory slots.

Can I keep my existing 2.5-inch SATA hard drive and M.2 NVMe SSD when moving to this unit?

Yes, the chassis provides one 2.5-inch SATA 6 Gb/s bay for 7 mm drives and two M.2 2280 PCIe Gen4 x4 slots for NVMe SSDs.

How can I verify the system is using both memory channels after I install the RAM?

Enter the BIOS or use a system-information tool; it will report dual-channel mode when two matched modules are detected in the two SO-DIMM slots.
