A-Tech 32GB DDR5 4800 DIMM

This 32GB DDR5 module runs at 4800MHz with CL40 latency and 1.10V operation. It uses a 2Rx8 Micron chipset on a 288-pin unbuffered non-ECC PCB. The stick carries Supermicro certification for validated compatibility.

Suited for Supermicro DDR5 systems

Ideal for upgrading compatible Supermicro workstations or servers that require certified DDR5 4800 memory. Not intended for platforms that demand registered ECC modules or speeds beyond the tested 4800MHz frequency.

Straightforward 288-pin installation

Align the notch with the motherboard slot and press firmly until the retention clips engage. Common issues include mixing this unbuffered DIMM with registered memory or skipping the BIOS update required for full 4800MHz operation.

Questions about this item

What motherboard slot does this 288-pin DDR5 DIMM require?

A motherboard with a 288-pin DDR5 DIMM slot is required for this module to fit and function.

Will this 4800 MHz DDR5 module run at full speed on a system that only supports lower DDR5 speeds?

The module will downclock to match the highest DDR5 speed the motherboard and CPU officially support, so it will run at that lower speed instead of 4800 MHz.

How can I confirm this 32 GB module is operating at CL40 after installation?

Check the memory timing readout in the BIOS or a system-information tool; it should show CAS latency 40 when the kit is running at its rated 4800 MHz.
