Certified Server Module for High-Density DDR4

This A-Tech Supermicro Certified module delivers 64GB of DDR4 2666 memory in a single LRDIMM. It uses a 4Rx4 quad-rank layout with ECC and load-reduced buffering to maximise capacity per slot. The module operates at standard 1.20V with CL19 latency and is built with Hynix components validated for Supermicro platforms.

Suited for Supermicro Servers Needing Maximum DIMM

Administrators expanding memory in qualified Supermicro systems that support LRDIMM technology will benefit from this certified part. It is not for workstations or consumer boards that only accept standard UDIMM or RDIMM modules. Buyers who need non-ECC memory or lower-voltage operation should look at other product lines.

Quad-Rank 4Rx4 LRDIMM Architecture Determines

The 4Rx4 organisation and load-reduced signalling define which motherboards can address this 64GB capacity at 2666 MT/s. Systems must explicitly support quad-rank LRDIMM population rules to recognise the full module. Verify the platform qualified vendor list before ordering.

Perguntas sobre este artigo

Will this 288‑pin LRDIMM fit my Supermicro server’s DDR4 memory slots?

The module uses the standard 288‑pin DDR4 LRDIMM form factor, so it fits any server board that accepts DDR4 load‑reduced DIMMs.

What BIOS setting or slot population rule is commonly missed when installing this quad‑rank 4Rx4 module?

Quad‑rank 4Rx4 LRDIMMs often require specific slot ordering and a BIOS memory‑mode change; consult the server manual for the supported population sequence.

How can I tell when this 64 GB DDR4 2666 module should be replaced?

Replace the module if the system logs uncorrectable ECC errors, fails memory diagnostics, or shows repeated boot failures after ruling out other causes.
