A-Tech 32GB DDR4 2400MHz ECC LRDIMM

This A-Tech module delivers 32GB of DDR4 server memory at 2400MHz with ECC Load Reduced technology. It uses a 288-pin LRDIMM form factor and operates at 1.2V standard voltage with CL17 latency. The quad-rank 4Rx4 design is certified for Supermicro systems using the MEM-DR432L-HL01-LR24 specification.

Suited for Supermicro servers needing maximum

This module fits administrators expanding memory in qualified Supermicro platforms that support LRDIMM technology. Builders using consumer motherboards or systems requiring standard RDIMM or UDIMM modules should look elsewhere, as the Load Reduced design and quad-rank layout are not compatible with those platforms.

32GB single-module capacity for dense configurations

One module provides 32GB, allowing high total capacity when populating multiple slots in supported servers. The DDR4 2400MHz speed handles virtualisation and database workloads within the platform's rated bandwidth. Systems requiring faster memory speeds or higher frequencies than PC4-19200 will not benefit from this specific module's rated performance ceiling.

Questions about this item

What motherboard slot does this 288-pin LRDIMM require?

This module uses a DDR4 288-pin LRDIMM slot. Your server motherboard must provide that exact socket type for the memory to fit and function.

Can I mix this 4Rx4 load-reduced module with standard registered DIMMs already in my server?

No. Load-reduced and standard registered DIMMs use different electrical buffering. Mixing them in the same system will prevent the server from posting.

How do I confirm the module is running at the rated 2400 MHz after installation?

Enter the BIOS or UEFI and check the reported memory speed. It should show 2400 MHz (PC4-19200) with CL17 timings at 1.20 V.
