  • CAS latencyCL22
  • Buffer typeRegistered
  • Rated voltage1.2 V
  • 16 GB DDR4 3200 boosts server throughput
  • ECC registered design protects data integrity
  • CL22 latency at 1.2 V keeps power low
  • 288-pin 1Rx4 module fits Supermicro H12SST-PS
  • Major OEM chips tested under load for stability

Targeted server memory upgrade

This 16GB DDR4 3200 module is built for the Supermicro H12SST-PS motherboard running AMD EPYC processors. It delivers ECC registered operation at 1.2V with a CL22 latency profile for stable data integrity in critical workloads.

Suited for single-slot capacity expansion

Ideal for administrators adding memory to a validated Supermicro H12SST-PS platform where registered ECC RDIMMs are required. Not suited for consumer desktop boards that accept only unbuffered non-ECC DIMMs or systems limited to lower DDR4 speeds.

Straightforward DIMM installation

The 288-pin RDIMM seats in a standard DDR4 slot without tools or cables. Ensure the motherboard firmware is current and populate slots per the Supermicro H12SST-PS population guide; mismatched rank configurations or missing BIOS updates are the typical causes of POST failure.

Questions about this item

My Supermicro H12SST-PS board has empty DDR4 RDIMM slots — is this 288-pin module the correct form factor?

Yes — the module is a 288-pin DDR4 RDIMM, which matches the registered DIMM slots on your H12SST-PS motherboard.

Can I add this 1Rx4 registered ECC stick to existing DDR4 3200 RDIMMs that are also 1.2 V and CL22?

Provided the installed modules are also DDR4 3200 registered ECC at 1.2 V with CL22 timing, the new 1Rx4 stick will operate alongside them at the same speed and voltage.

After seating the module, how can I confirm the system recognises the full 16 GB at 3200 MT/s with ECC active?

Check the BIOS memory information or run a hardware utility — it should show 16 GB, DDR4-3200, registered ECC, 1Rx4 organisation and CL22 latency.
