Supermicro Certified 64GB DDR4 Server Module

This 64GB DDR4 3200 module carries Supermicro certification and Hynix chips. It is built as a 2Rx4 registered ECC RDIMM for 288-pin server platforms. The stick runs at PC4-25600 speed with CL22 latency at standard 1.20V voltage. It targets administrators expanding memory capacity in qualified Supermicro systems.

Who this suits and who should look elsewhere

This module suits IT teams adding high-density registered ECC memory to compatible Supermicro servers. Builders needing unbuffered UDIMMs, lower capacities, or different speeds should look elsewhere. Systems that do not support registered ECC RDIMMs cannot use this product. Buyers must confirm their platform accepts 64GB 2Rx4 modules before purchase.

What the certification and testing change

Supermicro certification means the module has been validated on the vendor's qualified hardware list. A-Tech adds full quality-assurance testing on every stick to verify reliability. The result is a memory upgrade that meets the original system manufacturer's compatibility and stability requirements for production deployments.

Questions about this item

Will my server need a DDR4 3200 MHz RDIMM slot to use this 64 GB module?

Yes, this is a 288-pin DDR4 RDIMM that runs at 3200 MHz with 1.2 V, so the motherboard must provide a registered DDR4 DIMM slot.

Can I mix this 2Rx4 registered ECC stick with older single-rank unbuffered DDR4 DIMMs?

No, registered ECC modules cannot be mixed with unbuffered non-ECC DIMMs; the memory controller will not initialise a mixed configuration.

How can I confirm the module is running at 3200 MHz CL22 after installation?

Check the BIOS memory information screen or run a tool such as dmidecode to verify the reported speed is 3200 MT/s and CAS latency is 22.
