Supermicro Certified 8GB DDR4 RDIMM

This 8GB DDR4 2666MHz ECC registered DIMM is built for Supermicro servers and workstations that require registered memory with error correction. It suits administrators expanding capacity in compatible platforms where stability matters more than raw bandwidth.

Verify DDR4 RDIMM support and slot count

Confirm the motherboard accepts DDR4 registered ECC modules at 2666MHz with a 1Rx8 organisation and 288-pin RDIMM form factor. Check the qualified vendor list for the MEM-DR480L-HL02-ER26 part number and ensure the BIOS revision supports this capacity per slot.

Replaces non-ECC or slower registered modules

The jump is worth it when moving from unbuffered non-ECC memory or from lower-speed registered DIMMs that limit throughput. It also fits upgrades where the platform demands Supermicro certification for validated compatibility.

Questions about this item

Does the module arrive as a single 8 GB stick or do I need to buy anything else to reach that capacity?

The module is a single 8 GB DDR4 2666 MHz RDIMM, so the full capacity is already in the box; no extra sticks are required.

How do I choose between the Supermicro MEM-DR480L-HL02-ER26 and the Hynix HMA81GR7AFR8N-VK part numbers?

Both numbers refer to the same 8 GB 1Rx8 ECC Registered DDR4 2666 module; pick whichever part number matches your server's qualified-vendor list.

What does the 2666 MHz speed mean once the DIMM is installed in a compatible system?

The memory will run at up to 2666 MT/s (PC4-21300) with CL19 latency at the standard 1.2 V, delivering the rated bandwidth for supported platforms.
