Learn more about Supermicro SuperStorage 1U 5018D4-AR12L memory

What Supermicro SuperStorage 1U 5018D4-AR12L DIMM type is supported?

RDIMM and UDIMM

Why are there various DIMM types supported?

Factory configured 5018D4-AR12L systems often have smaller, less expensive modules. As more memory is required different density and technologies are needed. DIMM type mixing is never recommended.

What is a registered memory module?

Registered DIMM memory modules have a register component between the DRAM modules and the motherboard memory controller. When manufactured as a dual in-line memory module (DIMM), a registered memory module is called an RDIMM.

What is an unbuffered memory module?

Unbuffered, non-registered DIMM memory modules have no buffer/register component between the DRAM modules and the motherboard memory controller.

What Supermicro SuperStorage 1U 5018D4-AR12L memory speed is supported?

DDR4-2133, DDR4-2400, DDR4-2666 and DDR4-2933

Why may there be various speeds of Supermicro SuperStorage 1U 5018D4-AR12L memory?

Some servers often have various configurations and versions. If you are unsure what you need, please refer to your 5018D4-AR12L manual or data sheet. If you need tech support, please contact us.

General DIMM population guideline for Supermicro SuperStorage 1U 5018D4-AR12L upgrade to consider.

Some may or may not apply.

• Do not mix DIMM RDIMM and UDIMM types.
• If mixing memory speeds, all 4 DIMMs run at the lowest DDR4-2133 bus frequency.
• Install DIMMs starting furthest from the processor.
• Do not install DIMMs if the corresponding processor is not installed.
• If only one processor is installed in a two CPU system, only half of the DIMM slots are available.
• To maximize performance, balance the total memory capacity between all installed processors.
• It is not required, but it is recommended to load the channels similarly if possible.
