8 GB DDR4 SODIMM for Supermicro servers

This 8 GB DDR4 2666 SODIMM is built for Supermicro server and workstation platforms that accept unbuffered non-ECC memory. It targets administrators and integrators who need a straightforward capacity increase in compatible 260-pin slots. The module uses major OEM DRAM from Samsung, Micron or Hynix and runs at the standard 1.20 V. It is not suited for systems that require registered or ECC DIMMs.

Capacity and headroom

A single 8 GB rank (1Rx8) at DDR4 2666 (PC4-21300) CL19 adds usable memory for typical multi-tasking, virtualisation hosts and database workloads that fit within this footprint. Headroom ends when the working set exceeds the installed capacity or when the platform demands ECC or registered modules. The non-ECC unbuffered design limits use to boards that explicitly support this configuration.

Thermals noise and power

Without a heat spreader the module relies on chassis airflow, drawing 1.20 V at the rated speed. Power consumption stays low for DDR4 SODIMM form factors and produces no audible noise. Thermal headroom is adequate for normal server environments with proper case ventilation; sustained heavy loads in restricted airflow may require additional cooling attention.

Questions about this item

Will this DDR4 2666 CL19 SODIMM run alongside existing DDR4 2666 modules in my SuperMicro system?

Yes, matching speed and latency helps the memory controller keep all slots at 2666 MHz; mixing slower sticks would force the whole array down to the lowest common speed.

How can I verify the module is detected at 2666 MHz with CL19 timings after installation?

Check the BIOS memory information screen or run a tool such as CPU-Z; it should report DDR4-2666, 1.20 V, CAS 19 and a single 8 GB rank.

Does the package include only the 260-pin SODIMM or are any brackets or cables supplied?

The box contains one 8 GB 260-pin DDR4 SODIMM and nothing else; no brackets, cables or tools are included.
