Supermicro MBD-C9Z490-PG DDR4 kit

This 16GB kit contains two 8GB DDR4 UDIMM modules validated for the Supermicro MBD-C9Z490-PG motherboard. It targets builders upgrading that specific board with matched, tested memory. Buyers needing ECC error correction or registered buffering should look elsewhere, as this kit provides neither.

Two-slot unbuffered 288-pin DDR4 upgrade

The modules install directly into standard 288-pin DDR4 DIMM slots without additional cables or power connectors. Running at 1.2V, they draw minimal power from the motherboard and leave headroom for other components. The kit occupies two slots, so systems with only two slots will reach maximum capacity with this upgrade.

Low-voltage CL21 modules without heat spreaders

Operating at DDR4 2933 with CL21 latency and 1.2V, the sticks run cool enough to forego heat spreaders in normal airflow. No moving parts means silent operation. Power draw stays low thanks to the standard DDR4 voltage, keeping thermal load modest inside the chassis.

Questions sur cet article

Will the CL21 latency become a bottleneck during sustained workloads?

CL21 is the rated CAS latency for these DDR4 2933 modules; sustained throughput is determined by the memory controller and workload profile.

How much heat do the 1.20 V modules add to a chassis running continuously?

At 1.20 V these unbuffered UDIMMs draw standard DDR4 power and have no heat spreader, so case airflow handles the thermal load.

Which motherboard slot layout is required for the 288‑pin kit to work?

The kit installs in two standard 288‑pin DDR4 DIMM slots on the Supermicro MBD‑C9Z490‑PG board.
