SuperMicro Compatible DDR5 UDIMM

This 16GB DDR5 module is built for SuperMicro desktop and workstation platforms that accept non-ECC unbuffered memory. It targets system builders and IT professionals who need a direct replacement validated for those specific boards. The single-rank 1Rx8 organisation keeps the memory controller load light. Buyers requiring ECC protection or registered DIMMs should look elsewhere.

1.1 V 288-Pin DDR5 4800 single module

The stick plugs into a standard 288-pin DDR5 UDIMM slot and runs at the JEDEC 4800 MT/s rate with 1.10 V. No heat spreader is fitted, so airflow from the chassis fans must reach the DRAM packages directly. One module populates a single channel; adding a second identical stick enables dual-channel bandwidth if the motherboard supports it. Systems locked to lower DDR5 speeds will down-clock automatically.

CL40 latency under sustained workloads

CAS latency of 40 cycles at 4800 MT/s delivers predictable access times during long compute sessions such as rendering, compilation or database indexing. The major-brand Samsung, Micron or Hynix die selection is stress-tested under load to maintain stability without thermal throttling. Continuous operation at the rated voltage and frequency is the design target rather than short burst overclocking headroom.

Questions about this item

How does the CL40 latency affect real-world responsiveness under sustained workloads?

CL40 is the rated CAS latency at 4800 MT/s; it determines the minimum cycle delay for each column access, so sustained throughput will reflect this timing.

What thermal behaviour should I expect when the module runs continuously at 1.10 V?

The stick has no heat spreader and operates at the standard 1.10 V DDR5 voltage, so case airflow alone must dissipate the heat generated during all-day operation.

Which motherboard slot and chipset combination is required for this 288-pin UDIMM to function?

A desktop or workstation board with a DDR5-compatible 288-pin UDIMM slot and a chipset that supports non-ECC unbuffered DDR5 at 4800 MT/s is needed.
