NEMIX RAM
An 8 GB DDR4-3200 CL22 unbuffered UDIMM built for SuperMicro workstations and servers
This 8 GB DDR4 3200 module is built for SuperMicro workstations and servers that accept unbuffered UDIMMs. It suits administrators and technicians who need a straightforward capacity increase without ECC or registered signalling. The single-rank design keeps electrical loading low on each channel.
The stick runs at PC4-25600 with a CAS latency of 22 cycles at the standard 1.2 V. That timing is the decisive figure when matching existing memory or populating empty slots on a supported SuperMicro board. Verify the platform accepts non-ECC unbuffered UDIMMs before ordering.
Every module is stress-tested under continuous load before it ships, so it maintains rated speed and latency during long compute jobs or virtualization workloads. The 1Rx8 organisation and major-brand DRAM chips help deliver consistent throughput without thermal throttling in typical server chassis airflow.

The module runs at DDR4 3200 (PC4-25600) with CL22 latency at 1.20 V, giving the rated throughput when the platform enables that speed.
As an unbuffered 288-pin DDR4 UDIMM it connects directly to the memory controller, so maximum bandwidth is capped by the DDR4 3200 JEDEC specification.
It requires a standard 288-pin DDR4 DIMM slot and has no heat spreader, so it fits in tight server or workstation chassis without extra height.
