NEMIX RAM
A 1 TB registered ECC DDR4 kit of sixteen 64 GB modules at 3200 MT/s CL22 1.2 V for Tyan TS65A-B8036 servers
This 1 TB kit contains sixteen 64 GB DDR4-3200 registered ECC RDIMMs built for the Tyan Transport SX TS65A-B8036 server. Each module runs at 1.2 V with CL22 latency and a 4Rx4 organisation. The memory is validated for mission-critical enterprise workloads that demand error correction and registered signalling.
The DDR4-3200 interface tops out at 25 600 MB/s per module, so total bandwidth scales with the number of populated channels on the host board. Registered buffering adds one clock cycle of latency but allows the platform to address all sixteen modules without signal degradation. ECC operation requires a motherboard that supports registered DIMMs and the matching RAS features.
Sixteen ranks of 64 GB each deliver 1 TB of addressable memory, suitable for large virtualisation clusters, in-memory databases and heavy simulation jobs. The 4Rx4 density means each rank is quad-rank, so the platform must support that rank depth per channel. Workloads exceeding 1 TB or needing faster than 3200 MT/s will require a different memory generation or additional sockets.

The 1TB kit contains sixteen 64GB modules running at DDR4 3200 CL22 1.2V 4Rx4 registered ECC. Choose it when the board has sixteen free DIMM slots and the workload needs maximum capacity; otherwise a smaller kit leaves room for future expansion.
DDR4 3200 transfers at 25600 MB/s peak; CL22 adds 22 cycles of latency at that frequency. In a Tyan TS65A-B8036 the registered 4Rx4 modules keep signal integrity across all sixteen slots so sustained bandwidth stays close to the rated figure.
The 288-pin RDIMM socket caps the kit at DDR4 3200 and 64GB per module; the registered buffer and 4Rx4 organisation let the memory controller address all sixteen ranks without exceeding the electrical load limit of the Tyan TS65A-B8036.
