DDR4 3200 ECC registered DIMM kit adds 256 GB in two 128 GB modules for the Tyan Transport CX GC68A-B8036-LE
This 256 GB kit contains two 128 GB DDR4 3200 registered DIMMs built for the Tyan Transport CX GC68A-B8036-LE server. Each module runs at 1.2 V with CL22 latency and uses a 4Rx4 organisation. The ECC registered design targets administrators who need maximum capacity in a validated configuration.
The package supplies both 128 GB sticks together so the platform can reach 256 GB in a single upgrade step. Pre-matched modules remove the risk of mixing ranks or vendors, and the registered buffer helps the memory controller drive the heavy electrical load. No heat spreaders are fitted, so airflow in dense chassis is unimpeded.
The DDR4 3200 interface caps per-module bandwidth at PC4-25600, and the registered architecture adds one clock cycle of command latency. Four-rank density limits the number of modules a single channel can support, so total system capacity depends on the motherboard slot count and memory-controller qualification. Mixed-rank populations may force lower speeds.

The modules use major OEM Samsung, Micron or Hynix chips and are rigorously stress tested under load; no firmware updates are required and the lifetime replacement warranty covers any defect that appears during service.
The 1.20 V DDR4 RDIMMs operate at standard JEDEC voltage with CL22 latency; sustained loads are limited by the motherboard DIMM-slot airflow rather than the memory itself.
Each 288-pin DDR4 RDIMM runs at 1.20 V, so the pair draws only the nominal DDR4 registered power budget without additional heat spreaders.
