32 GB DDR4 3200 CL22 ECC registered RDIMM kit of four 8 GB modules for Tyan Transport CX GC68A-B8036-LE servers
This 32 GB kit provides four 8 GB DDR4 3200 ECC registered DIMMs validated for the Tyan Transport CX GC68A-B8036-LE platform. The modules operate at 1.2 V with CL22 latency and use a 1Rx8 organisation. They are built with major OEM chips from Samsung, Micron or Hynix and carry no heat spreader.
The 32 GB total capacity suits multi-socket server workloads that benefit from error correction and registered signalling. Four ranks populate the board evenly, leaving additional slots open for future expansion when the platform supports higher totals. Workloads exceeding this capacity will require higher-density modules or a board with more slots.
Each module uses the standard 288-pin DDR4 RDIMM form factor and runs at the JEDEC 1.2 V level. The registered design reduces electrical load on the memory controller, helping stability in dense configurations. No heat spreader means clearance is minimal, but airflow across the bare PCB must be provided by the chassis. Ensure the motherboard firmware supports registered ECC DIMMs before installation.

The modules operate at 3200 MT/s with CL22 latency and 1.20 V. When mixed with slower DDR4 RDIMMs the system will typically clock all channels down to the lowest common speed and tightest timing, so stability depends on the motherboard's memory controller and BIOS.
Enter the BIOS or UEFI and check the memory information screen — it should show 32 GB total, 3200 MT/s (PC4-25600), CL22, 1.20 V, registered ECC mode enabled. In the OS, tools such as dmidecode on Linux or CPU-Z on Windows will confirm speed, rank (1Rx8) and ECC status.
The package contains four 8 GB DDR4 3200 CL22 1.20 V 288-pin ECC registered DIMMs — no heat spreaders, brackets, cables or additional cooling are included or required for standard server chassis airflow.
