NEMIX RAM 256GB DDR4 3200 ECC RDIMM Kit

This 256GB kit contains two 128GB DDR4 3200 ECC RDIMM modules built for the Tyan Transport CX GC68A-B8036. Registered buffering and error correction keep data integrity intact during sustained server workloads. It targets administrators upgrading memory in compatible Tyan platforms.

Capacity and headroom: 256GB across two slots

Dual 128GB modules deliver 256GB total capacity while occupying only two DIMM slots. Each module runs at 3200 MT/s with CL22 latency at 1.2V. The 4Rx4 organisation provides high density per slot. Systems requiring more than 256GB or faster speeds will exceed this kit’s limits.

Build fit: 288-pin RDIMM for registered Tyan boards

The 288-pin RDIMM form factor fits registered DDR4 server motherboards that support 4Rx4 modules. No heat spreader is included, so airflow across the modules must be adequate. ECC and registered signalling reduce electrical load on the memory controller, freeing headroom for additional DIMMs if the board allows.

Questions about this item

Will the 4Rx4 organisation on these 128GB modules work alongside existing 2Rx4 DDR4 3200 ECC RDIMMs in my Tyan GC68A-B8036?

The kit uses 4Rx4 modules at DDR4 3200 with CL22 timing; mixing ranks is possible if the motherboard memory controller supports it, but you should populate identical ranks per channel for best stability.

How can I verify the 256GB kit is running at the rated 3200 MT/s with ECC active after installation?

Enter the system BIOS or UEFI and confirm the memory frequency reads 3200 MT/s, the voltage shows 1.20V, and ECC is reported as enabled for each DIMM slot.

Does the package include only the two 128GB RDIMMs or are there any extra brackets or cables?

The box contains the two 288-pin DDR4 ECC RDIMM modules totalling 256GB; no heat spreaders, brackets or cables are included.
