NEMIX RAM
256GB kit of four 64GB DDR4 3200 ECC registered DIMMs at CL22 and 1.2V for Tyan Transport CX GC68-B8036-LE servers
This NEMIX RAM kit provides 256GB of DDR4 memory across four 64GB registered DIMMs. It is built for servers and workstations that require error-correcting code and registered buffering for stability. The modules operate at 1.2V with a CAS latency of CL22. IT professionals managing mission-critical environments will find this configuration suitable.
Each module uses a 4Rx4 organisation and runs at DDR4 3200 (PC4-25600). The registered design places a buffer on the command and address lines to reduce electrical load on the memory controller. ECC capability detects and corrects single-bit errors in real time. This specification determines whether the kit matches the motherboard's qualified vendor list.
All modules are rigorously stress tested under load to ensure reliability during continuous operation. The registered architecture maintains signal integrity when all four slots are populated at the rated speed. Error correction continues to function without interruption during extended compute tasks. The 1.2V operating voltage supports consistent thermal characteristics over long periods.

The kit runs at 3200 MT/s with CL22 latency, delivering PC4-25600 bandwidth across all four modules when the server board trains them at that rate.
The 288-pin registered DIMM slot accepts only DDR4 ECC RDIMM modules, so the kit cannot be used in UDIMM, SO-DIMM or DDR5 sockets.
Each 64 GB module is a standard-height 288-pin RDIMM with no heat spreader, so it fits any Tyan server board that supports 4Rx4 registered DIMMs.
