256GB DDR4 3200 ECC RDIMM Kit

This kit provides 256GB of DDR4 3200 memory in two 128GB registered DIMMs. It is built for the Tyan Transport HX TN83-B8251 server platform. The modules carry ECC and registered buffering for data integrity in multi-socket workloads.

Sustained load behaviour with CL22 latency

Each module runs at 1.20V with a CAS latency of 22 cycles. The 4Rx4 organisation spreads accesses across four ranks per DIMM. Registered buffering reduces electrical load on the memory controller during continuous throughput.

DDR4 RDIMM interface practical limits

The 288-pin RDIMM form factor fits DDR4 registered slots only. ECC and registered signalling are required by the target platform. Systems without registered memory support cannot use these modules.

Questions about this item

How much power does the 1.2 V DDR4 3200 RDIMM kit draw when the Tyan TN83-B8251 runs continuously?

Each module operates at 1.20 V; total system power depends on the platform's memory controller and workload, not on the kit alone.

What must the Tyan Transport HX TN83-B8251 already support to accept this 256 GB (2 x 128 GB) 4Rx4 registered ECC kit?

The board needs DDR4 RDIMM slots that accept 288-pin 4Rx4 modules at 3200 MT/s with ECC and registered buffering.

Can the CL22 3200 MT/s kit run alongside slower DDR4 RDIMMs already installed in the TN83-B8251?

Mixed speeds are not guaranteed; the motherboard will typically clock all modules to the slowest installed speed and loosest timings.
