Capacity and Compatibility

This 256GB kit contains four 64GB DDR4 modules built for the Tyan Transport HX TS75A-B8252 server platform. The registered ECC design targets administrators who need maximum registered capacity on a qualified motherboard.

Registered DDR4 Interface Limits

Registered DDR4 at 3200MHz with CL22 timing requires a motherboard chipset and BIOS that support 4Rx4 organisation and PC4-25600 data rates. Systems limited to lower ranks or unbuffered memory cannot use these modules.

Build and Connector Practicalities

Each 288-pin RDIMM operates at 1.20V without a heat spreader, relying on server chassis airflow for cooling. The four-module kit fills four DIMM slots and must be installed in the exact population order specified by the Tyan manual.

Questions about this item

Should I choose the 256GB kit with four 64GB modules or a different capacity for my Tyan Transport HX TS75A-B8252?

The 256GB kit provides four 64GB RDIMMs. This matches the board's supported 4Rx4 rank structure and fills all slots for maximum capacity.

What does the 3200MHz rating deliver once installed in the server?

The modules run at DDR4 3200 (PC4-25600) with CL22 latency at 1.2V. Registered ECC operation ensures data integrity under sustained server workloads.

How does the 288-pin RDIMM interface limit performance or compatibility?

The 288-pin RDIMM form factor fits only DDR4 registered DIMM slots. It cannot be used in unbuffered UDIMM or DDR5 sockets.
