Server-grade capacity

This 256 GB kit delivers two 128 GB DDR5 RDIMMs running at 4800 MT/s with CL40 latency and 1.1 V operation. Registered ECC circuitry and 4Rx4 organisation provide error correction and signal integrity for mission-critical workloads.

Built for validated platforms

The modules are qualified for Thinkmate Supermicro SuperServer 511E-WR and 521E-WR systems. Builders targeting other motherboards or consumer desktop chipsets should verify qualified-vendor lists before purchasing.

Registered ECC integration

Each 288-pin DIMM plugs directly into DDR5 RDIMM slots on compatible server boards. The registered buffer reduces electrical load on the memory controller, freeing signal margin for dense population.

Questions about this item

Does my THINKMATE SuperServer 511E-WR or 521E-WR need a specific BIOS revision to recognise the 256 GB DDR5 4800 kit?

The kit is validated for the THINKMATE SuperServer 511E-WR and 521E-WR; consult the server manual for any required BIOS update before installation.

Can I mix these 128 GB 4Rx4 ECC RDIMMs with smaller DDR5 RDIMMs already installed in the same server?

Mixing different capacities or ranks is not recommended; populate all channels with identical 128 GB 4Rx4 modules for stable operation.

How do I confirm the memory is running at DDR5 4800 with ECC active after installation?

Check the server BIOS or operating system memory report — it should show 4800 MT/s, CL40 timing, 1.1 V and ECC enabled for each 128 GB module.
