512GB DDR5 4800 ECC RDIMM Kit

This 512GB memory kit contains four 128GB DDR5 4800 registered DIMMs built for Thinkmate GPX-WS-740RTP7 workstations. ECC and registered operation protect data integrity in mission-critical workloads. The modules run at 1.1V with CL40 latency.

Registered 4Rx4 288-Pin Compatibility

The single specification that decides fit is the registered 4Rx4 288-pin DDR5 RDIMM form factor combined with Thinkmate GPX-WS-740RTP7 validation. Systems requiring unbuffered UDIMMs or a different rank configuration cannot use this kit. Buyers who need non-ECC memory or a different pin count must select another part.

Four-Module Kit Simplifies Population

The package delivers four matched 128GB modules in a single kit, allowing immediate full-channel population on compatible boards. No additional cables, software licences or heat spreaders are included. Installers who prefer individual modules or a different capacity per slot must source them separately.
