Targeted server upgrade

This 128 GB kit delivers two 64 GB DDR5 4800 RDIMM modules built for the Thinkmate VSX-R5-760RTP7 workstation. Registered ECC operation and a 1.1 V supply protect data integrity in mission-critical environments. The dual-rank 2Rx4 organisation suits high-density memory channels.

Sustained workload stability

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC correction handles single-bit errors without halting the system. Samsung, Micron or Hynix DRAM chips are stress-tested under load before shipment. The CL40 timing remains consistent across extended compute sessions.

Registered ECC requirement

Only platforms that accept 288-pin DDR5 RDIMM modules with ECC can use this kit. Consumer boards and unbuffered DIMM slots are physically and electrically incompatible. Verify the workstation manual before purchase.

Questions about this item

How much heat does the 1.1V DDR5 4800 kit generate during sustained server workloads?

The modules run at 1.1V with no heat spreader, so thermal output stays low; the registered design and ECC logic add minimal overhead in a properly cooled chassis.

What motherboard feature must the Thinkmate VSX-R5-760RTP7 provide for these 288-pin RDIMMs to function?

The board must support DDR5 registered ECC memory with 2Rx4 organisation and a 1.1V supply, which the VSX-R5-760RTP7 platform provides natively.

Can the 2x64GB CL40 kit operate mixed with any existing DDR5 RDIMMs of different capacity or rank?

Mixing is possible only if the other modules are also DDR5 4800 ECC RDIMMs at 1.1V; the memory controller will train all slots to the lowest common speed and timing.
