Lenovo SR680a V3 768GB DDR5 kit

This 768GB kit delivers eight 96GB DDR5 5600 registered ECC modules built for the Lenovo ThinkSystem SR680a V3 rack server. It targets administrators who need maximum memory density in a validated configuration.

CL46 2Rx4 registered ECC specification

Each module runs at 5600 MT/s with CL46 latency, 2Rx4 organisation and 1.10V operation. The registered ECC design provides error correction and signal buffering required by the platform.

Eight 288-pin RDIMMs populate all channels

The 288-pin RDIMM form factor fits the server's memory slots directly. Eight modules fill the available channels, freeing no additional slots but delivering the full 768GB capacity in a single kit.

Questions about this item

What does the 5600 MT/s rating mean once the modules are installed in the Lenovo ThinkSystem SR680a V3?

The memory will run at up to 5600 MT/s, delivering PC5-44800 bandwidth for the server workloads the SR680a V3 handles.

How does the DDR5 RDIMM interface and CL46 latency affect real-world throughput?

Registered DDR5 with CL46 timing provides error-corrected data transfer at the rated 5600 speed, capped by the platform's memory controller.

Will the 288-pin 2Rx4 modules fit the SR680a V3 memory slots without a heat spreader?

Yes, the 288-pin DDR5 RDIMM form factor matches the server's DIMM slots and the low-profile design clears standard heatsinks.
