Brute Networks 32GB DDR4-2666 RDIMM

This 32GB registered DDR4 module operates at 2666 MT/s with CL15 latency and 1.20V power draw. It uses a 2Rx4 organisation and includes ECC for error correction. The stick is built with major-brand DRAM and validated as a direct replacement for Lenovo part 7X77A01304.

Verify DDR4 registered DIMM support

Confirm the server accepts 288-pin registered DDR4 memory and that the memory controller can address 32GB single-rank-equivalent modules at 2666 MT/s. The platform must also support ECC and 1.20V operation. Mixed populations with unbuffered or load-reduced DIMMs are not supported by this module type.

Steady-state behaviour under load

Registered buffering and ECC maintain data integrity during continuous write-read cycles. Major-brand DRAM and 1.20V operation keep thermals stable in populated channels. The module sustains its rated 2666 MT/s throughput without down-clocking when all slots are filled in compatible Lenovo systems.

Questions about this item

Does the 32GB DDR4-2666 RDIMM arrive as a single stick or do I need to order a matching kit?

Each unit is one 288-pin registered DIMM; the supplier ships identically matching modules so multiple units stay consistent.

Should I pick the CL15 2Rx4 module or a different rank for my Lenovo server?

The 2Rx4 CL15 registered stick matches Lenovo part 7X77A01304 and is validated for those platforms.

What does the PC4-21300 rating deliver once the module is installed?

It runs at DDR4-2666 with CL15 latency at 1.20V, providing ECC error correction and registered buffering for stable server operation.
