128GB Registered DDR4 Kit for Intel Servers

This 128GB kit contains four 32GB DDR4-2400 registered ECC DIMMs built for Intel Server boards S2600BP, S2600CW, S2600ST, S2600TP and S2600WF. Each module runs at 1.2V with CL17 timing and a 2Rx4 organisation. It targets administrators expanding memory in compatible rack or pedestal servers.

Sustained Load Behaviour

Registered buffering reduces electrical load on the memory controller, allowing all 16 DIMM slots per dual-CPU system to stay populated without signal degradation. ECC corrects single-bit errors in real time, preventing data corruption during continuous workloads. The modules will clock down automatically to match the installed processor’s supported speed.

288-Pin DDR4 Registered ECC Form Factor Decides Fit

Only systems that accept 288-pin DDR4 registered ECC DIMMs can use this kit; desktop boards and laptops require unbuffered non-ECC memory and will not post. Maximum supported capacity reaches 512GB with RDIMMs or 1TB with LRDIMMs across 16 sockets. Mixing registered and load-reduced modules is not supported.

Questions about this item

Does the 1.2V DDR4 2400 kit run hot or draw extra power when the server runs 24/7?

The modules operate at 1.2V with no heat spreader, so they rely on chassis airflow; registered ECC DIMMs at this voltage add minimal thermal load in a properly cooled Intel S2600 chassis.

My Intel S2600BP board has 16 DIMM slots across two CPUs — must I fill all slots for this 4×32GB kit to work?

No, the kit works in any valid population order; install the four DIMMs in the slots recommended by the board manual for your CPU count and the system will recognise the 128GB.

Can I mix these 2Rx4 registered DIMMs with older 1Rx4 or LRDIMM modules already in the S2600WF?

Mixing ranks is usually allowed if the platform rules are followed, but mixing registered and load-reduced DIMMs is explicitly not supported on these Intel S2600 platforms.
