128GB DDR5 5600 EC8 RDIMM

This 128GB DDR5 5600 EC8 RDIMM module delivers 128GB capacity at 5600 MHz with CL46 latency. It operates at 1.1V using 288-pin DDR5 SDRAM technology. ECC registered design with 2S2Rx4 quad-rank 3DS/TSV organisation targets server and workstation platforms requiring high-density error-correcting memory.

Suitable systems and limits

Suits DDR5 servers and workstations that accept 128GB EC8 registered DIMMs with 2S2Rx4 rank structure. Not for desktop or laptop computers, which cannot use registered ECC modules. Builders needing non-ECC unbuffered memory or lower-capacity sticks should look elsewhere. Verify platform qualified-vendor lists before purchasing.

Deciding specification: 2S2Rx4 3DS/TSV rank

The 2S2Rx4 (4Rx4) 3DS/TSV rank configuration is the single specification that determines compatibility. Only systems qualified for this exact quad-rank x4 3DS organisation will recognise the full 128GB capacity. Match this rank string against your motherboard or OEM memory-support list to confirm fit.

商品問答

Can I add this 128GB DDR5 5600 EC8 RDIMM to a server that already has DDR5 4800 registered modules installed?

The module runs at DDR5 5600 with CL46 latency and 1.10V; mixing speeds will force all channels to the slowest module's rate and may require manual BIOS configuration for stability.

How can I verify the 2S2Rx4 quad-rank 3DS module is recognised correctly after installation?

Check the system BIOS or UEFI memory information screen — it should report a single 128GB DDR5 5600 registered ECC DIMM with 4Rx4 organisation and EC8 error-correction active.

Does the package contain only the 288-pin RDIMM or are heat spreaders and cables included?

The box contains the single 128GB DDR5 5600 EC8 RDIMM module only; no heat spreader, cables or additional accessories are supplied.
