G.SKILL G5 Series 128GB DDR5 6400 ECC Registered Kit

This G.SKILL G5 Series kit provides 128GB of DDR5 memory across four 32GB RDIMM modules. It operates at DDR5 6400 (PC5 51200) with CL32-39-39-102 timings at 1.40V. The modules feature ECC and Registered buffering for data integrity in server environments. Intel XMP 3.0 profiles simplify configuration on supported platforms.

Targeted at Intel W790 Workstation Builders

This memory suits builders assembling workstations with Intel Xeon W-2400X series processors on Intel W790 chipset motherboards that support quad-channel architecture. It is not for consumer desktop platforms lacking RDIMM support or ECC capability. Systems without four-channel memory architecture cannot utilise the full kit bandwidth. Buyers needing unbuffered UDIMMs or lower voltage operation should consider different memory types.

Quad-Channel Kit Requires W790 Motherboard

The decisive specification is the quad-channel kit design requiring an Intel W790 series chipset motherboard with four-channel memory support. Without this specific chipset and CPU combination the modules will not operate at their rated DDR5 6400 speed or utilise the full 128GB capacity across four channels. Verify motherboard QVL compatibility before purchase.

Questions sur cet article

Does the 1.40 V operating voltage become the main limit during sustained heavy workloads?

The modules run at 1.40 V to reach DDR5 6400 speeds; sustained heavy workloads will keep them at this voltage, so cooling must handle the resulting heat load.

How much noise or heat do the bare modules produce when running all day at DDR5 6400?

The kit has no heat spreader, so the DRAM and register chips rely entirely on chassis airflow; expect noticeable heat output and plan for directed cooling rather than passive dissipation.

Which motherboard chipset and CPU generation must I already own for this quad-channel kit to function?

You need an Intel W790 chipset motherboard with four-channel support and a Xeon W-2400X series processor to enable the rated XMP 3.0 profile.
