Target systems

This 64GB kit uses four 16GB DDR3 1600 registered ECC modules built for Supermicro SuperWorkstation 5037A and 7047A series. It suits administrators extending the life of those platforms or building replacement servers that require registered memory.

Platform constraints

Registered ECC RDIMMs operate only in workstation and server chipsets that support the registered signal buffer; they will not function in standard desktop boards. The modules cannot be mixed with unbuffered memory and require a platform qualified for DDR3 1600 at 1.5V.

Installation notes

Each 240-pin DIMM installs like any DIMM, but the registered design demands correct slot population order defined by the Supermicro manual. The most common error is placing these modules in a consumer board or mixing them with unbuffered sticks, which prevents the system from posting.

Questions about this item

Should I pick the 64GB kit or buy single 16GB modules instead?

The kit supplies four matched 16GB modules for a total of 64GB, which is the simplest way to fill four slots on a Supermicro SuperWorkstation 5037A or 7047A.

What does the 1600MHz CL11 rating deliver in a live system?

The modules run at DDR3 1600 (PC3-12800) with CL11 latency at 1.5V, giving the rated bandwidth and timing when installed in a compatible workstation.

Does the 240-pin registered ECC interface limit which boards can use it?

Yes — the 240-pin DDR3 ECC registered DIMMs are designed for workstation and server platforms such as the Supermicro SuperWorkstation 5037A and 7047A series and will not work in standard desktop boards.
