Server memory kit

This kit provides 32 GB of DDR3 registered ECC memory in a matched set of four 8 GB modules. It is built for servers and workstations that require error correction and registered signalling for stable operation under continuous load. The modules conform to JEDEC standard specifications and are validated through Advanced Validation Labs testing.

Thermals and power

Each module operates at the standard DDR3 voltage of 1.50 V, keeping power draw predictable in densely populated memory channels. Registered buffering reduces electrical loading on the memory controller, which helps maintain signal integrity without increasing heat output. Passive cooling is sufficient for typical server chassis airflow.

Capacity and configuration

The 32 GB total capacity is delivered as a quad-channel kit of four 8 GB sticks, allowing full population of four slots on compatible platforms. Buyers who need larger individual modules or higher densities should look elsewhere. The 240-pin DDR3 form factor limits use to systems designed for that generation.

Questions about this item

How do I install the 240-Pin DDR3 registered DIMMs and what step is often missed?

Align the notch on each 240-Pin module with the slot key, press firmly until both retention clips click, and ensure the registered buffer engages by seating all four 8GB sticks in the correct channel order for your server board.

What maintenance or replacement will the ECC registered kit need over time?

The modules themselves require no scheduled maintenance; ECC corrects single-bit errors on the fly, and a stick only needs replacement if the system logs uncorrectable errors or a module fails POST testing.

What limit appears first when the 1600 CL11 1.50V kit runs under sustained load?

The DDR3 1600 JEDEC specification caps data rate at 1600 MT/s and voltage at 1.50V, so sustained throughput and thermal headroom hit that electrical ceiling before any other bottleneck.
