512MB DDR 333 ECC Registered Module

This 512MB DDR 333 (PC 2700) module uses 184-pin SDRAM with ECC and registered buffering. It runs at CL2.5 latency and 2.50V for server platforms that require registered memory. The stick has no heat spreader. It suits maintenance or expansion of legacy DDR systems.

Upgrade From Single-Channel Or Non-ECC DDR

Replacing a single unbuffered DIMM with this registered module adds error correction and signal integrity for multi-DIMM configurations. The jump is worth it when the motherboard chipset demands registered memory and will not post with unbuffered sticks. It does not suit boards that only accept unbuffered DDR or that require higher densities per slot.

Fits Legacy 184-Pin DDR Server Boards

The module slots into 184-pin DDR sockets that support PC 2700 registered ECC memory. It frees a slot for additional registered DIMMs up to the board's population limits. It requires a server chipset that enables registered buffering and ECC; consumer desktop boards typically disable both features.

Questions about this item

Will this 184-pin DDR module fit my server's DIMM slots?

The module uses the standard 184-pin DDR SDRAM form factor, so it fits any server board with 184-pin DDR slots keyed for 2.5 V operation.

What is the correct way to install this registered ECC stick, and what step is often missed?

Align the notch with the slot key, press firmly until both retaining clips click, and ensure the registered buffer is supported by the motherboard chipset — skipping the chipset check is the common error.

When will this 512 MB PC2700 module need replacement in a production server?

Replace it if memory diagnostics report correctable ECC errors rising over time, or when a platform upgrade requires faster than DDR 333 speeds.
