Overview

The HP 370780-001 is a 512MB PC-2700R DDR Registered ECC DIMM designed for use in HP server platforms. Operating at 333MHz with a 184-pin form factor, this module is built for environments where data integrity is non-negotiable — the ECC functionality detects and corrects single-bit errors in real time, while the registered (buffered) architecture reduces electrical loading to support stable operation in multi-DIMM configurations.

Sold as a refurbished unit, this module provides a cost-effective path for maintaining or modestly upgrading legacy HP servers that remain in production. While 512MB is minimal by today's standards, it serves an important role for organizations keeping older infrastructure running without the expense of new hardware. The HP part number ensures compatibility with systems originally specified for this module, reducing the guesswork that comes with sourcing memory for aging equipment.

Pros & Cons

👍 Pros

ECC Registered design provides data integrity and error correction critical for server environments.
Refurbished pricing makes it an affordable option for extending the life of older servers.
HP-branded module ensures compatibility with HP server systems that require this part number.
184-pin DDR form factor is a direct match for legacy server motherboards.

👎 Cons

512MB capacity is very small by modern standards, limiting its usefulness to legacy systems only.
Refurbished condition means the module has been previously used, with potentially shorter remaining lifespan.
PC-2700R (333MHz) speed is outdated and not compatible with newer DDR2/DDR3/DDR4 systems.
Single module provides minimal memory — multiple units would be needed for meaningful upgrades.

Frequently Asked Questions

What servers is the HP 370780-001 compatible with?

This is an HP-branded ECC Registered DDR DIMM (PC-2700R) designed for HP ProLiant and similar servers that accept 184-pin registered DDR memory at 333MHz.

What does ECC Registered mean for this memory module?

ECC (Error-Correcting Code) detects and corrects single-bit memory errors, while the Registered (buffered) design reduces electrical load on the memory controller, allowing servers to support more DIMMs with greater stability.

Is this module new or refurbished?

This is a refurbished unit that has been tested for functionality, offering a budget-friendly alternative to new modules.

Can I mix this with other memory speeds in my server?

It is generally not recommended to mix memory speeds. All installed DIMMs should match in speed and type for optimal performance and compatibility.
