Frequently Asked Questions

What type of memory is this Crucial module?

This is a 4GB DDR2 ECC Registered Low Profile DIMM (RDIMM), designed specifically for server applications.

What does "ECC" stand for and what is its benefit?

ECC stands for Error-Correcting Code, which allows the memory to detect and correct common types of internal data corruption, enhancing system stability and data integrity in servers.

What is the speed of this memory module?

This Crucial memory module operates at PC2-5300, which corresponds to a speed of 667MHz.

Is this memory suitable for a standard desktop computer?

No, as ECC Registered (RDIMM) memory, it is specifically designed for server motherboards and is not compatible with most standard desktop computers.

What does "Low Profile" refer to in the memory description?

"Low Profile" indicates that the memory module has a shorter height, allowing it to fit into servers and systems with limited physical space or restricted airflow.

What is the capacity of a single module?

Each module provides 4GB of memory.

What Buyers Say

5.0 ★★★★★1 Amazon ratings

👍 Pros

This memory module provides 4GB of DDR2 ECC Registered Low Profile RAM, ideal for compatible server systems.
ECC (Error-Correcting Code) memory helps detect and correct data corruption, enhancing system stability and reliability.
Registered (Buffered) DIMMs improve signal integrity, allowing servers to support more memory modules and higher capacities.
The low profile design of the module allows for installation in systems with limited vertical clearance.
Operating at PC2-5300 (667MHz), it offers a solid performance for systems designed to use this specific speed.

👎 Cons

DDR2 memory is an older technology, meaning this module is only compatible with systems that specifically support DDR2.
The 4GB capacity, while good for DDR2, might be considered small for modern server applications that demand significantly more memory.
PC2-5300 (667MHz) is a slower memory speed compared to more recent DDR3, DDR4, and DDR5 standards.
This is ECC Registered memory, which is specifically for servers and incompatible with most consumer desktop motherboards.
The product information focuses solely on the memory module itself, without providing broader system compatibility details or warranty length.
