Quick Verdict
This 4GB DDR2 ECC Fully Buffered DIMM is a specialist server and workstation memory module for buyers who need the correct FBDIMM format rather than standard PC RAM.
What This Product Is Used For
This 4GB DDR2 ECC Fully Buffered DIMM is memory RAM designed for compatible servers, workstations and motherboards that require 240 PIN DDR2 ECC FBDIMM modules. It is available in PC2 4200 533MHz, PC2 5300 667MHz and PC2 6400 800MHz versions, with each speed supplied as a separate module option.
Compared with standard desktop DDR2 RAM, this is not intended for normal PCs because it uses ECC Fully Buffered DIMM technology. Users choose it over simpler desktop memory when their server or workstation specifically requires 240 PIN DDR2 ECC FBDIMM memory.
Who This Product Is Best Suited To
This memory is best suited to users maintaining or repairing compatible older servers, workstations or specialist motherboards.
It suits buyers who already know their system requires DDR2 ECC Fully Buffered DIMM memory and want a replacement or capacity upgrade that matches the correct server memory standard.

Pros and Cons
Pros
• Useful replacement memory for compatible servers and workstations
• ECC Fully Buffered DIMM format matches specialist motherboard requirements
• Multiple speed options help buyers select the correct module type
Cons
• Not suitable for standard PCs
• Buyers must choose the correct speed and confirm FBDIMM compatibility before purchase
Real World Performance and Day to Day Use
In real world use, this 4GB DDR2 ECC Fully Buffered DIMM is intended for systems that specifically require 240 PIN DDR2 ECC FBDIMM memory. It is listed as compatible with servers, workstations and motherboards, and it uses 1.8V power with CL4 or CL5 latency depending on the module version.
The main buyer concern is compatibility. This is not ordinary desktop RAM, and it is not for PCs. The speed options are PC2 4200 533MHz, PC2 5300 667MHz and PC2 6400 800MHz, supplied as three separate module options, so buyers need to select the version that matches their system.
Choose this if your server or workstation motherboard specifically supports 240 PIN DDR2 ECC Fully Buffered DIMM memory.
Skip this if you need standard desktop DDR2 RAM, laptop memory, DDR3, DDR4 or DDR5 memory.
Why We Like This Product
The YPC.co.uk Team likes this because it clearly serves a specialist server and workstation need rather than pretending to be general PC memory. It helps buyers avoid the mistake of fitting standard desktop RAM into a system that requires FBDIMM, and it reduces regret by making the not for PCs limitation obvious.
