System-specific DDR2 kit

This 8 GB kit contains two 4 GB DDR2-667 fully buffered ECC modules built for IBM systems. It targets administrators maintaining legacy servers that require registered memory with error correction.

Fully buffered ECC DDR2-667

The modules run at PC2-5300 speed with CL5 latency at 1.80 V and use a 240-pin interface. Fully buffered architecture and quad-rank organisation are mandatory for the compatible IBM platforms listed by the manufacturer.

8 GB total capacity

The dual-module kit provides 8 GB of registered ECC memory for supported IBM servers. Systems needing larger memory configurations or non-ECC unbuffered DDR2 cannot use this kit.

Questions about this item

What does the DDR2 667 speed rating deliver once installed in a compatible IBM system?

The modules run at 667 MT/s with CL5 latency, providing PC2-5300 bandwidth for the memory controller in supported IBM servers.

How does the fully buffered DDR2 interface affect usable performance?

Fully buffered architecture adds a serial link between the memory controller and each DIMM, enabling higher capacities but introducing extra latency versus standard registered DDR2.

What physical slot and keying do these 240-pin modules require?

They fit 240-pin DDR2 DIMM sockets keyed for fully buffered modules; standard registered or unbuffered DDR2 slots are not electrically compatible.
