Server Memory for Intel Platforms

This 4 GB DDR2 module targets administrators maintaining legacy Intel SR1500AL or SR1500ALSAS servers. Fully Buffered architecture with ECC protects data integrity in multi-socket environments where uptime is critical. The 240-pin form factor fits the specific DIMM slots used by these platforms.

Upgrade Path from Unbuffered DDR2

Replaces non-ECC or registered DDR2 modules that lack the advanced memory buffer required by the chipset. The jump is worth it when the server BIOS reports memory errors or the workload demands the signal integrity of Fully Buffered technology. Dual Rank organisation increases density per slot without changing the memory controller configuration.

DDR2 667 Interface Constraints

The PC2 5300 standard caps throughput at the rated 667 MT/s with CL5 latency at 1.80 V. No higher DDR2 speeds or later DDR generations are electrically compatible with this slot. Capacity is limited to the module's 4 GB per DIMM and the maximum rank count the memory controller supports.

Questions about this item

Will this 240-pin DDR2 module fit my server board?

Yes — it uses the standard 240-pin DDR2 form factor, so it fits any slot keyed for DDR2 667.

Do I need to enable ECC in the BIOS after installing this fully buffered stick?

Install the module, then enter BIOS and set the memory mode to ECC or Fully Buffered; skipping that step leaves error correction inactive.

How long before the heat spreader needs cleaning or replacement?

The spreader is passive and maintenance-free; only remove dust with compressed air during routine server cleaning.
