4GB DDR2 800MHz ECC Kit

This Computer Memory Solutions kit provides 4GB of DDR2 800MHz ECC unregistered memory in a matched pair of 2GB modules. It is built for HP ProLiant DL320 G4 and DL320 G5p servers that require 240-pin DDR2 SDRAM with error-correcting code. The modules run at 1.8V with CL6 6-6-6 timing and use 2Rx8 major-brand chips.

Suited for legacy server upkeep

The kit targets administrators maintaining the listed HP ProLiant models where DDR2 ECC DIMMs are mandatory. It is not for buyers who need registered or buffered modules, higher capacities, or faster speeds. It also does not suit desktop boards that lack ECC support or accept only non-ECC memory.

Unregistered ECC DDR2 compatibility

The single deciding specification is that these are unregistered ECC DDR2 DIMMs. The target server must accept 240-pin PC2-6400 unbuffered ECC memory; registered or fully-buffered variants will not work in the same slots.

Questions about this item

Does this kit use the standard 240-pin DDR2 DIMM form factor for the DL320 G4 and G5p?

Yes, each module is a 240-pin DDR2 DIMM, the exact form factor required by the ProLiant DL320 G4 and G5p memory slots.

What is the correct slot population order when installing both 2GB sticks in a DL320 G4 or G5p?

Populate the lowest-numbered DIMM slots first, typically slots 1 and 2, so the matched pair runs in dual-channel mode.

Will the ECC function remain active for the lifetime of the modules, or does it degrade?

ECC is a hardware feature of the DRAM and does not wear out; the modules will continue to detect and correct single-bit errors as long as they operate within the rated 1.8 V specification.
