HP MicroServer N40L Wiki

The N40L comes with 1x2GB ECC RAM installed. It will accept up to 2×8GB (16GB total) (Gen8 will accept 32GB (2×16GB)) 240-Pin DDR3 SDRAM 1333 (PC3 10600) RAM [1]. Non-ECC RAM is compatible, but not recommended for mission critical servers. Most casual, NAS or home server systems do not require ECC RAM.[2]

The HP Microserver does not support registered (buffered) modules. Using registered modules will result in the server failing to POST/boot. ('blue light').

The N40L is capable of utilising dual channel RAM, which results in marginally increased memory speeds when two matched DIMMs are installed.[3]

Ensure that RAM modules do not have large heat-sinks protruding from the top (clearance approx. 40mm from slot to chassis).
