Axiom 4GB DDR3 1600 ECC Unbuffered DIMM

This 4GB DDR3 module runs at 1600 MHz with ECC error correction and unbuffered signal processing. It operates at 1.35 V and follows the PC3-12800 standard. The 240-pin DIMM form factor measures 157.5 mil in thickness and is designed for compatible HP ProLiant servers including the BL460c Gen8, DL120 G7, DL160 Gen8, DL320e Gen8, DL360e Gen8 and DL360p Gen8 models.

Suited for administrators maintaining listed HP

This memory suits technicians who need ECC protection and 1600 MHz speed for the specific ProLiant models named in the compatibility list. It is not for builders who need higher capacities, registered or buffered modules, different voltage requirements, or support for server platforms not included in the validated compatibility list.

4GB capacity and ECC unbuffered specification

The single specification that decides fit is the 4GB ECC unbuffered DDR3 1600 configuration at 1.35 V. Only systems qualified for this exact combination of capacity, error correction, buffering type, speed and voltage will accept the module without configuration issues.

Questions about this item

Does the 1.35 V DDR3 1600 module run cooler than standard 1.5 V DDR3 during continuous operation?

The module operates at 1.35 V, which is lower than the standard 1.5 V for DDR3, reducing power draw and heat output during all-day server workloads.

Which server models are confirmed compatible with this 240-pin DDR3 ECC unbuffered DIMM?

This memory is validated for HP ProLiant BL460c Gen8, DL120 G7, DL160 Gen8, DL320e Gen8, DL360e Gen8 and DL360p Gen8 servers.

Will this DDR3 1600 stick down-clock automatically if installed alongside slower DDR3 modules in the same system?

DDR3 memory defaults to the lowest common speed across all populated slots; the module will run at the speed of the slowest installed DIMM.
