HP Pro 6305 MT/SFF memory kit

This 4GB kit supplies two 2GB unbuffered DDR3 DIMMs built to the PC3-12800 standard. It targets owners of the listed HP business desktops who need a straightforward capacity increase. The modules run at 1.5V with CL11 timings and carry no heat spreader. Installation is a direct swap into the 240-pin slots.

Sustained-load behaviour

The JEDEC 1600MHz rating and 11-11-11 timings remain stable during extended workloads because the modules operate at the standard 1.5V without overclocking headroom. Unbuffered single-rank organisation keeps signal integrity consistent across all populated slots. Thermal output stays modest without a spreader, relying on normal chassis airflow.

Upgrade context

This kit replaces or adds to the factory memory in HP Pro 6305 MT and SFF systems identified by the supplied part numbers. The jump is worthwhile when the board currently holds less than 4GB or when empty 240-pin sockets are available. Maximum supported capacity for these models is 32GB, so further expansion remains possible after this install.

Questions about this item

How much heat and power will the 1.5 V DDR3 1600 kit draw when the Pro 6305 runs all day?

At 1.5 V the unbuffered DDR3 modules draw only modest power and produce little heat, so the Pro 6305’s standard cooling handles continuous operation without extra airflow.

What must already be present in the HP Pro 6305 MT/SFF for these 240-pin DIMMs to work?

The system needs free 240-pin DDR3 slots that accept 1.5 V unbuffered non-ECC memory; the Pro 6305 MT/SFF chassis provides up to four such sockets.

Will the CL11 1600 MHz modules run at their rated speed alongside the original memory in a Pro 6305?

The kit is guaranteed compatible with the Pro 6305 MT/SFF; when installed together the memory will operate at the highest common speed supported by the platform.
