Targeted 16 GB DDR3 kit for HP Compaq Pro 6305 SFF

This 16 GB kit contains two 8 GB unbuffered non-ECC DIMMs built to the DDR3 1600 PC3 12800 standard. It is designed as a direct memory upgrade for the HP Compaq Pro 6305 Small Form Factor Business PC. The modules use 240-pin DDR3 SDRAM with a CAS latency of CL11.

Sustained operation at 1333 MHz due to chipset

Although the modules are rated for 1600 MHz the compatible chipset in the target system runs memory at 1333 MHz. Under continuous load the kit will therefore operate at this lower frequency while maintaining the rated 1.5 V voltage and 11-11-11 timings. The dual-rank 2Rx8 organisation remains unchanged.

Maximum supported capacity is 32 GB across four

The HP Compaq Pro 6305 SFF supports up to 32 GB of memory in its four DIMM slots. This 16 GB kit occupies two of those slots and leaves room for further expansion. A 64-bit operating system is required to address memory above 4 GB.

Questions about this item

How much power does the 1.5 V DDR3 kit draw when the Pro 6305 runs all day?

Each module operates at 1.5 V; total draw depends on the Pro 6305 memory controller and workload, not on the kit alone.

What must the HP Compaq Pro 6305 already have for this 240-pin DDR3 upgrade to work?

The Pro 6305 needs four free 240-pin DDR3 slots and a 64-bit operating system to address the full 16 GB.

Will the 1600 MHz CL11 modules run at their rated speed alongside the Pro 6305's original 1333 MHz memory?

The chipset limits all memory to 1333 MHz, so the new CL11 sticks will downclock to match the existing 1333 MHz modules.
