System-specific DDR3 kit

This 8 GB kit contains two 4 GB DDR3 1600 CL11 modules built for the HP Compaq Pro 6305 small-form-factor business PC. The unbuffered non-ECC DIMMs use major-brand chips and run at 1.5 V without heat spreaders.

Thermals and power

Standard 1.5 V DDR3 voltage keeps power draw modest in the compact chassis. Passive operation means no fan noise, and the low-profile sticks fit the restricted airflow of the small-form-factor case without blocking other components.

Chipset speed limit

The Pro 6305 chipset runs memory at 1333 MHz, so the 1600 MHz modules will operate at the lower speed. Buyers needing the full 1600 MHz data rate should choose a platform whose chipset supports it.

Questions about this item

How do I install the 240-pin DDR3 modules into the HP Compaq Pro 6305 SFF, and what step is often missed?

Power off and unplug the PC, open the case, align the notch on each module with the slot key, press firmly until both retention clips click shut, then verify in BIOS that all 8 GB are detected at 1333 MHz.

What maintenance or replacement will the CM5126412800DIMM kit need over its lifetime?

No scheduled maintenance is required; keep the interior dust-free and ensure case airflow stays clear. If a stick fails, the limited lifetime warranty from Computer Memory Solutions covers exchange or repair against manufacturing defects.

What limit appears first when the system runs sustained workloads with this memory?

The chipset caps the memory bus at 1333 MHz even though the modules are rated for 1600 MHz, so bandwidth tops out at the lower speed before thermal or voltage limits become a factor.
