HP Pro desktop upgrade

This 8 GB kit supplies two 4 GB unbuffered DDR3 DIMMs rated at 1333 MHz with CL9 timing and 1.5 V operation. It is built to match the slot count and voltage of HP Pro 3115, 3125, 3130, 3135, 3300, 3400 and 3405 systems.

Suited for listed HP Pro towers

The modules are validated for the exact models named in the compatibility list, so owners of those desktops can install them without configuration changes. Buyers with other HP lines, non-HP motherboards, or a need for ECC or registered memory will not be served by this kit.

1333 MHz DDR3 speed grade

The PC3 10600 rating determines whether the memory matches the bus speed the platform expects; if the board requires a different DDR3 frequency or a newer memory generation, this kit will not function.

Questions about this item

Will the 240-pin DDR3 modules need any firmware updates or re-seating after long-term use?

No firmware is involved; the modules are unbuffered non-ECC DIMMs that simply plug into the 240-pin slots and run at 1.5 V.

What limit appears first when the kit runs continuously at 1333 MHz in a Pro 3400?

The system caps usable memory at 16 GB with a 64-bit OS, so the 8 GB kit leaves headroom before that ceiling is reached.

How much extra heat or fan noise do the 2Rx8 sticks add when the Pro 3115 runs all day?

The modules have no heat spreader and operate at standard 1.5 V DDR3 voltage, so they add minimal thermal load to the existing chassis airflow.
