HP ProDesk 600 G1 SFF/Tower memory upgrade

This 4 GB DDR3 module is built specifically for HP ProDesk 600 G1 Series small-form-factor and tower desktops. It installs as a single 240-pin DIMM running at 1600 MHz with CL11 timing and 1.5 V operation. The unbuffered, non-ECC design matches the factory specification for these business PCs.

Suited for owners adding capacity to a supported

Buyers who need ECC error correction, registered modules, or speeds beyond DDR3 1600 should look elsewhere. The kit contains only one 4 GB stick, so systems requiring a matched pair for dual-channel operation will need a second identical module. Maximum platform memory is 32 GB across four slots.

Sustained workload behaviour

The module operates at the standard 1.5 V without a heat spreader, relying on case airflow for cooling during extended use. HP documentation notes the memory bus runs at 1066 MHz regardless of module rating, so bandwidth under continuous load reflects that lower bus speed. Stability is maintained through the validated CL11 11-11-11 timing profile.

Questions about this item

Does this 240-Pin DDR3 module require a free DIMM slot on an HP ProDesk 600 G1 SFF or Tower motherboard?

Yes, the module fits a standard 240-Pin DDR3 DIMM slot. The ProDesk 600 G1 SFF and Tower each provide four such slots, so at least one must be empty for installation.

If I keep existing DDR3-1333 or DDR3-1066 modules, will this 1600 MHz stick run at the slower speed?

The system memory bus operates at 1066 MHz regardless of module rating. Any faster module, including this 1600 MHz part, will downclock to match the bus speed when mixed with slower modules.

How can I confirm the 4 GB module is recognised after installation?

Enter the system BIOS or open the operating system memory information screen; both should report the additional 4 GB, raising total installed memory toward the 32 GB maximum supported by the platform.
