Computer Memory Solutions CM10246412800DIMM 8GB DDR3 1600MHz HP/Compaq Prodesk 400 G1 SFF/MT memory upgrade

HP ProDesk 400 G1 memory upgrade

This 8 GB DDR3 module is built for HP and Compaq ProDesk 400 G1 small-form-factor and mini-tower desktops. It adds a single 240-pin DIMM to systems that currently run with less memory. The kit targets owners who want a straightforward capacity increase without changing platform.

DDR3 1600 bus limited to 1066 MHz

HP documentation states the memory bus runs at 1066 MHz even when 1333 or 1600 MHz modules are installed. The module operates at 1.5 V with CL11 timing and is non-ECC unbuffered. Dual-channel benefit requires matched pairs in both sockets. A 64-bit operating system is needed to address the full 16 GB maximum.

Single DIMM installs in one slot

The board has two sockets and modules may be added one at a time, though like pairs enable dual-channel mode. If 4 GB is already present the recognised total may drop to 3.5 GB or less depending on allocation. No heat spreader is fitted so clearance is minimal. Buyers who want more than 16 GB total cannot use this platform.
