Target System Upgrade

This 4GB DDR3 module is built for HP ProDesk 400 G1 SFF and MT desktops. It delivers a straightforward memory increase for office workloads and general multitasking on those specific platforms.

Ideal for Matched Pair Builds

The kit suits owners adding a single stick to reach the 16GB maximum across two slots. Buyers needing ECC error correction or registered buffering should look elsewhere because this module is unbuffered non-ECC.

Dual Channel Pairing Requirement

HP documentation states modules must be added in like pairs to enable dual-channel operation. Installing a single 4GB stick may limit recognised memory to 3.5GB depending on system configuration.

Questions about this item

Is the 4 GB single module the only capacity option for this ProDesk 400 G1 upgrade?

The product is a single 4 GB DDR3-1600 module; the system board has two sockets and supports paired modules for dual-channel operation.

Will the memory actually run at 1600 MHz once installed in the ProDesk 400 G1?

HP documentation states the memory bus runs at 1066 MHz, so the module will operate at that lower speed in this system.

Does the 240-pin DDR3 interface limit the usable speed to 1066 MHz on this platform?

Yes, the ProDesk 400 G1 memory bus is specified at 1066 MHz, capping the effective data rate regardless of the module’s 1600 MHz rating.
