The OWC 4GB DDR3-1600 UDIMM is a single memory module for users upgrading a compatible HP ProDesk 400 G1 SFF, 400 G1 Tower, 400 G2 Tower, 405 G1 Tower, or 490 G1 Tower. It uses 240-pin, 1.5V, non-ECC, unbuffered memory with CL11 latency.
Recommended For
- HP ProDesk 400 G1 SFF, 400 G1 Tower, 400 G2 Tower, 405 G1 Tower, or 490 G1 Tower owners replacing a failed DIMM or matching an existing memory configuration.
- Owners of a listed ProDesk with an open compatible slot who want to add 4GB for light office work, email, and basic browsing; check the PC’s current RAM and configuration before buying.
- Refurbishers maintaining listed HP ProDesk desktops who need a standard 240-pin, non-ECC DDR3 desktop DIMM for a repair or modest memory upgrade.
Real-World Use Scenarios
- When an HP ProDesk 400 G1 feels sluggish with email, documents, and several browser tabs open, adding this module can give memory-constrained tasks more room and may reduce slowdowns when switching between them. The benefit depends on the computer’s current memory and software; it does not upgrade the processor or storage.
- For someone keeping an older ProDesk in service for routine business or home tasks—such as word processing, email, and web browsing—this 4GB module can expand available memory when installed in a compatible configuration. It is a memory upgrade, not a guarantee that newer or demanding software will run well.
- When refurbishing a compatible ProDesk for a shared, light-duty workstation, this module can add memory without replacing the desktop. Check the installed memory and system configuration first; the module can supplement existing RAM or replace a compatible stick, but the total capacity depends on what is already installed.
- If the ProDesk uses integrated graphics and has an equal-capacity memory module in the other channel, adding this 4GB stick may help create a balanced dual-channel setup. HP notes that unbalanced memory configurations can reduce graphics performance; this is a configuration-dependent benefit, not a gaming upgrade.
