Compatible HP ProDesk upgrade

This 8GB DDR4 module is built for HP ProDesk 400 G3 SFF, 400 G3 Tower, 490 G3, 600 G2 SFF and 600 G2 Tower systems. It targets owners of those desktops who need a straightforward capacity increase without configuration changes. The unbuffered, non-ECC design matches the original factory specification for these platforms.

Sustained-load behaviour

Rated at 2133MHz with CL15 latency and 1.2V operation, the module delivers steady throughput during long work sessions. JEDEC compliance ensures timing and voltage remain stable when the system runs continuously under multi-tasking loads. The 2Rx8 organisation supports consistent bandwidth without throttling.

Installation experience

The 288-pin UDIMM form factor drops into the standard desktop DIMM slots on the listed ProDesk models. No heat spreader means the module fits tight SFF chassis without clearance issues. The most common mistake is mixing this stick with existing modules of different speed or rank, which can prevent the system from posting.

Soalan tentang produk ini

How much heat does the 1.2V DDR4 2133MHz module add when running all day?

At 1.2V the stick draws minimal power, so it adds very little heat inside an HP ProDesk 400 G3 or 600 G2 chassis during continuous use.

Does my HP ProDesk 400 G3 Tower already have a free 288-pin DDR4 slot for this 8GB UDIMM?

The module fits any empty 288-pin DDR4 slot in the listed HP ProDesk 400 G3, 490 G3 and 600 G2 systems.

Will this CL15 DDR4 2133MHz stick run stably alongside the original memory in a ProDesk 600 G2 SFF?

Yes — it meets JEDEC DDR4 2133 CL15 specs, so it will down-clock to match existing modules and run without errors.
