4GB DDR3 1600 UDIMM for HP EliteDesk

This 4GB DDR3 1600 CL11 module upgrades HP EliteDesk 705 G2 Tower and 800 G1 SFF or Tower systems. It uses a 240-pin unbuffered non-ECC design that matches the factory specifications for these desktops. The single 1Rx8 rank installs in any available DIMM slot without configuration changes.

JEDEC standard 1.5V operation

The module runs at the standard 1.5V DDR3 voltage defined by JEDEC, so the system memory controller draws no extra power. Passive operation with no heat spreader keeps acoustics identical to the original equipment. Power consumption stays within the platform's normal memory budget during typical workloads.

Replaces slower or smaller DDR3 DIMMs

Swapping out lower-capacity or slower DDR3 sticks adds headroom for multitasking and larger files. The upgrade is worthwhile when the current configuration leaves free slots or uses modules below 1600 speed. Systems already filled with matching 1600 CL11 modules will not see further benefit from this part.

Questions about this item

How do I install the 240-pin DDR3 DIMM in my HP EliteDesk 800 G1 SFF, and which step is often missed?

Power off and unplug the PC, open the case, align the notch on the 240-pin module with the slot key, press firmly until both retention clips snap shut, then verify the module sits evenly before closing the case.

What maintenance or replacement will this 4GB DDR3 1600 CL11 module need over its lifetime?

No routine maintenance is required; if errors appear in memory diagnostics or the system becomes unstable, replace the module — it carries a limited lifetime warranty from OWC.

What limit appears first when this 1.5V DDR3 1600 module runs under sustained heavy load?

The CL11 latency at 1600 MHz sets the throughput ceiling; thermal throttling is unlikely on an unbuffered UDIMM without a heat spreader in a ventilated EliteDesk chassis.
