OWC 4GB DDR3 1600 CL11 204-pin SODIMM for HP Envy TouchSmart 23

HP Envy TouchSmart 23 DDR3 upgrade

This 4 GB DDR3 1600 SODIMM is built specifically for the HP Envy TouchSmart 23 series. It delivers a single unbuffered 1Rx8 module that installs directly into the 204-pin slot. The 1.5 V non-ECC design matches the original factory specification for a warranty-safe improvement.

DDR3 1600 SODIMM interface limits

The PC3-12800 CL11 rating sets the maximum bandwidth and latency for this generation of memory. DDR3 architecture caps transfer rates at 1600 MT/s and requires 1.5 V operation, so newer platforms using different voltages or keying will not accept this module. Systems already running at the chipset ceiling will not gain extra speed from this part.

Replacing factory DDR3 in the Envy 23

Swapping the original memory for this 4 GB stick raises total capacity when the board has a free slot or supports a larger single module. The jump is worth it if the current configuration leaves headroom for more RAM and the workload demands extra space for multitasking. Buyers whose TouchSmart 23 already uses the maximum supported density or runs a different memory generation will not benefit.
