Computer Memory Solutions CM20486417000SO 32GB (2x16GB) DDR4 2133MHz CL15 SODIMM for HP ZBook 15u G4

SKU CH-S817-TPSAF

A 32 GB dual-channel DDR4 SODIMM kit running at 2133 MHz with CL15 timing, validated for the HP ZBook 15u G4 mobile workstation

  • Capacity32GB (2 x 16GB)
  • Type260-Pin DDR4 SO-DIMM
  • SpeedDDR4 2133 (PC4 17000)
  • CAS LatencyCL15
  • Timing15-15-15
  • Voltage1.2V
  • Guaranteed compatibility with HP ZBook 15u G4 workstations
  • 32 GB total capacity in a matched 2 x 16 GB kit
  • DDR4 2133 MHz speed for responsive multitasking
  • Low 1.2 V operation reduces power draw and heat
  • CL15 CAS latency with 15-15-15 timing for quick data access

Targeted Upgrade Kit

This 32 GB kit delivers two 16 GB DDR4 SO-DIMM modules built for the HP ZBook 15u G4 mobile workstation. It matches the factory speed of 2133 MHz and CL15 timing so the system recognises the memory without configuration changes. The unbuffered, non-ECC design fits the laptop's two available slots and reaches the platform maximum of 32 GB.

Cool Silent Operation

Each module runs at the standard DDR4 voltage of 1.2 V and has no heat spreader, relying on the notebook's existing airflow. Passive operation adds no fan noise and draws minimal power, leaving thermals and battery life unchanged during typical workloads. The low-profile 260-pin form factor seats cleanly beneath the service cover.

Deciding Specification

The kit is validated for the ZBook 15u G4 part numbers 1BS31UT, 1BS33UT and 1BS34UT, which support a maximum of 32 GB across two sockets. Buyers whose workstation requires ECC, registered DIMMs or a higher memory ceiling will need a different solution.

Spurningar um þessa vöru

How do I install the 260-pin SODIMM modules in the HP ZBook 15u G4 and what step is often missed?

Power off and unplug the laptop, remove the bottom cover, insert each module at a 30-degree angle into the slot until the gold contacts are hidden, then press down firmly until both side clips click — the step people miss is not pressing hard enough to engage both clips.

What maintenance or replacement will this 32GB DDR4 kit need later?

No routine maintenance is required; the modules have no heat spreader and run at 1.2V, so replacement would only be needed if a stick fails, at which point you would swap the faulty 16GB module for another DDR4 2133MHz CL15 SODIMM.

What limit appears first under sustained heavy workloads with this memory?

The 2133MHz speed and CL15 latency set the bandwidth ceiling, so sustained throughput is limited by the DDR4 17000 rating rather than thermal throttling, since the unbuffered modules operate at standard 1.2V without a spreader.
