Targeted DDR4 SODIMM for HP ZBook

This 8GB DDR4 2133MHz CL15 module is built specifically for HP ZBook 14u G4, 15 G3, 15u G3, 17 G3 and Studio G3 mobile workstations. It uses a 260-pin SODIMM form factor operating at 1.2V without ECC or buffering. The memory is designed to meet JEDEC PC4-17000 standards for a direct, warranty-safe upgrade in those listed systems only.

Sustained load behaviour

As an unbuffered non-ECC SODIMM with CL15 latency, the module delivers consistent throughput for typical professional workloads such as multi-application editing and large dataset handling. The 1.2V operation keeps thermal output low during extended sessions, helping maintain stable frequencies without throttling in the compact chassis of the compatible ZBook models.

DDR4 SODIMM interface limits

The DDR4 2133MHz interface caps bandwidth at the PC4-17000 specification, so total throughput cannot exceed that ceiling regardless of workload intensity. Capacity is fixed at 8GB per module, restricting maximum memory to the number of slots available in the target ZBook. Systems requiring ECC error correction or registered buffering cannot use this module.

Questions about this item

How much heat does the 1.2V DDR4 SODIMM produce when the HP ZBook runs all day?

The module operates at 1.2V without a heat spreader, so it adds minimal thermal load inside the chassis.

What must the HP ZBook already have for this 260-pin DDR4 module to work?

The laptop needs a free DDR4 SO-DIMM slot that accepts 260-pin unbuffered non-ECC memory.

Will this CL15 2133MHz stick run correctly alongside the original memory in a ZBook 15 G3?

Yes, it matches the factory speed and latency, so the system will clock both modules to 2133MHz CL15 automatically.
