HP Envy 27-b100 compatible DDR4 SODIMM

This 8 GB DDR4 2133 MHz CL15 module is built for the HP Envy 27-b100 series all-in-one desktops. It uses the standard 260-pin SODIMM form factor at 1.2 V and is unbuffered non-ECC. The 2Rx8 rank configuration matches the platform requirements.

Upgrade from lower capacity or slower DDR4

Adding this module increases total memory bandwidth for multitasking and larger datasets. The jump is worthwhile when the system currently runs with 4 GB or 8 GB of slower DDR4, or when free slots exist and the workload demands more simultaneous applications. Buyers needing ECC error correction or registered DIMMs cannot use this product.

Sustained load stability at JEDEC speeds

The module operates at the JEDEC-standard 2133 MHz with CL15 latency and 1.2 V, so thermal output remains predictable during extended sessions. Testing follows JEDEC and RoHS compliance, ensuring consistent throughput without throttling. It is not designed for overclocking or voltages above the rated specification.
