Compatible HP Upgrade

This 8GB DDR4 SODIMM matches HP part number T7B77AA and is built with major-brand chips from Samsung, SK Hynix or Micron. It delivers 2133MHz speed at CL15 latency with a low 1.20V operating voltage. The unregistered 1Rx8 module fits laptops and compact systems requiring 288-Pin DDR4 memory. It is designed for users who need a direct OEM replacement without compatibility guesswork.

Sustained Workload Behaviour

The module maintains its rated 2133MHz throughput during extended multitasking, rendering or data-processing sessions. With ECC enabled, it corrects single-bit errors on the fly to keep data intact over long runs. The 1Rx8 organisation allows the memory controller to access the full 8GB capacity efficiently. Performance stays consistent because the chips meet or exceed the original HP specifications for timing and signal integrity.

Thermals Noise Power

Operating at 1.20V keeps power draw low and reduces heat output inside tight laptop chassis. The SODIMM runs passively with no fan, so it adds zero acoustic noise to the system. Lower voltage also means less strain on the notebook's voltage regulators during heavy memory workloads. This combination helps preserve battery life and keeps internal temperatures manageable during typical daily use.

Questions about this item

How much heat and power does the 1.20V DDR4 module draw when running continuously?

The module operates at 1.20V, which is the standard low voltage for DDR4, keeping power draw and heat output low during all-day use.

What must my system already have to accept this 288-pin DDR4 SODIMM?

Your laptop or server needs a free DDR4 SODIMM slot that supports 2133 MHz, CL15 timing and 1.2V unregistered ECC memory.

Will this 1Rx8 ECC stick work alongside older non-ECC DDR4 modules I keep installed?

Mixing ECC and non-ECC modules is not recommended; the system will typically disable ECC or fail to boot when ranks and error-correction types differ.
