Large-screen workstation laptop

The HP OmniBook 3 is a 17.3-inch Windows 11 Pro laptop built around an Intel Core Ultra 7-255U processor with 12 cores and 14 threads. It ships with 64GB of DDR5 memory and a 4TB PCIe NVMe SSD, both installed by the integrator before delivery. Integrated Intel Graphics drives the IPS panel at 1920 x 1080 resolution and 60Hz refresh.

Suited to memory-heavy single-machine workflows

Analysts, developers and content creators who need a large display, very high RAM capacity and multi-terabyte storage in one chassis will match this specification. Buyers who require a dedicated GPU for 3D rendering, a touchscreen, or a lighter device for frequent travel should consider other form factors.

64GB DDR5 soldered configuration

The memory is populated as 64GB of DDR5 SO-DIMM with no free slots mentioned, so the capacity is fixed at purchase. If your workload demands more than 64GB or user-replaceable modules, this unit cannot meet that requirement.

Questions about this item

How is the DDR5 memory installed and what step do people miss?

The 64GB DDR5 SO-DIMM is factory-installed by Velztorm technicians; the unit ships sealed with no user-accessible memory slots, so there is no installation step for the buyer to miss.

What maintenance or replacement will the 41 WHr battery need later?

The 3-cell 41 WHr battery is internal and not user-replaceable; when capacity degrades, service requires a qualified technician to open the chassis and swap the pack.

What limit appears first during sustained loads on the Ultra 7-255U?

The 45W Type-C power adapter and 41 WHr battery constrain sustained turbo performance, so the 5.2 GHz boost clock will throttle before thermal limits are reached.
