Core Black 18-inch UHD+ Mini LED
This 18-inch laptop pairs a 3840 by 2400 Mini LED panel at 120Hz with an Intel Core Ultra 9 285HX processor and an NVIDIA RTX 5090 laptop GPU carrying 24GB of GDDR7 video memory. The 24-core CPU reaches a 5.5 GHz maximum turbo frequency and includes 36MB of L3 cache. Windows 11 Pro comes pre-installed on the 1TB PCIe 4.0 NVMe SSD.
Gelid GC Extreme thermal compound upgrade
HIDevolution applies Gelid GC Extreme thermal interface material to both the CPU and GPU during assembly. The upgraded compound lowers system temperatures under heavy load and reduces the likelihood of thermal throttling during sustained compute or graphics workloads. The build also includes a full quality-control pass with updated BIOS, driver installation, burn-in stress testing, and physical inspection before shipment.
128GB DDR5 5600 dual-channel memory
Two 64GB DDR5 5600 modules provide 128GB of system memory running in dual-channel mode for memory-intensive applications and multitasking. The chassis measures 15.91 by 12.09 by 1.26 inches and weighs 7.94 pounds. Integrated LAN and WLAN handle wired and wireless connectivity. The system carries a one-year warranty covering the customizations performed by the authorized BTO dealer.

Questions about this item
Will the 128 GB DDR5 memory need to be replaced or can it be expanded later?
The laptop ships with two 64 GB DDR5 modules filling both slots, so any future increase would require replacing the existing sticks rather than adding to them.
Which component hits its thermal limit first during extended heavy loads on the Ultra 9-285HX and RTX 5090?
The CPU and GPU share a cooling solution upgraded with Gelid GC Extreme thermal compound, and either processor can reach its throttle point first depending on the workload mix.
How loud and hot does the 18 inch Mini LED chassis get when the system runs all day at 5.5 GHz turbo?
The Gelid GC Extreme paste lowers peak temperatures under sustained turbo, but fan speed and surface heat will still rise noticeably during continuous maximum performance.
