Questions about this item

Can the 64 GB DDR5 5600 memory be upgraded later?

The laptop ships with 64 GB of DDR5 5600 RAM; any future upgrade would require compatible DDR5 modules and available SO-DIMM slots.

What thermal limit appears first when the Core Ultra 9 275HX and RTX 5070 run at full load for hours?

Sustained 240 W adapter draw and the 90 Whr battery capacity define the power ceiling before temperatures throttle the 24-core CPU and 8 GB GDDR7 GPU.

How loud do the fans get and how hot does the chassis feel during an all-day gaming session?

Dual-fan cooling moves heat from the 24-core processor and RTX 5070 through rear and side vents; surface temperatures rise around the keyboard deck and exhaust areas under continuous load.
