The HP Envy x360 15 (2024) is a versatile convertible laptop blending performance with portability. Available with either an AMD Ryzen 7 8840HS or Intel Core Ultra 7 155H processor, it features a beautiful 15.6″ FHD OLED multi-touch display. Like most premium ultrabooks, it has limited upgradeability due to soldered memory and sealed chassis design.
This guide covers RAM, SSD, charger, dock, and specifications to help you understand upgrade options for your Envy x360 15 (2024).
RAM Compatibility & Upgrade Guide
The HP Envy x360 15 (2024) features LPDDR5X soldered memory (AMD variant) or LPDDR5X-7467 soldered memory (Intel variant). Both configurations are fixed at the motherboard and not upgradeable. Your RAM capacity is determined at purchase: 16GB or 32GB.
