Overview
A 32GB DDR5 SODIMM kit (2x16GB) for laptops, running up to 5600MHz and built for 12th/13th gen Intel Core and AMD Ryzen 7000 platforms.
Crucial ships this as a matched dual-channel pair rather than a single stick, which is what a laptop with two SODIMM slots needs to actually hit dual-channel speeds. It supports Intel XMP 3.0 and AMD EXPO profiles for boosting past the base JEDEC speed, but actual clock depends on what the laptop's memory controller and BIOS allow, and it can also run down at 5200MHz or 4800MHz on boards that don't support the top speed.
- 32GB kit, 2x16GB SODIMM
- Up to 5600MHz, downclockable to 5200/4800MHz
- 262-pin, non-ECC, 1.1V
- XMP 3.0 and AMD EXPO support
Who it's for
Laptop owners upgrading or maxing out RAM for multitasking, content editing, or gaming, provided the laptop has two open or replaceable DDR5 SODIMM slots. Desktop builders need standard DIMMs, not this SODIMM kit.
Pros and cons
- Matched 2x16GB dual-channel kit, not two separate sticks
- Runs at 5600, 5200, or 4800MHz depending on the board
- Supports XMP 3.0 and AMD EXPO profiles
- Made by an established memory manufacturer
- SODIMM form factor only fits laptops with matching slots
- Actual speed depends on the laptop's own memory controller support
Performance notes
The kit is rated at 5600MHz with downclock options to 5200 or 4800MHz, so it will run on a range of DDR5 laptops even if the specific board can't reach the top speed. Being sold as a matched 2x16GB pair, rather than two separate sticks, is what lets a dual-channel laptop actually run both channels at the rated speed instead of falling back to single-channel timing mismatches.

Frequently asked questions
Will this work in a desktop PC?
No, this is a SODIMM kit for laptops. A desktop needs full-size DDR5 DIMMs instead.
Does it need XMP or EXPO enabled to run at 5600MHz?
The kit supports Intel XMP 3.0 and AMD EXPO profiles for the rated speed, though the actual speed also depends on what the laptop's own memory controller and BIOS allow.
Is this sold as two separate memory sticks or a matched kit?
It's a matched 2x16GB kit meant to run together in a dual-channel laptop, not two independently packaged sticks.
