Dimm slots are a type of expansion card slot found on motherboards. A dimm slot is a type of expansion card that uses removable modules, or “dimmables”.
A typical dimm module contains two PCI-E x16 slots, four PCI-E x1 slots, and two M.2 slots for SSDs.
Dimm slots provide increased PCIe bandwidth and storage capacity for high-end graphics cards and other system components. They are also popular for adding extra hard drive bays to a computer.
Some motherboard manufacturers offer pre-installed dimm slots on their models, while others allow users to install dimm modules themselves. There are also third-party vendors that sell dimm slots and compatible modules.
The popularity of dimm slots has led to the development of specialized cards called “dimmable graphics cards”. These cards can be switched between using regular PCIe connections and dedicated dimm slots, allowing them to handle heavier graphics loads without slowing down the rest of the system.
