Frequently Asked Questions
What type of memory does my desktop use?
Desktop computers use DIMM (Dual Inline Memory Module) modules. Most modern desktops use DDR4 or DDR5 DIMMs. Check your motherboard's specifications to determine which generation and speeds are supported. DDR4 and DDR5 are not interchangeable.
How many memory slots does my desktop have?
Most desktop motherboards have 2 or 4 memory slots. Some high-end boards have 8 slots. Check your motherboard's manual or specifications to see how many slots are available. For dual-channel performance, use 2 or 4 modules of the same capacity and speed.
Can I mix different memory speeds?
You can install memory modules of different speeds, but they will all run at the speed of the slowest module. For best performance, use identical modules from the same kit. Mixing different brands or capacities can sometimes cause stability issues.
