Frequently asked questions
Can DDR5 memory work in a DDR4 motherboard?
No. DDR4 and DDR5 use different slots and require compatible motherboards and processors.
What case size do I need?
Choose a case that supports the motherboard form factor and provides enough room for the graphics card, cooler, drives, and cables.
How many case fans are necessary?
The answer depends on the case and components, but a simple front-intake and rear-exhaust arrangement is a common starting point.
