Product FAQ

How do I know which generation I need?

DDR3, DDR4 and DDR5 are keyed differently and not interchangeable. Check your motherboard specification or run CPU-Z. The Memory tab shows your current generation.

Can I mix this with my existing stick?

Same generation and voltage usually works, but matched pairs are recommended for stable dual-channel operation.

Desktop or laptop module?

UDIMM is the long desktop module; SODIMM is the short laptop/mini-PC module. Check the specification row above.

Is this genuine PowerX stock?

Yes. Every SKU ships from our own verified inventory with a PowerX warranty card inside.
