RAM is one of the safest PC components to buy used. Memory modules have no moving parts, rarely degrade, and typically either work perfectly or not at all. On Koukan, buyer protection ensures you can inspect, test, and report issues if it does not work as described.
Your motherboard determines which RAM type you need. Older platforms (Intel 12th gen and below, AMD AM4) use DDR4, while newer platforms (Intel 13th/14th gen, AMD AM5) may support DDR5. DDR5 offers higher bandwidth but DDR4 is more affordable on the used market. Check your motherboard specifications before purchasing.
Ensure the memory type (DDR4 or DDR5) matches your motherboard. Check the speed rating and CAS latency for performance matching. Buying matched kits sold together as a pair is important for dual-channel performance. Verify the listing includes the correct number of sticks and total capacity.
