How to interpret these tiers
OEM
OEM parts are certified for a specific server vendor and may carry firmware locks, qualification, and higher warranties. They often price higher due to supportability and vendor validation.
Original
Original parts are the underlying manufacturer modules (e.g. Samsung/Micron/Hynix) that may be used across multiple platforms. They can offer strong compatibility without the OEM premium.
Compatible
Compatible parts are third-party alternatives that match the canonical spec. They may be cheaper but can trigger OEM warnings or have varying validation—always verify compatibility for your target platform.
