Documented selection limits

Model only; boxed/tray ordering variant and included cooler are not established. Confirm exact motherboard/server CPU support list, socket, firmware/BIOS, memory type and topology, VRM and CPU cooling limits. CPU TDP is a thermal specification, not a system PSU recommendation; Intel Processor Base Power and Maximum Turbo Power remain separate ratings, not AMD Default TDP. Memory limits, channels, ECC, PCIe lanes and clock rates describe processor support, not installed hardware. Maximum turbo/boost frequency is conditional, not a sustained all-core guarantee. Do not interchange generations merely because socket names match.
