Ordering form

Tray OPN

Documented selection limits

Exact Tray OPN from manufacturer; not the boxed retail package. Cooler, board, and installed RAM are not included by inference. 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.
