⚙️ Fit Notes

• This module is for systems that require DDR4 ECC Registered RDIMM memory
• This module is not compatible with DDR4 UDIMM, desktop DIMM, or laptop SO-DIMM platforms
• This module is not compatible with LRDIMM-only configurations unless the system also supports standard RDIMM
• Always match memory type, registered/buffered type, voltage, and speed class before ordering
• Systems limited to lower DDR4 speeds may use this module at the platform's maximum supported speed
