⚙️ Fit Notes

• Confirm that the system requires a 260-pin DDR4 SO-DIMM, not a 288-pin desktop DIMM.
• This listing is specifically for 1Rx8 memory. Do not substitute a 1Rx16 or 2Rx8 module when the system or application requires the exact 1Rx8 organization.
• This is non-ECC, unbuffered memory. It cannot be mixed with ECC memory and should not be installed in an ECC-only system.
• It is not compatible with DDR3, DDR3L, DDR5, registered DIMM, RDIMM, LRDIMM, or desktop UDIMM sockets.
• Actual operating speed is controlled by the processor, chipset, BIOS, and other installed memory.
• When mixed with slower memory, all installed modules normally operate at the slowest mutually supported speed.
• Matching capacity, rank, speed, and timings is recommended for dual-channel operation.
• Certain thin laptops combine soldered memory with one removable SO-DIMM slot. Install this module only in the removable slot.
• Some systems sharing the same model family were manufactured with different memory technologies. Verify the current module before purchase.
• Disconnect external power and the internal battery where service procedures require it before installing memory.
