Suits ECC registered platforms only

This memory suits administrators upgrading or repairing the listed Lenovo System x M4 servers that require DDR3L ECC registered DIMMs. It will not work in standard desktop computers or consumer laptops. It cannot be mixed with unbuffered memory modules. Buyers who need unbuffered DDR3L or non-ECC memory should look at a different product line.

Check server model and slot requirements

Before ordering, confirm the exact Lenovo System x model matches x3300 M4, x3500 M4, x3530 M4, x3550 M4 or x3630 M4. Verify the system accepts 240-pin DDR3L 1.35V registered DIMMs and that the memory configuration supports 1Rx4 modules. Consult the server documentation for maximum capacity per slot and population rules.
