Important Configuration Notes
- Systems based on Core i7 desktop processors support non-ECC UDIMM only. Systems based on Xeon E5-1600 v3 / E5-2600 v3 Series processors support either ECC UDIMM or RDIMM, with no non-ECC UDIMM support.
- Faster memory will clock down to run at optimal speeds depending on processor model installed.
- MODULES MUST BE ORDERED AND INSTALLED IN FOURS for Quad Channel mode.
- Kingston recommends installing modules in kits of four (K4) for Quad Channel mode.
- ECC Registered DIMMs and Non-ECC Unbuffered DIMMs cannot be mixed.
