Important Configuration Notes
- MODULES MUST BE ORDERED AND INSTALLED IN PAIRS for Dual Channel mode.
- Faster memory will clock down to run at optimal speed depending on processor model and number of modules installed.
- Depending on which processor you install, different memory modules are supported. For ECC support please see motherboard manual. Mixing ECC and non-ECC modules is not recommended.
