Product- en prestatiegegevens


1. Systeembronnen en hardware (zoals PCI en PCI Express*) vereisen fysieke geheugenadreslocaties waardoor het beschikbare adresseerbare systeemgeheugen kan afnemen. Dit kan leiden tot een afname van 1 GB of meer fysiek adresseerbaar geheugen dat beschikbaar is voor het besturingssysteem en toepassingen, afhankelijk van de systeemconfiguratie en het besturingssysteem.

2. Intel® High Definition Audio (Intel® HD Audio) vereist een systeem met een geschikte Intel® chipset en een moederbord met een geschikte codec en de nodige drivers. De geluidskwaliteit van het systeem is afhankelijk van de werkelijke implementatie, controller, codec, drivers en luidsprekers.
