Product and Performance Information


1. System resources and hardware (such as PCI and PCI Express*) require physical memory address locations that can reduce available addressable system memory. This could result in a reduction of as much as 1GB or more of physical addressable memory being available to the operating system and applications, depending on the system configuration and operating system.

2. Intel® High Definition Audio (Intel® HD Audio) requires a system with an appropriate Intel® chipset and a motherboard with an appropriate codec and the necessary drivers installed. System sound quality will vary depending on actual implementation, controller, codec, drivers, and speakers.
