3. Multi-Core is designed to improve performance of certain software products. Not all customers or software applications will necessarily benefit from use of this technology. Performance and clock frequency will vary depending on application workload and your hardware and software configurations. Intel's numbering is not a measurement of higher performance.
4. Each drive requires a PCIe x4 (minimum) slot to be available. Full performance is obtained only when using PCIe slots connected to the CPU. Non-CPU PCIe slots may see a decrease of up to 10%. Please see slot configuration recommendations at http://www8.hp.com/us/en/campaigns/workstations/z-turbo-drive.html. Note that graphics cards, Thunderbolt™, and other devices will require PCIe slots.
5. Some 3D graphics only available as AMO and are not available on small form factor configurations.
