Processors

NOTE:

Global Standard Products (GSP) are a subset of Dell’s relationship products that are managed for availability and

synchronized transitions on a worldwide basis. They ensure the same platform is available for purchase globally. This

allows customers to reduce the number of configurations managed on a worldwide basis, thereby reducing their costs.

They also enable companies to implement global IT standards by locking in specific product configurations worldwide.

Device Guard (DG) and Credential Guard (CG) are the new security features that are only available on Windows 10 Enterprise today.
Device Guard is a combination of enterprise-related hardware and software security features. When you configure together, it locks a
device down so that it can only run trusted applications. Credential Guard uses virtualization-based security to isolate secrets (credentials)
so that only privileged system software can access them. Unauthorized access to these secrets can lead to credential theft attacks.
Credential Guard prevents these attacks by protecting NT LAN Manager (NTLM) password hashes and Kerberos Ticket Granting Tickets.

NOTE:

Processor numbers are not a measure of performance. Processor availability is subject to change and may vary

by region/country.

Primary storage

Precision 3640 supports up to 4x 2.5" HDD or up to 3x 3.5" HDD. Also, Precision 3640 supports up to 3x M.2 NVMe SSDs. (2x via M.2
2280 slots on motherboard and 1x via Dell Ultra Speed Drive)

Your computer supports one or any combination of the following storage configurations:

• 4x 2.5 inch SATA hard-disk drive or

• 3x 3.5 inch SATA hard-disk drive and

• 2x M.2 2280 NVMe solid-state drive (class 40 or 50)

NOTE: 1x 2280 NVMe SSD on optional PCIe SSD M.2 Interposer Card (Dell Ultra Speed Drive).

The primary drive of your computer varies with the storage configuration. For computers:

• Change the NVRAM settings after you add or remove hardware

• View the system hardware configuration

• Enable or disable integrated devices

• Set performance and power management thresholds

• Manage your computer security

BIOS overview

The BIOS manages data flow between the computer's operating system and attached devices such as hard disk, video adapter, keyboard,
mouse, and printer.
