Will XD-capable processors cost more?

XD/NX-capable chips will be sold at approximately the same or slightly higher cost compared to

versions without XD bit.

When will they start showing up in the HP desktops I purchase?

HP is shipping:

• i915 chipset desktop systems with XD disabled in F10 Setup.

• i945 chipset desktop systems with XD enabled in F10 Setup.

What HP commercial desktops support this technology?

• dc5100

• dc7100

•dc7600

•dx5150

•dx6100

• dx7200

• bc1000

What HP workstations support this technology?

• HP Workstation xw4200

• HP Workstation xw6200

• HP Workstation xw8200

If the processor is changing, is the chipset changing as well?

For Intel-based systems, newer chipsets, starting with the i915 chipset, provide support for XD.

Will the system board change with the processor change?

Intel chipset-based HP system boards support a wide range of Intel processors. You should not

have to change system boards when upgrading processors unless the new processor requires:

• Power output that the current system board does not support.

• A different chipset than what is on the system board.

Will my current applications work with this new technology?

In “Known Issues” on page 13, review the table that provides a list of applications currently

known to not function properly with XD/NX. The table also lists links to Microsoft Knowledge

Base articles about incompatibilities found during XD/NX testing.
