In-Depth Information
For this reason, you cannot use Intel 915 and 925 chipsets and some third-party chipsets
made for the Pentium 4 with the Pentium D or Pentium Extreme Edition. Intel's 945
series, 955X, and 975X desktop chipsets, and the E7230 workstation chipset, are the first
Intel chipsets to support these processors. The nForce 4 series from NVIDIA also works
with these processors.
See Intel 945 Express Family ,” p. 193 and Intel 955X and 975X Family ,” p. 194
( Chapter 4 , Motherboards and Buses ”), for more information on these chipsets.

• Clock speeds of 2.66GHz-3.6GHz
• 533MHz or 800MHz processor bus
• EM64T 64-bit extensions
• Execute Disable Bit support
• 65- or 90-nanometer manufacturing process
• 2MB/4MB L2 cache (1MB/2MB per core)
