Intel Pentium 4 3.46EE (1066MHz FSB)
 

Intel has been at the forefront of the revolution that has taken personal
computing by storm. They were the first ones to offer both DDR2 and PCI-E
solutions to users, they introduced their 900 series chipset and their
line up of LGA775 package CPU’s. The entire platform changed except the
processor. This came as a bit of a shock to everyone. What was the point
in upgrading an entire system just to end up with the same processor?
Today, Intel has rectified this problem. With the introduction of their
newest chipset, the 925XE, Intel has added support for 1GHz+ FSB to their
motherboards and processor lines. The first processor to support the
1066MHz (1.06GHz) FSB is Intel’s Extreme Edition. What they have done is
taken their 3.4EE and lowered the clock multiplier to accommodate the
higher FSB which has resulted in the 3.46GHz Extreme Edition processor.
