What the Pentium 4 HT Extreme Edition 3.73 is
The Intel Pentium 4 HT Extreme Edition 3.73 is a 3.733 GHz single-core enthusiast processor from February 2005. It runs one NetBurst core at 3.733 GHz with Hyper-Threading, so 1 core gives 2 threads. Cache is 2 MB of L2 on a 90 nm process. Power is rated at 115 W on LGA 775.
The 3.73 brought the Extreme Edition to LGA 775 on a 1066 MT/s bus with a 14x multiplier at about 999 dollars launch price. It exists because enthusiasts wanted an Extreme part with 2 MB of cache on the faster 1066 MT/s bus.
Socket and motherboard compatibility
The 3.73 drops into LGA 775 enthusiast boards with DDR2 memory and a BIOS that lists Prescott Extreme parts on 1066 MT/s, such as 925XE boards. Boards need voltage regulator support for the 115 W envelope. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is DDR2 through the board chipset in two channels.
A 1066 MT/s front side bus ties the CPU to the chipset. PCIe slots hang off the chipset.
Cooling is a 115 W rated LGA 775 heatsink on the 72 mm mount.
Upgrade paths
On LGA 775 the upgrade is the Intel Pentium 4 HT 672 at 3.8 GHz for higher clocks at 115 W, or Gallatin Extreme parts for L3 cache. Beyond LGA 775 a move to a newer platform needs a new board and memory.
