What the Pentium 4 519K is

The Intel Pentium 4 519K is a 3.06 GHz single-core desktop processor from 2005. It runs one NetBurst core at 3.06 GHz with no Hyper-Threading, so 1 core gives 1 thread. Cache is 1 MB of L2 on a 90 nm process. Power is rated at 84 W on LGA 775.

The 519K served mainstream LGA 775 towers on a 533 MT/s bus with a 23x multiplier. The table gives the year 2005 without a month against January 2005 in cpu_list, and the year is used here. Two identical cpu_list rows share this page as one SKU. It exists because buyers wanted a 3.06 GHz Prescott without Hyper-Threading.

Socket and motherboard compatibility

The 519K drops into LGA 775 boards with DDR2 memory and a BIOS that lists Prescott 5xx parts, such as 915 boards. It pairs with mainstream chipsets contemporary with Prescott. 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 533 MT/s front side bus ties the CPU to the chipset. PCIe or AGP slots hang off the chipset.

Cooling is any 84 W rated LGA 775 heatsink on the 72 mm mount.

Upgrade paths

On LGA 775 the upgrade is the Intel Pentium 4 HT 524 at 3.06 GHz for Hyper-Threading at the same clocks, or the Intel Pentium 4 511 at 2.8 GHz for a lower cost. Beyond LGA 775 a move to a newer platform needs a new board and memory.
