Description
Intel Pentium 4 SL6D7 2.40GHz 512KB 533MHz FSB 1.5V Socket 478 CPU Processor
The Intel Pentium 4 SL6D7 is a 2.40GHz desktop processor built on Intel's Northwood core — a 0.13-micron die shrink that brought improved performance and lower power consumption compared to its Willamette predecessor. It runs on a 533MHz front side bus with 512KB of L2 cache and operates at 1.5V core voltage, fitting the Socket 478 (mPGA478B) platform. The processor is marked "MALAY" indicating Malaysian manufacture, consistent with Intel's Kulim facility production during this period.

Applications
The Pentium 4 Northwood was Intel's mainstream desktop CPU from roughly 2002 through 2004, targeted at home PCs, workstations, and entry-level servers of that era. The 533MHz FSB variant like this SL6D7 was compatible with a wide range of Socket 478 motherboards using chipsets such as the Intel 845, 845E, 845G, 845GE, 845GL, 845GV, 850E, 865PE, 865G, and 875P — giving it broad motherboard compatibility across that generation. These processors were used in systems running Windows XP, Windows 2000, and early Linux distributions of the period. Today, Socket 478 Northwood CPUs are sought after for legacy system restoration and repair, retro PC builds, and replacing failed processors in vintage workstations and industrial computers that ran on this platform. The Northwood 2.4GHz/533 remains one of the more capable variants at the lower end of the 533MHz FSB lineup, making it a practical drop-in upgrade for older systems that may have shipped with a slower Willamette or early Northwood chip.
This Intel Pentium 4 SL6D7 2.40GHz Socket 478 CPU has been tested and is in good working order. The processor shows some thermal compound residue on the lid, which is typical of a pulled CPU and is easily cleaned before installation. The 478-pin contact array on the underside is intact with no bent or missing pins visible. This unit was pulled from a working system and is ready for use.
