Article: Overclocking the Intel® Pentium® D 805 Processor (Dual Core for the Masses)

Target Audience: E/O/B (N=Newbie, E=Hardware Enthusiast, O=Overclocker, B=Budget
Many thanks to Intel® for providing the processor.

I. Introduction

The Intel® Pentium® D 805 Processor is the latest dual core processor released on the mainstream market. It is based on 90nm/Smithfield core on the LGA775 package, and is priced very attractively with an introductory price costing less than Php7,200.00 (~$13.009). This is the first Smithfield core that will be trully attractive to mainstream dual-core users, and of course overclockers who are always hunting things on the cheap.

Today users require the power of simultaneous computing found in a dual-core processor. The Intel® Pentium® D processor brings this power to the desktop. An Intel dual-core processor delivers consumer value by providing additional computing resources that expand the PC's capabilities and provide platform-level advancements for consumers in the form of higher throughput and simultaneous computing. With an Intel Pentium D processor users may perform multiple tasks such as digital rendering and gaming all while running virus scan or other background tasks seamlessly.. It has great features for digital home computing, such as support for EM64T to enable the system to address more than 4GB of system memory and advance security functionality thru Execute Disable Bit that can prevent certain classes of malicious "buffer overflow" attacks when combined with a supporting operating system.

This processor is slated as the lowest part number among the Intel® Pentium® D series that is based on the newer socket. And as such, this processor being the lowest-priced in its catagory, this will serve as a good starting point to push it up and see how this processor will fare in both in stock and overclock settings. Time to get this baby going, but first, let's lay down the details of this processor.

II. Specification

The Intel® Pentium® D 805 Processor is based on the new "socket" LGA775. It is based on the Smithfield core, with 2x1024KB of L2 cache. This processor is like an enigma, it is categorized within the Intel® Pentium® D 800 series that usually runs with 800MHz, and yet this little baby is somewhat like a strip-down version with just 533MHz PSB. However, it still has EM64T enabled, and have XD (Execute Disable) feature as well as Streaming SIMD Extensions 2 and 3. Like other non Extreme series, it doesn't have Hyperthreading.
