Intel LGA775: The Complete CPU List

This table lists every production processor Intel released for LGA775, from the first Pentium 4 to the last Core 2, Pentium and Celeron models of 2010, plus the Core-based LGA771 chips (mostly Xeons) that run in a 775 board after a simple mod. Use the filters to narrow it down by family, FSB, TDP or features, or type a model number into the search box.

Specs come from open sources and may contain errors. Features can differ between steppings of the same model, so check the sSpec code printed on the CPU before buying. The sSpec codes under each model name are searchable; the lists are not exhaustive.

We only list chips with a production sSpec code confirmed by at least two sources. Engineering samples, cancelled models such as the Pentium 4 580, and CPUs that appear in just one online database are left out.

A CPU that fits the socket won’t necessarily run in your board

LGA775 lasted from 2004 to 2010, and boards from the start of that span can’t run the chips from the end. Three things decide it:

  • Chipset and FSB. The chipset must support both the CPU family and its bus speed. A 1333 MT/s Core 2, for example, needs a chipset rated for 1333 MT/s.
  • VRM. Core 2 processors need a board built for Intel’s VRD 11 spec. Many boards made for the Pentium 4 and Pentium D lack it and simply won’t start with a Core 2.
  • BIOS. 45 nm chips (Core 2 Duo E7000/E8000, Core 2 Quad Q8000/Q9000, Pentium E5000/E6000, Celeron E3000) often need a newer BIOS, and sometimes a newer board revision.

Our LGA775 guide covers each chipset in detail.

What “LGA771 + mod” means

Rows marked this way are server chips for LGA771. The socket is almost the same as LGA775, but the key notches and two contacts differ. With a sticker adapter, two cut plastic keys and a BIOS that includes the right microcode, many 775 boards with a Core 2-era chipset can run them. Watch out for the Core 2 Duo E6305/E6405, the Celeron 445 and the Core 2 Extreme QX9775: the names look like desktop parts, but these are LGA771 chips too.

The full procedure is in our Xeon 5000 series guide. Ready-made BIOS files are in our modified BIOS collection, and tested boards are listed in the Xeon compatibility list.

For the socket that came before, see the Socket 478 CPU list, which covers the earlier Pentium 4, Celeron and Celeron D chips. AMD’s rivals from the Core 2 years, the Athlon 64 X2 and Phenom, are in our AM2/AM2+ CPU list.
