LGA 775 CPU's

Hello all.

Can someone tell me if the older LGA 775 CPU's come with a 32 bit instruction set or do they all have a 64 bit instruction set ?

Thanks in advance

Victor

  1. Some of them have 32bit.
  2. Thanks for the reply.

    That was I had thought too. I was on a motherboard website and noticed there were 32 bit drivers available along with 64 bit ones for a LGA 775 board. So I would imagine that the older Pentium CPU's that were LGA 775 like maybe the Pentium 4 were 32 bit versions ?

    Thanks

  3. You can check here: http://ark.intel.com/ Look at all of the core 2 duo's, pentium 4's, and core 2 quads.

    The very first LGA 775 processors were the Pentium 4 5xx series. They were 32 bit only.

    The second LGA 775 chips were the Pentium 4 6xx series and they had 64 Bit instructions. All Intel desktop processors since are 64 bit. So the Pentium 4 6xx, Pentium D 8xx, Pentium D 9xx, Core2duo E6xxx, E7xxx, E8xxx and Core2Quad Q8xxx and Q9xxx all have 64 bit.

    64 bit drivers did not become necessary for most people until Windows 7 though. Windows XP x 64 was not a very good OS and it was hard to find drivers for. Only with Windows 7 and people running more than 4GB of RAM has 64 bit become commonplace.
