    65 nm versus 45 nm Lithography for E6300 and  E6700

    Daniel357

      I currently have a DXP061 Motherboard from Dell running the latest Firmware 2.5.3 and happily running an Intel® Core™2 Duo Processor E6300 (2M Cache, 1.86 GHz, 1066 MHz FSB). I would like to upgrade to an Intel® Pentium® Processor E6700 (2M Cache, 3.20 GHz, 1066 FSB). Both CPU’s are Sockets Supported LGA775, FSB speeds are the same however the only difference I can see is that the existing CPU has a Lithography of 65 nm whereas the CPU I want to purchase has a Lithography of 45 nm. Will this CPU work with my existing Motherboard?

          We rely on the motherboard and system manufacturers to maintain such compatibility information because their testing requires the use of our processors (not vice-versa). The board must be validated for the power and thermal specifications of the processor. The manufacturer must release a BIOS update for the board with explicit support for the stepping and frequency of the processor. They should also provide any configuration changes or updates specific to the board.

           

          Compatibility and upgrade information must be specific to a motherboard, and it must come from the motherboard manufacturer.

           

          We recommend contacting the motherboard manufacturer for compatibility information between the Intel(R) processors and your motherboard.
