    Intel's is readying a hardware update for its P55 Express chipset, currently the only core-logic for the company's brand new socket LGA-1156 processor platform. The new B3 stepping of the P55 PCH will bring with it a little more than new MM number and S-spec numbers. A list of changes is as follows:
    • New MM number and S-spec numbers for the converted products;
    • Firmware and minor BIOS updates are required with the conversion;
    • Processor MRC/microcode update required to enable future processors;
    • Recommended storage driver upgrade from Intel MSM 8.9 to Intel RST 9.5.
    Although it is listed that the MRC update enables 'future processors', Intel, in a statement issued to X-bit labs assured that the current B2 stepping of the chipset (found on current socket LGA-1156 motherboards) does not leave out support for any of Intel's new LGA-1156 processors that are slated for release in the very near future. The dual-core "Clarkale" 32 nm processor will be supported by both B2 and B3 steppings of the chipset.

    P55 B3 stepping is pin-identical to P55 B2, and hence motherboard vendors will not have to come up with new designs. Sampling of the new stepping began as early as on October 02, 2009, and it is scheduled for shipment to manufacturers by the 7th of December, 2009. P55 is the performance core-logic for the LGA-1156 platform. It supports Core i5 and Core i7 "Lynnfield" processors with discrete graphics.

    Then what's the point? To be able to support the processors without a BIOS update? Are there any benefits to getting a new board?

    this messes with things


    imagine the confusion when some P55's support CPU's and others dont... mobo manfuacturers are likely to be slack with this

    I'm pretty sure this is why motherboards have revision numbers on them.

    indeed, but so few places list those revisions when you buy the board.

    i've gotten stung with that before, ordered a motherboard online with no mention of revision and received an outdated one with inferior CPU support

    (and recently too, with an AM2+ motherboard from gigabyte)
