Slot Configuration

More P55: Gigabyte's MicroATX Board And Asus' Flagship
By
Slot Configuration

A larger motherboard means more room for expansion. The P7P55D Deluxe sports three PCI Express x16 slots, two x1 slots, and two PCI slots.

Broken down, though, the true link speeds are a bit different. The first x16 slot runs at x16 signaling with a single card plugged in. It drops to x8 with two graphics cards installed in an SLI or CrossFire arrangement, due to Core i5's on-die capabilities. The third slot runs at x4 speeds so that there's enough PCI Express left over for the two x1 slots, one of the two gigabit controllers, and additional SATA connectivity.

You can also see the unique retention mechanism attached to all three x16 slots, which make it easy to secure and release graphics cards from either side of the slot. This is a big improvement on some of the other solutions out there that require pressing on the side of the slot or pulling a tab away from the slot to free an installed add-in board.

    I'd switch between the PCI / PEGx4 so it'd be possible to use a dual slot primary display card and an additional, low(er) bandwidth PEG card (storage, physics) without cutting half of the primary card's lanes.
    but that's me. i believe gigabyte has better understanding of the cuntemporary expansion card assortment than me.

    I love that on the last picture the socket cover says FOXCONN.

    Socket covers have said foxconn for ever...as do the metal housing around USB ports at rear I/O and many other parts. This is nothing new.

    Unless these are much cheaper, I still don't see why one should just avoid x58 and an i7 920 given how cheap 920's can be found now (as low as $200)

    Anyone else notice that all of these models have a huge amount of voltage regulators......so far much more than is common on x58 boards :(  (my Asus Rampage II GENE only has 6 vs 14 on that gigabyte board!?)

    P55 will be (hopefuly) much cheaper than X58 boards. entry/mid models at least. given that all sources hint that the difference in performance between i7/i5 is negligible (bar memory-bandwidth hungry apps. namely, sandra), i think that lower platform cost will make i5 the best option for anything between midrange and high-end systems, with i7 reserved for competitive benchers/OCers, uncle scrooge and the such.

    I really enjoy reading the articles you have here. I'm not a very participatory member, but I do read a lot and I have always enjoyed the articles here.

    I always check your site before upgrading my computers. Very informative.
    I love these two boards from two of my favorite manufacturers. When I can finally afford a second video card, I will look into these boards further.
