    One of the ram (A1) slots on my Asus P7P55D-LE has failed I think. I have been having a lot of BSOD's with no apparent reason, I have even reinstalled Windows 7 today hoping that might sort the issues.
    I was in the bios and noticed that only 2GB of my 4GB was showing. So switched off and removed the two sticks and just putting one in the A1 slot,got some very nasty beeps,so tried the other stick same thing.

    By this time I am becoming a tad puzzled as I had just finished installing Windows etc. after a bit of trying various combinations I have discovered that my PC will not boot with one stick only in slot A1 or just in B1 but will boot if a stick is in A1 and B1 but only 2GB is showing.

    I am thinking that a fault in slot A1 so I am looking for an i5 crossfire/sli board compatible with
    my OCZ 4GB (2x2GB) DDR3 1333MHz/PC3-10666

    Don't really want to spend more than £100 less preferably.

    Suggestions welcomed

    A bit more than I want to spend after factoring in postage.
    Thanks anyway.

    Maybe this?

    I used to have a P55-GD65 and it was ace, clocked my i5 750 to 4GHz with minimal effort, and was very reliable. Obviously this one is cheaper so will probably not be as good, but reading the spec it seems OK...

    crossfire/SLI on a p55? thats a poor idea IMO. the P55 doesnt have the bandwidth to support multiple GPUs properly. even if the board will technically do it, your looking at 8x/4x or even 4x/4x in many cases. youd get better performance out of a single high end card.

    just my $.02 as a fellow P55 owner :cooldude:

    The reason I suggested crossfire/SLi is that I have at the moment 2 Sapphire ATI Radeon HD 5770 Vapor-X 1024MB graphics cards and certainly do not have the cash to upgrade my graphics cards to 1 high end.

    Thanks all,went for 'Reddoguk's' suggestion.
    Thanks for the pointer for paying no postage with Scan, very helpful.

    Also discovered that this is quite a common fault with this board and also as it is less than 9 months old I can return it and as Ebuyer do not stock the board will get a credit.

    So things have worked out just fine.

    Thanks again.

    from what i believe thats only with no card in the slots, once there is one the sata/usb 3.0 speeds get halved

    sata/usb 3.0 is user controlled on the UD3 (i cant speak for other boards), and it takes its bandwidth from the primary PCIE slot. so with USB/SATA 3.0 enabled, you can run 8x with one card or 4x/4x crossfire. or you can run 16x single or 8x/4x crossfire with USB/SATA 3.0 disabled in bios.

    sure they didnt have a problem with 4x/4x but how does the performance compare to a single 16x or 8x card...my guess is there wouldnt be any performance gains with the 4x/4x setup either. also suppose you have more than one display (dont most people running sli/crossfire?), whats going to bottleneck first, the 4x/4x setup or a single 16x or 8x card?

    i remember seeing a review (thought it was toms hardware) comparing 16x/16x, 8x/8x, and 4x/4x back when i was contemplating crossfire on my board that showed something like a 30% drop in performance for the 4x/4x setup, but now i cant seem to locate it. ill do some more searching when i get home :duh:

    most boards £100+ do 1 16x and 2 at 8x.

    Did you even read the headline of the review and the review itself? They reviewed GTX 480 SLI PCIe Bandwidth Perf. - x16/x16 vs. x4/x4. So why would a single card performance make any difference.

    the GAP55AUD3 is still a $130 board and it runs at 8x/4x max. i had a quick gander at neweggs P55 boards and it seems most of the sub $200 boards that support sata 3 offer 8x/4x or 16x/4x, at least according to neweggs info which can be a little misleading as it makes my board look like it should be 16x/4x too.

    i give. ive been searching for an hour and a half for that stupid 4x/4x vs 16x bench that i found before and i cant find it. it was showing quite the opposite of the article that you posted but without being able to find it i got nothing.

    Is this the one? clicky

    It seems it doesn't make any real difference on regular resolutions.

    no, thats the same article steve posted. the one i had read compared 2 crossfire/sli cards at 4x/4x to one card running at 16x. the single 16x card won out which is counter to what that article is saying (obviously if 16x/16x and 4x/4x are on equal footing, than a single 16x doesnt stand a chance).

    for all i know, it could have been removed because it was bogus. googling P55 and crossfire still brings up plenty of arguments against the idea, so who knows.
