    OK big issues here, I updated the BIOS using @BIOS and just limped back into Windows. Everything is running fairly slow.. I backed up my old BIOS and could re-install that however @BIOS isn't loading for me now. Could someone please recommend another bit of software so I can load my old BIOS?

    I should note, windows tried to repair itself when the new BIOS was installed.. I see mention of a Service Pack in that error and I wonder if I was to restart my PC and let the windows update do its thing it might be right? But I'm scared to restart my PC now that I have it running.

    Have you pulled two sticks? The new BIOS might determine that some memory is bad and that's why it's slow.

    Pull two and see. I doubt the Windows update is a contributor at this point, but you never know.

    Check this BIOS setting
    2. If your BIOS is flash protected, please do not enable BIOS Flash Protection under Advanced CMOS Setup (AMI BIOS) or Advanced BIOS Features (AWARD BIOS) in BIOS menu.

    See this guide and try booting into safe mode with networking (you don't have to worry abut terminating TSRs)Then run the utility and try getting from the gigabyte site.

    IF you cannot use the Internet option, download and unpack F11 BIOS and follow the instructions for using a local flash
    edit: F11 BIOS download

    Check this BIOS setting

    First I really recommend you read or find your owners manual on the various flashing options. Then, if you choose to use @BIOS, read the instructions posted by Slartybart.

    If you're not doing these things, or not using the correct tools, you will run into problems, to include killing your motherboard. If you're unfamiliar with flashing a BIOS, I highly recommend you find someone near you who does know how to.

    Also, if you do choose @BIOS get it from here, but DO NOT download the one for the X79 chipset, but the one beneath it. You can also use QFlash from your BIOS to flash as well. But, I say again, READ the instructions before doing any flash.

    Whichever flash method you choose, you still need to download the BIOS itself. And since you have revision 1 of the motherboard (revision 2 didn't have an F5 BIOS), you need to get your BIOS update from here... GIGABYTE - Motherboard - Socket 1156 - GA-P55A-UD3 (rev. 1.0). Using the wrong revision can cause problems. I also pointed out the correct BIOS you needed in post 25...

    You'll need to download the latest BIOS from here first before proceeding to use @BIOS
    Now, once you do flash the BIOS, you'll need to enter the BIOS and choose Load Optimized Settings so that the BIOS can setup the proper parameters to run the system.

    Lastly... I asked a few times (posts 18, 35, 38) about providing use some info on the memory and as of yet those questions have not been answered. We can not help you if you don't answer the questions posed.

    Let us know.

    Way back in the thread nolube stated he had tried his room-mates ram 8gb and the board only saw 4Gb of it. If he can update the bios the issue will be solved I am sure of that.

    We've been saying that since post 13 (page 2)

    The problem now is the OP appears to be having issues flashing the BIOS. I suspect however that something isn't being done right. Thus the post above yours :)

    Memtest shows 3 with that part number and another different one. Try running the PC with the odd one just for grins and giggles.

    Thanks Nolube

    Can you post a shot of the module that is different?
    Or better for lookup - post the KVR number.

    I tried to lookup the 99U5458..... number before, but Kingston said "I don't know what that is"
