    Default Flashing P55-UD4 BIOS

    I know there is a huge flashing guide, but it seems a tad outdated or recomended settings dont match up with whats on my screen.

    The problem im having my pc wont stop crashing. Wether it be watching a video using flash player or playing a game, it just keeps crashing. The video card im using is a ATI 5870.

    I've being told by various people flashing my motherboard to the newest version might fix my problems, so I'm willing to give it a shot.

    I downloaded the newest BIOS files from Giagabyte's website and am trying to flash using Qflash.



    Now in the flashing guide, it says "keep DMI data disabled". I tried changing this, but it just will not change from enabled.

    This is as far as I've got as I thought id better check here before pressing yes to "are you sure you want to flash". Is it ok since I cant change DMI to disabled before flashing ?

    Secondly, I managed to backup my current bios, but it asks what would I like to call the file. What name should it be given so that if something goes wrong, I can just flash my old BIOS ?


    Thanks for your help.

    What needs changed in the guide? Sorry, please let me know as I know Gigabyte often changes wording of things.

    A BIOS flash may help, or may not, but I do always suggest using the latest. You may just need to set the proper settings per your hardware, but I can help you with that after you get your BIOS updated.

    How are you trying to change "Keep DMI Data", I mean what key are you using? This is not always a must anyway, just suggested. You can flash without it, just be sure to load optimized after you are done

    DMI is just part of what keeps your old BIOS configuration, recommending to disable this just helps users to not try and use their old exact settings and ensures that they load optimized defaults.

    You can save your BIOS anywhere such as on a USB Drive or FAT32 Partition on your hard drive, name it to anything you would like it does not matter.

    Let me know if you continue to have issues with Keep DMI Data and I will check to be sure what key you should be using to change this (Sorry can't remember right now), it also very well could just be a bug with your current BIOS/Qflash as I know they did update Qflash in P55 recently so this could have been a bug that update corrects.

    Again you will be fine without changing that, just flash and reboot back to the BIOS, then load optimized and F10 Save/apply and reboot back to the BIOS. Then make any needed changes you intend to make before going into windows, don't forget your SATA/Disk settings.

    Nevermind on the DMI settings, I fixed that and then did the flash.

    Problem was with numlock on, my page up and down keys did nothing. I turned numlock off and this worked fine. I loaded the optimized settings and windows booted. Only two issues is one, it removed my overclock and the store I bought it from will have to put it back on and secondly, now my pc tells me I have a floppy disc, when I dont.

    However still having crashes. Every other person I've come accross with the same error is using a 5 series ATI card with a gigabyte motherboard.

    I'm thinking of just swapping the motherboard out for an Asus equivalent. Otherwise my only other option is swapping the 5870 for an Nvidia GTX285 and take a 15-20% performance drop.

    Ahh, glad to see you found the cause of being unable to change that setting!

    Yes of course it will remove your overclock, you always need to re-tweak things with new BIOS as many changes are made with each BIOS revision. Same settings may not work either, you may need more or less of any one setting to gain stability again.

    I doubt it is caused by the card, but very well could be if your card is faulty or your power supply is not good enough. But I do lean more towards incorrect BIOS settings, please grab a template from my signature and give me your full specs and your current settings that are failing and I will advise back. Using Auto is often not going to work, and this confuses people. Auto settings are really only intended to work for the bare minimum such as 1-2GB of ram at slow speeds, or to get the board going so the user can get into the BIOS and make the necessary adjustments. Any board similar will be the same, as these are overclocker/enthusiast boards (Asus would be the same) you would need to find and set your own settings manually per your particular hardware.

    Plug and Play or boards that do work fully with any hardware are only cheap OEM boards such as Dell, HP, Ect where you do not have BIOS access and things are set very loose which causes great stability but also kills performance

    I can help with this for sure, so please get me your specs and settings and I will see if I can help you get going. Please do include a link to your ram or the model # as well.

    *edit*

    Sorry forgot to tell you, you can disable the floppy disk in the advanced BIOS page. Just remove it from the boot order

    Thanks. managed to disable floppy drive.

    The crashes are less frequent, but are still occuring.

    I think I'll just try and get the motherboard swapped out for a non Gigabyte board and see if that fixes it.

    Cheers.

    Glad to see you go it!

    Sounds like you need help with your settings to me, not a new board. Please give me your full specs and settings, template to do so is in my signature.

    Would be nice to know if its the store fault then (considering they put it together/setup BIOS). But im not sure..


    Anyway here is my full system specs and the template you asked for:

    CPU: i7 860 @ 2.8ghz (stock after BIOS flash).(Was running at diffrent voltages etc before I flashed the BIOS as the CPU was overclocked to 3.6GHZ)
    RAM: SuperTalent 4GB 1600
    GPU: ATI HD5870 (running Catalyst 9.11-newest).
    PSU: Corsair HX620

    I think thats specs you needed.

    It would not be there fault really, since you updated the BIOS it would require different settings.

    Try these for 3.6. Please also link me to your memory or give me the model # so I can check to see if you can use better timings then I am posting now

    Default Re: Flashing P55-UD4 BIOS

    Thanks for the effort man.

    Unfortuanatly I won't be able to change these settings and test them. PC is going back to the store I bought it from so they can fix it.

    Remember though, it was crashing before I did the BIOS flash, in fact the BIOS flash I did reduced the number of crashes, but its still there.

    TBH I don't care anymore. I go into AMD forums and read how other people have same mobo and gpu as me have exactly the same problem.

    Can't be coincidence. Will report back when I get my PC back to say what fixed the problem.

    Well good luck, it's all in the settings really. So if they do not adjust them for you the problems will remain likely.

    Let us know how you get along
