I enabled XMP profile one on the second bios slot and now it cycles to code 23 and stops. I am using bios 104

Tried to enable XMP 1 on bios three with the original bios and it does the same. Cycles to code 23 over and over.

Bios slot one is 104 beta and it works fine


So, I tried to reset the CMOS toggled to position 2 and 3 and it still cycles to code 23 (IMC won't run at that frequency). I tried turning off the power switch, taking out the CMOS battery and discharging the board by hitting the power button and coming back in ten minutes and putting the battery back in. Both 2 and 3 bios slots still cycle to 23. have I corrupted bios 2 an 3 by enabling the memory XMP profile?

I've also tried to remove all the memory and tried one dimm in each slot and it still cycles to 23 over and over.

This may be something only Jacob can answer

    Ok I fixed it. Instead of just hitting CMOS button, I held it down for a 20 count and it reset.

    In case any of you have problems like this by enabling XMP memory profiles, hold down the CMOS for 20 seconds.

    You can reflash BIOS 2. Just boot with BIOS 1, then flip the jumper right before BIOS starts to flash.
     
    Secondly what memory are you using? You are using 4 DIMM's right? If so you may not be able to use XMP as this was primarily tuned for 2, you can try setting memory clock manually and leave other timings at auto.

    G skill 2666 4x4. Glad there is a bios flash solution and I will steer clear of the XMP profiles. Thank you

    That worked. Thank you thank you. Good info to know that you can boot with one bios then switch to the other right before you hit shift Y

    I would highly recommend those of you that are tweaking to set up a USB Flash boot and bios files loaded for times like this. If you don't have immediate access to another computer

    wow! that's a solid solution for flashing a corrupted BIOS! Jacob, you should be awarded with a BR, I bet not many people actually knows (myself included until now) that one can flip the BIOS switch when in Windows and flash it this way!

    Yeah, I was glad to see this and this pearl needs to be put some place. So essentially, you can flash any bios you want jut by changing the toggle to the respective bios prior to hitting shift Y to proceed.

    Sorry you've had bad luck, at least a solution was possible.  I had already planned never to update bios 3 or access it unless I blew up 1 + 2 somehow.  A permanent fallback imo.  (going to leave it on the shipped bios revision.

    Yes, lately, If I can find a problem I do or it finds me.  Part of the game when learning a new board.
