The motherboard is still in a boot loop, and it won't even allow me to get to the BIOS settings.  The MB codes cycle from F3-F6-F3-68 and the system turns itself off and repeats the same cycle of codes.  Each cycle takes less than five seconds.  So far, I have replaced the power supply with a brand new EVGA 1300 Watt PSU, but the same problem remains.  I have pulled out all of the RAM DIMMs and then just installed one DIMM into DIMM Slot #1.  I have tried each RAM DIMM in slot one, but the same results.  I have tried using a completely different set of RAM from a different manufacturer, but the same problem persists.  I have removed all of the HDDs, USB ports, and even the cooling fans to reduce the config to a bare minimum, but the problem still persists.  I have also removed and reseated the processor, but the problem still persists.  I have removed the MB from the computer case and run the MB on cardboard, outside of the computer case, but the same problem persists.  I don't know what else to try here.  Please advise.

    So can we assume you have pulled out the cmos battery and reset the cmos? If so try 1 ram in different dimm slots.

    F3 is not seeing the first memory bank, F6 the second, check that your cooler is not too tight, that there is no FOD in the memory slots, and that you did not bend a cpu pin, Too much presure on the cooler can cause this, as it cocks the cpu and prevents pin contact.

    I have same problem. After power off computer on PSU (all LEDs are off) it's starting. But after reset, or power off (soft) it's constantly reset at 68.
    Mobo is EVGA Classified E760.
    I change RAM, PSU, GFX, HDD, CPU, cooling ......  just all.

    Ok so this is what I want you to do. Pull everything from the board(CpU, ram, CMoS battery). And leave it overnight. In the morning come back and put it together again. See if it still boot loops

    I have the same problem here. I have had my x58 le sli running since 2009 with only a graphics card replacement.  From the research I've done and continue to do it seems to be a common problem with these boards and they are just starting to fail.  I am in the process of trying to figure out what replacement board to get.  Let us know if anything helps but from what I've read people have changed out everything without much luck,

    If your motherboards are within warranty then please submit an RMA

    try restarting without any hdd's or ssd's connected. If that works enter bios and re enter your settings before restarting with your drives plugged back in

    Not sure what the rules are, but I have the same issue, been getting BSOD's lately, I've had freezing screens a lot in the past few weeks and sometimes the PC will not respond to reset button or power shut down button on the FRONT of the PC case, where I would have to hard shut down the PC via the powersupply...It froze the other day and has been in a reboot loop ever since.. I tried resetting the CMOS but that just made it do a faster reboot, never gets to BIOS screen.. only change is the new GTX 680 about a year ago, other-wise the build has been running pretty good since 2009. I do have the A1 version of the 3x SLI MB.. but I moved to Texas from Michigan and I won't likely be able to find the invoice anytime soon as I have stuff in storage, etc..  don't want to send in the board if it's not the board.. tried moving ram to various slots and using various sticks no change.. pulled cpu & cooler, no change... should I RMA or pay $ for a Power Supply Test?  I bought my Board from Newegg.com

    Hi (sorry for my english),
     
    i had the same problem. My mb booted loop every time and the last mb code was 68.
     
    I solved this issue with disconnecting the two 6 pins pcie wire from psu on my 8800gtx (still works fine ^^) and the 8 pins wire for processor.
    i boot without this 3 wire and the mobo display FF code and my video cards whistled.
    After, i repluged all wire and the pc started fine ..... after i updated my bios to version 83 and it still works since 2 weeks.
     
    hope it can help

    I'm very disappointed to report I'm now suffering a similar boot loop issue. although my system is throwing up only F3/F6
    however it does not always reboot it just sits there and waits fro the rest of the post gear to happen which of course doesn't and it just sits there apparently hanging.... when it does that it seems to display a code 08/80 not sure which.

    this has only happened suddenly too. has been working perfectly up until now...

    I have the same issue - just recently happened. Unfortunately, the board is out of warranty and I am not in a position to build a new system. I am seriously considering selling off all the parts and calling it a day. Very depressed about this - was such a good system for many years.
     Let us have a moment of silence for my dear departed system {insert TAPS here}

    It has been my experience that the f3 f6 boot loop is related to memory.  Please remove all memory sticks from the motherboard and power it on.  It should give you an error code of 7F.  This would be normal.  If you still get the f3 f6 loop with no Ram installed then it is likely a memory controller issue.  The memory controller for all X58 motherboards is in the CPU.  If you get the 7F code then it is a memory issue and you need to test each stick of ram individually.  You may also want to try setting your ram timings in the bios to what your ram manufacturer recommends.

    I had this problem on a computer I have been using a couple years. Everything was working fine, then one day turn it and got F3 F6 F3 F6 68 pause 69 then reboot loop. Long story short, removed all ram got F3 F6 F3 F6 flashed 62 and reboot. I did try re-seating the CPU. A friend had an I7-920 I borrowed to test the motherboard. It was the CPU in the end.

    I too have joined this club with my x58, this afternoon playing on it and it just reset, then would not boot giving the F3 F6 then a few more codes then 7F.
     
    I have opened a support ticket with a EVGA tech and am working it, but I'd like anyone here to watch this boot and give me their thoughts as well, I videoed it booting before troubleshooting and uploaded that to my own website:
     
    http://www.dynamicflight.com/dl/EVGA Boot Up.mp4
     
    It's somewhat bittersweet, I just got the system upgraded to win 10 and it was humming along nicely, I'd had no issues with it for 6 years.
    If indeed the processor, I may get a refurb i7-950 instead of a 920 to allow me to run it without OC'ing. (my OC was very mild as well, nothing that I believe would have contributed to it, I only say that because it was in that config for 6 years, and had been cleaned out every quarter, no dust on anything ...
     
    I appreciate any responses beforehand, thanks.

    yes, being a 980x it was only a light OC to 4ghz.

    was having the same problem, turned out one of the diodes in the memory circuit had exploded. remove the motherboard from the case and closely inspect diodes D13-D18 and i believe you will find the culprit.

    Awesome find! Were you able to repair this? Do you mind attaching a picture that's more zoomed-out so I can see where on the board it is? I'm having trouble finding these on mine (I can only find D12, and it doesn't look blown).
     
    If it is a matter of blown diodes, does anyone know how to determine the details of these surface-mount diodes in order to find replacements? I realize it's surface-mount, so it wouldn't be the easiest to solder.

    Awesome find! Were you able to repair this? Do you mind attaching a picture that's more zoomed-out so I can see where on the board it is? I'm having trouble finding these on mine (I can only find D12, and it doesn't look blown).
     
    If it is a matter of blown diodes, does anyone know how to determine the details of these surface-mount diodes in order to find replacements? I realize it's surface-mount, so it wouldn't be the easiest to solder.




    Upon further inspection of my old pic added with another year of circuit level repair experience, that's surely a smd mosfet that let the schmoo out. I just chunked the board and upgraded to a skylake at the time. I went through my old pics and i didn't really take an overview picture, but it's probably a good idea to just check the whole board over, then throw it away and buy a new computer.
