    barcode,

    I feel your pain I really do. I went out and bought a new board (this will be my third now this year, the EVGA frist which died then the GA P35 DS4 which also died).

    I have not seen any suggested solution to this from Gigabyte and indeed support (I initially contacted then before I found this board and posted here) told me to reset CMOS and if that fails sent the board to them! I guess that is the final answer on this.

    Cheers and best of luck with your board. My new one is working but I am not able to get the DVD drive to work in VISTA even though it appears in the BIOS.. again... that issue is for another board!!

    hehe, thanks for your empathy

    unfortunately the EVGA 780i is on backorder - i guess they have had problems because Intel did not communicate properly to nvidia what changes the penryn cores will bring.

    i am currently not sure if i should try once ASUS again - perhapps the "maximus formula" or the "p5e3" - p5k has a vcore drop that is too high...

    i red good things about the Foxconn "Mars" IP35 but there we are again at the IP35 Chipset - on the other hand no users complain in the threads about that board.. and foxconn seems to be a new manufacturer on the market and will pay attention to gain a good reputation at the users (which btw. gigabyte is loosing when they have to make 3 attempts to get a mobo stable / rev 1.0, rev 1.1 and finally rev 2.0 - which is still not fixed obviously)

    you know it is not actually the money that i loose that angers me ... it's my lifetime that i waste with that crap... i could do other things meanwhile instead of this - if you know what i mean, i could be already working with a stable running system if i've had made the right choice...

    I have this board, and the BIOS (doesn't matter which BIOS revision you're running) doesn't properly detect optimum memory voltage when set to auto.

    The board will run the memory at 1.8v in Auto no matter what.

    A lot of the higher performance memory right now is running at ~2.2v. What I recommend is to go into the BIOS and manually set the voltage gain on the memory. This board's reference voltage for memory is 1.8v, so if you are running 2.2v memory, then you need to set for a +0.4v gain in the BIOS. Not sure why Gigabyte can't get their BIOS to properly detect memory voltage. I am running memory that is listed in its supported memory list too.

    If your board is not running memory at its proper voltage, it will endlessly try to post, rebooting over and over. Clearing the CMOS by unplugging the machine, then yanking the CMOS battery for a few minutes, then put it back in, should allow the board to post and allow you to get into the BIOS to make the needed adjustments.

    Good luck!

    I notice the Chinese woman stopped answering you way back on page one. Not a good sign. I just bought this board at Newegg and I'm hoping I don't run into the same issues as you guys. tigerspy, thanks for the tip. I will add that to my growing list.

    +.4 resulted in a consistant 2.26v for me. + .3 results in a consistant 2.16v. A lot of performance ram will work at advertised timings well under the listed 2.2v...even the standard 1.8v in some cases. Even if you didnt want to take the time to see how low you can go and stay stable, I think +.3 is a better option and being a hair under rather then .4 and being a bit over if these boards tend to overvolt it a bit on its own.

    i bought this board and had the same problem, rma'd it and the new one worked, then i swapped cpu's with another mb, and when i put it back in the GA-P35-DS4 Rev. 2.0 endless boot, well i then swapped back to the other mb that it worked on a few min before, same thing on that board, never had problems with that board, anyway long story short, some of the fasteners on the heatsink were broken so i help it on the firmly, and bam. it worked, both boards booted, so your problem might be in your heatsink, perhaps a failsafe?

    The same issue with the same MB. Only difference is, that I updated the BIOS under Qflash. And I didn’t even see the “BIOS recovery” on my screen. I can imagine getting a bad BIOS, however from the official site, but the thing is this MB should have 2 BIOSes just for cases like this. Is there a way how to get to the second BIOS?
    I tried all like mgreen481 (same Google results:)), accept to buy a new MB. I hope this is not the only way as I bought mine abroad.
    Gigabyte, where are you?

    Have you unplugged the power supply from the wall and put a hard drive or optical jumper on the clear CMOS pins for 10 minutes, then remove the jumper and plug your board back in?

    If not try that, otherwise here is a very in depth method to blind flash that may or may not work, if it does not then you will need to RMA

    After this thread scared the crap out of me with my own endless rebooting issue, I thought I'd post the solution I found which, so far, seems to be working. It might help someone else.

    In my case, the rebooting issue surfaced after I'd switched out a built-in usb card reader. I installed the new reader, and instantly had the rebooting problem. I hadn't had any problems with this mb in the five months I've been using it.

    Once I realized I was dealing with a mb issue, from this thread and other Gigabyte threads, one idea I read about was removing the bios button battery on the mb. I took it out, tested it to make sure it wasn't dead, and then replaced it. I wasn't expected much -- but it worked.

    The next time I pressed the on/off switch, I actually got to a message on the monitor. I was so shocked, I didn't catch everything it said, but it was something along the lines of 'use last known good configuration'. Since I use a wireless keyboard, I couldn't do anything anyway, so I just let it run.

    The final result: everything is back to normal. No side effects, no issues. So far. (I'm not sure whether my bios settings were restored to the way I had them or not. I've forgotten how I set them up originally, but everything seems to be working - so I'm just going to leave them as-is for now.)

    Anyway, hope this helps someone in the future.

    And, thanks to everyone who posted with ideas about how to solve the problem. Otherwise, I would have had no idea what I was dealing with.
