    Default GA-P35-DS3R v1.0 won't hold overclock at all

    After 3 months of having a RMA'd board, my mobo will no longer hold overclocked settings at all, hot or cold. It will retain all settings except for the overclocking settings that are known stable settings I've used for the last 6 months. I have also tried bumping up the FSB from stock in 1mhz increments and it will not even allow that. I see many people have this same problem with similar boards and am wondering if anyone has figured out a fix to this completely erratic behavior. Also, please spare me any intuitive suggestions about component incompatibility, I've had this same setup running on my first board then this RMA'd one for over a year and a half completely stable :O

    That's the same problem I'm having / have had.

    In order to enable it to overclcok again, remove the cmos battery and the mains lead from the PSU, leave it overnight then the board will hold an overclock again.

    That works for me and others I've seen with the same problem

    It's incredibly frustrating to be told that the components are incompatible when it's been working perfectly for quite some time, and I'm no closer to finding out WHY it happens, or a means to stop it happening again, I'm pretty sure it's a BIOS issue though.

    Absolutely frustrating as if they didn't hear the board was running fine for quite some time.

    I have seen this problem fixed by an updated BIOS but for newer boards that have not been running for a while.

    Have you checked your memory with Memtest??? The memory could be dying.


    Memtest86+ (Memory Testing)

    Memtest86+ - Advanced Memory Diagnostic Tool Download


    When doing basic tests on new ram or just for general testing purposes you should let the test run on it's own for a few hours up to 24 if you have the time and don't mind.

    When you are tweaking timings and just need some quick answers you can quickly see if your recent changes have made your ram unstable by choosing certain tests. Some say their own set of test #'s to use and they may differ from my own, so if you see someone else suggesting test #'s they that would be fine as well to, it is up to you.

    What test #'s I use for basic speed testing to see if recent changes are causing errors quickly are #'s 2 & 5. I run test #2 for about 10 minutes and if I see no errors I will then run test #5 for a hour or so. If no errors are found then your changes are likely ok for the time being. Longer tests will let you know for sure though, but like I said here we are speed testing while doing a little bit of tweaking. If it is going to fail you think and are not so sure let #5 run for a while. It will fail on #5 if it is going to fail.
    Try the last paragraph.

    Yes, I would suggest to both users above to test their ram at stock speeds, timings, and voltages manually set, one stick at a time with Memtest86+ 2.01 linked above (Older versions not compatible with P35)

    Once you are sure all your ram is not DOA or dying, please post back with full specs, like 2x1 or 2x2 ram and such. Most of the time things like this can be solved with a CPU re-seat or a Newer BIOS

    If either of you would like, feel free to post me your settings, and I will see if I see anything out of the ordinary >>>

    Hmm, Well Auto is generally no help in performance, and often can hinder Stability. Can you post a MemSet screenshot so I can see what you are getting in windows for all those Auto settings? MemSet linked in this thread>>>

    Do you have Legacy USB Storage Detect Enabled? If so disable it, it is in Integrated Peripherals page.

    How long has it been since you have reseated your CPU and loaded optimized defaults? Just wondering

    To the OP - It is VERY frustrating when the motherboard will not accept even a 1mhz increase. For me removing the lead from the PSU and placing a jumper over the CMOS pins for 10 minutes has resolved it. When I replaced the lead and removed the jumper I then went into the BIOS and pressed F12, IIRC, and loaded my known stable overclocked settings.

    Then it was fine.

    Maybe I'm wrong here but I'm not sure if it has anything to do with the overclocked settings being too high, as it would then be expected to set at a lower speed and then allow access to the BIOS. Also it could be simply a setting too many as this has happened to me when I have gone in the BIOS and say altered the boot order for my hard drive and bingo the moderate overclocked settings are gone.
    My PC has looped memtest and Orthos etc etc so stability is fine.

    BTW - When I have saved a setting in the BIOS which has subsequently lead to the overclocked setting being ignored, even though they are there when I look in the BIOS screen again, there is never anything more than a single boot - no double or triple booting.

    My board is a P35c DS3r rev 2.0 F11 BIOS

    Yeah, IMHO there's a problem with the BIOS on the GA-P35DS3x series of boards, a number of people seem to be affected by this issue, and the fix always seem to be the same, clear CMOS completely, then go revert to overclocked settings.

    It's strange, it's happened to me a few times now and I'm no closer to knowing why!

    Legacy USB storage Detect Disabled? And no External USB devices connected?

    Why should that be a potential problem - are you serious no USB devices connected. ..?!!! Come on, there are 8 USB ports on the back and all of mine are full. I will not be removing every USB device, if that is what you are suggesting, just to see if my once in every so often b0rked BIOS savings don't happen..!

    I've stood on one leg and spun round in a circle chanting a mantra or something and it still makes no difference.
    A board will do what a board will do...

    Seriously though for me it is no major issue, I posted about this months ago, as long as the boards dementia resolves itself with a 10 minute cooling off period. I use that time to go and make a cup of tea
