p35 ds3r after overclocking monitor goes off

p35 ds3r (bios f11) after overclocking monitor sometimes goes off. Probably there is problem with motherboard because everything is working (video, sound) just monitor calls that there is no signal and I have to restart.

Please have you any idea what can cause this?

thx

  1. Did you forget to lock PCIE at 100mhz? Otherwise it goes up with fsb and graphics card get burned.

    of course I locked it.....even I set there less then 100 MHz. GPU clock is still the same. Of course prime 95 was successful...even increasing voltage didnt help
  3. Less than 100MHz is not good, you need to set it to exactly 100MHz.

    If that's not it, you'll need to post all the model numbers of all your components, including MB, CPU, CPU cooler, drives, power supply, graphics card, etc, and list the settings that cause the problem, and those that don't.

  5. Im not 100% on this but PSU may be under powered if it's 380W. (I realize SeaSonic is a good brand, but to me 380W seems too low)
  6. Ok. I ran a PSU watt calc here: http://extreme.outervision.com/PSUEngine
    for your system. I got about 340W (assumed DVD RW,fans and other standard stuff) to me that's probably cutting it too close.

    no, for sure it is not under powered......it does even in idle regime. Or try to count consumption, it is OK. And as I said...it does only overclocked without changing voltage

    I calculated 294 W even overclocked with fans, usb and 100 % system load
  9. Hm... These are the settings I used:

    High end motherboard
    HD2600 Pro 512MB
    3 LED Fans
    4 DDR2 RAM
    ant the usual rest.
  10. its most likely PSU is underpower.a system got a dual core and 2 sticks orf ram and a mid-high graphics card with 3 hard drives will most likely to need at least 350W.and PSU doesnt supply the stated power figure.

    so 380W PSU-10%=about 350W.plus if you overclock,even you didnt overvolt there will be more voltage pumping through the MOSFET and various parts on the mobo.plus fluctuation in all the component CPU,RAM,Graphics card and even the PSU itself suffer from such problem.

    get a 500W PSU to test it see if its still happen.But i have experienced before this could be due to the motherboard's problem as its not sending an ON signal to the video card.
  11. ms - thanks for the very nice list!

    The total PS wattage doesn't matter, rather, the +12V supply is what matters. It looks like this PS gives 27A max of +12V, which may or may not be enough under high-current-draw conditions (such as overclocking). So, it might be the PS.
    Also, have you tried monitoring CPU, GPU, and general system temps? More likely than the PS is that perhaps the GPU is overheating? If this is the correct video card you have: http://www.newegg.com/Product/Product.aspx?Item=N82E16814127300
    then it could certainly be overheating under OC conditions if you don't have enough airflow in your case to (a) exhaust enough hot air from your case and (b) blow enough air over the heatsink of the video card. Especially with all that stuff (hard drives, extra tuners, etc) in your case, unless you have at least 2-3 120mm exhaust fans, I bet it gets pretty toasty inside that case.
    On a related note, since you are using a CPU cooler that does not perform the secondary cooling of nearby components (e.g. north bridge and PWM area) that the stock Intel cooler does, you could be seeing problems due to northbridge and/or PWM area overheating.

    Finally, is your MB one of the Gigabyte boards with their new "energy saving" features? If so, I've seen a number of posts that the technology doesn't work right yet, and instead causes crashes.

    of course, temperatures were OK (not more than 60 due to ati tools)....I have 2 exhausting fans near graphic card (and one 120 mm inrushing fan before HDDs + 120 mm PSU fan)

    yes, exactly this GPU I have

    yes, but I dont use this "energy saving" feature.

    so just presume that PSU is OK (it happens when Im just surfing on internet).....what about some bios setting, can be any problem there? I just changed FSB onto 400 MHz (from 333MHz, for 1600 MHz is MB ready) and set PCIE to 100 MHz
  13. ^You need to have SPD at 2 to run at FSB 400.
  14. i think it would be better to start your oc again since you dont know where you are at.

    try put excess volt on all part except ram no more then 2.1V.some can run on 2.2v but in general 2.1v is the max safe volt.so your component is not short of juice and just freeze itself.
  15. of course, I forgot.....My RAMs have always been running at 800 MHz (not any voltage change hasnt helped
  16. probably I need to remind......everything is working, just monitor has suddenly no signal
  17. ^Ok, now this seems to be like the following problems:

    Graphic card is bad
    PSU is under powered
    Motherboard is bad.

    Also did you try increasing PCIe voltage?

    1) Im going to buy newone anyway....just waiting for HD4650 so we will see
    2) probably not....I havent used 100 % (also not any 50 %) system load when it has happened
    3) yes....I think so....but what?? Ive tried to set PCIE 101 MHz... so Im waiting for results

    4) ok, I ll try it
  19. I have a question if your mobo work with BIOSRecovery express and resume the video output after setting recovery? It should be automatically run for Gigabyte mobo whenever your new setting that is not available to work properly, if the BIOSrecovered and still no display you may put your display card in another motherboard to see if the display card unfortunately failed.

    After setting recovery??? I just restart PC....it helps.....and to remind.....PC is still working normally, there is just no signal for monitor

    when I have possibility I ll try to put my graphic card into another MB
  21. so probably it was my fault.....Ive set much more voltage up to my processor (1,3 V) and problem is for the time beeing out....but still a little strange...just picture had been disappearing before
  22. so no.....again it has happened
  23. put it back on stock for everything then start again.

    or it could be a defective mobo or graphics card.
  24. It could also be refresh rate. If refresh rate is some how effected by the Ocing that might be a cause. It could also be the card itself.

    Is the BIOS setting restore to last available setting by press [F9] during the Gigabyte Logo Screen? If still nothing display, you may try to clear the CMOS setting to let it automatically restore to factory setting. 2 Days before when I set BIOS for overclocking I wrongly set my CPU voltage for 1.18V and resulted display go off and the XpressRecovery function also not applicable so I was forced to remove the Battery and clear the CMOS setting by connected the Jump for CMOS clear. After that everything become normal again. Even my mobo is GA-X48-DS5 that is not same as yours however I think the handling on BIOS setting would be identical. Let's try it.
