Sabertooth z77 UEFI sometimes is blurry and/or pixelated, blackscreens too.

Sabertooth z77 The UEFI sometimes is blurry and/or pixelated, also sometimes there screen is black and there's only the mouse cursor and the time widget. In those cases if I move the cursor it reveals more of the UEFI... It's hard to explain and it's also all pixelated and stuff. Im running the latest BIOS and it was happening on the older one's too. If I reboot again it works normal but alot of the tiomes on boot it does all the strange stuff. no matter HDMI or DVI.

  1. The asus bios has some quirks. Set the bios to standard mode. The performance mode changes ram to CPU timing and can cause issues. Make sure under ai tweeter xmp profile is turned on and the mb using that timing.
    If your using the onboard video make sure it set as the first video device.
    Under that if your not going to use a gpu turn off multi monitor and MVP chipset. Make sure the MVP software from the mb cd was not installed. It buggy it cause issue with onboard and gpu if you try to bond them. The newer paid software is more stable. With the ipgpu also try to set ram size larger or smaller and see if that helps.
  2. That is odd indeed I am running a Asus Z77 Sabertooth with the latest bios also but have not had any problems with the UEFI bios and am using performance mode and have since day one with no problems. I know that is not much help the best guess I would have is that there is something wrong with the UEFI BIOS on your board. If it is not to late already I would send it in for a RMA repair.
  3. With onboard video the issue won't be the mb. The chipset in the CPU.
    If it not a setting issue see if there thermal paste on the CPU pins or a bent pin.
  4. I agree, it's sounds like an issue with the iGPU in your Intel CPU.

    A few points:
    1) Any issues in Windows (or Memtest) or is it only the BIOS?

    2) Update your BIOS if out of date (though I doubt that's your issue).

    3) There's NO REASON to use your iGPU if you game (FYI, LucidLogix software is crap so avoid that completely. I tested it extensively.)

    Z77 Sabertooth SMALL FANS:
    *The small 30/40mm ASSIST FANS can be turned off completely. Download and Install the Asus Thermal Radar software (I don't recommend the entire suite) and there will be an option to turn off. I use 45degC. They basically never come on except for shutdown, but they could come on if my system overheated.

    These fans are buzzy, annoying things when not turned off.
  5. Phonton did you know under asus fan profile if you set those fans to manul you can have the mb spin them off if not needed. Mine only come one when the chipset gets hot.

    I did know. That's why I said the following:

    "...*The small 30/40mm ASSIST FANS can be turned off completely. Download and Install the Asus Thermal Radar software (I don't recommend the entire suite) and there will be an option to turn off.

    Next time, please actually READ a reply a little better before commenting on it.

    I am not using the igpu, i have 2 gtx 670 ftw edition from evga running in sli. I have issues in games too but its strange stuttering even when games are in high fps. i saw that cpu spikes but it passed all the syntetic benchmarks ex: prime 95... Im not sure what to do. I think the issue is not the CPU but the mobo because of the messed up UEFI, and that I had issues with changeing settings in UEFI and having no effect in windows ex: overclocking the cpu. All this happans no metter if the hardware is overclocked or not I tried changing all the variables but no matter what setting and what I do I still get glitches... I RMAed the graphics card and it was not the issue and have tested the cpu and ram so the only place there could be an issue is the mobo.
  8. Check that the CPU cooler not crushing the CPU. Newer ib there top cases are weak. Check to see if any thermal paste got onto the up pins. The z77 mb do have a multiplex chip for the video lanes. If the chip has an issue try in the bios to set the pci video speed from pci 3.0 mode to the older 2.0 mode and see if the error changes.
