Should I be concerned(3770k with Sabertooth Z77)?

post #1 of 6
Thread Starter 
I was stress testing and oc'ing my computer today and got it to 4.5(which I've always been able to, just never messed with the vcore until today), I then decided to try for 4.7(the highest I could ever safely go, again without touching the vcore). Rebooted into BIOS, changed the multiplier to 47, hit save and reset, booted up fine, but it still read 4.5 in CPUZ. I tried again(it saved the multiplier as 47 in the bios) and still 4.5 in CPUZ. Read the Ivy Bridge ASUS guide here, changed all the settings to match...still 4.5. I load ASUS' AI Suite, it's set to 45, change it to 46 and CPUZ is now showing 4.6. Should I just reflash the BIOS? I am running 1805(the latest). No other issues that I can tell.

Don't worry you just have the Asus bios bug. Everyone has been getting it when testing out new overclocks. You just need to reflash bios.

If you have any settings in bios that do not carry through, get stuck, or seem to change on their own then you have encountered the bug. Just reflash bios and you will be good, well good until you eventually encounter it again.

Download the bios file, use the renamer utility to name it correctly, and place the renamed file on a fat32 USB stick. Shut your machine down, but leave the power plugged in. Place the USB stick in your designated flashback usb port then hold the flashback button for three seconds until the light starts blinking. Wait a few minutes for it to finish.

Start the machine up and you are good to go. Before doing this, export your saved profiles to the usb stick because you will lose all your settings and profiles. Once the procedure is done you can reload your saved profiles from the usb. The saved profiles will work as long as you are reflashing the same bios version.

You will be able to make several changes to bios before encountering the bug again. It all depends on how much instability you create. A way to minimize that is work backwards with your vCore instead of upwards when testing. Eventually when the bug pops up again, just follow the reflash instructions again.

By the way make sure to check out this thread for the best oc advice on Asus mobos:

Thanks man:thumb:

That's actually the guide that I was using after I started encountering this issue.

I guess it's time for me to buy a flash drive, ha.

Me too gets this issue sometimes on Asus p8z77-V Deluxe but for me a quick reset of the bios helps. Sometimes I need to do it twice.

I have had that bug as well a couple times, very rare but does happen. I just reflash the bios in the asus ai utility and that works as well.

Yep, get a thumb drive, format fat32. Put the renamed bios file on it, and you can use the same one to export your saved profiles and any bios screen shots you want. I have lost track of how many times I had to reflash while ocing a few chips lately. Asus is working on a new bios to address the bug, should be out soon.
