[FIXED for now] bout to give up overclocking (BIOS CHECKSUM ERROR)

post #1 of 16
Thread Starter 
Sig rig.

Everytime I use the brand new @BIOS to flash to ANY BIOS version (just tried F6, and have tried F5 and F6A) it does the same thing.

On reboot after flash (everything stock settings).

Power cycles, then it freezes at BIOS, power cycles again.

Set things where I want, acts like normal.

On the next reboot, it power cycles 2 times, then it gives a BIOS CHECKSUM ERROR and reflashes back to F2 BIOS with entire BIOS reset.

makes overclocking impossible.

Tried this 3-4 times now.

are you tweaking the new flash BEFORE allowing it to first boot? I would think you need to change a few settings pertinent to your rig. Are you sure your using the correct BIOS updates ?

"set things where I want, acts like normal" ----if you are overclocking.. back it off some. I dont thing its flashing back to factory bios.... rather its loading fail safe defaults.

So how do I set F6 bios as the "safe default" so when it loads that it doesnt reflash to F2.

And yes, it says "Flashing to BIOS backup F2... 4231kb" then it reboots with the F2 BIOS instead of F6 or w/e.

@BIOS reports it is the latest version.

Why on earth are you using @bios?

Be a man and do it from USB / Floppy!

See if it works then.

FLash to the latest (F6) And before first boot, set Bios according to needs for your hardware.. such as raid array, SSD settings... let it boot (do not overclock anything at this point)

Go back into bios, make sure your ram is set to correct settings. , let it boot.

Your old overclock may not work exactly the same as it did previously per Gigabytes site (2.Support "Internal CPU PLL Overvoltage") is displayed on this bios update.

You will most likely need to work your way to a new overclock.




why exactly are you flashing the bios? is there an update you need in there ?

Currently don't have a USB or Floppy.

@BIOS flashes it just fine, its just if I try to OC any at all.

I am taking pics, brb.

holy cow! I assumed you were using a bootable USB. Yes dont lazy way your way out of it ... do it right. copy the file to a clean bootable usb and do it that way before proceeding.

You WILL NOT be able to just plop in your old OC settings. You will have to "re overclock" from this point. That is your issue.

seriously tho... go buy you a USB stick... @bios has issues and should not be trusted even if you "think" its working.

Before flashing you should load BIOS defaults and reboot. After flashing you should clear CMOS just to be safe.

Then like TDS said, you'll manually go through all the settings and maybe retune a bit.

Ok so I think you did help me out tho.

I used to keep flashing the BIOS when overclocked, I guess that was no no.

But I fixed that before I came to this thread

But I did stop OC'ing before the 1st reboot. (IE. I just changed what I had to like IDE -> ACHI).

And that seems to fix the problem, I have had like 4 failed boots but no auto reflashing to F2 or checksum error.

So for the time being, I am going to rule this one fixed.

Quote:
Steps I took:

0. RESET BIOS to stock settings (Load Safe Defaults)!!!
1. Download latest @BIOS, and latest BIOS version (F6 for me).
2. Don't do anything in @BIOS but flash to BIOS on file (and just look for the BIOS file).
3. Restart like it says. Enter BIOS.
4. DO NOT attempt to OC, just change what you need such as IDE to ACHI in-order to boot properly.
5. Then once into the OS, just restart again and then you can try and OC all you want.
