GA-945P DS3 and XFX HD 4770

[DeniZz]

Hi, guys. I know my mobo (GA-945P DS3) is very old, but I love it - or, better say, that I loved it, before replaced video card from GF8600 to HD4770. Now I unable to overclock things, that I've usually overclocked. And that post delay is annoying me (15-20 sec. before first beep). Bios is lattest (F6i) but it hasn't support for my video card.
Is there any way to make my modo and video to be friends?..

(Sorry for my english)

Hi and welcome to the Gigabyte Forum.

I would suggest that you clear your CMOS as a first resort. Also have you made sure that you have cleaned your old drivers form the system before installing the new ones ?

Remove the power cable from the mains supply and then press the power switch on the case for a few seconds just to drain any residual energy in the PSU capacitors.

Once done remove the motherboard battery for at least one hour before replacing it.
 
Next plug back into the mains supply and boot.
 
You will now need to enter the BIOS by pressing DEL and load Optimised BIOS Defaults.

Make any other changes to the BIOS settings to suit your self like disabling the floppy drive, disabling the full screen logo and making the HDD the primary boot device and then press F10 to save and exit.

With drivers there is no problems, reinstalled system several times and all drivers is the latest ones. But how does they can affect bios?..
I just can't overclock anymore, cuz bios resets all changes after reboot - not all, but needed for overclock (FSB, PCI-E, Memory clocks...). I also know, that my mobo is bad for overclocking, cuz it automatically raises PCI-E frequency and it can't be locked for better OC (CPU Core 2 Duo 6320). With old video card it was stable at CPU Host Freq. = 320 (default is 266), but now I can't change it even to 267. So I played with bios very long time - nothing helps. But thanks for your advise, I'll try everything that you posted, and I'll say if anything changes.

Hi again. So I tried clearing CMOS, removing battery and etc. Nothing helps. Also I found many threads on other forums with similar problems (long boot delay with old mobos and new ati videos). The only fix for this is updating bios or upgrading motherboard.
So, maybe there is somewhere super-secret labs with alpha-beta versions of up-to-date bioses for old gigabyte motherboards? )) ...

Have you checked on the download section of the website ?

If you have no luck there try TweakTown Forums in the US as they tend to have an archive of old BIOS versions.
