p67-ud4-b3 bios issue

[burningforce]

hey all

when I got my new computer built and working a few months ago, it was running smoothly. Then I started to mess with overclocking and results where not up to par with what I was seeing with everyone that posted their results in tech forums.

I decided to flash the bios to a newer version, it was successful and I made sure to load "optimized defaults" after the flash as gigabyte says to do. But I did not know I was supposed to use @bios first, flash it, reset and load optimized defaults, then shutdown and clear cmos for a few minutes.

So now my performance is somewhat bad now. whenever I watch a video on my secondary monitor and it switches to a new video, there is some lag until the video is fully loaded. This is not just wow specific and happens when I am even browsing the web. I ran with the bare minimum hardware, ran HDD diagnostics software on each drive, and tested all parts minus motherboard + cpu + memory in another computer and all seemed to work.

I sent the motherboard to gigabyte and they just said to clear cmos and sent it back, I cleared cmos for around 20 minutes with the power unplugged and stilll having the same problems with performance. So I am not sure if it is just wrong settings in the bios, damaged cpu or damaged motherboard, or 2 bios versions overlapping each other giving the wrong settings.

here is my computer part list

cpu : i5 2500K @stock
motherboard : gigabyte P67-UD4-B3 @bios F4
psu : corsair hx750w
memory : gskill 1600 8GB ripjawsx
video card : gigabyte 6950 2GB with catalyst 11.7
1x western digital HD
1x intel SSD 40GB-V
1x samsung spinright F4 firmware patched

also I noticed when the multiplier is set to default of x33, when booting the hardware screen says the cpu multiplier is @x34 3.40Ghz. This is why I think the BIOS is messed up.

is there a certain way to clear ALL settings from the bios and backup bios on gigabyte boards? is there certain settings I need to turn on/off in the bios to have decent performance? Also is there a site that explains what most if not ll of the settings in the bios is and if I should turn them on/off? the manual does not go into detail for a lot of the settings and I never heard of these settings.

thanks for the help

As far as I know... flashing a BIOS has 2 results: It either works or it doesn't. I'm not 100% sure but, I
don't think a BIOS can sorta flash and then some things are 'messed up.' If things were messed up during
the flash your system would fail to POST. If it is indeed possible to half flash a BIOS and yours is messed
up, what is stopping you from re-flashing it using the correct procedure this time?

Any video that is on the screen is handled by the GPU, if you have a spare GPU to test with I would try that.
Could also be your Power Management settings are affecting this as well. Another option, while tedious, is to
try reinstalling Windows again fresh. Also, don't let Windows Update update your drivers.

I've seen this before on another P67 board and I don't think I'd worry about it. Download CPU-Z and
whatever it's reporting in there is what your CPU is running at.

Gigabyte boards sport their DualBIOS feature. Did you flash both chips? You should have a backup chip on
that board.

As for what you should turn off is up to you and your needs. For instance, if you're not using the Marvell
SATA ports on your board go ahead and turn them off. If you've got a sound card installed and you're not
using the onboard sound chip... shut it off.
