GPU making too much noise after OC

I oc'ed my gpu a few days back. Now my cabby is making too much noise.
I restored the clock settings to default but still the noise is there. And FAN also set to Auto.

I oced my gpu from
Core Clock: 875 mhz to 900mhz
Memory Clock: 1200mhz to 1355mhz

GPU Z Temp
*gpuz.techpowerup.com/11/03/26/6v6.png

My rig
HD5770
C2Q6600
Mobo : Intel DG33Bu (uber suck)
3 * 1 GB XMS2

How can i fix this?

Are you sure the OC has been removed. Stress the card and check the clocks.

How do I do that?

BTW I used MSI Afterburn for OC'ing.

Errm...stress the card using the MSI Afterburn Fur utility, and see what the clocks show on GPU-Z.

To be frank, that was the 1st time i OC'ed. So please forgive me for being n00ish.

I will do the furmark test and report back asap.

EDIT:-
I downloaded FurMark 1.9.0 and these are the results

Jojo you did not get me. I meant CHECK if your card is still moving to OC clocks when stressed.

How do you do that. Run a stress 3D utility and check the clock on GPU-Z. Are they default or OC'ed..?

You result shows that yes the have been defaulted. Now the fan noise is weird. You sure it is coming from the GPU.

@jojo, which brand GPU are you using?

@ jojo

3dmark should do the job for you. Do what asingh said. Don't try msi kombustor. It has issues with amd 5 series gpu's.

I just don;t know, i thought the FurMark utility should do the job.

Or did you mean the "Burn-in" thingy?

Ok i'll download the 3dMark 11 Basic and then post results.

Sorry about the bump.

The issue was still there until today.

I pressed my ear against the cabby and found out that the culprit was the PSU. So I opened it up, cleaned up the dirt and voila! The sound it no more. The cabby is running silently now.
