Overclocking/Underclocking Video Cards

On the topic of overclocking the 6800 GT, anyone out there ever heard of support staff actually being able to test a card to see if its core clock has been changed by software (coolbits registry hack)?

Without identifying myself I said I had underclocked my BFG 6800 GT after having heating issues. Not only does the supposed 'supervisor' ("I'm the highest person you can talk to in this company." ) say that it's possible it was damaged by underclocking it to the nVidia reference design clock frequency (350/1000) from the BFG overclocked default of 370/1000 but he also says that if it's sent in they'll detect that the core speed has been changed and simply send it back.

All of my technical experience says he's Full of S... on both counts, but I figured I'd ask around and see what everyone else says. I'll close with another great quote from this 'supervisor.' "Basically you have a $400 dollar paper weight." BFG's professionalism knows no bounds.<P ID="edit"><FONT SIZE=-1><EM>Edited by ahowell2k on 12/24/04 02:04 AM.</EM></FONT></P>

Underclocking cannot damage the card. Infact, it will lengthen the lifespan of it as the GPU is under less stress.

Also, as long as you don't alter the BIOS in anyway on the card (coolbits does not do this) I don't think they can detect a thing.
