Bullshit; I've fried Nvidia cards from overclocking before, and gotten a replacement card for free.2 things first bios records and second sometimes if you oc a part of the chip or pcb changes color if you oc a radeon sometimes on the pcb a spot will turn from one color to another usually yellow to black or if its nvidia green to some other color.
Bullshit; I've fried Nvidia cards from overclocking before, and gotten a replacement card for free. Dude what cards and what companies?(evga,bfg,etc)2 things first bios records and second sometimes if you oc a part of the chip or pcb changes color if you oc a radeon sometimes on the pcb a spot will turn from one color to another usually yellow to black or if its nvidia green to some other color.
You are teh stupid.In theory it is possible through JTAG Boundary Scan of the GPU and RAMDAC. Not all chips are enabled to record clock speeds changes and not all the cards assemblers enable this features, but in theory it is really possible.
In all the recent chips there are some locations (256-512 words usually) of e2prom that record hardware configuration changes and faults. This is standard behaviour of many chip manufacturers.
But this is in theory!
JTAG scanning of theese records can be done but the manufacturer itself and the card assembler only (the JTAG registers involved aren't publicly documented) and it is used for debugging e production monitoring only.
So, since it is really possible to discover a card fault due to OC, in practice none of the card or chip manufacturer will ever check for this: it will be more expensive than simply replace the part free of charge.
And least but not last, every card manufacturer shines when he knows that his card can be OCed to higher clock speeds than the competitor ones!
I've heard this as well, but didnt want to speculateIt's actually not that expensive. Each company has a hound in their RMA department that can sniff out the burnt smell of an OC'ed card. :roll:

So how do they know if your graphics card has died because of overclocking ?? Is there something in the bios that indicates OC?? What about using software to OC instead ?? I am asking this because I want to OC but am afraid of breaching warranty.
I overclock for a maximum score, and I'm not kidding. I have burned up cards less than 2 days old in my system....and that's the way it should be.Overclock smart and do it at your own risk please. Not someone else's.
