Windows 7: How hard is it to change a graphics card?

Uh, the usual reason that a component is rated for a certain voltage and speed is that it's a trade off between performance, heat generation, longevity, and economics.

The manufacturer sets the spec with the intent that if you run it at the recommended settings, you should see it perform error free throughout the length of the warranty period and beyond. That doesn't always happen, of course. A "better performing" component in the same product line may use a lot of the same electronic components, but in the case of a graphics card, for example, it may have better cooling, RAM heat sinks... Stuff that costs a little more. With better cooling, you can push it harder, so they can sell it with higher specs.

That's a generalization, but it's the basic concept in most electronic designs, and in manufacturing companies, including the one I work and design for.

It is absolutely true. You may achieve a state where the system will not crash but it is far from stable. If the component were to be stable at higher clocks/voltages the manufacturer would have built it as such. A stable system always runs at stock clocks.
just because the builders of the components set the speeds to a certain number doesnt mean they cant run at higher speeds STABLE
my 5770's are running
core clock 942 and memory 1350
stock voltages rock solid stable
cpu @3.8 ghz stock voltages passes all cpu stresses i can also get it too 4.0ghz STABLE but needs a hefty voltage boost
so i have a overclocked STABLE SYSTEM
In your experience you are saying it is stable but unless you are the designer of said equipment it is impossible to say for a fact it is stable. This is true for all electronics. As Mellon Head stated, the manufacturer does set it at settings which provide stability. Bringing it out of stock settings removes the stability the manufacturer guarantees. Don't start a debate with opinions. The statement " A stable system always runs at stock clocks." is derived from the statement "Every task has an intended tool and every tool has an intended task." What this means in a computer sense is only use components as they are intended to be used. Now I'm not saying not to overclock as I am an overclocker myself. (I mean come on, who's never turned a screwdriver into a hammer?) But, what I am saying is if you are looking for stability ; keep your system at stock clocks.

what you talking about
all i said is a component can be ran faster than stock clocks and be stable
nothing more nothing less

and @ above poster
no basically you said if ure pc is overclocked its unstable.
maybe you should rephrase it to "theres more chance of instability if you overclock"

I was clearing up some confusion based on some previous posts.

Frex...

The two bolded parts are at odds with each other. You both are correct, and you make the point that your system is stable at overclock. Not every system is actually stable at OC, and Davidxtux's point is well made. I simply gave a supporting reason from a designer's perspective. That's all.
