Are these settings too high?

Question

All I did was click on the Performance 3D in the settings of Clock Frequencies of my FX5600 128MB. I then clicked on Auto detect and it changed my settings all by itself. I did not manually move any of the sliders.
My Core Clock Frequency for 2D is now 270MHz and 3D is 372MHz.
So far, America's Army plays way better and I was even able to bump up many of the games settings too.
Are these settings too high?

Answer 1

Both, but primarily the GPU will generate the most heat, either way, heat is a killer no matter how you look at it. Even if it is warm to the touch, that does not mean it's harmless. If it's warmer than the component manufacturer specs indicate, it shortens the life. As to the rate in which heat above a certain range actually shortens the life is better left to an electronics engineer or a spec sheet.
Do not overclock in 2d mode it's not necessary.
Probably not an issue if you have good cooling in your case and the ambient room temp is respectable.
If you want to overclock, let the 3d detect set it initially and then take the overall speed and reduce it by 5% or so. You may not notice failure right away if your eye is not trained to see the problems. So it's best to be conservative if you are not an experienced overclocker.
