Is it ok to downclock and overclock at the same time?

Now im asking this because i have two profiles stored on my rivatuner, some of my games gets BSOD when its overclock (so ill put it to default) and some games needs a little bit overclock for better performance especially on crysis, now im asking if is it ok to downclock your card and overclock it vice versa while choosing the games to play, if you know what i mean,. I'm kinda worry if this will damage a card...If not then good to go..

I would think that if you constantly shift the voltages and frequency on your hardware, it will wear it out alot faster than running it steadily overclocked. If you get BSOD in games, that means your overclock isn't stable - you will need to do some adjustments until you get it working.

Overclocking/downclocking all the time will kill your hardware.

im not getting bsod when i have this overclock mode with some intense games like crysis , modern warfare, far cry 2 etc.. and i can play 4 hours straight, but games like dead space and some games that hates overclock gpu will just freeze up,so go back to default mode, im doing this for like 5 months now and still im playing with overclocking and default mode at the same time,..

OCCT didnt help either, its like some games dont accept more shaders, when u increase the gpu clock,

i shift between differnt clock speeds all the time and have been doing so for years. i don't overclock but have a substantial underclock by default and set it to default clocks before i start up a game. the difference in frequencies is a lot bigger as what you do i assume and i have never experienced any problems doing this. so as far as i know the shifting is not a problem. in fact, most powersaving features do the exact same thing (like coolnquiet or speedstep on cpu's)

what is a problem is that you are apperently pushing it too far and i would suggest you find a stable overclock.
