First of all, my Gpu is an XFX One-R Series HD 5450, 1gb GDDR3, Passive Air cooled.
I know its cheap and its no the best graphics card out there, but currently i cant afford a new one, im planning to get a gtx 750.

During all the auto tune the temps were stable at 76c-77c

So, this card has 650mhz base core clock, the tune turned it up a little bit to 690mhz ocd

The memory clock has 1066mhz effective clock, but runs at 533mhz base, the auto tune raised it to 888mhz ocd. The whole auto tune thing lasted about 20-40 minutes, the temps were stable at 76c-77c. After it finished the clock bars were set, and i activated the Graphics Overdrive, just after that i checked the temps, still stable, and 40 seconds later. BOOM. Gpu crash, weird lines and color artifacts popped up for 5 seconds, and finally. It happened, black screen, pc still on, Overdrive "Auto tune" failed, and time wasted.

The question is: Why it failed, if the temps were stable, during, and after the overclock. I have no idea, and that is why i contact the community, for help on boosting my crappy gpu performance so i can get the most out of it until i get the 750.

And also, why if the effective memory clock is 1066mhz, it runs at 533mhz?
 
Solution
Overdrive doesn't do a thorough test. Your applications may stress your gpu much more than the test. Also, just because temps are stable does not mean that the chips can actually handle the speeds assigned without errors.

I agree with Calculagator, auto overclocking applications tend to be unreliable. We just have not made those advances yet. Overclock manually until you see artifacts or instability, drop it back a bit and I always run a 24 stress test to thoroughly check with Valley Benchmark on loop and Haven to make sure my games and apps will not crash.
