New to overclocking, Radeon HD 5670 limits?!?

[N1kosBond]

Hey guys,

I wanted to learn how to overclock, so I read a few topics and articles-guides and tried to overclock an old ATI Radeon HD 5670 1gb GDDR5 from gigabyte with msi afterburner and ati ccc

However, in every single article I have found there was a limit to how much a card could be overclocked before is starts crushing, long before the limit to the gpu's max core clock and max memory clock was reached.
However, both programms only allow me to set core at 850mhz and memory at 1050mhz, and not even a single mhz more, while I cant edit the core voltage or the power limit
(The factory settings are 750 and 1000, and I did unlock the voltage control at afterburner)

thats almost a 14% increase on core, and 5% on memory, the clocks you have achieved are good!

BUUUUUT it is as stable as before and I feel no difference, it doesnt give me that feeling of excitement I was expecting from the overclocking thing 😛

Honestly, not to be a high end whore, but i dont think you would on that card as its low end, you will be getting such unnoticeable increases, but every little helps!!
