What gives the best performance boost? Overclocking the Core, Memory or Shader?

the shader and core are usually linked. What a lot of people forget is that core clocks are not the most important, just like in a CPU-FSB-RAM loop the RAM is the most important as it has the greatest effect on the speed at which data is stored and transfered. For GPUs I OC all three of them but try hardest to get the RAM up the highest possible w/o artifacts, then up the shader and clock as gravey.

On different cards, different things are the "weakest link." Usually overclocking the memory will give you the biggest gains, though.

Note that in general, overclocking the memory will have no effect on how far you can overclock the core, so do both!

In my personal experience the shader clock makes the most difference. However this probably varies heavily depending on the type/make of card.

Also depends on how high each componant of the card clocks up.. Sometimes you get more out of one than the other.

For me the memory has never made that much difference in performance in any card I have ever owned.

I usually unlink the shader and core to achieve the highest on both possible.

I would say memory. On my 2400, these are the limits to which i can overclocked:

From - Core - 525, Memory - 400

to overclocked version:

Core - 587, memory - 477

I was told in this (my first GPU overclocking thread ) that core clock was more important. I've been under that impression for quite a while now. What that person wrong?
