What is the Shader, Memory and Core clocks?

post #1 of 13
Thread Starter 
Hi all.
Okay, what I want to know is, what do each of the clocks affect?
I think I have an idea about the shader clock, they're the ones that make the difference when there is a lot of shadows and light, am I right?
What do the rest do?

I'd be interested to know this as well. I know that the shader clock affects the PPD you get when folding on the card the most, though.
post #3 of 13
The core clock is the speed of the GPU chip itself. The memory clock is the speed of the RAM on the board, and the shader clocks are the speed at which architecture inside of the GPU itself, which basically do all the geometry calculations for rendering graphics, run. So core and shaders and usually the most important clocks to pay attention to.

This is mostly true --
-- Ill add a little bit. Overclocking the VRAM will increase bandwidth between the chip and the core - Which usually helps on chips with lower-bit buses. Overclocking the core and shader usually raise the fill rate some, which is how fast it renders.

Also, AMD (formerly ATi) has same clocks for Core and Shaders, so there is no Shader clock to OC with
And with nV, the clocks on the core and shaders increase simultaniously

Hey, thanks for replying.
So memory doesn't matter much then?
From a scale of 1 to 10, how much does each matter?

Core/Shaders/Mem
You can't run a GTX460 e.g on 815/1630/200
It isnt right

Only on the newer gen. Cards. I know older stuff you can overclock separately.

11. Everything is important. Never overclock just one thing, the manufacturer clocks each at the speed its at for a reason; so nothing slows anything else down.

EDIT: Think about it. It would be about as useful as overclock your CPU and not your ram or GPU to go along with.

Yeah I've OC'd my 7600 separatley, pretty sure I did.
Either way his card has linked Core/Shader clocks
