Can't Detect Shader Clocks

I've been messing around with my Mobility 3850, but I can't seem to find the shader clocks for it. It's greyed out in GPU-Z and it's greyed out in GPU Tools. I have the newest drivers from ATI too.

Anyone know what's up with this?

 

I think its something to do with ati's unified pipelines (Or what not) so we only have core and memory to tinker with.

 

Ahh I see, bummer :/

 

As mentioned earlier, it is something to do with ATI's unified pipelines. From what I understand, ATI's GPU's have their Core and Shaders essentially linked into one, so their clock speeds are the same. I guess you can also attribute this to how ATI's cards always have 5 times the amount of shaders on their cards to NVIDIA's cards of the same power. Don't quote me on this though.

The fact that you can't change Shaders in any overclocking tool for ATI GPU's shouldn't really affect anyone, if you change the clock speed for the core, you are essentially changing the clock for the shaders as well. You will still get the same benefit and performance from overclocking an ATI card compared to any NVIDIA card.

 

with nvidia cards, the idea is that you scale the shader clocks with the core clocks anyway. no big deal.

 

for ATI cards , core and shader clocks is same so they change together...
