Hello,
I bought an MSI GE603 which has a GT 425M GPU. when i use GPU-Z to monitor the clock rates it shows them (when running a game) as less than half of the clock rates the GPU is meant to perform at (e.g. it says the core clock rateof the GPU is 560MHz but the highest it gets to on the monitoring tab is 202.5 MHz).
I have tried pretty much all the overclocking tools out there and none of them seem to be able to overclock the GPU, for example using msi afterburner when i move the slider up tp a higher clock rate and click apply it just jumps back to the original clock rate.

can anyone help me overclock?

and why is my GPU only clocking to half of what it should be?


thought i should post my actual GPU clock specs:
GPU clock: 560MHz
Memory: 800MHz
Shader: 1120MHz

but the max my GPU ACTUALLY gets to in GPU-Z sensor is:
GPU clock: 202.5MHz
Memory: 324MHz
Shader: 405MHz

thanks

These are prbably just the desktop 2d clocks. It will go higher while you game. I would imagine that a laptop GPU might have overclocking disabled for its own safety.

Might be a driver issue, try another.

A video card can have different clock profiles for desktop-idle 2D, desktop-active 2D and gaming-active 3D. A notebook video card will also down clock itself when you're running of the battery and will only go up to the rated speed in 3D games when plugged into a wall socket.

This can also be caused by the adaptive power management feature. It would sometimes downclock when it shouldn't. You can alter the settings inside the nVidia control panel > 3d settings > power management. Try it at max power and see if that solves it.

The clock speeds I get are from GPU-Z running in the background while playing a game so the GPU is definately stressed and still has low clock speeds

iPlayer

Did you try with what I posted earlier?

footballpoker

hey, yeah i tried putting the power management mode to 'prefer high performance' or whatever but its still not clocking high. i also have an intel graphics media accelerator integrated card, i dunno if that has anything to do with why the nvidia card is clocking low? :S

Have you tried running a game with GPU-Z refreshing in the background, then checking what the max clockspeed was on the sensors tab?

Hum.. I was assuming he was looking at the highest readings shown there. Or try one with OSD overlay.

footballpoker

yep blibbax thats what i did.
i also found that if i disable the gt 425m in device manager games still run at the same performance as when it isnt disabled. is this because it isnt actually disabling? because i doubt it could play games like fallout 3 without an actual graphics card installed...

iPlayer

I think that's because it's running with the i5's integrated gpu.

Try pressing the 'GPU boost' button on your keyboard to switch to the discrete nvidia gpu, and see if that fixes it. The one that looks like a battery will switch it back to the integrated.
