Hello, question about video card.

I downloaded GPU-Z a while back, and noticed that my 8400M GS has a GPU clock of 400 MHz and a memory clock of 500 MHz.

What is the memory speed and how is it different from GPU clock?

It says that the memory is 500 MHz, yet the Nvidia site says that it should be 600 MHz. That means that Dell underclocked it, right?

If I overclock it back to 600 MHz, how much heat increase will there be? At what point would the heat become a major problem when overclocking? A simple increase back to stock value shouldn't be dangerous at all, right?

Thank you

If it means anything, right now the GPU reaches the high 70s under full load gaming.

 

Does it have a fan ?

 

Oh.... It's a mobile...
I'd just bump it up about 10mhz at a time and check the heat..

 

The memory speed refers to how quickly the memory can react. The same applies to standard RAM, for example, my desktop has DDR2 533Mhz and my laptop has DDR2 667Mhz so theoretically my laptop RAM will react quicker.

Then is the stock value of 600 MHz really stretching it?

Edit: Which would be more effective, increasing GPU clock or memory? Which one causes greater heat increase?

 

Make sure it's not the desktop version that has 600Mhz....

 

there is no 8400 for desktops (-_-") maybe 8500... but no 8400

 

Actually, from what I've read there's a desktop 8400 GS.

 

I got it from their official site:
http://www.nvidia.com/object/geforce_8400M.html

Basically, this is a comparison between my card and stock value, first value is mine and second is what they say it should be:

Stream Processors: 16 --> 16
Core Clock (MHz) 400 --> 400
Shader Clock (MHz) 800 --> 800
Memory Clock (MHz) 500 --> 600
Memory Bandwidth (GB/s) 8.0 --> 9.6
Texture Fill Rate (billion/s) 1.6 --> 3.2

 

Sorry, but I still don't know whether to increase the Core/Shader clock or memory clock. Which one is more effective, and which generates a greater heat increase?

 

Did you buy the laptop new ? If you did i'd leave it alone !!!
If you did'nt go ahead and put it at 600Mhz....

 

The nVIDIA site doesn't tell the whole story. Stock for the Dell is what you have. End of story. Now it might be able to run at 600MHz, but that's not sure. It will depend on the type of memory (DDR2 vs GDDR3) and if the memory has been undervolted. It might be that it runs at that speed because it was too hot at 600MHz.
