Overclocking potential in Znotes?

How much can you overclock the CPUs in Znotes whitout having any heat issues?

I'm planning to get a T7700 2,4 GHz and want to overclock a bit, because I know the desktop C2D are very VERY overclock friendly!

 

The stock settings are: 475mhz for the core, 1024mhz for the shaders and 400mhz for the memory.

I think you can take the core up to 600mhz pretty easy. Shaders about 1300 or even 1400mhz. Memory will run at about 450 easy and i have seen 512mhz. Higher is possible but these numbers have been reported to work pretty well. I think most people just overclocked to run 3dmark so I am not sure if heat becames a problem after a few hours.

Overclock at your own risk! I dont see the need for overclocking for current games since they run good at stock speed.

 

Ok sounds nice.

But what about the CPU ? Can I push the 2,4 GHz -> 2,6-7-8GHZ ?

 

You cant overclock the CPU. The Intel chipset doesnt support it.

 

I can never understand why someone wants to buy the fastest current intel mobile CPU and overclock such a sweet processor.

In laptops you have a big problem: the cooling system is designed to deal with the system, not overclocked. Excess head generated would stress mobile versions in comparison to there big brother, alot more and in doing so, you may get an early failure which I bet any vender would not support.

And before you suggest they could not tell, I beg to differ, there are many tests that would show other wise.

2.4Ghz dual cpu cores not enough ? with advanced instruction set.
most desktops don't go there.

 

The first batch of 6224W and 6324W have a bios problem. There is an update that makes the T7500 and T7700 work but Zepto will not sell them with this config till barebones with the new bios arrive and all pre orders have been delivered. It is too much work to update the barebones before production by hand. Zeptos did this for the customers that had already orderd only. So in 4-5 weeks faster CPUs should be available again depends how long it takes the Chinese to update the bios in the barebones.

 

how to underclock the VGA ?
In Vista ?

The VGA is overclock by default
Just wanted to see if afects the batery time

 

It is not overclocked by default. You are using RVTune to read the core and shader speed right? It shows the wrong clocks. Use a different tool and you will see. ATITool works well (yes ATITool work with nvidia graphics cards). You can downclock the graphics card alot with it too.
