Just a hypothetical question, and depending on the outcome here, might try to implement it. Is it possible to OC a laptop GPU? Like say OC a GT540m to GT555m speeds, or maybe a little higher?
Im currently running driver version 259.97

GT540m specs at stock
cuda cores: 96
graphics clock: 672 MHz
processor clock : 1344MHz
memory clock: 800 MHz
128 bit interface
1GB GDDR3 memory on card, 2651 MB total graphics memory.

edit: if oc'd would say 750, 1500, 1000 on the respective clocks make a big difference?
 
I oc'ed my 460M GTX just to benchmark ..

Yes it is possible, but the laptop gets super warm and I'm sure pushing too much or even too long even at moderate settings could toast the GPU.

It's not like a desktop where you can use crazy heatsinks and mulptiple fans, its obviously a closed in area with minimal cooling capability.

be careful as its not worth frying your laptop.
Below is a screen of my best run thru on 3D Mark06--so you can see the changes I made from stock on the 460M.

NOTE: To benchmark I used a CoolerMaster SF-19 Cooling pad on max setting--(Dual 140mm Fans), and had all access panels removed to allow flow! The ASUS G73 also has large dual fans/heatpipes built-in and vented out the rear~

I have not such performance. Im only getting 25-30 FPS from BFBC2 at medium with physics off.
That may have something to do with the processor, but I doubt it.
 
that was ran on the i3 IPU. i think i got it going on the geforce now, but only the results will tell for sure i guess.

Oh sorry,didn't notice that,might be my lack of sleep kicking in. :O
Post back the furmark results of your dedicated GPU.I think you can turn off the IPU from the bios.
Also take the reading while the test is running not when you have shut off the application. :d
 
There is no setting in the BIOS to turn it off. I already thought of that before I loaded BF on it. (figured it might be interfering with the dedicated). (it also doesnt have a HT option in the BIOS (as far as I have read the i3-380 is hyper-threaded).

Yes it has HT.
Try updating the bios.It would depend on the bios I guess.
Urghhhh Laptops piss me off.
When you ran the test the dedicated GPU usage was 100% right and then you got 57C if yes then you are good to overclock.
 
the dedicated it hovering at 5% usage. The IPU is hitting 99-100% though. I tried uninstalling the Intel HD driver, and that did not do a thing.
Next up, BIOS update.
