Overclocking VGA Notebook: NVIDIA GT540M

Increase the speed of VGA (GPU) notebook is not a common thing to do. However, that does not mean impossible. Already several times we featured an article about overclocking the notebook VGA.This time, the VGA will we "pull" is NVIDIA GT 540M. Notebooks that we use is the Acer Aspire TimelineX 3830TG with a Core i5-2410M.

Preparation

We deliberately did not do the extra cooling is extreme. We only use a laptop cooler is standard. This is done so that the results obtained can still be copied by ordinary users.

Use this utility to avoid the occurrence of throttling or decrease in speed due to heat.

Since the notebook is used to use a single system for CPU and VGA coolers, we are forced to use a software utility that ThrottleStop to hold the processor does not do throttling. Setting that we use is to lock the multiplier at 22x (CPU working at 2.2 GHz), with no turbo. This rate should have been safe enough if you are in a cool room.

Here it is our main overlclocking software.

Software overclocking is used only NVIDIA inspector. This software can be easily found in some of the leading websites. You simply do the googling and found this software for free.

Powerplan Ensure Windows is set to High Performance.

To maintain the performance of the notebook still excellent, make sure that the notebook works by using the power adapter. After that, use powerplan "High Performance". Well, now we are ready to overclock.

Overclock settings

After several attempts, finally obtained by setting the GPU clock 810 MHz, 1620 MHz shader, and memory 950 MHz. This setting can still be smoothly on our simple test rig. The maximum temperature is already reached the range of 80-degrees Celsius, but the notebook still works smoothly. It seems that high temperatures are not achieved by a constant, so the system still work with stabilized.

Results Obtained

GPU overclock from 672 MHz to 810 MHz and memory from 900 Mhz to 950 MHz appear to provide increased performance in 3DMark 11 is the first time we test.

From the score of "3-digit" to "4-digit" .. not too bad, right? Increased 14.2% obtained in this test.

After seeing an increase in 3DMark 11, we moved on to RE5 game with DirectX 10 settings, resolution 1360 × 768, and all other settings at the maximum position (including FSAA max). The result, we managed to avoid the minimum fps game of the range of the 20s, to be always on top of 30 fps.

This game can now be played with very smoothly thanks to improved performance of 13-14%.

Less satisfied with these results, we tried to DirectX 11 games, Lost Planet 2. Settings are usually still can be used is Shadow detail, Texture detail, and Rendering levels in MID position, DirectX Features on LOW setting, with a resolution of 1280 × 720 and without FSAA. Generally, we can only obtain an average score of 29-30 fps fitting. Overclocking results led us to a score of 34-35 fps, which makes this game was more worthy to be played.

Setting DirectX 11 managed dipermulus with the help of a little extra energy.

Conclusion

Overclocking blend GT 540M and Core i5 2140 did seem a bit "overkill". Increased successful we obtained 13% -14% range. Indeed, although significant, but not phenomenal. However, for certain conditions in which the game settings have to be lowered and you still need a little extra effort, overclocking can still help. Just make sure that you use a laptop cooler and better in an air-conditioned room while doing this practice.
