Today we are going to put our nVidia 9600M GT to its maximum performance, which hold up to 140% of its initial capacity!

Graphics cards essentially have 3 “clocks” at different frequencies, the GPU (core chip that makes all the calculations), the DDR memory (where textures are stored and read) and the SHADER (which processes each pixel individually parallel to the GPU)

There are two ways to overclock these graphics cards, hardware (BIOS flashing) and software (nvidia software)

Now we are going to the heart of the matter, if we overclock the card is best to keep the GPU:DDR ratio and DDR:SHADER ratio, I’ve seen many overclocks that work very well without caring this proportion, but if we do this we will avoid bugs (black screens) and the scores in 3Dmark will rise proportionally to the overclock, this will not happen if we went up with the GPU and not with the DDR, etc …

Therefore, for the 9600M GT we have this values (see at http://www.notebookcheck.net/NVIDIA -GeForce-9600M-GT.9449.0.html )

Core Speed 500 MHz
Shader Speed 1250 MHz
Memory Speed 800 MHz

Well, I have tested some configurations an I carry the core to 660 MHz mantaining the proportion (AND ALWAYS GETTING WITH THE DIVISION NATURAL NUMBRES WITHOUT DECIMALS).
I had 5600 marks before and now i have 7636 !!!!

500 / 1250 = 0.4 SHADER
500 / 800 = 0.625 DDR

For 660:

660 / 0.4 = 1650 MHz
660 / 0.625 = 1056 MHz

So let’s open the tool and put the values [660 / 1056 / 1650], sit over a couch in order not to fall, and watch the 3Dmark score!

Hello to all, today and specially to the Acer 5930g forums. I’m going to change a P8400 processor, and we will put a T9600 instead.

1. Remove the laptop battery
2. Remove the screws on the back cover
3. Remove the cover with a plectrum, or anything similar (made of plastic)



4. When opening the cover, we must locate the 9 screws of the heat sink (2 in the chipset, 3 in the processor and 4 in the graphic adapter)
5. BE CAREFUL with the graphic adapter screws, because they are very soft, and you will ned a good screwdriver.



6. Now remove the two tiny screws from the fan (warning, they can fall into the PC, and if this happen, you must dissasembly more parts
7. We must take care with the heat sink, we must have some skill because it’s a little fit, but once removed the fan it’s easy



8. Release P8400 processor with a flat screwdriver, giving 3/4 turn to the plastic screw,you must hear a “click” and it will be released.



9. And here are the two monsters :) , one sais “goodbye” and the other one sais “hello”.



10. Clear the graphic adapter contact surfaces with alcohol



11. The 9600M GT core cleaned!



12. Now use the thermal grease, it will be better to spred a little into the heat sink and a little (very little) in the chips (very spread)



13. DON’T REMOVE THE DEFAULT GREASE FROM THE GRAPHIC ADAPTER MEMORIES because they need to be into contact with the heat sink. I only added a little more of thermal grease.

    

14. It’s also recommended to clean the heat sink with alcohol



And that’s the end!! All is ready and mounted, now we must power up the computer and enjoy with our T9600, soon I will write about the benchmarks into the 3D mark, and how to OC the graphic card to the limits. Now I have 7614 marks!! A NEW RECORD!!

Here are some videos of the projects I’ve been doing with the N95’s accelerometer, they were finalists in the Nokia MobileRules’08 competition, I didn’t became rich, but at least I visit Helsinky and met many interesting people :D

The video with the new projects: NiiMe Play, NiiMe Drums…

(Any day I will re-upload it, because I had a problem with Youtube and the copyright of the original sound…, and now it’s bad re-encoded)

And the last video, handling the pendulum which I have showed two posts ago:

I will develop more applications when I have more time

This is video that show how an automatic Charpy pendulum works, I have developed the software to transform an old manual pendulum to an automated one, the software uses an enconder and some sensors to detect the position of the pendulum, allowing it to autocalibrate itself in 6 oscillations (as the standard ISO indicates).
It has full control over the test, the engine for driving it up and down, the hook for the launch, the brake to stop the pendulum, and the door control as a security measure.
This test indicates a material’s resistance to an stroke (resilience), and shows the result in Joules.

Well, finally instead to post all the topics in separated forums I have decided to focus them in a Blog, everything that you want to see it in the same place :)

Here you can find everything. On issues of software applications and hardware: from the projects that are already in progress, until the projects which are under developing. In areas of photography: my first steps in some competitions and various photographs (especially weather photographs), also from time to time you will see some special weather “follow-up” with its special meteorological story.
Here we go!
