0 Compression Utility

Each computer needs compression software to open certain file types as .zip, .rar, .tar, .7z, and many more. Why compression are important? Because it can reduce file size, and can merge many files become one file (compressed file).
That reason make you need a compression tool. Many compression tools that available to choose. Now, let's discuss them.
1. 7-Zip
This utility is free, open-source, 7-zip has best compression performance than other applications. It fast, high compression ratio and only consume a little of memory. But, 7-zip has less interesting view. We recommend 7-zip because it very quick, safe, and free.



2. Win RAR
 Who don't know Win RAR, famous compressing tools. This tool also has good compression performance, about 110%, but worse than 7-zip that has compression ratio 100% (less mean better). Win RAR is shareware, so, you need pay to use Win RAR. This tool has better view than 7-zip.


3. Win Zip
Win Zip also a good utility in file compression, file sharing, and file encryption. Win Zip has good performance, and very light as well as Win Rar, about 114% compression ratio. Win Zip is shareware,  but, you're allowed to get it's trial version.


Ah, there are other compression tools, they also good, and worth to try.
1. Pea Zip   Good alternative.
2. AlZip      if you need speed and minimum resource needed.
3. IZArc     Good freeware WinRAR or Win Zip alternative.

0 GPU Overclock Guide

You have a GPU, but, it works slow?
Now, i will show you how to boost your GPU performance
This way works with improve increase your GPU clocks directly.
These are the steps :
1. Download RivaTuner 2.24c from Guru3D.
2. Install RivaTuner 2.24c and if you are asked for install update, select install update.
3. Run RivaTuner (If show unsupported drivers, ignore it).
4. Wait RivaTuner to scan your hardware, registies for Forceware, Catalyst 
5. If your GPU(s) are nVidia will be shown Forceware detected, and if your GPU(s) are AMD will be shown Catalyst detected.
Note: Don't Overclock your Integrated GPU, only for dedicated GPU
6. Click Triangle next to "Forceware/Catalyst detected"
7. RivaTuner will show new window. Give check "Enable hardware level overclocking"
8. Now, select Performance 3D and slide the slider below "GPU clock", "Memory clock", and "Shader clock"(if supported) until you find desired clocks.
9. If you have found desired clocks, now, click Save under Startup settings and check "Apply Overclocking at Startup".
10. Apply and OK.

I try above steps using GPU nVidia GeForce 9600GT
And I have done benchmark for it (3Dmark 2003) 1024x768 noAA. 
1. Before overclocking (450 Mhz, 500 Mhz, 1000 Mhz) the result is 15990
2. After overclocking ( 600 Mhz, 625 Mhz, and 1250 Mhz) the result is 16450

It also increase Frame Rate while i play Crysis : Warhead at mainstream settings, about 2.5 - 3.25 fps.

Note : Only slide the slider between blue indicator (save overclocking, no other cooler needed)
