What you need to undervolt
In order to achieve a good undervolting, we need some programs.
1. RM-Clock Utility – In this application we perform the undervolting. A must if we want to make it work.
2. Prime 95 – This application enables us to stress-test the CPU to see if it’s stable and what its max temperature is. Not a must. A similar application will do just as fine, or a demanding game. Using both of them is recommended.
3. Mobilemeter – An application that will measure the temperatures of the laptop. Of course you can use any type of application that works with your computer but I use this one.
4. 3DMark 03/05 – If you are unsure and really want to check that there are no performance losses, you can use this application.
Then we need a test-computer! In the following tests we will use this computer.
Acer Aspire 5021WLMi
|Processor||AMD Turion 64 Mobile ML-28 2800+ 512 L2-cache (1600 Mhz)|
|Memory||512 MB 333 Mhz 2×256 MB|
|Monitor||15.4″ WXGA 1280×800 px Crystalbrite|
|Video card||Ati Radeon x700 128 MB|
|Modem, WLAN, LAN||Yes, 54BG, Gigabit LAN|
|Operating system||Microsoft Windows XP Home Edition|
Now, on to the undervolting.
