I have a Fujitsu-Siemens notebook with the AMD Turion MT-28 processor. I want the CPU to run at the full clock speed of 1.6Ghz permanently - no CPU throttling.

What would be the point of that? You don't need 1.6GHz to do word processing or play solitaire. The throttling is done for a reason...to keep the CPU temp down & to conserve battery power. It will throttle up when you need it ASUS A7N8X-X Athlon XP 1800+ 8.5 x 200MHz 1024MB PC3200 2.5-3-3-7 Asus A9550GE/TD 128MB WinME/WinXP Pro SP2

You do know that switching from mains to battery raises the overhead load on your laptop and even with throttling not being identical to speedstep it still helps reduce the overhead when you do switch or when in idle state. You may not like the feature but it is there to help the situation, have you checked your laptops BIOS, you may be able to disable throttling altogether from there on your Fujitsu. If the option is there and you have a second second battery or if you are hooked to the mains all the time then disable it, but buying a laptop that's going to be hooked up to the mains all the time is well IMHO unjustifiable. List of lists

Jam is dead on. The processor is made to use as much speed as it needs to. There is no point running it at full speed when it doesn't need to, that would defeat the purpose of a mible process for one and defeat the purpose of it's battery saving technology.

Thanks for the replies, maybe I should of made myself clearer. I only want the full power when I am connected to the mains, obviously if I am mobile I want the CPU throttled back to conserve battery. I have checked the BIOS settings thoroughly and there is no options in there :-( The main reason I want to do this is for playing games. If the CPU is running full speed all the time the game should be faster, yes? Or is the time taken for switching the CPU speed not noticeable enough to make a difference?

Well here is the thing. Unless you got a gaming laptop, it doesn't matter because your grpahics card on that laptop is your main bottle neck. You can have a 2.6ghz in that laptop running at full speed but if you don't have a decent graphics card in there, then it isn't going to make any diff, because if you are looking to play demanding graphic games you can pretty much forget about it if you don't have a nice graphics card in that laptop. I'm going to have to say you prob have a basic graphics card in that laptop, based on the processor you have in there alone.

What I meant based on the processor you have in there alone meaning it's the entry level Turion 64 processor and the 1.6ghz alone isn't going to do you much good with games like Doom 3 and we aren't even talking about the graphics card.
