SatPro A60 can hardly operate at 2.8 GHz since problem of thermal regulation

Hey guys, a nightmare for A60, its CPU clock can hardly run at 2800 MHz, it is supposed, since 75 of the A60? Thermal regulation time is too easy to access.

Using the processor RightMard and Mobilemeter clock utilities, I found the temprature entry A60 to thermal regulation 75? When this temperature is reached, cpu clock slow down up to 1500 MHz (you can't see it using the normal test program, because Throttling is like cheating... that is to say force CPU to stop for some time in order to avoid overheating), and when temperatures rise less than 70?, he will return to 2800 MHz. Another delay: the auto-off temperature is 85? for A60.

Although the temperature which got the Mobilemeter is the sink, not the CPU core temperature, it seems that oshiba made this 75? Date limit too low (default time of Intel is probably about 90?). In addition, with evil designed sink heater, the temperature remained generally above 70-80? with room temperature 15? and only some word processing or navigation base and also with the machine almost free of dust. All this means that the laptop can hardly run at 2.8 GHz. You could never have this speed in any graphical game.

The real clock must be test using RightMark clock, it allows to test if the CPU is forced to stop frequently due to thermal regulation. Everyone wants to do this experience can download these two free software of:

with SuperPI, who can make as high CPU temperature as you want opening it serval times at the same time

Finally, my original idea to write about it here is not only to tell a truth, but also I want that people of Toshiba could do something on this issue, or do an updated bios updated to allow to off the thermal regulation, or make the deadline for her superior to only 75? ,
as you have about bios satellite 1805 last updated:

Version 2.10 24/09/2002
A change has been made to allow only BIOS enable and disable the CPU limitation during the operation of Windows 98SE.

Give the original CPU speed, because that's the only reason I and a few other people chose this machine.

Hi Al

Well, I put t know if you have experience in the technology of the laptop but heat is a known issue on all laptops. It s a fact that all the parts (Cpu, graphics card, etc.) in the unit produce a lot of heat and it s very difficult to cool these rooms because there is no place. You can't compare the computer laptop and desktop PC!

In addition, to protect against overheating of the CPU has an internal temperature sensor. (You know that) If the temperature of computer s reaches a certain level, the cooling fan is turned on or processing speed is lowered. You can choose to control the temperature of the CPU by the setting of the fan first, then if necessary, reduce the speed of the CPU.
Alternatively, by lowering the speed of the CPU first, then if necessary, turn the fan. You can use the element of the standard tab cooling method in Toshiba Power Saver.

Here are the features:
Maximum performance: Turn on fan first, and then if necessary decreases the speed of the CPU processing.
Performance: Use a combination of fan and a decline in the processing speed of the CPU.
Optimized battery: Lowers the speed of the CPU first, then if necessary turns on the fan.

In addition if the temperature of the CPU reaches an unacceptable level with two parameters, the system stops automatically to avoid any damage.

Hopefully this description can explain this problem.

Best regards
