Windows 7 Beta & Centrino

[cavaille]

Thank God I´ve found your forum!

I hope, anyone can help me... I´ve installed Windows 7 official Beta on my old Centrino Laptop. So far this works like a charm on my old PC, fast, reliable etc.

But I have one problem: the CPU (Centrino 1,7) always runs at its full frequency of 1.7 Ghz. The fan noise is quite annoying. I already tried Notebook Hardware Control with the matching ACPI set for my Laptop (FSC Amilo 1425) but NHC can´t change the frequency. The energy options doesn´t help either - I can use whatever I want, the frequency stays at 1.7 Ghz and the fan stays noisy. Under XP the processor is reduced to 600 Mhz when not in use (even without NHC), under Windows 7 this doesn´t work. Driver installation worked perfectly, my chipset from Intel (855PM) was properly recognized.

Did I do something wrong? Or are there other drivers? Thanx in advance.

Really I don't know what's the problem.
First thing thats bugs me, is: Can Win Vista change CPU frequency?
Second: Have u tried RMClock? Seems that NHC works for Core Duo (my T2500) but maybe it has problem with older one? You always can check

shouldnt 7 automatically underclock your CPU....

thats what the power plans are for....

unless you are using a high performance profile you shouldnt have a problem underclocking your cpu....

underclocking sadly is not possible - and I tried every mode Windows 7 offers. I´ve read about underclocking with Windows Vista - there the processor should be set to a minimum of 15%. This doesn´t work.

Windows 7 also can´t change the display brightness. Maybe there´s a problem with the ACPI Windows 7 uses. I have a power saving button which underclocks the processor, the GPU and at the same time adjusts the fan-speed. On Windows 7 the fan speed is adjusted - but the processor and the GPU stay at their highest frequency.

Right, thanx. But have You tried a RMClock? Check all options in profiles, then expand it, click Power Saving and check only the first one in "Use P-state transitions" - with the lowest FID. Then enable that power setting in profiles and go to monitoring screen. Raport after that

Thank you! This works perfectly. The PC runs at 600 Mhz and doesn´t even feel that much slower, the fan is not disturbing anymore. You guys are great.

The latest bios is from 2005 - FSC doesn´t care about its customers that much. But thank you.

Nice to hear that RMClock works There are 3 other settings there, Max Power, select only highest FID and Perf. on demand - check all of them. Also, you can set OS settings for every of them to match them to system settings - I use "balanced" for Perf. on dem., "High perf." - for Maximal Perf, and "Power Saver" for power saving.
