Why an i7-3630qm is working at 899Mhz instead of 2.4Ghz or an i5-3337u at 770Mhz instead of 1.8Ghz ?

Hello and help.

On my Dell Inspiron the i7-3630qm is working at 899Mhz instead of 2.4Ghz. Fan is at maximum speed. With CPU stress the temperature is 53°C.

On an other laptop the i5-3337u at 770Mhz instead of 1.8Ghz. Fan is at maximum speed (5100tr/min). With CPU stress the temperature is 46°C max.

Laptop has never OC.

I can't find help about this problem anywhere.

Thank's

Update your dell bios. If that does not fix the issue, contact dell for support of their laptop.

thank you for the suggestion. BIOS is the latest version on 2 laptops. One is a Dell but not the other.

Is it possible that this is related to an overheating problem?

Is there a degraded mode on Intel processors?

Hello J-shog,

Thank you for posting on the Intel® communities.

I was checking this thread and I would like to know if you still need further assistance. I agree with Al.Hill information that this behavior seems to be related to a BIOS setting issue.

Based on the information you provided regarding the temperatures (46°C-53°C) reported when running stress test, this does not seem to be an overheating issue, since both processors have a Tjunction value of 105C (Junction Temperature is the maximum temperature allowed at the processor die.).

This behavior could be related to Enhanced Intel SpeedStep® Technology for Intel® Processors being enabled or related to Power settings.

1- Check Processor Power Settings on Windows:

Right-click the Start menu and select Control Panel >> Click Hardware and Sound >> Select Power Options >> Find Processor power management and test adjusting the settings.

2- Check (if available) any other Power Settings in the BIOS. For details on Power Settings options, please contact your system/computer manufacturer (for instance, DELL™).

3- Since both processors support Enhanced Intel SpeedStep® Technology, we recommend you to contact your system/computer manufacturer for any settings in the BIOS that may relate to Enhanced Intel SpeedStep® Technology. This feature allows the system to dynamically adjust processor voltage and core frequency, decreasing average power consumption and heat production.
