Slow performance on the Precision M4800 with Intel SpeedStep enabled



Slow performance issues may occur with Intel SpeedStep enabled on the Precision M4800 Mobile Workstation. This article provides more information on the issue as well as configuration steps to take to help resolve it.


Precision M4800 Intel SpeedStep performance issues

You may experience slow performance issues on the Precision M4800 Mobile Workstation with Intel SpeedStep enabled. The system may take longer than usual to complete a shutdown and experience general slow performance during usage. The Windows Experience Index in Windows 7/8 may also report low performance for the Processor category. You may notice a boost in performance by disabling, or unchecking, the Intel SpeedStep within the Performance settings of the BIOS (Figure 1):

Edit MSCONFIG to ensure Intel SpeedStep is functioning correctly

While disabling Intel SpeedStep may provide a boost in performance on the Precision M4800, the power saving benefits of the technology will be disabled, as well. Intel SpeedStep allows for reduced power consumption and lessens heat production in systems using the technology. Instead of disabling Intel SpeedStep, you may wish to take advantage of the improved power saving features it offers.

To ensure the Intel SpeedStep technology performs optimally on the system and doesn't impact system performance, it may be necessary to edit the Microsoft System Configuration Utility, or MSCONFIG, by following these steps:

  1. Choose Start/Run and type "cmd" in the search box to bring up the Windows command prompt.
  2. Type "msconfig" at the command prompt and hit Enter to bring up the system configuration utility.
  3. Click on the Boot tab and then Advanced options. Make sure the Number of processors is enabled and that the maximum number of processors (4) is chosen from the drop-down list (Figure 2):
