Slow System Response with Windows 7* and SM712 On-Board Video Driver

You may notice the system responds slowly after installing an on-board video driver in Microsoft Windows 7*.

  • When moving the mouse or opening a new window, there may be a delay of 2 or 3 seconds
  • New windows may open slowly, or haltingly

Affected products: Intel® Server Board S1200BTS, Intel® Server Board S3420GPV, Intel® Server System R1304BTSSFAN and P4304BTSSFCN

To resolve this, disable the hardware acceleration on the system:

  1. Right-click the desktop and choose Screen resolution
  2. In the Screen resolution window, click Advanced settings
  3. In the Generic PnP Monitor and Silicon motion LynxEM+ properties pop-up window, click Troubleshoot tab
  4. Click Change settings
  5. Set Hardware acceleration to None and click OK

Root cause
The Intel boards and systems affected use an on-board SM712 video chip. The SM712 is a 2D video chip and does not have 3D acceleration capability. This forces Windows 7* to use the CPU to draw window rectangles and video.

This applies to:

Intel® Server Board S1200BT
Intel® Server Board S3420GP
Intel® Server System P4304BT
Intel® Server System R1304BT
