On an Intel Ultra Mobile Platform-based computer that is running Windows Vista, the Windows System Assessment tool (Winsat.exe) displays incorrect processor information. Therefore, the Windows Experience Index score is lower than the actual score.
Note The code name for Intel Ultra Mobile Platform is "McCaslin."
For example, you open a command prompt by using an administrator account. Then, you run the WinSAT.exe –v command at the command prompt. The processor cache size that appears in the command output is not consistent with the processor cache size that is described in the processor's product documentation.
This problem occurs because Intel has changed the cache-size detection mechanism for the new Intel product. Currently, the Windows System Assessment tool does not support the new detection mechanism.
