SUMMARY

PCs with heavy input/output (I/O) loads e.g. servers that run large installations of Microsoft Exchange or Microsoft SQL Server may report any of the following error messages when using 4GT tuning:

Message 1
Stop 0x0000003F NO_MORE_SYSTEM_PTES
Message 2
Stop 0x000000D8 DRIVER_USED_EXCESSIVE_PTES
Message 3
1450 Insufficient system resources exist to complete the requested service

RESOLUTION

To solve this problem, get the most recent service pack for Windows 2000.

WORK AROUND

To work around this problem, perform the following:

1. Ensure that your drivers are not using any switches or parameters to reduce the use of system PTEs. Examples of drivers that may utilize such switches are the hard disk driver, the network adapter driver, and also AGP video cards that map physical memory.
2. Eliminate registry entries for Page table entries or Paged pool maximum entries. These are helpful for tuning the standard installation. Eliminate these entries when utilizing /3GB switch.
3. Do not use the /PAE switch. Modifying this value does not alter the number of PTEs that are made. Using the /PAE switch initiates the memory manager to utilize two PTEs to map each page of memory.
