Hi,

Server OS - Windwos 2008 Enterprise Edition 32 bit
Database - SQL Server 2008 Standared Edition 32 bit
Memory - 32GB.

As per current configuration setup as below

1. AWE - enabled in SQL Instance side.. But OS level not enable and not adding /3GB or PAE switch in boot.ini file.

2. LPIM - Not Enabled and not added SQL service account in LPIM at local policy.
(In windows 2008 if facing error like memory swapping out in error log file then only need to enable at LPIM when configure AWE option)

Pl. confirm as below steps for proper configure in AWE.
Step1:
Set Max memory - 6144 MB at SQL instance file ( Total 32GB memory assign 6GB in SQL and remain other application & OS side, this server is not dedicated SQL)

Step2:
C:\> bcdedit /SET IncreaseuserVA /3GB 3078

Step3:
SQL Service account added into LPIM at local policy (is it require in SQL2K8 standard edition?)

Step4:
Restart the server for take effect AWE feature.

/PAE needs to be in the boot.ini, not /3GB, or IncreaseuserVA

Thank you for reply..

1. Please confirm, 'step3', is it really required?

As I said

/PAE needs to be in the boot.ini, not /3GB, or IncreaseuserVA


You have 32 GB of memory in that machine. If you add the /3GB, you will limit the total addressable memory (the max amount that Windows can see and use) to 16GB. Since I'm sure you don't want to make half the memory unusable, not /3GB. You need /PAE in boot.ini

Yes, locked pages in memory is required
