1GB RAM & VCACHE 1GB RAM : Limiting VCache IS ESSENTIAL (Win98, SE, Me, 95)
Enter the lines in this color in the [VCACHE] section of SYSTEM.INI
Mainly games usage:
minfilecache=131072
maxfilecache=131072
You can try lower but a gain is unlikely (increase/decrease in steps of 2048).
Mixed usage:
minfilecache=131072 (or do not set it)
maxfilecache=491520
Mainly Windows/Applications usage:
maxfilecache=522240 (MaxFileCache should not exceed 524,288). No MinFileCache
All Users:
When you are satisfied with the VCache size, you can add the following lines under the above:
chunksize=2048
namecache=4096
directorycache=96
Note: If you ARE setting a MaxFileCache and have more than 128MB RAM, then you should first try limiting MaxFileCache to about 70% of total RAM. MaxFileCache should not exceed 512MB.
• Read ConservativeSwapfileUsage=1 (limit paging if RAM >96MB & there's little/no paging).

LARGE RAM PCs"Out of Memory" Error Messages with Large Amounts of RAM Installed
1. The computer may stop responding (hang) while Windows is starting, or halt and display the following error message:
"Insufficient memory to initialize windows ..."
2. You may be unable to open an MS-DOS session (or command prompt) while Windows is running. Attempts to do so may generate the error message:
"There is not enough memory available to run this program ..."
Cause:
Vcache is limited internally to a maximum VCache size of 800 MB.
On computers with large amounts of RAM, the maximum cache size can be large enough that Vcache consumes all of the addresses in the system arena, leaving no virtual memory addresses available for other functions such as opening an MS-DOS prompt.
This problem may occur more readily with Advanced Graphics Port (AGP) video adapters because the AGP aperture is also mapped to addresses in the system area of RAM.
Also read Error Message: Insufficient Memory to Initialize Windows at Microsoft.
Remedy:
To work around this problem, use one of the following methods:
1. MaxFileCache: Set it to 512 MB (524,288 KB), or less, in the [Vcache] section of System.ini to reduce the maximum amount of memory used by VCache (use maxfilecache=524288) .
2. System Configuration Utility: Use the SCU to limit Windows to using 768MB, or 512MB, or less
- or - enter
MaxPhysPage=30000
in the [386Enh] section of System.ini.
3. Physical memory: Limit the amount installed to 512 MB or less (Yes! Take some out!) |
