Modify your ATi Radeon Memory!
Version: 12.1
Revision: 33 Build 13
Modify your ATi Radeon Memory!
Introduction: A couple of days ago, I was modifying my “ATi Catalyst Driver” for Windows, just before installation. It took me a while to re-write most of the lines. but it’s worth the performance!
On the other hand, this tweak will only change your memory to their maximum capacity. For example, if I have this chipset: ATi Radeon HD 4870 (1GB) which only stated as 512 MB, then you will need to change that digit to 1024 MB.
Tips: If you don’t know your chipset, HWinfo32 will analyze your GPU and notify you with the correct chipset.

1.] Install “HWiNFO32” and run the application.
2.] Wait for it to load and look at the GPU chipset. It is located at the upper – right –corner in your dialogue box.
3.] Keep your previous application running and search for the installation folder.
By default, it should be in your system hard drive. If not, you may have left it somewhere…
Default directory
———————–
C:\ATI\Support\9-8_legacy_xp32-64_dd_ccc\Driver\XP_INF
4.] Look for this file: “CX_85695.inf” and open it with “Notepad-Plus”. You will immediately see a bunch of codes.
5.] Scroll down to line ‘5100’ and look for this string: ‘MaximumDeviceMemoryConfiguration’.
Example
———————–
[ati2mtag_M10.GeneralConfigData] MaximumDeviceMemoryConfiguration=128 MaximumNumberOfDevices=4 SessionImageSize = 16
———————–
Notes: if you can’t find your ATi Radeon Chipset, you may want to press “Ctrl + F”, paste the codes into your search box and click: “Find Next”.
6.] Modify your GPU memory and save your changes.
Warning: if your cards support 1GB of VRAM, you will need to apply this figure: “1024 MB”. However, you cannot go over it’s overall capacity!
Example (Default).
———————–
[ati2mtag_RS600M.GeneralConfigData] MaximumDeviceMemoryConfiguration=256 MaximumNumberOfDevices=4 SessionImageSize = 16
———————–
Example (Modified).
———————–
[ati2mtag_RS600M.GeneralConfigData] MaximumDeviceMemoryConfiguration=512 MaximumNumberOfDevices=4 SessionImageSize = 16
———————–
Figure MB * = ATi Mobility Cards (Not compatible with all ATi Radeon cards).
Figure MB ^ = This is only for 64-Bit operating systems with 2GB VRAM.
Warning: this modification will only work if your cards support 128 MB or more!
Please avoid changing your 64 MB VRAM (Low Memory GPU). This may cause your computer to black out or crash!

7.] Install your modified driver and have fun!
