I have a Xeon server with 8G memory. For some reason I have to stick with windows xp 32bit. That’s really a pain for me because of the 2G limit for application space while I need a lot more memory to cache the data from 8 1394b cameras working at 1024×768@30fps. These 2G memory could only hold on less than 1 second before it is filled up. I tried to use JPEG compression to reduce the data flow to the hard drive, and also used RAID0 to increase the performance. However, this problem is finally solved by ramdisk. I’m so excited about this. This issue has confused me about 2 yrs.

Step 2
You need to download Gavotte’s RAMdisk. There’s many options, but usually they are paid options, or they aren’t able to make use of the unadress RAM. It’s not the case of Gavotte’s Ramdisk, it’s a freeware that can use that unseen RAM.

Step 3
Unzip the folder and double-click “ram4g.reg” file. You need this Registry before doing anything else.

Step 4
Go to C:\ and open your boot.ini with Notepad. Here you’re going to see something like that:

[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS=”Microsoft Windows XP Professional

” /noexecute=optin /fastdetect

Add /pae ate the end of the line: then reboot
