I got mine from Task Manager &gt; Performance and it is 6843MB with the same configuration as yours. In 32bit you have to take 3325MB as RAM basis, not 4GB's. </p> http://www.howtogeek.com/forum/topic/32bit-os-with-4gb-ram-swap-still-needed-#post-25176 Mon, 19 May 2008 11:08:26 +0000 Deney 25176@http://www.howtogeek.com/forum/ <p>So this would not be advisable on Vista? Mine currently allocated is 3881MB, I have 4GB of RAM on 32bit, does this seem right? </p> http://www.howtogeek.com/forum/topic/32bit-os-with-4gb-ram-swap-still-needed-#post-25117 Mon, 19 May 2008 01:55:36 +0000 whs 25117@http://www.howtogeek.com/forum/ <p>Some more thoughts:</p> <p>1. 32bit adresses 4GB's. But Vista really only uses 3.2GB's because some of the other space is used by components like graphics, etc.<br /> 2. The page file (swap file as you call it) is typically 2 times the size of the RAM. The more RAM, the bigger it is.<br /> 3. Superfetch manages the virtual memory which is RAM plus Pagefile (e.g. 12GB's for a 4GB RAM system). Your system would look very sad if you deleted the pagefile in Vista. In XP that may be another story because XP had no Superfetch - it had a Prefetch.<br /> 4. I understand you can gain performance if you put your pagefile on an internal disk (not partition) that is different from the OS disk. But I have not tried that yet. That's on my to do list.</p> <p>PS.

An ILC reference is pretty obscure.

Any 32 bit OS has the limit of addressing memory of 2^32 bytes, ie. 4 GB</p> <p>So on a system that's equipped with more than 4 GB of RAM, there's no way for any 32 bit OS to address anything beyond 4 GB boundary; so is there any reason to allocate swap for 32 bit OS that runs on a 4 GB system ?? </p>
