Because some programs will not run without a swap file. There is no need to
tinker with it--there is no performance hit unless actual paging occurs and for most users with 512 mb, the swap file will not be used even though it exists. The performance tweaks that have existed for years are really somewhat useless as they were developed when computers were under powered (ram and CPU). There are some tweaks required when 768 mb or more of ram is being used. Here's some info on ram you might find helpful: 768 mb or more of ram: "Out of Memory" Errors with Large Amounts of RAM Installed 253912 http://support.microsoft.com/?kbid=253912 This article contains instructions which basically say: add this line in system.ini, under [vcache]: MaxFileCache=512000 *************************** 1 gb or more of ram: Error Message: Insufficient Memory to Initialize Windows 184447 http://support.microsoft.com/?kbid=184447 *************************** 1.5 gb or more of ram: Computer May Reboot Continuously with More Than 1.5 GB of RAM 304943 http://support.microsoft.com/?kbid=304943 -- Regards Ron Badour, MS MVP for W98 Tips: http://home.satx.rr.com/badour Knowledge Base Info: http://support.microsoft.com/default.aspx?pr=kbinfo "98 Guy" wrote in message ... 98 Guy wrote: I say this because when 98 came out, the typical pc had 16mb of ram and 32 or 64 mb of ram was seen as the outer limits.

For example, if I have 512 mb of ram, why do I want *ANY* swap file? Don't I instead want to increase my vcache size? |

Windows uses a virtual memory system that adjusts to the amount of memory
present and the use of the system. When more memory is available it will use it in preference to the swapfile/pagefile. It will cache more data from the hard drive (VCACHE) to speed hard drive performance. But if you load a large program or a large data set, Windows will re-allocate memory from VCACHE to the system pool, and if necessary, use swapfile/pagefile to expand physical memory. All this is done automatically, and works best if left alone. -- Richard G. Harper [MVP Shell/User] * PLEASE post all messages and replies in the newsgroups * for the benefit of all.

Hi 98 Guy, Ron Martell MS-MVP has an article that will answer most of you questions concerning memory management. http://onlinehelp.bc.ca/tips.htm#virtual Quoting from that article: "While the "total system load" is a realistic measure of total system memory requirements it is often not practicable or even advisable to have that much physical RAM installed in the computer" I don't know when that article was written, but clearly it IS practical these days to have a Win-98 machine with 256 or 512 mb of ram, so he is wrong about that. As for the "advisable" part, he gives no reason why having "that much" ram is not advised. The premise of the article is based on the idea that there can never be as much physical memory as the OS needs given the sum of the "total system load". This premise is clearly no longer valid. While the article claims that Windows 98 with 1 and 1.5 gb of ram is possible (with the appropriate settings), it does not explain the need to still have a swap file or virtual memory in that case. So - can you tell Win-98 not to use a swap file and not to create virtual memory? |

What he said.

You do not need to adjust any settings with that configuration. For the swap file, it is always best to let Windows manage it. You might move it to another disk, but there is no need to set a maximum or minimum. The cache setting only applies above 512Mb RAM. The other settings are not required for Windows, but some DOS programs might require a custom DOS environment that includes them. -- Jeff Richards MS MVP (Windows - Shell/User) "98 Guy" wrote in message ...
