Page file question.
I want to move my page file to a partition on my other hard drive. How big should I make it?
Do you guys have some more info regarding this process?
Thanks!!

i always just use the recommended size.
for my system it's
minimum allowed: 16mb
recommended: 11134mb
hope that helps you

Hi Bull,

Some points on page files . . .
- If you have only ONE physical hard drive -- even if it is partitioned -- leave the page file in with the operating system. Putting the page file in a second partition just makes Windows have to work a little bit harder.
- If you have TWO physical hard drives, the second one is probably a better location for the page file. I say 'probably' because it can depend on how you use the system. The page file is best located where there is the least file activity when its services are needed. Some applications, PhotoShop, for example, have their own cache/scratch file systems that can be pretty intensive. Having the page file on the same drive -- even worse, in a different partition on the same drive -- does no good. Here, knowing the characteristics of your applications and experimenting are the order of the day.
- If you have THREE physical hard drives, odds are good that the best location for the page file is on the odd man out -- the drive that is neither your system drive nor the drive that is your primary work space. Aga, experiment. If you 3rd drive is an ancient slow-poke, it probably isn't a great idea.
- As for the size of your page file, my best advice is to use a DEcreasing, sliding scale with the following parameters: (a) for a system with 2GB (or less) memory installed, set page file to 3x installed memory with a 4GB minimum; (b) for a system with 4GB memory installed, ramp that number down to 2x installed memory; and (c) for a system with 8GB (or more) memory installed, drop the multiplier to 1.5x installed memory. Also, note that a large page file may not be needed at all -- it all depends on the applications you use and how you use them and how many you use simultaneously. The 4GB minimum is probably a good estimate for any system running any version of Window from 32-bit XP to 64-bit Win7; however, if you are single-tasking, or browsing while running various office applications, you probably don't need more that the 4GB page file, regardless of your actual installed memory.
- It is important to set the page file minimum size and maximum size to the same number for more reason that keeping a tidy file structure. Windows not having to adjust file size dynamically lessens its overhead, resulting in it being slightly more responsive.
- It is possible to set page files on multiple drives. It is my understanding (I could be wrong here, but I think I understand correctly) that 64-bit versions of Windows will use the least active (and, therefore, most quickly accessible) of the page files at the time it needs to write out data. (This was supposedly a feature of 64-bit XP; it was not a feature of 32-bit XP. I don't know if it applies to the 32-bit versions of Vista or Win7.) Assuming this to be correct -- someone please post a correction if I am wrong in my understanding of this feature -- then it would probably be advantageous to keep a 4GB page file on the system drive and a larger one on your second or least used drive. I suspect that experimentation is in order to see if this applies for your applications and usage habits. There could easily be no gain in performance at all and you might simply be wasting drive space.
- Finally, a page file is no substitute for for the real thing. While it is quite possible to create a 16GB page file on a computer having only 1GB of actual RAM installed, you'd be creating a throttling monster. The overhead of keeping track of all the paged data would be so great that your machine would slow to a crawl, defeating the purpose. More actual physical memory equates to needing the services of the page file much less often.
