hi guys i want to know what page file size is recommended for a 4gb RAM . coz im into gaming and my pc is about 5 yrs old and i just want to know if there is such a thing about a recommended page file size in 4gb RAMS.
i have a :
Operating System
Windows 7 Ultimate 32-bit SP1, 4gb RAM ,and 500gb hdd

thanks for the advice sir leefrost. btw mine is a win7 32bit & 4gb ram not 64bit.
"For W7 in brief:
min size = RAM + 300mb = 3372mb (for 4GB of ram)
Max size = RAM x 3 = 9216mb (for 4GB of ram)"
That info. applies to the paging file of both 32bit or 64bit W7.

When you have your C partition on a conventional fixed hard drive ( drive other than a solid state drive) and you use a Windows managed page file, it creates a situation where fragmentation occurs more quickly. The pagefile gets scattered all over the disk. If file fragments between scattered parts of the pagefile are removed the next file to be written, if it is of any size, is immediately in a fragmented state. This is because the available free disk space is fragmented. Using a third party defragmenter like Defraggler you can defragment free disk space.

Max size = RAM x 3 = 9216mb (for 4GB of ram)
Where did you get this multiplier from?

***Do page files fragment? Yes, they do, but it doesn't matter as long as they are system managed.***If a fixed page file is contiguous at the time it is created it remains contiguous. Page files do not change position on the partition. You do not need to defragment because they are contiguous.
We hold differing views on how to create page files and I suspect neither of us will change our positions. However, I think you should not put a positive gloss in this statement in the way you have. As the fragmented parts drop out of use, they are absorbed back into the drive's free space. It is this occurrence, which leads to free space fragmentation and to greater file fragmentation. The impact of this becomes more pronounced as the disk space on the partition becomes more fully utilised. This is a problem, not a benefit, coming from using a Windows Managed page file.
A common problem I find when looking at System Information files is that many users fail to appreciate how important it is to maintain an adequate amount of free disk space on the C partition. I currently encourage users to have at least 25% free. This can have a noticeable impact on defragmenting and system performance.
Where we might agree is that the benefits of defragmentation are far less material today than they were in years gone by. Leaving aside solid state drives, the performance from conventional hard drives is extremely variable so choosing a hard drive which has better performance benchmark can have a big impact on system performance.
On dual booting:
I never found Windows 8 and 7 to be happy in a dual boot scenario, even in a parallel boot where the two are ostensibly separate. Windows 8 defrag and file indexing were adversely affecting the drive upon which Windows 7 was installed and every switch from 8 to 7 resulted in a CHKDSK being run. So I dumped 7 before it corrupted to the point where it had to be re-installed.
On page files:
I have a desktop tower which has two physical drives. Drive C has a fixed 500mb page file which is enough for DMP files to be created. If you don't have a small page file on C, DMP files are never created. The other drive contains a system managed page file. It all works well.
Do page files fragment? Yes, they do, but it doesn't matter as long as they are system managed. As the fragmented parts drop out of use, they are absorbed back into the drive's free space. It is pointless to defrag page files for this reason..
