I disabled my pagefile haven't had any blue screens
I did have to turn it back on when playing FEAR
edit: well i googled some stuff up
Myth - "Disabling the Pagefile improves performance."
Reality - "You gain no performance improvement by turning off the Pagefile. When certain applications start, they allocate a huge amount of memory (hundreds of megabytes typically set aside in virtual memory) even though they might not use it. If no Pagefile (i.e., virtual memory) is present, a memory-hogging application can quickly use a large chunk of RAM. Even worse, just a few such programs can bring a machine loaded with memory to a halt. Some applications (e.g., Adobe Photoshop) will display warnings on startup if no Pagefile is present." - Source
"In modern operating systems, including Windows, application programs and many system processes always reference memory using virtual memory addresses which are automatically translated to real (RAM) addresses by the hardware. Only core parts of the operating system kernel bypass this address translation and use real memory addresses directly. All processes (e.g. application executables) running under 32 bit Windows gets virtual memory addresses (a Virtual Address Space) going from 0 to 4,294,967,295 (2*32-1 = 4 GB), no matter how much RAM is actually installed on the computer. In the default Windows OS configuration, 2 GB of this virtual address space are designated for each process' private use and the other 2 GB are shared between all processes and the operating system. RAM is a limited resource, whereas virtual memory is, for most practical purposes, unlimited. There can be a large number of processes each with its own 2 GB of private virtual address space. When the memory in use by all the existing processes exceeds the amount of RAM available, the operating system will move pages (4 KB pieces) of one or more virtual address spaces to the computer's hard disk, thus freeing that RAM frame for other uses. In Windows systems, these "paged out" pages are stored in one or more files called pagefile.sys in the root of a partition. Virtual Memory is always in use, even when the memory required by all running processes does not exceed the amount of RAM installed on the system." - Source"
Myth - "Moving the Pagefile to a different partition on the same drive improves performance."
Reality - "Moving the Pagefile to a different partition on the same physical hard disk drive does not improve performance. Simply using a different partition on the same drive will result in lots more head-seeking activity, as the drive jumps between the Windows and page file partitions. Even though moving the pagefile in this case can have the positive effect of defragmenting it, the loss in I/O performance out weighs any gains. It is better to simply defragment the pagefile using PageDefrag and keep maximum I/O performance by leaving the pagefile where it is with a single drive setup. - Source
Notes - However you can enhance performance by putting the pagefile on a different partition and on a different physical hard disk drive. That way, Windows can handle multiple I/O requests more quickly. When the pagefile is on the boot partition, Windows must perform disk reading and writing requests on both the system folder and the pagefile. When the pagefile is moved to a different partition and a different physical hard disk drive, there is less competition between reading and writing requests."
