![]() You can normally find out the basics from Windows' System applet in Control Panel, or wade through various pages in your BIOS, but here's an easy option for you.ĬPU-Z is a handy 186KB freeware download that interrogates your processor, motherboard and RAM, then provides all the details in one hit. The most important thing to remember is that if any application requires more physical RAM, some of the file cache will be instantly discarded to make way for it, so we don't have to worry about XP cache size as much as many people think.Īlthough many of us use SiSoftware's Sandra utility to provide loads of information about our PCs, as well as running various benchmarks, it's overkill for those who just want to find out what processor and RAM their machine has. This last fact is one that causes a lot of confusion: Microsoft regard unused RAM as wasted space, while many users worry if their free RAM figure becomes low. Any remaining RAM is normally used to make the file cache larger. There is also a non-paged area in RAM for critical code that can't be sent to the page file. Otherwise it sits in the Page Pool in RAM, along with current data pages and the file cache (the vcache of Win 9x), which contains data recently read or written to your hard drives. But data will only be paged out to the page file if you have less RAM than you really need. If one of your applications ever tries to access an address that isn't currently sitting in system RAM, this generates an interrupt called a page fault, and the system then retrieves the address either from an application file on your hard drive or from the page file. Any remainder is stored in the 'swap' or 'page' file (the first term is used by Win 95, 98, and ME, while the second refers to Win NT, 2000, and XP). Since the vast majority of people have far less physical RAM than 4GB, programs are allowed to occupy as much of this virtual 4GB of space as they wish, but with only the active parts actually in physical RAM. An Intel 386 or later processor can address up to 4GB of memory, which the processor manages in 'pages', each of which is 4K in size. The 800MB is a safety valve in normal use the pagefile.sys will remain at a fixed 100MB size.First, we'll have a brief recap of the processes at work. Here are my recommended page file settings for any musician with 512MB or more of RAM. But is this a good idea? Are We All On The Same Page? Some musicians even suggest you can disable the page file altogether, to guarantee no audio interruptions, if you have 512MB or more of RAM. With the rather generous page file default setting you may be wasting drive space, while if you initially make the page file too small, Windows may increase its size at an inopportune moment during recording, and ruin an otherwise perfect take. However, it's still not all plain sailing, and there's a lot of conflicting information about the most suitable size for the Windows XP 'page' file, so this month I thought I would explore the various setup options. Windows XP requires a lot less tweaking than previous Microsoft operating systems to make it suitable for running musical applications, which is great news for us PC musicians using XP. It can also be broadly divided into metals, nonmetals, and metalloids(semimetals).It's a fair bet that many Windows XP musicians don't even know they have a page file, let alone where it is or what effect it could have on their recording. ![]() \): The periodic table is split into seven periods(rows) with the inner transition metals shown separately on the bottom to decrease the width of the periodic table.
