Virtual Memory

[RobcioPL]

Where should mine be set at? I have 512 MB ram. What should i chose? Custom size? What should be the initial size, and the maximum size? Please help me, thanks.

i belive you set your VM to the same as your onboard mem, so 512mb, or is it half?

What i thought it was 1.5x the amount of ram you have.

If you don't typically use virtual memory, set it to zero. This will ensure that all of your programs stay in memory and don't get "cached" to a page which lies on the disk (no benefit in that).

So will programs actually run faster if you don't have a set pagefile since they will be wholly loaded into the ram?

As long as everything fits in your RAM. Otherwise the OS will have to create your pagefile and move things in and out whilst you're working (whereas starting with a pagefil greater than 0MB will mean you won't explicitly be told the OS is creating/increasing the size of your pagefile).

I run with an initial size of 0MB and a maximum of 150MB and a max of 1024MB.

Typical access time to SRAM (cache memory (generally on the CPU chip)) is between 0.5 and 5 nanoseconds.
Typical access time to DRAM (main memory (RAM to the average user)) is between 50 and 70 nanoseconds.
Typical access time to your hard drive (e.g. your pagefile) is between 5000000 and 20000000 nanoseconds.
