Virtual memory versus Physical memory size ratio

Just getting a feel for what people have as their pagefile size compared to the amount of RAM they have?

to get things started, I have 8gig RAM and 12gig pagefile. (Yep i know that's a big PF)

The reason for this stems from a recent thread elsewhere on this forum (http://forum.piriform.com/index.php?showtopic=37244&hl=)

i was experiencing long delays with shutting down my PC due to the pagefile getting cleared at each shutdown.

update: i set the Pagefile min to 512m and max to 4g, been running the PC all day, keep checking the size and it didn't go above the initial amount of 524meg.

so far it seems if you have a truck load of physical RAM, you can do with a really small PF.

I typically keep 1.5GB on my 2GB "classic" xp machines.

Unless something is causing me a problem I just go with Windows recommended defaults. The guys that built my operating system know far more about it than I do.

But..but.. once you understand virtual addressing, you'll see why a small pagefile is useful on even big systems. Systems with enough memory that you think you'll never need a swap file. (!)

I've always just left mine system managed.

I prefer smaller PFs. I set mine to 256MB minimum and 4GB max. I have 4 GB RAM. If you are not sure, you better leave it at default values, which is the amount of physical RAM in W7 (to do that stupid memory dumps - which I also have disabled btw).

Having a big PF with 2GB+ of RAM just tends to take up space and it could be difficult to defragment.

My two cents.

Same here.

If someone asks me about this - I do indeed recommend default settings.

This whole PF thing is a hold over from when ram was still expensive.

confirmation.

been running a couple of w7 64bit rigs, one with 8gig RAM, other with 2gig.

pagefile set to custom, min 512meg, max 2gig.

never gone above 512meg.

so it seems if you have lots of RAM (pretty standard these days) the old MS mould of a big pagefile is unnecessary.

default settings, system managed is fine, just wasteful, but huge HD's are also standard, so who really cares. :)

Been using the old 1,5x "rule" with low RAM PCs. I've 8GB RAM and had ~6GB Pagefile (on a HDD, not SSD), but recently changed it to min 512mb - max 512mb and moved back to SSD. Seems to work nicely and doesn't wear out or take too much space from my 128GB SSD.

I've always just left mine system managed.

Me too.

win xp sp3. System managed. RAM = 2.67 gb (should be 3.3, ??) pagefile = ~ 2gb.

The more amount of physical RAM you PC has the less amount of pagefile it needs.

The more amount of physical RAM you PC has the less amount of pagefile it needs.

Yes, it's inversely proportional. When adding RAM sticks you can reduce PagingFile size.

Not to worry about it being undersized cos if your PagingFile is set small, when more space is needed Windows will simply overwrite according to the Least Recently Used page replacement algorithm.
