Pagefile location

I have 2 HDD on same controler
1. 120 G ATA 133 with windows on it
2. 30 G ATA 66

1Gig 333DDR RAM

Where should I put pagefile and what size it should be?
 
:) Welcome to NTFS DasBoot!

It is always wise to put the pagefile on you fastest disc, in your case the 120 GB one.
As for the size, it is said that 1.5 to 2 times the size of your physical RAM should be sufficient, you don't really need it since you have a large amount of RAM. But - assuming your using Windows XP or 2000 - Microsoft recommends to have at least 384 MB of pagefile RAM. To be on the safeside (many apps like video-editing software and photosoftware use pagefile RAM) you can set it to 512 MB.
 
Thanks Glaanieboy
quick question is it posible to put whole pagefile or a secondary pagefile2.sys on a RAM Disk?
 
Nope. A page file (or virtual memory) is an extension to your physical RAM, it can only be put on you harddisk.

if you had that much spare ram then disable the paging file and it will stay in the ram anyway wont it. no need for ram disk is there :huh:
 
ahya!!!!!!!!!!!!!!!!!!!


no, you need 4 gigs of ram to run without virtual memory

cheeshe

there are even tweaks for real power users to get xp to use more then the max pf of 4096.

there is no user that will ever speed up by lowering the default size of the pf, and plenty that will slow down...even those with two gigs of ram.

in addition, when xp thinks it has too big a pagefile because you have so much ram, it changes it's algorythim

for instance, if you have two gigs of ram, xp will only assign a two gig pagefile, and not a 3 gig pagefile as 1.5 would suggest

xp has this covered...ms has resaerched, benchmarked, and looked at all these "pagefile improvements".

you will never have a faster computer with a smaller pagefile then the default..

some people will definately have a slower computer if they lower the default

just let the os manage your pagefile, and you will have the best settings.

if you ever see the screen that xp is expanding your pagefile, that's the only time you need to adjust the settings, and you need to make the initial minimum bigger.

NOBODY SHOULD EVER MAKE THE INITIAL MINIMUM SMALLER THEN DEFAULT AND EVERY SINGLE USER THAT DISSABLES EXPANSION IS MAKING A MISTAKE
 
also glaanie, the pagefile is not an extension to your ram, and while this has been used to explain the pagefile, it is a weeK explanation, used in the beginning as the easiest way to explain it to people without knowledge, and it has lead to all this "you don't need a big pagefile if you have alot of ram" nonsense

the pagefile is a storage aea for your ram information.

that's what it is.

figure it out from there, the math is simple

I see a contradiction here...

Though you might know a lot about this thing, I almost have a diploma for it (as a part of Aries A+ training). When your physical RAM is full, the OS copies a part of the physical RAM to your virtual memory and thus freeing up physical RAM.
 
your statment is correct, glaanie..."When your physical RAM is full, the OS copies a part of the physical RAM to your virtual memory and thus freeing up physical RAM."..THIS DOES NOT MAKE IT AN EXTENSION, IT MAKES IT A STORAGE AREA. (your statement is correct, but not complete, as in addition to this informationm the os also writes to disc long before you need to access the pagefile, so that when the time comes that you do put pressure on ram, the transition is seemless...at no penalty in performance)

and some people think the two are synonymuos...they are not.

the os would like to be able to assign an address for however much ram you have installed, as your explanation points out...it does not use the harddrive instead of ram, it stores the ram information, and then brings it back into ram...PLUS, this isn't done untill it's neccessary to do it, and dissableing this function, or reducing the ability to do it in any fassion is counter productive.

xp thinks, heaven forbid, you might use all of the ram you bought to speed your box.

again, the math is simple...let's see now, if I have two gigs of ram, how much area would the os like to have for adress translation?

in addition, some programs request even more memory then written in code, so as to occomodate your future use.

I'm leaving for most of the day.

have fun without me.
 
For size I would just let the system manage it. With 150 GB, disk space shouldn't be an issue.

Another point, I may be wrong here, not one of my specialties, but I think running an ATA 133 and an ATA 66 drive on the same controller will slow down the faster drive to also ATA 66. You may consider if you could change this.
Someone please correct me if I'm wrong.

Also Hi EP and people. I found this place again while looking through a oooollllllldddd backup. I have filled over 10TB and was looking at my collection of antiques. Any bids on the 500Mhz Win 95 fix?
Any of the SP crew still out there?

Impressed you have kept this alive this long EP! So many sites have come and gone. :(

Just did some crude math and I apparently joined almost 18yrs ago, how is that possible???
hello peeps... is been some time since i last came here.

Rest in peace my friend, been trying to find you and finally did in the worst way imaginable.
