Memory

September 1, 2007

Hi,

I am running 4GB of memory in my system and in system properties it shows up

as 4029MB, I have see other screenshots of people's system properties and

that shows as 4.0GB.

I have no onboard VGA, so where has the remaining 67MB gone?

Re: Memory

Even without VGA, there can be other cards (including ones built in to the

motherboard) whose address spaces result in hidden memory. Given the tiny

bit that you're missing, I'd simply not worry about it. It certainly won't

affect performance at all.

Re: Memory

Ok thanks, the manual says

The following components require memory address space:

a.. System ROM

b.. APIC(s)

c.. Integrated PCI devices, such as network connectors, SAS controllers,

and IEEE 1394 controllers

d.. PCI or PCI Express devices/cards

At start-up, the BIOS identifies the components that require address space.

The BIOS dynamically calculates the amount of reserved address space

required. The BIOS then subtracts the reserved address space from 4 GB to

determine the amount of usable space.

a.. If the total installed computer memory is less than the usable space,

all installed computer memory is available for use only by the operating

system.

b.. If the total installed computer memory is equal to or greater than the

usable address space, a small portion of installed memory is available for

use by the operating system.

Re: Memory

While I am on the subject of memory, what should I set the min and max

pagefile to? I usually do system managed or should I leave it at

automatically manage?

Re: Memory

I would most certainly set those to the same value - this will prevent the

system from having to re-size the file. Personally, I've found page-file

tweaking to have little or insignificant impact on performance, this one,

probably has the largest potential, except maybe putting it on a faster

disk.

Re: Memory

Personally, I would leave it system managed unless you have disk space

shortage. Here is an article worth reading IMHO

Re: Memory

I have found that I usually get the best overall performance

by setting to the recommended 2-1/2 times your physical

memory. Leaving it at the "System Managed" setting will

result in your page file being fragmented as it increases

and decreases in size, and it does cause the overall system

performance to decrease when the page file is being

"resized" and when it is fragmented.

Re: Memory

A comment:

The number for 'Size' is 1.5 x RAM.

Myself - I am not too worried about fragmentation. Here's an informative

document:

http://www.windowsdevcenter.com/pub/a/windows/2004/11/23/defrag_pagefile.html

Without knowing it, I have actually been defragmenting my pagefile like this

for a long time, perhaps explaining why I'm not worried. One other thing it

tought me is to read the disk defrag's report thoroughly. Doing that makes

me even less worried.

The bit about resizing - it's not fragmentation that slows things down

here - it's the resizing operation itself.

I am having a smallish pagefile on the C: drive and a bigger one on another

drive, combining to around 2 x RAM they are all fixed size and I never think

about them anymore.
