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.
