Computer not showing all the installed RAM

Someone threw out a computer with XP Home Edition.
Other than a missing front cover, everything works.

It is a Compaq Presario SR1303WM.

Speed supported PC2700 DDR SDRAM DIMM

What it has for RAM.

Capacity 128 MBytes
Memory Type DDR (PC2100)
Speed 133 MHz

Capacity 256 MBytes
Memory Type DDR (PC3200)
Speed 200 MHz

I bought another 256 Mb to replace the 128 Mb, but the computer is
only showing 448 Mb of RAM.

Can someone help me?

Thanks,
Andy

Some people pay extra to look into their case through a transparent
panel :-)

It will take a gig - 512 x 2 - according to HP - some similar Asus mobos
can do 2G.

The mobo has uses 64 meg for the integrated Via video.

256 + 256 = 448 + 64

Does the machine have onboard video? If so, then the 64MB is
probably assigned for that.

The motherboard is ASUS A7V8X-LA, chipset = VIA KM400A / VT8237

http://h10025.www1.hp.com/ewfrf/wc/...442&lc=en&cc=us&dlc=en&product=447312&lang=en

It accepts up to a 1GB module per slot, according to that page.
You could interpret that to mean that at least a low density 1GB
stick would work. And being VIA, chances are if you used a module
with 128Mx4 chips, it would probably work anyway.

And none of that would have any effect at the 256MB level. A 256MB
stick should work no matter how it's built.

A close equivalent to that motherboard (same Northbridge), would
be the A7V400-MX. I downloaded the manual, for a look.

http://dlcdnas.asus.com/pub/ASUS/mb/socka/km400a/a7v400-mx/e1817_a7v400-mx.pdf

Section 2.5.1 on page 46, shows there is a setting called

VGA Share Memory Size [16M, 32M, 64M]

If your motherboard was set to 64M, then 512 - 64 = 448.
You could enter the BIOS, and make that setting smaller.
Mike has already mentioned that. The share size would
affect two things. For 3D games, a larger size would help.
And for 2D operations, the 16MB setting should be plenty
for frame buffers. If you dial the shared memory down
to 16, it's possible some 3D games might not like that,
but for web surfing or email it'll be fine.

If you install an AGP video card, that will stop the
sharing, so more of the 512MB will be usable.

Thanks to everyone for their help.

I set the video to 16 Mb.

John--in a recent trip to Russia, I bought a cracked copy of Windows 7
Final edition. In the past I've not had a problem with my $5 copy of
Vista I bought in Thailand. Do you think I should take a chance
installing it in a new machine? What's the worse than can happen? If
I install an AV program, it should detect any keyboard loggers or
viruses stuff embedded in the OS, right?

BTW--here's a funny one: these pirate software shops in Russia were
selling...cracked anti-virus programs! All for $5 a DVD/CD, the going
rate for all software.

I also got Autocad and a bunch of stuff that would have cost me
several thousand dollars in the USA. Of course I do support buying
legal software and usually do, but I'm not going to spend $1k buying
an Adobe suite of programs I use only once in a blue moon.

If you put the CD key (or serial number) in a search engine and
get results, what you have is worthless. If they gave you a unique
serial/key, then you can probably find a good media to use it
with.

I have never messed with viruses, I just copy out important data,
delete the installation, and then restore a known good copy of
Windows.

Good luck and have fun.

You say "Good luck and have fun" to an admitted software pirate, eh?

Better than somebody who put their own family at risk when stalked by
a crazed cyberstalker, just to win a point on Usenet. Now who would
that be?

One beautiful way to control your computer at will. This is a known fact and
installing it especially from Russia ,you will find a surprise later on when you get
hacked. Bank and every kind of account that you set up including your ISP.

I tend to agree in general, though I had no problems with several
years of using a Vista $5 copy I bought in Bangkok. If I was to be
owned, I'd have known it by now. But still, it makes me pause--
perhaps I'm playing Russian roulette?
