Default Memory Problem or something more sinister?


My laptop only recognizes 3G of the 22G chip sets installed.

I downloaded a memtest .iso and burned a CD on this same laptop.
Seems right after I shutdown the boot I can get things to run for a while.

I booted the CD and ran the test for 5 passes and all tested OK.

I am using a Samsung SSD 500G as my drive if that matters.

I just interchanged the memories to see what will it bring.

I still see
Physical total = 3.47G,
Phys Avail = 30MBytes.
Virtual 2.1G, Virtual Avail = 2.1G
Page File 6.8G
PageFile Avail 2.8G

System managed size for paging.

Process Explorer shows
Idle 90%
SeaMonkey Privates Bytes 150,976K Working Set 61,544K
All others half or less.

Cold Boot.
All back looking normal now runs a few apps I tried.
But, A memory app I have says only 90K of 3.3G is available.
Process Explorer says only 100K of 3.3G available.
I see from Process Explorer that no app using any unreasonable memory.
System Cache 110K


Where else should I look or try ?

Memory fault or something more sinisterÂ* ?



I'd bring up the Task Manager. Right-click the
Task Bar, to start it from a menu.

But your posting already tells us, the answer
is not likely to be in there. You can see in
my sample, I've sorted by memory pigs in Process
explorer, and since you've just started the system,
there would hardly be any regular tasks to eat memory.

The Paged and Non-Pages pools can't do it, because
they are limited in WinXP to a percentage of memory.
If something tried to radically go past the limit,
I think the machine would freeze.

If the video card had developed an appetite (via a
BIOS setting change for shared memory), then your
3.3GB number would be smaller. So that's not it.
Your number is high enough, it's not likely
to be a bus address map issue.

You could run a copy of V5.01 from here, from the
downloads 50% of the way down the page. One pass is
sufficient. One thing to look for, is whether the
numbers shown on the screen when it is running,
make sense (testing 4GB total, perhaps lifting part
of it out of the way, and only actually testing 3GB -
testing is done in 2GB or 1GB chunks).

And CPUZ, the ZIP version would do.

It can tell you what's in each slot of the laptop.

Maybe you have 2x2G installed for example, giving 3.3G free.

You can restrict memory via boot.ini (MAXMEM), but
that "3.3G" number keeps haunting us, as it cuts
off all sorts of misbehavior.

We need a consumer. A consumer that is not
visible in Task Manager. One way to do that, would
be with the (old) free version of DataRAM RAMDisk.
It's a driver level RAMDisk, which means the memory
likely disappears before it's offered as "free". Mine
is set up to use PAE memory, which is why it has no
effect on AWE (below 4GB) memory. Modern versions of
the product, are no longer allowed to munch on PAE
memory, and I think someone had words with the developer :-(
