Default Memory question

I have put a new memory stick into my XP x64. I removed two 512 MB
sticks. This new one is 1024 MB. Why would my system still be saying I have
896 MB of ram? Do I need to do something in BIOS? When I had a 1024 and a
512 MB in there it was showing I had 1.3 GB of ram.

How much Ram can XP X64 handle. Only as much as winserver 2003?

Bill

You sure you are NOT using onboard video instead of a video
daughtercard? Onboard video has to get some RAM from somewhere so it
steals it from system RAM. Looks like you are using onboard video and
it is stealing 128MB for its special use.

You might be able to alter the amount the onboard video steals from
system RAM using a BIOS/UEFI setting. The more RAM you allocate to the
onboard video then the better the video chipset will perform. Of
course, that means less system RAM for use by the OS and applications.

Here's some example articles (of MANY you can find in an online search):

https://en.wikipedia.org/wiki/Shared_graphics_memory

Don't know what mobo you have since you didn't give any hardware
details.

Is it reported on the system or do I have to open the tower case. I
don't feel like doing that again right now

Did you buy a pre-built? If so, and unless the sales ticket says you
purchased a video card, you are using onboard video. If you built it
yourself, you should know if you accepted the onboard video or put in a
video card to get better performance.

You can use Piriform Speccy to give you some info on various components
in your computer. There are lots of similar hardware query tools. Even
the age-old msinfo.exe will give some hardware info.

Some PCs like to reserve RAM for whatever. On-board graphics is one but
for example my old Thinkpad T510i reserves 141 MB of RAM even though it
has Nvidia graphics. I could believe it's because Lenovo uses the same
Bios for variants of the laptop that use on-board graphics.

Similar thing with a Dell Latitude E5440, Windows 7 Resource Monitor
shows 95 MB as "reserved" and this one has on-board graphics only.

Maybe you can do something in the BIOS, maybe not. I've gone through the
bioses on these two laptops but in the end the best thing was to put
more RAM in, 8 GB works pretty well for me.

How much Ram can XP X64 handle. Only as much as winserver 2003?


Microsoft says 128 GB for XP X64. For 2003 server 2 GB to 1 TB depending
on variant. So more likely your hardware is going to be the limiting
factor for RAM how much you can fit in and what hardware can address and
not what XP X64 can handle.

See
https://msdn.microsoft.com/en-us/lib...(v=vs.85).aspx
for RAM limits on different Windows variants.

SPeecy says MS-7093 socket 939. It's an old Emachines. As far as graphics it
doesn't say about where it's getting memory from.

I have the manual for that on my K: drive.

E7093v1.6.pdf

ATI RS480/RX480 Chipset
ATI SB400 Chipset

There is no sign of the x32 RAM chip that was added
externally to the Northbridge on some later ATI/AMD
designs. So all the memory used by the graphics, comes
from system memory.

The manual has a few things in it, that seem irrelevant
to the design.

In Advanced Chipset Features, you will find

UMA Frame Buffer [64M, 128M]
AGP Aperture Size [64M]

PCI Express graphics should not have an AGP GART, in which
case such a setting would be ignored. The purpose of AGP
GART setting, is to define a linear region of the address
space, for translations. It allows physical memory gathered
from various places, to have a linear address defined for it.
So the AGP GART is *not* a direct usage of memory. It's
address space. Now, on a 32 bit OS, with a memory license,
defining a large GART chews into the available address space,
so such a setting could have an impact on a 32bit OS with
4GB of RAM present. You would get less than "3.2GB free"
if the GART was actually being used. And my experience was,
that large GART settings seemed to destabilize the computer.

The UMA is the one you should pay attention to.
It only has two options. That's where your RAM went.

The manual also mentions "UMA+sideport", but I don't
see the sideport x32 RAM chip in the motherboard diagram.
The sideport chip was really a "hood ornament", because
it isn't fast enough to "accelerate" the performance
of the video. The reference to "sideport" appears in
only one sentence in the manual.

I cannot see a sideport chip in this picture either.

It is being assigned to on-board video.

There may be a way to adjust that in the bios but you should leave it
alone. I'd just put in the 1024 stick and a 512 stick or else purchase
one more stick of 1024


If you end up putting in two 1024 sticks and there is a bios adjustment
for video ram, I'd actually assign more that the 128 megs currently alloted.

That's it Paul! That's my motherboard. So there's no video settings to
change ? The computer will just take so much RAM then. OK.

Well see the thing is, some computers want the smaller stick in the
first slot. Others the second. Some don't seem to care. And I believe
sometimes you don't mix an old stick with a newer one.
