added memory not working

Hello everybody,this is my first post. Please try to help an oldtimer
out. I have an E-MACHINE T1125 desktop. It has a 1.3 GHz
processor and 256 MB
DRAM. Machine has been slow lately so everybody
says add some memory. So I look
up specs on machine and it says it is
expandable to 512 dram. I look inside
machine and see one empty slot for
the memory and think this should be simple
enough. So I go to
and order a 256 stick that newegg guarantees to be
compatable. I get the
new stick and put it into the open slot. Now there does
not seem to be
any differance in speed or anything that I can tell. How can I
tell if
it is working or helping me out?  Thanks much for any replies!

Re: added memory not working

If you have a "My Computer" icon on the desktop right click on it and look at
the properties to see how much memory you have.
Depending on what operating system and applications you are running, 256 MB
might be enough. It might be slow for some other reason e.g. spyware or some
misbehaving application.

You can run a program such as CPUZ, before and after the memory
is installed. It runs under Windows.

It should report the total memory, as well as the
characteristics advertised by each stick of RAM individually.

The chipset appears to be 810E. Chipsets of that generation
are summarized here. The "128mbit" density support, refers to
a memory chip such as a 16Meg x 8 bits wide. A 256MB DIMM
would have 16 of those total on it. 16 times 16Megabytes
each gives 256MB. An important aspect about this particular
formulation of DIMM, is it is referred to as "low density".
If the DIMM has 16 chips and claims to be 256MB, that is
low density. There are also people selling memory with 8
chips, and that is the 256MB high density variety. It won't work
well with some of the older chipsets, and may be "half-detected"
at the best of times.

In any case, none of those details are important for a first
go-around. You should drop back to the original configuration,
run CPUZ and see that it records 256MB total and 256MB on
the single installed stick. Shut down, turn off the power,
and install the second stick. When you boot, CPUZ should see
the total of 512MB of memory, and show that two 256MB
sticks have been detected.

If something is not adding up, as described in the previous
paragraph, then post back what happened.

Whether the system is faster, could depend on the OS.
WinXP would likely be slow and swapping a bit, if it
only had 256MB. It should behave a bit better with

You can use Task Manager (control-alt-delete) to monitor
performance. The "Commit Charge" Peak value, tells you
the what your most RAM consuming moment was like on the
computer, since you last booted. For example, on my
machine right now, Commit Charge Peak is about 1GB, while my
Physical Memory Total is 2GB. That means, some time during
today, I had managed to keep half my memory full. (The
graph shows the current memory consumption.)

You can watch the boot screen while the BIOS counts up the memory

You need memory rated for both PC133 and PC100.  Normally, a 256MB
module with 16 chips will meet this requirement, but there are a few
odd ones made with 32Mb x 4 chips, rather than the more common 16Mb x
8 chips.  For all practical purposes, PC100 compatibility guarantees a
256MB module is made of 16Mb x 8 chips.
