XP wont recognize RAM..why?

[Joe]

hello.. i recently installed 2 sticks of 512 SDRAM but when i check my
system stats it says that i only have 768 megs RAm .i have reinstalled it
several times ..each stick ..by itself reads 512 MEGS ram but together they
will registar 1024megs RAM when i first turn on the computer but when i turn
off and restart my system then it only shows768 megs ram.. how can i make
my system recognize my ram ?

Don't blame XP - it is a hardware issue. Does your BIOS recognize all the
memory before Windows starts? If the problem is in the BIOS then read the
motherboard manual or check with the manufacturer.

All memory sticks must be of the same type, speed, etc and usually should be
from the same manufacturer. Can you verify that?

How much RAM does your MB support?

Are the 2 modules 100% identical in specification?
What is the specification?
Did you read the user guide as to how to install the RAM?

Certain modules especially the newest DDR2 SDRAM which offers CAS Latency
options 3, 4 and 5 and clock speeds of 200MHz, 266MHz, 333MHz and 400MHz have
specific location in which to be inserted if there are >2 memory slots.


Some mobos require

Use Start - Run - MSCONFIG, go to the BOOT.INI tab, and click on the
"Advanced Options" button.

In the Advanced Options window make sure the checkbox for the /MAXMEM=
line is clear and that there is no value in the data box for that
line.

You will have to reboot in order to put any changes into effect.

Good luck
