Reading the amount of RAM

[Fuad M. Yahya]

I have recently replaced a defective memory stick (256 MB) with a larger one
(512 MB). With that, I should have 1.5GB or RAM. Windows, however, tells me
that I have 512 MB of memory. I have tried each stick by itself, and each
registers 512 MB. I have tried them in different slots, and I have tried
configurations of 1 stick, 2 sticks, and 3 sticks. I get different results.
One time, two of them registered 1 GB, but when I added the third, I got 256
MB! What is going on? What can I do to make it register the real RAM size?
The computer seems to work fine.

All three memory sticks are Corsair. The mother board is Soyo SY-P4IS2, with
Pentium 4 2.0GHz. The OS is Windows XP Professional, with all the updates.
Thank you all.

I'm not an expert but i do know that some computers do not recognize more
than "X" amount of ram depending on age of computer, bus speeds, chips and
all that other technocrap. are you over 2 gigs?

good luck

This mother board can take up to 3 GHz of RAM (1 GHz in each slot). Right
now, I have 526 MHz in each slot, which is half the capacity. The system
supports a single channel of PC133 SDRAM . The system bus speed is 400 MHz.

Any ideas, anybody?

turn the bus speeds to default on the memory and cmos, try again. you may
have to read the board manual for jumper settings.

Have you tried the Soyo site for information?

The system information tool, if that is where you are looking, has a bug
in this area. See what Control Panel - System says at the bottom of he
General page.

Note that Windows is very fussy about mixed modules of RAM. UNless the
match is good you are liable to run into trouble because critical timing
loops do not load in memory of consistent characteristics
