poolwizard · Aug 10, 2009

Hi guys, i have a computer with only 512 mb, so i decided to buy some new ram, i got it today and bought a 1gb memory, after i put it inside my computer, i switched on my computer and it says 510 mb in task manager 238 mb cached, and 1 free, how come it doesn't show 1.5 gb in the physical memory bit under the performance part? need help, because if i bought the wrong ram , i will refund it

need more system specs!

also did you try to reseat the ram in the motherboard? take it out and put it in again making sure to take your time and make sure it is fully seated.

had a similair problem with my aunts computer, and that fixed it

Hello Poolwizard, and welcome to Vista Forums.

In Task Manager, do you have 510 MB listed as the Total?

What do you have listed as the Installed Physical Memory (RAM) in System Information?

poolwizard · Aug 10, 2009

to alien: yes, on total, it says 510 mb also it says 1.50 gb on installed physical memory (RAM), and 511 mb for total physical memory also how do i put a picture of my system information, i can't click the thing to attach a file

Poolwizard,

You can use the same method here for posting screenshots here.

Using the same tutorial below, check to make sure that Memory is unchecked, or checked and has all of your available memory selected instead.

kk i;' try it, thanks

poolwizard · Aug 10, 2009

so are you saying i can EITHER uncheck it or put maximum memory on it?

i change the maximum memory to 1500 (1.5 gb) but everytime i go on it again, it's back to 512, does that possible mean i bought the wrong ram for my pc?

Poolwizard,

As a test, only have the 1 GB stick of RAM installed where the 512 MB stick is to see if it works or not for you.

ok i've tried it!!!! and now it says 1022 mb on task manager in the performance tab in the total part, should i insert my 512 mb ram into my pc now?

Go ahead and install the other 512 MB RAM stick, but make sure that it is not in a RAM slot that is the same color as the 1 GB stick is in.

What are the specs for each RAM stick? (Ex: speed, timings, voltage, etc....)

You may have two sticks that will not work together. Please fill out your system specs to so that we can look up what type of RAM your motherboard supports as well.

omg thankd you so much, i did the part where they are in different coloured slots,.. And it worked!!!! Thank you so much!!!!!!!!1

Brink · Aug 10, 2009

You're most welcome Poolwizard.

Since your memory is DDR2, it was trying to run the RAM in dual channel mode when they are in the same colored slots. This can only work if the RAM sticks are the same type. Having them in separate color slots allow them to run in a slower single channel mode, but you will be able to use all of your available memory.

If you would like to have better performance, you can dump the 512MB stick and get another exact same 1GB stick to put in the same color RAM slot for dual channel mode and to have 2 GB of RAM.
