I installed second ram stick to ASUS X51R laptop, and when I boot up in "My computer" properties it doesn't show any increase of memory, same with task manager and bios. But in CPUID it shows both sticks. So why its not working correctly and how do I fix this?
In CPUID shows that both sticks use same voltage only timings and frequency are a bit different. And bios don't have overclock meniu.
And I tried switching them up and one at the time, both of them work alone.
How much memory did the system have, and how much did you add? Speeds?
Which model in specific do you have because it appears that there are different models of that notebook line. Also list the OS.
There was 1GB of DDR2 memory, I added another 1GB. More info about memory is in pictures. I use windows 7 because audio drivers for windows xp doesnt work from asus website and didnt find working ones anywhere.
I don't know how to specify the model more than X51R, so I added some laptop info in the first picture.
As you can see in second picture CPUID shows 2GB of total memory, but in the third picture you can see it says 1GB total memory ("My computer" properties).
Samsung RAM module is the new one, its in the second slot as shown in last picture.
PS. Not all of 1GB memory used because of integrated graphics.
Are both RAM modules in your system identical?
No, only identical thing about these two modules is that they are both DDR2.

That could be the problem...you shouldn't be mixing different modules because doing so will likely lead to incompatibility and stability issues.
So there is no way to make both of them work? And should I keep Samsung module if I leave 1GB?

If you can still return the new module, try purchasing a new kit and then remove your old RAM and see if the issue persists. I'm not saying mixing memory won't work, I'm just saying it's not ideal because of the potential problems that could arise.
Seems like the computer is not Windows 7 compatible as we can see the sound card can never get to work.
Maybe we can try get the latest BIOS from the laptop web site and see if the 2nd RAM can be seen by the windows 7.
Also try install the latest mobo chipset driver and must reboot once.
Then check if the 2nd RAM can be seen.
Hope this helps.
I downloaded bios file from asus website, but i checked and it turns out it already has the latest version installed.
When double checking at your RAM specs, both RAMs are not the exact same speed, 1 is 333, the other is 400mhz.
I would suggest reset the Bios default.
Power on the laptop witout any RAM first, then power ON again with both RAM.
Also do a discharge and see if that helps:
1. remove all power sources including the power adapter and battey, pressing the laptop power button over 20 seconds do not let go, then connec the power adapter only and power on the laptop again.
If still the same problem, we can try install the 32bit system and give a try. Before doing this, we may want to back up data to other extenal HDD first.
Hope this helps.
