I have an old PC at home with 1.5 GB of RAM and as expected its quite slow.
So I decided to install Ubuntu on a different PC. Intel Quad Core and 4 GB of memory, and a graphic card with dedicated memory. I installed the 64 bit version.
I also notice its much slower that running Windows 7 (that was unexpected) and Ubuntu only seems to recognize 2.9 GB.
Ive been searching this forum, I see chat about bad memory and installing 32 bit version. I've run memtest and no errors there. I've made sure I have 64 bit version installed.
What else can I do?
Follow UP: So after the reply from (MrVaykadji – Thanks 🙂 ) here are the results:
speed@testing:~$ arch
x86_64
speed@testing:~$ free -h | awk 'NR>0{arr[$2]}END{for(i in arr) print i}' | grep G
2,9G
speed@testing:~$ sudo lshw -class memory | grep GiB
[sudo] password for speed:
size: 4GiB
size: 2GiB
size: 2GiB
It all seems to me to be 64bit system. What now?!
Please… Anyone knows how to fix this?

To see what architecture (32bits=x86 or 64bits=x86_64) you have installed :
To see the total RAM (in GB) the software-part of the system detects :
To see the total RAM (in GiB) the hardware-part of the system detects :
To see each RAM slot and what does your system sees installed in each* :
note : GB is gigabyte (1000³ bytes, decimal table) and GiB is gibibyte (1024³ bytes, binary table). It's OK to see exactly how much RAM you have in GiB and it also is OK to see a little less than "real" RAM you have in GB. Just saying.
In this example, I use my own system, which :
note: "taille" means "size" in french.
This should help you at first, I'll come back if I think of something else. Hopefully it will be a real answer, this is at most a tip to verify your sayings and what your system sees.
