Can 32-bit Linux use 8GB RAM?
All 8GB of your RAM will be used up, as well as another 12GB of the pagefile. So yes, under 32-bit operating systems, it is more than possible to use up this memory.
Which is better 32bit or 64bit?
When it comes to computers, the difference between 32-bit and a 64-bit is all about processing power. Computers with 32-bit processors are older, slower, and less secure, while a 64-bit processor is newer, faster, and more secure.
Can I install 64-bit on 4GB RAM?
4GB. If you’re running a 32-bit operating system then with 4GB of RAM installed you’ll only be able to access around 3.2GB (this is because of memory addressing limitations). However, with a 64-bit operating system then you’ll have full access to the whole 4GB.
Can Windows 7 32 bit run 8GB of RAM?

Which is better 32 bit or 64 bit in Ubuntu?
Now Ubuntu 32-bit used this patched kernel by default and so it can manage up to 64Gb of RAM. And Ubuntu websites says 32-bit (for machines with less than 2GB RAM) because of RAM usage. 64-bit software use a more RAM than 32-bit.

What kind of RAM does 64 bit Linux use?
2985 MB seems too close to the magical 3 GB mark for it to be purely coincidence, but uname -r prints 2.6.32-5-amd64; clearly a 64-bit kernel, which is all that has ever been installed on the system drive I’m using. The new motherboard is an Asus M5A97 Pro, which has four DDR3 slots supposedly supporting 8 GB modules.
Why does Linux not recognize all the Ram?
At least, Linux has detected it and warns you about it : WARNING: BIOS bug: CPU MTRRs don’t cover all of memory, losing 13295MB of RAM. It also seems that one of your 4 ram module is incorrectly recognised or inserted. You can either report it to your manufacturer, upgrade your bios and change your motherboard.
What kind of OS is Debian 6.0 AMD64?
