Re: [LUG] 8GB of RAM in 32-bit machine...

 
I'm no expert but every report and my own experience has been that you cant have 4GB of RAM in a 32bit machine, physically it'll fit but it wont be in use and it's a case of luck as to how much beyond 2GB is registered. The limit is not 3GB per process.

I may have a requirement to stuff an existing server with more than it's current 4GB of RAM - it's running 32-bit Debian Lenny. The mobo will cope and it's a new Intel core-2 processor.

Now, I'm not after a single process with more than the current 3GB limit, but I may need to run several programms which individually want a few GB - hence putting more memory in it - basically to stop it swapping.

(It's a "server" for a specific customer application, so not very general purpose, but it is running "LAMP", but no X, etc.)

However, I've no experience of more than 4GB of RAM in a 32-bit system, so just wondering if anyones done this - basically what I'm trying to do is avoid a complete re-install on the box (which is 300 miles away) with 64-bit Debian (although compiling a kernel to cope with the added memory is fine)

Any experiences? good/bad/indifferent?

Cheers,

Gordon
