4GB ram limit

 

    Much confusion re: 4GB limit in googling.
    Have 1500MB ram and if I change to 4GB Highmem, what effective ram limit will be encountered in kernel2.6.5?

Re: 4GB ram limit

in the arch stock-kernel i think it's 4gb, but kernel 2.6.x supports much more, if compiled the way to support, so dont worry, just rebuild the kernel the right way :-)

Re: 4GB ram limit

   Thanks for reply!

   The ....(right way)... to configure kernel I am not yet familiar with. (prep)

   The basic question asked was what limit will I incur using 4GB Highmem in kernel but having only 1500MB installed( 896MB if using standard kernel2.6.5 with 1GB as limit of installed ram).

   The answer has to be somewhere between 896 and 1500 but I need to know the expected value of useable ram under those conditions before I go through the effort of changing the kernel only to find out it wasn't worth the pain and suffering.....

   What is the right way to configure the kernel?
