Please tell do I need BIGMEM kernel?


I have I gigabyte of DDR RAM in Linux Redhat 8.0. Please tell if I need BIGMEM kernel. Or is it O.K to install the standard kernel?

not sure what this has to do with hardware, but a quick google reveals that the BIGMEM kernel is for systems with more than 4GB

I remember a kernel compile option for more than 1 gig, and more than 4. Try it without first?

the bigmem size is different depending on the kernel config. one time i remember seeing the option to change bigmem kernel size minimum ram specs when i was recompiling in xconfig.

default is 4gh, though, only useful for huge servers

With 1 Gb of RAM the standard kernel setting was fine, but I think I did gain a few more Mb by setting the kernel flag


and recompiling. Check you usage with

% cat /proc/meminfo

This shows 1024036864 bytes free for my 1Gb with the above flag. Anyone got a reading for 1Gb and standard kernel?
