-There are several classic problems related to memory on Linux
-systems.
-
- 1) There are some motherboards that will not cache above
- a certain quantity of memory. If you have one of these
- motherboards, your system will be SLOWER, not faster
- as you add more memory. Consider exchanging your
- motherboard.
-
-All of these problems can be addressed with the "mem=XXXM" boot option
-(where XXX is the size of RAM to use in megabytes).
-It can also tell Linux to use less memory than is actually installed.
-If you use "mem=" on a machine with PCI, consider using "memmap=" to avoid
-physical address space collisions.
-
-See the documentation of your boot loader (LILO, grub, loadlin, etc.) about
-how to pass options to the kernel.
-
-There are other memory problems which Linux cannot deal with. Random
-corruption of memory is usually a sign of serious hardware trouble.
-Try:
-
- * Reducing memory settings in the BIOS to the most conservative
- timings.
-
- * Adding a cooling fan.
-
- * Not overclocking your CPU.
-
- * Having the memory tested in a memory tester or exchanged
- with the vendor. Consider testing it with memtest86 yourself.
-
- * Exchanging your CPU, cache, or motherboard for one that works.
