Title: Doubled RAM, what next?
Post by: Ryan Sutton on January 13, 2002, 08:34:39 PM

I have swapped a 64mb DIMM with a 128MB DIMM.  Besides restarting SME v5, is there anything I should change with SME to improve performance?  

I am concerned that I had 64MB at install of SME which affected the size of the SWAP partition.  Does it matter?

IIRC, swap is automatically created at 256 MB.  You shouldn't need to change anything, unless your machine doesn't recognize the new RAM (which is unlikely).

Just type free -m from the shell prompt to be sure that SME has recognised the extra RAM... I have had issues with an older motherboard which did not correctly recognise the amount of RAM installed on that particular machine.

If it's *not* registering properly, you'll need to add 'append="mem=128m"' to your lilo.conf to get SME to use the correct amount of memory. (don't forget to re-run lilo after modifying lilo.conf!)

Hi,

take care, that your system caches the whole RAM. This e.g. is not the case with older Mainboards using FX or TX chipset.

I suffered heavy impacts on performance with these MBs after upgrading from 64 to 128 MB.
