Yes. Strangely they both have a different setup, one offers 1800 Mhz speed and the other
only 1000 although they have the same capacity.

Ok, I haven't but perhaps, why not?

They don't? :-(

Here is help. If you don't understand it all quite well you will need to do it slowly and
quietly. :)
To prevent the kernel from swapping to disk (using the swap partition, which
is slower than a swap in ram), install this:
http://meets.free.fr/Downloads/BentoVillageProject/Configurations/System/etc/sysctl.d/50-local.conf
to
/etc/sysctl.d/
this is what it says:
*********
## Configure swappiness
# Uncomment the next line if we are running a laptop
# vm.laptop_mode = 1
vm.swappiness=0
vm.vfs_cache_pressure=50
*********
very commonly adviced in many places on the web, which I use in all my systems since a
while now.
Then the following:
http://meets.free.fr/Downloads/BentoVillageProject/Configurations/System/Zram/
Read the README.
Change your
/etc/initramfs-tools/initramfs.conf
for this one:
http://meets.free.fr/Downloads/BentoVillageProject/Configurations/System/Zram/etc/initramfs-tools/initramfs.conf
what is added is only this:
COMPCACHE_SIZE="25%"
instead of
COMPCACHE_SIZE=""
in /usr/share/initramfs-tools/conf.d/compcache
change this:
COMPCACHE_SIZE="50%"
for this:
COMPCACHE_SIZE="25%"
This is what the patch file means:
http://meets.free.fr/Downloads/BentoVillageProject/Configurations/System/Zram/usr/share/initramfs-tools/conf.d/compcache.patch
and IF you are in a Live,
in /usr/share/initramfs-tools/hooks/compcache
change this:
# Do not use compcache on the liveCD if we have more than 512M
for this:
# Do not use compcache on the liveCD if we have more than 2048M
and after this:
if [ "\${BOOT}" = "casper" ]; then
change this:
if [ "\${TOTAL_RAM}" -gt 524288 ]; then
for this:
if [ "\${TOTAL_RAM}" -gt 2097152 ]; then
This is what is intented with the file
http://meets.free.fr/Downloads/BentoVillageProject/Configurations/System/Zram/usr/share/initramfs-tools/hooks/compcache.patch
