If you have concerns about RAM, then your first attempt should be
with no add-on groups. Or, if you do try add-ons but run into trouble
then you should try again without the add-ons.
I just tried Fedora-18-Final-RC2-i386-DVD after converting to USB2,0
using livecd-iso-to-disk. My 1.6GHz machine has 1GB RAM, but I restricted
the kernel to 511MB by appending " mem=511m" to the end of the kernel
command line [note the lower-case 'm'.] Switching to VT2 after boot
[type Ctrl-Alt-F2] then "cat /proc/meminfo" showed "MemTotal: 507984 kB",
so I was running as if only 511MB of RAM. The graphics card is
ATI 9250 (9200 PRO) with 128MB. [Switch back Ctrl-Alt-F6 for graphics.]
I had no trouble "Checking software dependencies" with either the default
Gnome3 desktop, or after changing to Xfce desktop. /proc/meminfo showed:
MemFree: 11180 kB
Buffers: 32664 kB
Cached: 269504 kB
SwapTotal: 0 kB
Committed_AS: 483308 kB
and "ps alx | grep anac" showed anaconda with VSZ=219M and RSS=128M.
I did not continue with actual installation because I didn't want
my existing boot configuration (grub1, BIOS drives swapped, ...) clobbered.
I had 2GB of swap space configured by manual partitioning, re-using
an existing linux-swap(v1) partition; but note that no swap had been
used yet because SwapTotal: 0 kB.
So, I would say that 511MB is enough to start actual package installation
for default Xfce desktop. [Last spring I installed Fedora 17 default
Gnome3 desktop complete from USB2.0 using 383MB at 700MHz and kernel boot
parameter " nomemcheck". It took 80 minutes versus 17 minutes
on my 8GB at 3GHz machine. I estimate DVD would have taken around
2.5 hours due to repeated spin-up and paging from squashfs on DVD.]
