It is.

If 14 used sticks is $50 and 4 new sticks is $120, does it matter? Keep
em as spares, make key chains, whatever.

Under the photo: "Actual item may differ". That photo shows a standard
184 pin non ECC desktop DIMM.

The lot of 14 from Ebay is the only way to go here.

The nVidia MCP61 SB+GPU single chip chipset on this board hit the market
in late 2006 and has been out of production for at least 2 years, boards
using it out of production for a year. Units still in the channel are
simply those that haven't sold. This is the reason this is the cheapest
socket AM3 board Newegg offers.
Sometimes you forget you and I think alot alike. I'd never recommend
anything bleeding edge to you Stephen.

The 2D chip is too slow. If you want to use a GUI desktop and a modern
browser, visit modern complex websites, play flash videos etc, this
system won't be very snappy. You'll also likely need to add a sound card.
This is decidedly an entry level server. Entry is 2-4 sockets.
Midrange is 8-16 sockets. High end is 16+ sockets. There have only
been a handful of high end x86 servers produced throughout history: the
32-way Data General Aviion PPro, the 32-way Unisys ES7000 P3 Xeon, both
long discontinued, and the currently shipping 256-way SGI Altix UV
4/8/10 core Xeon, the very highest of the high end. It's the only
shared memory system of any ISA with over 128 sockets.

Found a good pic of this board. It has an 8 pin aux +12v power
connector, not 4 pin. It may be unused on your system. I.e. the person
who built the box didn't use a PSU with the 8 pin aux output as only one
CPU was installed and most of the PCI slots are empty. I didn't read
the manual thoroughly.
You could probably get away without connecting the 4 pin aux CPU power
on the Foxconn board if using a 65w or lower CPU. I've never tried it.
But I don't find anything in the manual that says the board won't post
with it disconnected. Many newer boards won't power up without it
connected and their docs say so in bold print. This is a safety feature
to keep folks with 80+ watt CPUs from burning up the board traces and/or
smoking the 24pin +12V wires due to excessive current draw.
Worse case scenario if it must be connected, you also buy a $15 PSU with
the 4 pin aux CPU +12V output. It's still a big win over spending $120
to add memory to an old slow box.
Now, if you plan to use it as a headless server, spend the $50 on the
memory and use it as is. Should be fine for some light duty stuff.
