Yes, I believe it does.  Generally a board that takes unbuffered ECC RAM
also accepts non-ECC RAM.  It depends on the chipset.

What don't you like about it?

Now you've jogged my memory and I'm wondering whether the PSU will be
compatible.  This would need further investigation.  What is the model
of PSU?

My experience has been that 90% of problems are due to power, for all
sorts of devices.

I'm a huge fan of the X9SCM-F.  Sometimes you can even find one that
comes with a 1U chassis, PSU, and fans for not much more than the cost
of the bare board itself.

This is the board I am referring to:

I am compiling inventory of my hardware.  This will take several
additional weeks.

Where are you located?  If it's not more trouble than it's worth (due to
packaging and shipping) I would be happy to donate equipment if this is
useful to you or the community.  Contact me privately if you would like
to discuss this further.  I am in the UK.

However it sounds like you've already got everything you need to
implement a fine solution based on the AMD FX-8320E.  Plus you get 8
real cores, and a configuration that is a little more modern.

This is usually the correct answer.

On the other hand I have encountered situations where increasing RAM can
actually decrease performance, for example :D

I have a similar issue at the moment.  I recently bought an HPE ProLiant
Gen8 MicroServer but I was not expecting to be fleeced like this.  It's
a development server for a personal project.  All of this has been a
major blocker for provisioning the server for what I intend to use it
for (testing Infiniband hardware).

Is this discussion in the list archives?

I can relate to this, with regards to time spent online and money spent.
 As such, I've become very particular about how and where I spend my
time online, and ensuring that hardware I spend money on is actually
working for me in a productive way, rather than merely being an
interesting thing to experiment with.  I already have a a room full of
interesting hardware to experiment with, enough to last me years.
