There are some old boards where memory sticks must be added in pairs

New PC boards do not require memory modules to be installed pairwise,
but they benefit from it. Installing modules in pairs allows them to be
accessed in parallel, doubling the theoretical memory bandwidth compared
to single, or different, modules.

Hmm! Very interesting! I had never heard of that RAID-like stuff with
memory sticks. Does it only pertain the hardware or is the BIOS and OS
involved as well?

I am not a hardware person, but I am currently working on building my
own box from scratch. Any authoritative + good docs (web links or
otherwise) about that stuff? I am mostly interesting on optimizing the
io-subsystem on a X86-based box

Thanks again

You'll get hits if you put 'computer building' into a search engine,
probably most of it is older hardware but it might give you an idea of
what is involved if most of the process is new to you.

If you post specific questions (rather than general ones), you will
probably get better help with the box you are building. Perhaps you might
mention what *you* mean by optimising the io-subsystem. For example,
the following questions. What is it you specifically need to optimise?
When you write something like "X86-based box", there are hundreds of
possibilities and what one might do 'best' will vary from system to
system. Are you trying to build a normal desktop system, a gaming system,
an Internet server? Is there a budget?

I'm not sure why you want to limit to Intel hardware, it is always more
expensive and isn't always faster or more reliable than AMD but it is good
that you have started to narrow your search. If you next pick which Intel
processor, you could start looking at boards that will support that
processor and you will need RAM that will work on that board. Many of the
other decisions will be based on how the system will be used and the
budget. Often people rebuild using some parts they already have and that
influences the decision. The distro you want to use on the system can even
influence things, as some are better at using newer, more modern, hardware
right "out of the box", but that depends on your OS skill.

Note: You will not necessarily get a 'cheaper' computer by building it
yourself, but it is possible to build one that matches your needs better
than one "off the shelf".
