You’ve all probably heard of the LAN (Local
Area
Network)
and the
WAN (Wide
Area
Network).
But some have yet to tap into the most powerful of all networks, the HAN
(Human Area
Network).
This network includes your friends, your personal and business acquaintances,
or anyone else you can go to with questions or problems. The HAN can be
one of your most powerful tools in understanding the world of computers.
Let me introduce myself. My name is Shane Hicks, and I’m an independent
computer consultant and technical trainer, currently assisting my wife
in building her company at Absolute Power Computing. I’ve spent the last
several years of my life working with PC based systems and networks, from
small home systems to WANs deployed across international boundaries for
the military. During that time, I’ve often found that the key to solving
problems isn’t so much that you know the answers yourself, but that you
know where to look to find the answers. You can look in manuals, books,
and even find a great amount of information on the Internet. At the same
time, there is no better source to draw upon than experience and that’s
where the HAN comes in.
The power of the HAN comes in the joint experiences of each member of
the network. The intent of this article is to add an extension to the HAN
available to each member of the Alamo PC Organization. Each month I will
accept questions from the users at large and do my best to answer these
questions based upon my experiences and resources. No question is too stupid?no
problem is common sense until you?ve fixed it yourself a dozen or more
times. I’m willing to field questions from any area of computing, but please
keep my areas of expertise in mind and let?s do our best not to infringe
upon areas covered by already established authors in the PC Alamode.
In answering questions, there will come times when there is more than
one correct solution to a problem. I’m certain that some may even disagree
with my solutions from time to time. That's fine. In fact, if someone has
something of value to add to my answer, I’ll be more than happy to include
their solution in a future article. I’ve never claimed to be a know-it-all,
so I won’t start now. If I don’t know the answer to a question, I may need
to defer to the HAN — but then that’s the whole point, isn’t it?
Hopefully, we’ll all learn together!
To submit questions, please send an e-mail to <PowerTalk@absolutepowercomputing.com>
with “PowerTalk” as the subject-line. Be as specific as you can with your
questions. Without actually being there to witness the problem first hand,
every bit of detail that you can provide is vital. If you are willing to
have your name and e-mail address printed with your question (so that others
may help as we build our HAN), give me explicit permission to include your
contact information in the article. I’ll gather the questions together
and answer as many as I can in the space provided.
With that, let’s start with the first question:

I just purchased a new PC133 rated 64MB 168-pin DIMM and installed it in
my Pentium III 500MHz system. When I restarted the computer, it froze during
the boot process. Why isn’t my system working anymore? |

There are a couple of possibilities.
One thing to remember is that not all memory is created equal. Memory
is sold of varying quality. When memory makers test their chips, they use
a rigorous process. Not all chips pass the tests required to get the name
brand label, but they don?t necessarily fail functionality tests. These
chips are often shipped off to the gray market, sold as generic memory,
and resold at a bargain price. Unfortunately, these chips can be prone
to errors and they can be incompatible when mixed with another vendor’s
memory on the same motherboard. This can cause the boot process to freeze.
Another problem might be speed incompatibility. An Intel Pentium III
500MHz processor is based on the 100MHz front-side bus. Any memory that
came initially with the system is probably rated as PC100. While some motherboards
can accept a mix of PC100 and PC133 memory, others cannot. Some systems
based on PC100 memory will not even accept a single PC133 rated chip. This
can also halt the boot process.

My recommendations:
When possible, use memory from the same manufacturer and rated at the
same speed. With prices as low as they are right now, buy quality RAM from
companies such as Micron or Viking. Finally, you can avoid a lot of compatibility
issues by simply going with the largest single stick of RAM your motherboard
will support.
Well, that’s about all the space I have for this month. We have a powerful
HAN in this organization when we all work together. I look forward to hearing
from each of you and in providing a valuable resource for all our members.
