I am currently researching motherboards in preparation to an upgrade to my
desktop system in a month or so. Tigerdirect has some low prices on Mach
Speed Viper motherboards. I would like to get opinions from linux users
(Gentoo in particular as that is what I use) If you feel the Mach Speed
motherboards are of poor quality, what would you recommend? What about
Asus, Gigabyte or Abit?
Also, if I go with an AMD 64 processor, will I be restricted as to what
ebuilds are available? If no 64 bit package of an application is available,
will a 32 bit package work with a 64 bit processor, but at a slower rate? I
am leaning toward a Sempron in order to get the best bang for the buck.
This computer will not be used for gaming, just internet, email and Gentoo
upgrades, with occasional spread sheet work and I connect to the internet
through DirecWay satallite. (Hughesnet now)

I should have added, I currently have a 10 year old Gateway computer with a
600 MHZ Athlon K7 and 256 mb of memory, so just about anything WILL be an upgrade.

AMD is a good choice for getting the most bang for your buck. You might want
to research the different socket configurations available for the Sempron
processor. Some of them are going to be more upgradeable in the future, and
would be worth spending a few more dollars on.
I’m not real familiar with Mach Speed, but I see that they offer an upgrade
to a lifetime warranty on their boards, so take that for what it is worth.
Personally, I have been using quite a few AS Rock motherboards for budget
systems, and they have been incredibly reliable for me. Supposedly they are
a sister company of Asus from what I have heard. there are really only a few
brands that I shun. PC Chips is the biggest one, and most of the other “bad
companies” are simply relabeling their boards. You really can’t go wrong
with companies like Abit, Asus, A Open, Gigabyte, MSI, Tyan, etc. Another
company to consider for an AMD system is Iwill. They have some of the best
AMD boards around. My recommendations are to look for the boards that have
all the features you want, then compare prices from there.

You will have the choice of running a 32 bit system, or a 64 bit
system. Not all programs are available in 64 bit versions but you can
solve this by running them in a 32 bit chroot environment. The
performance gain hasn’t been worth the hassle for me, so that’s about
all I can tell you.

Well, I could’ve given you this link in my previous post…
Ken scharf 2012-05-17 18:20:19
There are two ways to mix 32 and 64 bit applications on a 64 bit system.
The chroot jail is one, but it almost duplicates installing the system
twice. A second way is to have two directory chains for library files
so you have BOTH the 32 and 64 bit versions of the necessary libraries
available on the system. Gentoo does this with the multilib (standard)
profile. You can actually install BOTH the 64 and 32 bit versions of
the same application (IE: I have BOTH versions of Mozilla on my system
each with it’s own launcher in KDE.) The multilib method is better
IMHO since it can allow for having a mix of applications open
at the same time.
As for AMD vs Intel, while I happen to like AMD, currently the speed
crown is in the Intel camp with their Core Duo 2 cpus. But unless you
are a hard core Gamer you will probably just be looking for the best
bang for the buck. In this case either vendor wins depending on what
deals you can find.
Asus tech makes good MB but they have had bios problems in the past as
far as Linux support went. (I never had this problem, but it has been
reported). I used to use Tyan, but they seem to mostly support Intel
chips for the desktop and AMD for the server. (No cheap AMD MD’s).
As for where to buy, check out Newegg.com, computergeeks.com,
tigerdirect.com. Also look on pricewatch.com for leads.

Wow, you had an Athlon before AMD had made one? At most your computer is 7
years, 3 months and 8 days old. But as you have a 600Mhz, I think yous is less
(just couldn’t resist 😛 ).
J.o. aho 2012-05-17 18:20:24
If you are using a nVidia graphics card, the IA64 driver is a qutie old
1.0-5336, while for the AMD64 you have the current 1.0-8774, in case you use
ATi drivers, you have only x86 and AMD64 supported. So in the closed source
driver world, AMD will give you a better option.
I like the Phoenix BIOS ASUS usually uses, a lot nicer to use than what you
find on say MSI machines. Of course it could have been nice to see a
OpenFirmware instead of BIOS on an x86 32/64 bit machine (There is a derivate
of OF called SmartFirmware that works on x86 machines too).
Terry 2012-05-17 18:20:27
Well, the truth is I bought this machine used for $100. I don’t really know
how old it is. On boot up, I see something about 1997 in reference to the
bios, so I assumed it was from around that year.

KDE takes several days to compile.
Ken scharf 2012-05-17 18:20:48
OUCH! Well even on my athlon64 3400+ with 1gb ram
it took almost a full day to compile. We’ll try it
again when I upgrade to the X2 4200+ (or maybe the 4600+).
Wonder if GCC will use both cores?
Terry 2012-05-17 18:20:56
One of the cpu’s I am considering is the AMD Sempron 3400+ processor. Is
this what you currently have, if so, would you recommend it? Can you tell
me what the + at the end of 3400 indicates?
Arthur hagen 2012-05-17 18:20:58
No, it will not, but if you put MAKEOPTS=”-j3″ in /etc/make.conf, both cores
will be used for /most/ packages, as gmake will then compile up to three
programs in parallel. I’m saying “most”, because some packages have
incomplete dependency listings and disable concurrent compiling instead of
fixing the g****** makefiles.
(Why use -j3 when you only have two cores? Because quite often one core is
waiting for IO, and this way you avoid having one core idling. Why not -j8,
then? Because it’s wasteful to have too many tasks running at the same
time — the overhead increases for each additional task.)
Ken scharf 2012-05-17 18:21:01
The cpu I have is an Athlon 64, socket 939. It is a 3400+, but you
won’t find such a beast officaly. I think what I have is actually
a sempron as it has a FSB at 1600mhz instead of the usual 2000 for
a socket 939 cpu. (This was a Tigerdirect.com special. Probably
a fallout part or a Sempron prototype as it was made before the
Sempron line came out). I even had to set my Asus motherboard’s
FSB speed back to 800mhz (that’s 1/2 of 1600mhz as it’s double clocked
inside) or the thing wouldn’t boot all the time. The bios defaulted
to 1000mhz. You might have to manually do this for a sempron as well.
Some Sempron’s are 64bit, others are 32bit. Look at the entire part
number and look it up on the AMD web site to be sure. Most socket
939 cpus are 64 bit, all the socket A’s are not, and with socket
754 it’s 50-50. The plus at the end is just marketing. AMD sells
their cpus by model number NOT speed, but it’s easy to find the
The Sempron is not a bad cpu, they are either a reduced FSB speed
version (socket 939), a reduced cache version (256k vs 512-1024k), or

What about distccc, but running on ONE multicore machine?
(or imagine a core duo quad?).
J.o. aho 2012-05-17 18:21:07
Only if you specify a higher -j for make (edit your /etc/make.conf) and that
you have made a SMP kernel. The recommended value for -j is CPUs+1 or in this
case Core’s+1, there are of course a bit different schools here, seen some
that suggest Core’s+2.
J.o. aho 2012-05-17 18:21:09
distcc is a bad solution to take advantage of the second core and result in a
