I think some went as far as 2400s.

You did not mention your PSU; you should take care of it because you are
gonna put a heavy load on it and you _might_ face the atx melting problem...

I'm thinking to upgrade mine to something like 2400s but I did not make
the step so far because of this problem. From what I've read, I can't
have a clear picture of what makes it burn (seems this is a combination
of "bad/not so good" quality PSU + big CPUs + big graphic card - but
which combination is OK and which is not?)

2400+ is the max, anything faster has a different chip core
use a psu that has overvoltage and overcurrent protection on all lines -
such as an antec
try a big gfx card that draws some of its power via a 4-pin hdd-type power
connector - high-end ati & gf [also old voodoo 5]<!-- ~MESSAGE_AFTER~ -->

How thoughtless of me -- I recently put in an Antec TruePower 550W in, once
it was proven that my 400W wasn't going to cut it anymore.

I cannot begin to tell how many instability problems disappeared into the
ether after that upgrade.

ATX melting problem? Haven't heard about that one. Is that a problem with
the PCB melting from too much current being drawn or something? Last thing I
need to do is melt this thing into a puddle of goo.

Wait... meltdown of the PSU...

I could conceivably put in a second power supply in the case (Lian Li PC-71)
as there is plenty of room. Not redundant supply- second supply. Run some
drives n' stuff off that to decrease the load.

Sorry, read "ATX connector melting problem"...

A few intrepid souls over at the 2CPU.com forums have posted that
they've successfully been running dual XP2800+ Barton core CPUs
on their Tyan s2460 boards. Apparently, the Barton CPUs *can* run
at their quoted 333 FSB, but they don't have any trouble running at
the slower 266 FSB (used on the s2460) as well. The slower FSB results
in a 20% "under-clocking" of the CPUs rated clock speed, however,
it can easily be overclocked back up above the rated speed AND the
Barton CPUs have 512K of L2 cache (twice the old Tbred & Palomino).
I believe these guys have their's running stable at 2133 mHz:

Here are some web pages that show how to add extra conductors to
prevent the notorious "Tyan s2460 ATX Connector Melt-Down":

FWIW I'm running 2 modded XP1700's at 2GHz (2400+)

At post they read as 2000Mhz AMD Athlons.

BIOS is V1.05

Hey Frank,

Have you installed the ATX connector protection mod?
Was it fairly easy to perform?
How is the voltage on the 5 volt lines of your power supply?
