Motherboard causing freezing

I was aware of this when I bought this motherboard brand new in 2001.
It was intriguing to have the 440BX chipset, due to its known
stability. I also purchased a second SY-6BA+100 board that I've been
using since 2001 and that one just started doing the exact same thing
the past couple days, in a whole separate system! What baffles me is
that it has been very stable until recently in both systems. I am
wondering if running it at 133 MHz for this long may be the problem
like you suggested. One PC has Win 2000 and the other has Win XP,
but that doesn't seem to make any difference. Modifying the bus speed
from 133 to 100 on both systems gets them to both run without a hitch.
Drawback is the processor is now running at 750 MHz and not 1000 MHz
(it is a real 1000 MHz coppermine).

Has anybody else had similar experiences in overclocking the 440BX
chipset from 100 MHz to 133 MHz? Any tips to keep running it at 133
MHz? I've looking around and so far haven't been able to find any
current information.

If not I guess the solution is a 1.0 GHz processor at 100 MHz FSB, or a
newer motherboard like you suggested.

Thanks a lot for the helpful feedback!!

I meant that it might not work initially. If it did work ok
at exact same speed and settings in the past, the chipset is
not the problem. I would then suspect the motherboard
capacitors having failed... check them for signs of
venting... swollen tops, leaky residue on top or bottoms.

You might remove the memory and inspect it, and the board
slot contacts, cleaning them if necessary.

It's been awhile since I've ran one like that, but some
boards didn't have the proper AGP or PCI divider (or both)
so if you were previously using a different video card,
retry that other card. Beyond that the more conservative
bios settings for things like memory timings might help, and
a chipset voltage increase might help as well, though most
boards of that era did not support chipset voltage
increases, AFAIK, and I don't even recall anyone actually
increasing the voltage to gain stability.

newer motherboard like you suggested.

.... or just run it at the reduced speed? I wouldn't put
more $ into a system of that age if you can get it running
stable at 750MHz, as the performance difference relative to
the gains in performance from a new (even budget grade)
system are small.

I did a preliminary check but will do that again. I didn't see
anything yet that looked abnormal.

This board has voltage settings, which I did try increasing but didn't
seem to help. I will try the memory timings as you suggested and see
if that helps any.

Exactly. If I get one of them to work at 1000 MHz (133 MHz bus) again,
I will definitely post back to the group! In the meantime this will
get us by.

Thanks again for the suggestions & help!!
