System: Abit BH-6 ver. 1.0 CPU: Pentium 3 933@933 mhz (133 bus) Ram: 512 pc100. I put this CPU in and it reports at 933. My AGP ratio is at 2/3. When playing Quake 3 or UT (original), the screen freezes and system hangs. Is my memory being pushed to 133? thx bob |
pushed. Although most memory can handle the push from 100-133, some will
not. The AGP bus setting is only the ratio to the AGP slot, and has no
effect on your memory bus. Your memory is the only thing that is being
overclocked. PC 133 memory should work just fine if you can find it. You
could bring the memory down to 100mhz if the BH6 rev1.0 will allow it. I
don't remember if it will or not, it has been awhile.....:-). Your processor
speed will also drop accordingly.

thanks, Ed I don't think I have memory adjustments. thx bob |
try running Prime95 from mersenne.org . There is a function
called the "Torture Test", and it is a valuable test for
CPU and memory stability. If you can run Prime95 for four
hours, and no errors are shown, then your CPU and memory
are OK. If the program throws an error in a short period
of time, then the memory could be at fault.
If you pass Prime95, but fail while gaming, then the problem
could be related to the AGP slot, or to the video card
(like an overheat problem).
Another test you can run, is memtest86+ from memtest.org .
But I would only use that test, if you are failing
Prime95. If you find errors in memtest86+, only at
consistently the same addresses in memory every time,
it could be the memory is actually bad, instead of
the memory just not being able to handle the speed.
You can also repeat the above tests, with the CPU
set to 100MHz. That would underclock the CPU, but
run the memory at stock speed. At stock speed, all
the above tests should be passing.
For AGP, isn't 2/3 of 133MHz an 89MHz rate ? That
means the AGP slot is running above the normal 66MHz.
I've read, that many older video cards can handle 89MHz
or even higher frequencies, with no problem. It is the
modern video cards (9800Pro for example), that are limited
to 75MHz or so. An older video card may be happier in
this application (of 133MHz, with 2/3rd AGP setting).

You are lucky that so far all you have suffered is system hangs. You are running the PCI bus at 133 MHz/3 = 44.3 MHz which is almost certain to corrupt your hard drive. Your AGP bus is running at 133 MHz X 2/3 = 89 MHz, but that is usually not a problem. If you want to use your current CPU, underclock it with a FrontSide Bus Speed of no more than 115 MHz; that will keep your PCI bus speed below 39 MHz, and prevent hard drive corruption. IDE drives connected to the PCI bus do not do well with a PCI bus speed over ~ 39 MHz; your data and operating system is not safe if the PCI bus speed is above 39 MHz, and keeping it below 38 MHz would be even better. You should run your 933 MHz CPU at 807 MHz or replace it with a CPU designed for a 100 MHz FrontSide Bus (and almost certainly get a 15% overclock) or a CPU designed for a 66 MHz FrontSide Bus and have a good chance at a 50% overclock (Celeron Coppermine.) As you now have your system set up, EVERYTHING is overclocked EXCEPT the CPU. Even though you have only 100 MHz memory, the most likely cause of your problems is the overclocked PCI Bus.

some 440BX motherboards had the 1/4 divider and some didn't. Maybe by
finding a datasheet for the clock generator chip, you could verify
whether 1/4 is there at 133MHz or not.

These threads hint at different revisions of the BH6, having a difference
in the divider department. Looks like "ver. 1.0" is out of luck. I guess
it's 112Mhz for the FSB, instead of 133MHz (as 112Mhz/3 = 37.3 = safe
for PCI).

My brother in law has offered me a slightly later Abit board. A BE2 maybe BX6? |
BE6-II 2.0) are different boards with different capabilities.

Would it be crazy to move my system over to it, keeping my XP OS intact? |

I thought I had heard never to transfer an OS to a new MB, etc? |
relatively easy to transfer an OS install from one physical system to
another. XP's Hardware Abstraction Layer can make it a little trickier, but
even then in many cases where the base hardware on the two motherboards is
very similar.
This is the case here as all the boards you're looking at use the 440BX
chipset. As such you may literally be able to swap the boards round and boot
straight back up. If not, pulling your XP install CD out and running a
"repair" install should see you right.
Before proceeding though you need to find out exactly which board your
brother in law is offering you, and also bear in mind that if either your
(overclocked to 133) PC100 memory, or the overclocked 89MHz AGB bus is
indeed the problem at the moment, swapping to another 440BX based board
won't help.
Where some of the newer boards score is in supporting a proper 1/4 PCI
divider for 133MHz, so if this is your problem, you could be in luck. If
not, however...
