So Paul or anyone in the know would this increase the hard drive bus
speed. I'm worried about data curruption. Paul to your knowledge this
would increase pci bus? This is a post I found while searching.

This topic is kinda old, but the info I gathered on the web might be
usefull for some people.
Tested on k6-2 500 and tx97-xe rev 3.01 with an unofficial bios from
http://web.inter.nl.net/hcc/J.Steunebrink/k6plus.htm

This bios isn't actually a must, but is shows the real values for 450
and 500 Mhz whereas the latest official beta bios from ASUS can show up
to 400 Mhz which might be a little confusing especially if you are not
sure that you've set up the mobo jumpers right.

All those settigs have been tested using several combinations (like ex.
6x55 or 5.5x50 but also 83x6) and work fine.

TX97-XE

75MHz BUS freq. settings: FS0: 1-2, FS1: 2-3, FS2: 1-2

83MHz BUS freq. settings: FSO: 2-3, FS1: 1-2, FS2: 1-2

BUS ratio:
x5.0 BF0: 1-2, BF1: 2-3, BF2: 2-3
x5.5 BF0: 1-2, BF1: 1-2, BF2: 2-3
x6.0 BF0: 2-3, BF1: 1-2, BF2: OPEN

Vcore 2.2V (important if you don't want to fry your processor!!)
VID0: open VID1: 1-2 VID2: open VID3: open

ATTENTION:

Some other sources show other 83MHZ settings:

83MHz BUS freq. settings: FSO: 1-2, FS1: 1-2, FS2: 2-3
but they didn't work for me

Sounds like a k6-2 400mhz would work in this board or current
overclocked.

Would you advise Paul or others that I don't mess with the FSB to avoid
currupting hard drives I know the proc and ram can take it what does
FSB change exactly on this board

P.S. I really wish I would have known that google would post my email
thought would just show nick need to implement custom email didn't get
one spam tell posted with google groups with gmail account damn I hope
my address doesn't get around.


All I know is:

1) The clockgen chip determines the relationship between
FSB clock and PCI clock. Sometimes there can be two
entries for the same FSB clock, like 120/30 and 120/40 for
example, meaning one clock setting has a good PCI clock
value and the other one has a too high PCI clock value.
And that is why, unless the motherboard manual tells you
the relationship, you'll need to find a data*** for the
clockgen chip itself. Most clockgen chips have some provision
for FSB jumpers, and the clockgen can also be connected to
the SMBUS, when a jumperfree mode must be supported.

2) The PIIX4 Southbridge on your board, is the same one used
with 440BX. You can download the data*** for that (290562)
from Intel. The data*** says the strobes are timed in
terms of PCI clock cycles. And that means there should be
a potential corruption issue, as near as I can tell. Which
means knowing the PCI clock value may help. In the past, a
safe max value seemed to be 37.5MHz. Some stand-alone PCI IDE
controller cards can take a higher value, because the
IDE bus clock is actually derived from a crystal on the PCI
card itself. Thus, on a select set of PCI IDE cards, the
relationship between PCI bus, and IDE bus, is asynchronous.

There was a card you could buy, which would measure the PCI
bus clock. The RD2 here, could measure the PCI clock. But
I'm not sure they make this card any more:

To know more about your board, you have to look up the
clockgen chip next to the FS0-FS1-FS2 jumpers.

I answered most of my own question I got it to work at stock speeds
from searching the web and found undocumented settings. Yay me. Gonna
put on some artic silver 5 and overclock it a bit should go well being
such a low voltage chip.

As far as overclocking go my most important question. Paul or
hopefully someone else can help me on this one. Does the FSB setting
just effect the memory which is fast and newer or the cards and hard
drives also on this board? I think I read yes (cards and hd) but it's
not like modern BIOS where you do it thru software just done via
jumper.

Like on my newer A7V333 the bios and FSB upper setting goes up with pci
bus. I can see it in the bios. Sucks to have that ratio and not
individually might make me choose less stable oc friendly board in the
future.

Hopefully somebody can shed some light on this issue of the FSB on this
board.

Thanks for any and all info appreciated.

Asus Germany used to be the source of some info, which was not hosted
on other sites. In order to make "uniform" sites, the old info
in German, was removed. This archive has a web page for TX97 users.


http://web.archive.org/web/20050205100125/www.asuscom.de/support/FAQ/faq003_p5cpu_supp3.htm

And the whole FAQ list is here:

http://web.archive.org/web/20050323054343/www.asuscom.de/support/FAQ/faq.htm

In terms of bus clocks, the way I would figure it out, is find
the data*** for the clockgen. The clockgen in the motherboard
picture, looks to be the chip next to the FS0-FS1-FS2 jumpers,
and has 32 pins. The icst.com/pdf site has datasheets, but in
some cases Asus got them to make a custom part number, and for
those we are left to guess. (Custom part numbers were used to
try to prevent the manufacture of fake boards.)

But chances are, the settings in the faq003 above, should be
safe to use. For example, I would expect an 80MHz FSB, to have
a 40MHz PCI, but above 80MHz, like at 95MHz, a divider of 3
makes more sense, for a PCI of 32MHz or so.

Hello fellow ASUSers,

I'm trying to find the settings for a k6-2 333 for TX97-XE revision
3.03 says it is supported but no documentation for settings. So I need
settings for vcore for 2.2 and multiplier 5 both undocumented and tech
support had only the info I had from site so don't waste time looking
at ASUS site for manual to answer this question. Closest that is
documented is 2.1 or 2.5 vcore and 4.5 multiplier.

www.cpu-world.com says this chips voltage is 2.2 +/- .1 volt.

Using this box as a firewall with IPcop pretty cool but snort uses up a
lot of CPU resources when both interfaces are watched green and red
gets maxed out and internet speed will be doubling free of charge
sometime in near? future for Comcast users instead of price cut to
compete with DSL.

Well, thanks in advance to any replies or info that could help me.

Best Regards
