Hello all

Since upgrading from BIOS F6 to F7 on the above board I can now run N-Tune.
However, I get the
following warning when starting the programme: 'PCI clock is currently set
to track the HT Bus ... Please check your motherboard manual to find out how
to disable this behaviour'.

Well, I've looked at the mobo manual and it doesn't even mention a link
between the PCI clock & HT bus (I always presumed the PCI slots were locked
at 33 MHz?) so is there a way to have the HT Bus and PCI clock independent
of each other - or is this an integral *feature* of the nforce 4
chipset/Gigabyte mobo?

TIA

BillL

Is that important?
I mean, you dont' need N-Tune do you?
If overclocking and the bios supports same settings, you may
find better results using the bios. For one, you may find
instability before risking OS integrity through crashes or
one of various types of induced memory errors.

I'd suspect that is just a very poor English translation,
maybe even combined with the author (of the text prompt)
not knowing what they're talking about.

It should default to locked. There may be a bios setting to
unlock it (from sync to the front side bus). The prompt
would then not be an indicator of a problem but rather a
suggestion "hey user, if you wanted to run async PCI bus you
can't because it's set to sync'd mode". Typically with
overclocking (clockgen-changing) functions it only changes
the clockgen chips programmed speed but not dynamically
changing ratios or synchronicity to other busses. Support
may be changing in this area, maybe there are new boards now
that CAN change ratios on the fly but I haven't heard of any
yet.

interesting stuff, i never knew overclocking of the PCI Bus was possible, I
knew it was an issue when OC'in, dont know alot about it but am gonna look
for some info on the net for it.

so is the PCI bus slowing the rest of the system down by being set in sync'd
mode? so it would be best to run asychronous?

Alos what effect does the PCI bus have on the running of the system, with
PCI-Express doesnt each slot have it's own dedicated bus? hmm maybe i dont
enough.. lol wouldnt be the first time ;-)

Up until 2 or 3 (maybe 4 now, time sure files) years ago the
PCI bus clock was always raised with FSB, hence the "PCI
divisor" issue with overclocking. Pushing that bus beyond
about 35MHz is a significant risk to PATA hard drive
corruption, and may cause PCI NICs and USB ports to
malfunction as well (among other parts but those problems
commonly appearing at lower overclock than others).

No, it should be in sync'd mode unless you specifically want
to overclock it. Pushing it a little helped throughput in
the past but was risky and is now unnecessary with PCI
Express.

The issue was bandwidth, and PCI Express makes it a
non-issue. It's generally best to leave the bios at default
values unless you have a specific reason to change those.
