help oc'ing ABIT KN8 ? tia

Had it for a few months. Very stable. I run XP and Linux on it. Temp runs at
35C. Specs in sig. Looking for ideas for basic simple OC'ing. Like what to do
with HT, etc. (~8300 on 3DMARK03)(vid card currently not oc'ed and won't
tollerate much, but it runs at 500/1000, as I recall)(curently 91.47 but may
shift back to 91.31 as "new" settings display doesn't work)(minor)

tia!

Oh, common - I'm far from an oc'ing newbie, but someone must have some

Um, let's see. Drop the memory clock divider, so the memory is not a limit.
Raise the FSB (CPU clock). Salt to taste. And do some research first, to see
what kind of headroom is available on your 3500+. Some people bang their head
against a wall, expecting to get an overclock like some review site, when
it just isn't going to happen.

For me, my overclock removed a bit of hesitation in a game I was playing,
and there wasn't a major improvement. Since you aren't going to beat someone
on the Orb with that hardware, there has to be some performance incentive to
even bother.

Instead of cranking the CPU clock via the BIOS, you can even use Clockgen,
from cpuid.com , and do your clock changing in there. That way, you don't
have to reboot over and over again (or at least reboot less, like when you
need to change Vcore or something).

One thing I would recommend, is connect a boot disk to the computer, that
you can afford to have corrupted. Do _not_ use your regular boot disk,
with all of those files that aren't backed up anywhere. I use a Knoppix
(knopper.net) CD for overclock testing, and disconnect all the hard
drives. You cannot corrupt a read-only CD :-) While booted in Knoppix, I use
a Linux version of Prime95 from mersenne.org and run the torture test. I
load Prime95 from a floppy (it fits).

Say you overclock to 2700MHz, and Prime is stable for 4 hours, then throws
one error. I would back off a bit, like 2600MHz, and run Prime95 and see
if it can run for 12 hours. You want to leave a bit of margin and find the
"everyday overclock" frequency, not the "livin on the edge" frequency. Once
you've dialed it down, then connect the Windows boot disk back up and go to
your regular hard drive config.

Okay, this was pretty painless.
Lowered HT to x4
Freq to 240 instant lock.
Freq to 230 lock after a bit.
Freq to 225 works fine
Left freq at 220

10% speed increase and a 2% increase in 3DMARK03, the latter is to be
expected as it depends almost totally on the vid card.

Why? Well, I'd had it for 3 months and boredom/toy value set in. The only
game I play is NeverWinterNights and the 6600GT handles that nicely.

The remaining question would be whether I am
better off at 220, x4 yielding 880/1760,
or at the original 200, x5 yielding 1000/2000

Any thoughts on that?

Thanks!

HT affects transfers to Northbridge (and more indirectly to the Southbridge).
HT bus is 4GB/sec up and 4GB/sec down. This matches well with PCI Express
x16, which is also 4GB/sec in each of its directions. (Note that an SLI
motherboard with two true x16 slots, does not have enough bandwidth at
the processor interface. Over the long term average, each slot only
gets a x8 share.)

When you turn down HT, you are basically reducing the max rate that
your PCI Express can run at. A PCI Express card works just fine, even
when offered half of the original x16 rate. (Tomshardware did some
benchmarks where they put cello tape on different numbers of PCI Express
lanes, so they could measure the effects.) Dropping your HT from 5x200=1000
to 4x225=900 means an inperceptible drop in 3D performance. You would
notice the difference, if HT was turned down to 1x225.

The Southbridge also shares the wealth. I don't know exactly how bandwidth
is allocated, or what method is used (round robin, isochonous slots, whatever).
Since I've never heard of anyone complaining about disk performance, while
they are gaming, I presume the slower busses get their share first
(somehow). I suppose giving the Southbridge HT priority would solve the
problem pretty well.

You can certainly run 3DMark, change the HT multiplier value (say change
it from 4 to 3) and run with the same processor core speed. That should
tell you whether there is still enough bandwidth left, between processor
and Northbridge, when you reduce the bus speed.

I upgraded my amd64 1.8gig to a 2.4 gig cpu. The difference in
performance was really small. I wouldn't bother overclocking from
2.4 to 2.6 if a 600mhz boost was so minor.

Heck, Newegg was selling a 2.6ghz fx chip cheap using the "amdrocks"
magic word.

I don't trust nvidia chipsets overclocked anyway. Too much data
corruption with them from the old force3-150 on.

Lower HT to keep it within specs. Raise system clock (CPU Freq.) Lower Ram
bus speed. Raise CPU voltage as required/

HT speed is almost meaningless in terms of performance since the memory
has it's own bus. Could be the reason it's locking at higher speeds is
because you are overclocking the ram too much. Lower the base speed of the
ram 33MHz for every 50 you intend to overclock the system clock. You may
also need more cpu voltage. I had to take my old hammer 3000+ to 1.675v
get it stable at 2330MHz up from default of 2000MHz.

I'm surprised that you didn't notice the 600mhz increase, but, yeah, 200mhz
isn't noticeable.

Yep - as soon as you get a cpu, there's a faster one for less. But just
checked newegg for 64FX and cheapest is $200 and that's a lot for a mere
400mhz increase over what I've got. It's still too bleeding edge, price-wise.
When I got the 64, it had been out for a while and didn't cost a lot,
comparatively. Same with the mobo I picked. I'll jump again in a couple of
years (cpu+mobo) when prices are better! Or maybe I'll see a killer deal on a
cpu before then... Realistically, however, I have no, need for the power.
Nice toy, though!

Never experienced data corruption when ocing the xp1700 or xp2600Bart, but
then I tend to err on the side of safety - I find where I stop getting errors
and then still back off a chunk.
