A few days I made a post asking for ideas on the lockups my Visiontek 32 MB
Geforce 2 GTS card experienced when running demanding D3D and OpenGL
applications. Most noteable are NASCAR 4 and GPL. If I had
anything greater than 1X AGP enabled, it wasn't long before the video goes
dark and the audio goes into a repetitive looping noise. The only way out
was to reboot! Even the enabling of sidebanding at 1X made it unstable.

I was running 23.11 drivers, but I went back and tried my 12.41 drivers
just
for kicks. That seemed to help some, but the problem remained and was still
intolerable

It wasn't my CPU overclocking, nor my old BH6 MB not being up to standards,
as some suggested. It was - as Tim White postulated - my power supply not
cutting the mustard! I replaced my 250 w job with a 300 watt unit and all
of my problems have disappeared! I'm now running AGP 4X, sideband
addressing enabled, 2x2 FSAA in D3D and OpenGL (if I desire it) and it
hasn't shut down once in 8 hours of use!

memory at 133 Mhz, giving my hard drive a proper clock, and dogs have even
quit barking at me... I am in total bliss!! :-)

A tip of the hat to Tim White... Tim, this Bud's for you :-)

We have a guy in our TPTCC league who just switched over to a GeForce 2
and was having constant lockups. He finally bought a new fan for it, but it
wouldn't fit, so he used the heat paste included with the new fan and used
it to put the old fan on... The new paste must have made enough of a
difference because he's had no lockups since.

Amazing! What some PC users will go through to push their machines to the
limit. I'm a fiddler at heart, and I just can't resist the temptation to
tinker. I've been through enough grief because of my fixation with it to do
me for quite a while to come. I've been playing musical chairs with
processors for three weeks prior, and then the Geforce 2 GTS issue surfaced.
I can go quietly now though, I've actually exceeded the goals I set 6 weeks
ago. Now it's time to work on doing a sub 1:30 lap at Monza in GPL! ;-)

standards,

Except that, as far as I know, there isn't a BH6 in existence that supports
AGP4x.

Here's as much as I know about that... I'm using Power the GTU tweak program
to achieve this. It is allowing me to select 4X (IOW, it isn't grayed out).
Of course, it may be that GTU doesn't check to see if my MB supports 4X AGP
or not. Whatever the case, I can measure a difference in the performance
between 1X and 4X. Maybe I should select 2X and see if it's any different
from 4X using my benchmark test. If what you're saying is so, I shouldn't
see any (and I'm not saying I doubt you, a 1999 MB may not have had 4X AGP
in mind when it was built).

You are correct, Milhouse. The BH6 doesn't support 4X. Oh well, that's one
less setting I have to fret over - I'm leaving that one at 2X and forgetting
about it! ;-)

I only know this because a few years back I fried an old cpu experimenting
with oc' only, as it turned out, because of a weak ps
I think most of us learn what we know from others' misfortune

Well, try this - it worked with my GeForce 2 MX200 on my BH6. Assuming
you're using anything over a 66MHz FSB (I hope!!! =) set the AGP multiplier
to 1/1. From the look of it on Sandra, AGP1X is 66MHz, 2X is 133MHz, and 4X
is 266MHz. I'm 'overclocking' at a 103FSB (the Celery 900 and WinXP dont't
like even 112FSB with 1.95vcore) and set the multiplier to 1/1...hence, I'm
getting 206MHz, or 'AGP3X' of sorts. =) Best I can do with a BH6...

I've got a C-566 and 667 I'd like to to experiment more with now.... naw -
I won't even go there, I'm at 1200 Mhz now! This was a valuable learning
experience. I hope others will benefit from this; it's now documented for
years to come!

Yep..... 133!

Just when I thought it was safe to go back in the water, you go and give me
more parameters to fiddle with! I can't help myself, I'm off for more
tweaking adventures! I think I follow your logic though. You can't get
your Celery 900 to go higher? Mine hit 1200 Mhz at 1.8v. However, I'm
running W98 Second Edition.

Okay, I couldn't resist... I went and experimented with this. In my case,
the FSB is at 133 Mhz. When I try to select 1/1 AGP/CPU clock, the system
won't boot. It locks up after recognizing the drives and reporting them.
I'm guessing that clock is too much for the GTS. I set it back on 2/3
AGP/CPU clock, and all is well. But in essence, am I not running the AGP
clock at 89 Mhz (AGP 1X)? I'm not really clear on this...

Nor am I, really...but the way SiSoft Sandra seems to report it is that AGP
bus speed set in the BIOS - in your case, 89MHz - multiplied by the AGP
'multiplier'. I think this is the way it works. That way, on a 66AGP,
1XAGP is still 66...2X gives 133, and 4X gives 266. I'm not too terribly
sure exactly how this works either, heh...

I wonder, maybe if in the driver you set AGP4X, then tried the 1/1 trick, if
that would work? This is a long shot, but maybe the driver changes some
multipliers on the board itself as well to go off of the new clock speed...I
dunno, it's a long shot. =)

And yeah, my 900 just won't go past 928. I've even tried the
flashing-at-1.95v trick and I still can't feed it any more than 1.95 Vcore,
and the mobo ignores whatever setting I have on my Asus Slotket.

Ah well, I'm not going to worry about it too much, 928 is quite the
improvement over the old 300a that refused to run 450 anymore after 3
years...and this BH6's days are numbered, at least in my box, as either as a
Christmas or graduation present for myself, I'm gonna throw in a AthlonXP
and some sort of KT266A motherboard. That's what I'd do now, at least, but
I'm thinking I'll probably wait until graduation in May to do it, so
chipsets might change a bit then...

The AGP clock signal is still 66 MHz (or whatever the slot's overclocked
to). With 2x, data is sampled on both the rising and falling edges of the
clock signal, with 4x it is sampled twice again. DDR likewise does not run
at 266 MHz, it is 133 MHz with 2x data sampling per clock cycle. This gives
it *effectively*not *actually* the advertised transfer rate.

Nope. You gets what you gets. On a 2x board that is all you will get, still
2x89 ain't bad-that's what this here Radeon is happily running at. A 1/1 AGP
divider will usually only work at around 100 MHz FSB (if you're lucky) and
below. Overclocking the AGP slot also won't give you much of a performance
gain. Before you start thinking that 66x4 ~/= 133x2, it doesn't work that
way, regardless of what the math may suggest.

Allright, thanks for clearing that one up.

I'm looking at my performance profile under Powerstrip, and I see that it's
reporting a engine clock of 175 Mhz, and a memory clock of 286, fwiw.
That's with AGP set to 2X.... the 175 makes sense.

It didn't.... nothing does diddly when I try to boot with 1/1.

Man, that's too bad. I guess I should feel fortunate that my 900 does 1200
so easily. The 900 seems to be a great overclocker tho, based on the
database at overclockers.com...

I'll probably go with an AMD next, but I'm set for a while now... 1200 gets
me where I want to go and then some with this GTS card!
