stable video card overclock.... sorta

[matt_ramsey]

My video card overclocks perfectly stable at a setting I am satisfied with, but it cannot run Unreal Tournament without major artifacts. I am not too worried about it myself- it runs loops of 3DM2000/2001, Quake III, and all my other less-intensive games just fine and dandy, and in order to achieve stability w/ UT, I have to back the speed down to a point that it's almost not worth it to overclock at all. In fact, if i didn't own Unreal, I would'nt even know about this "problem". So I figured I would ask your opinions on this: are there any hidden dangers that I may not be considering, or am I okay to leave the card running this way? Any one else have experience with a similar situation?

Are you running at AGP4x ?

I was having almost the exact same problem with Unreal
when I first got my Gf2MX400 card.

I turned the AGP rate down to 2x and the problem
seems to have gone away.
I also upgraded to the Detonator 22.40 drivers, and
my 3dmark2001 score went up about 300 points or so !
They also give better FPS in unreal, and seem to look
better.

On my other system when I did some tests, the difference
between 4x and 2x agp was only 20 or 30 points in
3dmark 2000......

i am running at agp 1x, which is about the only way to get newer cards to run on my old BP6 mobo w/o locking up. *sigh*
...wait, i take back my sigh, and replace it with this whimper: *whimper*

is your AGP setting at 1:1 or 2:3

what is your FSB?

perhaps your card is not very overclockable if set at 1:1

[matt_ramsey]

switching between the two doesn't seem to make a difference (fsb @ 78 MHz). I recently noticed some minor artifacts in DVD's also at these clock settings, so I decided to turn them down a little.

just a suggestion...my card will run at 1:1 stable up to 92 Mhz FSB

its an old Diamond Viper V770 TNT2 2x AGP card

looking at your sig: What are you using to cool your chipset? Any suggestions for me

[matt_ramsey]

I'm using a 486 heatsink and a stock fan from an old Slot 1 Celeron 300a. the fan was circle-shaped, and mounted on a big rectangular piece of plastic (the size of the CPU)... so I cut it out so it was just the circle-shaped fan and superglued it to two edges of the heatsink. Just a little something i rigged up out of spare parts. The cool thing is, the fan has a cool shiney hologram on it with the intel logo, so it looks pretty sweet on top of my intel chipset.

are you running that 566 on an adapter? didn't notice you were a fellow BP6 user........

Turn AGP fast-writes off, it can give you artifacts without even oc'ing!!! @ Best it can only give you 1-2% better performance!

yes I am using neo s370 adapter from powerleap...its the only socket370 to FCPGA adapter that I know of and it works realy well
