disappointing overclock on 9800 pro
 

Hey

I am alittle disappointed with my o/c on a Powercolor 9800 pro, i know the
Powercolor cards are the not best o/cers but using ATITool its currently
found my GPU @405 and mem core currently @356 i was hoping for at least 410
on the GPU and about 360 on the mem, i have a Artiv VGA Silencer Rev 3 on
the 9800 pro with AS3 so heat can't be an issue, does the AGP vcore have any
effect on o/cing? i currently have it at 1.5v default would increasing this
have any effect?

TIA for any thoughts.

I had been running my 9800 SE at certain speeds for some time with no
problems. I then tried ATITool which found it's stable point at levels
lower than I had been running already. I went back to my original
values and have had no problems since.

Increasing the 1.5v to a higher number will typically have no impact on your
overclock.. It can help stability, though.
Is the VGA Silencer making good contact with the GPU?

Don't rely on Ati-tool too much. Use Radclocker and use real games to check
for artifacts. Your's should run at least at 430/360. That's for sure.

My Powercolor 9600se , with custom Celeron566 heatsink(no-fan), can be
clocked from 325/200 to 380/225 and still be stable.

Yes the VGA silencer is making real good contact i have had it of to make
sure of this and it definately is so can't be that.

I would like to try higher but am concerned about frying the card :( heh

Probably varies from card to card, I've not tries pushing my card to its max,
but my Powercolor 9800 Pro has been running for months at 410/365 also using the
Arctic Cooler (Rev 1)

I know that's the theory, but its not how things work on my rig.

At 1.5v I can get my 9700 Pro to around 380 core. If I increase it 1.6v,
the I can get over 400 without problems. I guess it could be that maybe my
mainboard undervolts AGP a little, and the extra 0.1v just bumps it up to
"normal" level? Dunno. Anyway, for whatever the reason, increasing Vagp
does help my overclock.

That's good to know. I have read about a few folks having some OC success
doing this.
