9800 pro and Doom3 problem

[Robc1880]

I got the VGA Silencer Rev. 3 for my Hercules 9800 pro and was able to put it up to the speeds listed in my sig. I can play Far Cry, HL2, MOHAA, COD, and RTCW without artifacts. As soon as I play Doom3 I get artifacts, is this because Doom3 favors the nvidia cards? Should I use something like radlinker to run my clock lower for this game to get rid of the artifacts? Thanks in advance.

What kind of artifacts are they? If its the only game its not likely that its your clock speeds or temps causing it. I have one and it plays Doom 3 fine, but my 6800 plays it better.

I was getting snow in the game. I haven't tried to slow the clock speeds down little by little yet. I did turn it back to stock and the snow went away. This is why I was thinking about using Radlinker to just set a lower clock when I play this game. Do you think this is a good idea?

Nah, it's that D3 pushes cards beyond all other games.

This is a well known issue for 'overclockers'.

<A HREF="http://www.hardocp.com/article.html?art=NjQy" target="_new">A note on overclocking: it is very likely that overclocked configurations that "play everything else perfectly" will start to show problems on D3 due to new usage patterns. Everyone is of course free to do whatever they want with their own hardware, but don't complain to us...</A>

Even BFG cards with factory OCs experience this problem.

Radlinker or a similar profile manager will be your best bet.

thanks for the help wusy and ape. I will go ahead and use Radlinker to downclock the card until the snow goes away. Should I reduce the core or the memory to get rid of snow? Or should I just downclock both? Thanks again.

From my OC'ing experience (with R9600P not R9800) I get snow/blackflies with memory OC's, but I remember there being some differences between people. I think WS experienced snow with cores, but my experience was memory.

I would suggest trying to back-off the memory first. That's my choice.

It's his core speed. I had the same problem in Doom 3.

Yeah, I get snow with too high of a core clock, too.

Maxtor disgraces the six letters that make Matrox.

 

[TheGreatGrapeApe]

Yeah I was going to utter your name, but I wasn't sure who experienced that. For me it was my memory but I thought the R9800 users were seeing something different, just couldn't remember, it's been a while since WS or even yourself posted some OC'ing experiences. Then again it's been a while for me too :lol: .

Thanks for clearing that up.

thanks for all the help guys, I will back down on the core to fix the problem. Thanks again everyone.

OK well that explains it. I've NEVER gotten snow (knock on wood), I get kalediscope, lock-ups or crashes with core Over-OCs, and either the Blackflies (small for, but plentiful for me) or lock-ups with artifacts on memory O-OCs. To me snow and blackflies were the same effect insteresting to see that they aren't because they sound so similar, and look the same (other than colour) from what screenies I've seen.

I knew others were experiencing different results from mine, but wasn't sure the cause. Perhaps the 0.13 low-k R9600P doesn't experience the same difficulties, does anyone with an X800 series card experience the snow or just lock-ups and crashes?

I need your core may be limited by your voltage, or something like that because on every video card i overclocked i would get snow out of overclocking the core, and MORE snow when overheating until screen is basically snow.

[TheGreatGrapeApe]

While you may be theoretically right, I wouldn't say my core is 'limited' as 400 -> 535mhz isn't a bad OC IMNSHO.

I haven't played with the AGP voltages to boost more, that was another avenue when I was having that friendly OC with GW.

As per GW's influence/instructions I will likely start messinge with this card (I have 2 peltiers that have been sitting in my desk for almost a year) and playing with voltages, etc.

[Robc1880]

so are you saying that I might be able to get rid of the snow by upping the vVPU? I thought that snow meant it was too high of a clock and not a power problem?
