My radeon 9800se OC!

post #1 of 6
Thread Starter 
I received my 9800se today!,
at first i was very disappointed to find out that i get the "checker-board" artifact when running the card with all the 8 pipelines enabled, nothing i tried
seemed to help, including forcing AA and AF, and disabling Hyper-Z using Rtool version 0.998 RC 11.
Then i decided to try to overclock, i easily hit 450/740 using ATI tool without raising voltages on stock voltages... Original clocks were 324/580
Not a single artifact during Aquamark 3 or ATI tool stress test(for a couple of minutes)...
Then i runned the card with all the pipelines enabled with those clock speeds,
there was minor artifacts beyond the checker-board artifact...
Any way it did increased my FPS during the major loads... but only raised my score by approximately 5K, which is exactly the original improvement i experienced due to the OC.

Hmm. You'd think that it would be able to use all 8 pipelines since its meant for that. Try running all 8 while stock and then doing it up? Or is that what you did? Your OC might be a little high and that causes artifacts. Try downloaded Omega drivers and using their oc'ing tool, maybe its the ATI tool, what version are you using?

I'm no OC newbie...
I have tried unlocking the pipelines and running at stock.
First i downloaded the patched ati2mtag.sys driver file and replacing the original with it, reboted, all seemed to be alright but my computer crashed after several seconds(Instantly turned-off).
Then when i eventually tried to actually play i got the "checker board" artifact...
I also tried to install the whole modified driver... no good.
Then i tried to run OC, and i was amazed to hit 450/780 stable without a single artifact.
I'm using ATI tool 0.24...
And tried to unlock the card with the latest softmod software from sodtmod.techpowerup.com

Was also wondering about the function of the two switches nearby the heat sink, can provide a photo if its necessary.

The answer is simple, I can reach 450/390 because i only have 4 pixel rendering pipelines, and you have 8...
That probably the balancing factor...
