8500 quality problem

[millsy]

I recently resintalled my OS and setup everything as previous.
However, playing games like Serious Sam has produced lines flickering on/off the screen when movement occurs. It is noticeable in everything including the Demos.

I am using Powerstrip and have overclocked. It is a Radeon 8500LE clocked at 275/275.
I have also installed the Rage3D tweaker to help optimise games. It seems like it isn't refreshing quick enough, but could be something else.
Can anyone help??

what is your refresh rate set to?
if you overclock--please make sure you have adequate cooling. Those tearing lines chances are caused by in adequate cooling.
I changed my retail radeon8500 heatsink to get rid off those tearing when I OCed the card to 294/590.

My desktop refresh rate is 85MHz. Got a good quality monitor which can handle it no probs.

I have not messed with cooling on the card though. You think that may help??

I am using an Antec SX840 with 4 case fans, system temps are constant 23c.

case temp has nothing to do with your radeon8500 gpu cooling.
Even on my retail radeon8500--the quality of the heatsink is much worse than geforce3 heatsink. And also the way the put on the heatsink is the worst.
When I took off the heatsink --I noticed they were usng some kind epoxy to stick the heatsink on--the bad part is the epoxy is about 2mm thick.
try to set your card to default speed first. If when your card is NOT OCed--those tearings are gone. That means you gpt bad cooler.

Put it back and it is better, but still a little is noticable.

Is it easy to change the heatsink and cooling??
