Overclocking my Radeon 9800 Pro with Zalman Heatsink

[Philippine Mango]

Hello, I'm new to the boards and I have a question. I just bought a Zalman Heasink with fan Model # ZM80D-HP for my Video card and have been overclocking it but I'm not getting what I expected. I have the memory overclocked to 375MHZ and core to 430MHZ but I've only seen an increase of 1000 3D Marks in 3D Mark 2001. Is there something I am missing here? Shouldn't there be a higher performance yeild? Please help me. I'm Running on Catalyst 4.10 drivers.

Meant core!

Thats a respectable overclock on a 9800Pro.

Im not sure whether 1000 3Dmarks is a good improvement or not but Id guess it is. Overclocking graphics cards doesnt really improve scores or performance dramatically although sometimes the performance increase is tangible.

That is a very good overclock for a 9800 pro. You should try 3d Mark 03 or 05, they are more video card dependant.

got my MSI 9800 pro -> XT 128 mb running at a core speed of 470. I´ve replaced the crappy default fan with the boxed one that came with A64 3200+. Darn good cooling I guess.

Heard that o/c the gpu gives better results than the mem, but guess I need something else than the default cooling for those as well. What is recommended? I´ve heard of this articsilver glue somewhat..?

actually I think its the complete reverse, every time I overclock anything I do a very detail analsys of the overclock (simply take screen shots) but I note down what I did at what speeds with all that jazz and have concluded that memory is more important for overclocking. I was overclocking Geforce 2GTS and when you increased simply the core there was barely a performance increase but when you did the memory there was a very large performance increase. Also you want to increase the core when your realizing that the core isn't keeping up with you memory speeds so you should essentially overclock both. Ironically I just RMA'ed this card because it was overheating/screen corruption at DEFAULT speeds and it had never been overclocked before. Soon as I got the board I install the HSF setup and overclock. How do you have your core at 470??? Is your core an R360? I when I got mine back I checked the core and it says R350 🙁 and I never got to check to see if my old card was a R350 or R360! I guess I will never know! Doesn't matter anyways because the day I got it I had problems, for example I would have D3D stuttering in practically every game.
