Overclocking Radeon 6990m

I notice there is a ton of thread on overclocking the gtx560m, gtx485m, gtx460m but I have not come across one on a radeon or even a gtx580m. Any reason to this? Do higher-end GPU cards cannot be overclocked? Or is it because Radeons are very hot in nature and thus overclocking will just blow them away?

Thanks, I am new to the overclocking scene and have never overclocked anything in my life but while reading it in other threads I find it really nice to try it out.

 

There are a lot of threads and a lot of posts in the owner lounge. For GTX 580M you can use MSI Afterburner. Not sure what they use for the AMD card, but its the same program they use for all the other AMD cards.

You should find something, with ease.

 

I was able to oc my 6990M to 24%. I feel very cool. You need to mod the firmware or use ATi Tray Tools to get the core clocks above 740. I tend to run it at stock clocks was just playing around with it when ocing. My laptop is also used for work so need stability.

You should only oc if you have a GPU bound game, the 6990M is fast enough were most games will run at 60 FPS + , so no reason to oc. Also, some games like skyrim appear to be CPU bound, you can see other posts about that. So ocing the GPU will do nothing for performance in that situation.

 

I tend to leave my laptop stock, or even undervolt to run cooler. Im pretty fearless on my PC but these parts are extremely expensive on laptops to replace.

 

can you overvolt the 6990m. i want to break 17k vantage gpu score

 

Yeah thats very smart. Bunch of hot components in a tiny box... temps will always be an issue. Undervolting is a good idea for longevity.
