They all overclock about the same, the only difference is the extra features they provide. Radeonator LE is a good no frills o/c utility. For features go for Radeonator 2.0, Rage3d Tweak, etc..
I use radclocker cuz it integrates into the ATI tabs.. I also use RadLinker so I can play every game with specific AA and AF settings without having to manually change the settings for every games.
By some reason I like rivatuner, maybe because I used it before with my GeForce 4 ti 4600, but it does a great job with my R9700 Pro, too. Hey Smradac, nice nick..
\ I like the "low level" aspect of rivatuner- It shows you what the "actual" speed is- Some programs let you set the speed to whatever - then the card automatically goes to the next default speed- You can check that by going into 3dmark 03 and looking at the info - it shows you the "real" speed you are running- That's what I did't like about radclocker- that was the only thing I didn't like though.
I' go with rivatuner too. It's very simple to use, and it does the job easy. Plus, it's updated often.
Can any of you guys tell me where can i dload this overclocking utilities and how much space in megabytes do they take? Thank you P.S.:i was searching on the net for Radeonizer and i found one page that says that developer has stoped working on Radeonizer.
