Well, the other possibility is that the kernel gets it right, but fails to export it correctly to userland, thus confusing rovclock. The 200Mhz core clock and 252Mhz ram clock sounds fine and logical. Friendly, Sven Luther -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?

Can you check what the real values are, maybe by using some windows tool on the box, or by hunting the specs of your model on the manufacturer's site or on various review sites ? I don't have windows installed, but I was searching on line these information. I found an article on http://www.anandtech.com/mobile/showdoc.aspx?i=1692p=7 where they claim that M9 (mobility radeon 9000) will have maximum core clock of 250 and maximum memory speed of 230 (that will be effectively doubled been DDR). And these number are somewhat in line with the normal Radeon 900 that comes with a core speed of 250 and memory 200. And the article states that it's likely that on-chip memory will be clocked at 200. If those are indeed the right values, that would definetely explain why I didn't have any problems so far :). Well, the other possibility is that the kernel gets it right, but fails to export it correctly to userland, thus confusing rovclock. I'm not sure how things works there. Does rovclock rely on the kernel, or does it read directly from the video card? I'm not quite sure. If I can help in any way, please let me know. The 200Mhz core clock and 252Mhz ram clock sounds fine and logical. Indeed, the values are so close after all, that I could read them both either way. I guess that's why it took me so long to notice this discrepancy. thanks graziano Friendly, Sven Luther -- +---+--+ | Graziano Obertelli| CS Dept.

Package: linux-source-2.6.15 Version: 2.6.15-1 Severity: minor Hello, I have a radeon M9 in my thinkpad T41 and both rovclock (radeon overclock) and fglrx (when I tried it) reported that the memory speed is 200 MHz and core speed is 252 MHz, while in radeonfb during boot reports the opposite (core is 200 and memory is 252).
