overclock ATI X1300 on a Lenovo Thinkpad T60

[korg91]

Hello everybody,

I ask some help from you because I would like to overclock my ATI X1300 on my Lenovo Thinkpad T60 in order to run Gnome Shell flawlessly.

At the moment it runs quite well but animations are not very fluid (I don't remember the correct english word) and sometimes they take a moment to go.

Oh, consider that I have a 1440x1050 display

The dedicated video memory is 64MB.

I don't know if it's useful, anyway here is my lspci:

Thanks in advance

You can't oveclock this card. And even if you could, it wouldn't help much.

Note that even if this card would be an overclocker, you still couldn't do it on Linux, since the drivers don't support OCing.

[korg91]

oh, i see...

so no hope also with rovclock?

and what about making the card stay always at the maximum performance state? does it make sense on my card and is it possible?

[RealNC]

rovclock still works? Well if so, you *can* try, but I doubt it will help anything. An easy way to tell whether overclocking could help with performance is to run the lowest possible resolution (640x480 if Gnome Shell supports that) and see if its any faster.

As for the performance state, run these commands as root:

cat /sys/class/drm/card0/device/power_profile
cat /sys/class/drm/card0/device/power_method

and see what it says. To make the card always run at its highest speed, do:

echo profile > /sys/class/drm/card0/device/power_method
echo high > /sys/class/drm/card0/device/power_profile

[korg91]

andrea@ibm-ubuntu1110x32:~$ cat /sys/class/drm/card0/device/power_profile
default
andrea@ibm-ubuntu1110x32:~$ cat /sys/class/drm/card0/device/power_method
profile

the "echo high > /sys/class/drm/card0/device/power_profile" doesn't seem to have much effect...anyway I should check better...

about rovclock, I don't know if it still works...

setting the resolution at 800x600 gnome-shell is noticeably less laggy...

do you think that a CPU upgrade could help?

[agd5f]

Don't use rovclock. It only ever supported r1xx/r2xx GPUs so it won't work on any GPU produced in the last 8 years or so. Even for the asics it did support, it didn't properly account for the post divider so it only worked on cards where the post divider was set to 1.

[korg91]

so no hope for me and gnome-shell?

it doesn't work too bad but I need it to be perfect...I have no time to wait for lag -.-

(again, what about changing cpu?)

[agd5f]

You might want to profile gnome shell using sysprof or oprofile and see where the bottlenecks are. It could be gnome-shell is hitting a slow path somewhere what could be eliminated.

[korg91]

Ok, I am not able to do that AT ALL, but if you could link me a tutorial or sort of I would be glad to learn

PS: is there any reason why you think about bottlenecks and not just that the gpu is not powerful enough?
