Hi all,
I have recently acquired a new Toshiba Satellite A300 that comes with a Core 2 Duo T8100 and a (Mobility) Radeon 3650 HD. Here is the spec. as retrieved using GPU-Z (0.2.8)
Now, my problem is that I use Linux for my day to day work and there is no graphics (and power management) driver for my radeon 3650 and basically what happens is that the fan (which cools the GPU and the CPU) doesn't stop spinning at all. My system gets noisy, hot and it just doesn't feel comfortable to use. I went back to Vista where the fan works properly (that's starts and stops periodically) and I found out that what controls the fan is the GPU driver, that's Catalyst.
I downloaded RBE, dumped the bios and found out that there is table with a set of clocks for every power management policy and I discovered that at boot time, my GPU frequency is about 600 MHz, the GPU RAM is at 500 MHz and the Vcore is at 1.1v, which are the maximum settings for my card. Now, I'd like to change those settings to the minimum so that when Linux boots up, it will inherit those values and thus the GPU will run cool. I don't need the extra 2D or 3D performance under Linux for the moment and I think that's what really I need from my laptop.
So, I went ahead, loaded the original bios and altered the default boot clocks and saved it to another file. Now before actually flashing it, I'd like to have a feedback from you guys, to know if it's OK to proceed (or not). This is the first time I do this and I feel like it's a bit risky. Any ideas?
Regards,
Ilyes Gouta.
