underclock radeon mobile M7

post #1 of 3
Thread Starter 
You got it. Underclock.

A friend of mine has had some serious problems with his Sony Vaio PCGZ1VA laptop. After he bought it in 2003 green lines started appearing Matrix style on the screen. He took it in and got it fixed. Then 2 days later after receiving the repaired unit, same thing. Got it repaired, they said it was the integrated GPU mem that was fried. The third time happened just after the warenty wore out and smartly he gave up on Sony and threw it into a cardboard box.

Fast forward to 2007 and I just traded a spare mini fridge and freezer for it. It has 1GB ram, 60 GB hd, and a 1.6gHz CPU. Problem is still that darned 16 MB integrated GPU. It really looks like the Matrix green things, and they can appear either right from turning it on to 15 minutes into using the system. So it most certainly isn't OS related. When they are going full out, the artifacts make the system unusable.

I noticed the fan wasn't running often. In fact, for the 6 hours I've worked on it, it turned on lightly once. I think heat might be a serious culprit!

I have been unable to find something that will allow me to manually control the fan speed. The software that came with the Vaio seems useless in that respect. I did check for dust etc jamming the fan, all is clean.

Also, I have been looking for graphic issues. Updating the drivers to the newest Catalyst have helped, but not eliminated the problem. So I figured I would try relieve some of the power going through the GPU by under clocking it. Unfortunately I have had little success with either Coolbits 2 or Rivatuner 2. I can't seem to access the frequencies.

I have 3 questions really:
i) I can't seem to find anything that will allow direct fan speed control. I've tried SpeedFan, and no-go.
ii) Overclocking utilities for the integrated Radeon Mobile M7.
iii) Failing that, would I be able to over-ride the GPU with an add-on old PCMCIA GPU?

Any other solutions would be greatly appreciated, too.

Thanx!

Have you tried ATI Tool or POWER STRIP? I know that these tools worked with my old IBM Laptop.

Ah... the laptop is in cooldown mode. I have to wait for it to cool for an hour or so before I can get 10 minutes of use. Then the artifacts pop up again.

I'll try them and post my results. Thanx for your time!
