9500M GS flicker with Powermizer enabled When Powermizer changes the clock frequency, the screen fli
  1 / 2    
Hello,
I have an issue with my Acer Aspire 5920G with a Nvidia 9500M GS graphics card.
Every time Powermizer changes the clock frequency of the GPU, the screen flickers one time.

I use Windows 7 Ultimate 64 bit, and have tried both the 186.xx drivers from Acer and the official 195.62 (and 195.81 beta) drivers from Nvidia, with no luck. It also happens in Linux (64 bit Ubuntu 9.10 with 186.xx drivers).

The card does not seem to overheat.

Does anyone know what this might be...?

Typical; When I register here as a last solution to get help, I manage to find the solution myself. Thought I'd write it here for anybody with the same issues.

It seems to be an issue with the 9500M GS and Powermizer with "newer drivers", regardless of operating system.
To stop the flickering when Powermizer changes the clock frequency, I just had to install older drivers.

[b]The 179.xx drivers from Nvidia works great in Windows 7 64 bit.
In Ubuntu, I installed the 173.xx drivers available in the repos, and now all the flickering is gone.

Seems like something was changed after the 180.xx drivers came out.

Hi,
I've got the same problem with my 9500m GS.
It seems it's only in cards with BIOS 60.84.62.00.40.

Probably a solution could be to flash the BIOS to 60.84.69.00.36, but I haven't read yet about someone who didi this with success.

At the moment, I found two solutions to this.

1) use the last drivers without that problem (182.50, they work for me!)

2) follow the instructions at this [url="http://www.hwupgrade.it/forum/showthread.php?t=2000448"]LINK[/url] (italian) to use the latest driver, managing the clock with RivaTuner.

Ok, thank you for your efforts on this issue!

I hardly think the only hope to solve will be I think the only possibility of reaching a solution is that nVidia will apply applies some change on future drivers, changing the mangement of the Powermizer.

or, imho more difficult, the possibility of a BIOS upgrade.

Hello,

I feel the same flickering problem each time PowerMizer changes GPU frequency (performance level).

I'm running Ubuntu 9.10 fully updated on Asus A8Js with GeForce Go 7700, Bios 05.73.22.50.a5, 512MB memory and drivers 195.36.03

After reading this post, I changed the drivers to 185.18.36, which was also available on my machine, and the flickering is now totally gone.

I'm posting this just in case it's relevant information for nvidia to fix the new drivers because I don't know if I'm loosing something by returning to an earlier driver, I mean, apart from the flickering :)

Rgds,
jss

Edit: After a couple of hours, flickering restarted :( Going to try earlier drivers

Hello, thank you for replying.

I went as far as 173.14.20 available on ubuntu repository and the flickering remains.

Then I gave-up and reinstalled newest version 195.36.03 and it doesn't always happen but when it does, it's always a fraction of a second before the PowerMizer changes frequency, as shown by nvidia-settings.

I guess I'll have to live with that /yucky.gif' class='bbc_emoticon' alt=':yucky:' /> , at least until my next buy (ATI ??)

Although it didn't help, it doesn't matter, what really counts and I appreciated, is your attempt to help others.

I couldn't find a similar of RivaTuner for Ubuntu and I also couldn't find your specific driver version on the Ubuntu repository, but I tried all the others available.

Anyway, my situation now is not so bad, that is, I got back to the latest driver version 195.36.03 available on launchpad ppa, and most of the time I get no flickering (about 90% of the time). Sometimes, all of a suden with no cause that I can determine, it starts until next boot.

I hope, one of these days, someone comes up with a solution. For the time being, I'll just ignore it. Thank you again.

To,
lars eivind,
and any other Acer Aspire 5920 with 9500M GS,

Please there is something I want to know about the Acer Aspire 5920 with the nVidia 9500M GS graphics card.

When you upgraded to the 9500m gs, did the card work straight away?
(I'm assuming your 5920's were originally with another graphics card, rather than a 9500m gs.)

I've bought a 9500m gs to use with a 5920 but I get no result at booting. I'm sure that I've been sold a dead graphics card. However I've found this page while checking for 'compatibility'.

The latest 5920 BIOS is installed. The laptop is standard in every other way. When the 9500m gs is put in, the system will not boot. The 5920 blue lights come on but black screen, no bios screen, and definitley no boot occurs. Re-insert the original 8600m gs and the laptop boots happy.

It seems obvious the 9500m gs is compatible with the 5920 because of the posts here. Was it for you, just a straight insertion of the graphics card and "success". [All compatibility pages say this card is ok with this laptop].

Many thanks for your advices if you can take the time to reply.
