Geforce 9500M GS Downclocking Issues

I have my Geforce 9500M GS overclocked to 410/1050/440.
I use GPU-Z to check the temperature and those clocks.
When I was gaming especially GRID for a few minutes, I noticed the clocks dropped to half(from 410/1050/440). The game is unplayable(lag) and I close the game.
I think this problem happen while I change my CPU voltage intake higher.
But if I do not increase my CPU voltage, the performance of my overclocked graphic card would lowered.

For example:
I do not experience GPU downclock when gaming on CPU VID 0.925V but if the CPU VID is 1.0V, the GPU will downclock.

I used Nvidia System Tools to overclock. It is the best compared to other for Nvidia Cards.

 

That's the dark side of overclocking :/. It problaly downclocks itself because of overheat.

 

I do keep watching the temperature while gaming.
It only raised to 67C and it started downclock.
Basically, it runs 70C++ even I do not overclock it and it do not downclock.
70C++ no downclock. Why 67C would downclock?

 

Tehsuigi pls help me T.T!
Bump~

 

Lots of similar issues:

It's definitely not a heat issue.

my 'solution'

 

The "MY SOLUTION" don't have any guides.
It is like Problems solved and that's all. Please guide me. Thanks in advance.

 

My solution was to boot XP instead of Vista.

It worked in my case, but there aren't enough other people who tried it to really guarantee that it will work in all cases.

Also, the problem likely isn't in the overclock. I've been using 580/1200/460 for 6 months now without problems (in XP).

 

The links you provided previously was nearly useless.
Because I do not use any PowerMizer. Those topics were talking about PowerMizer.
Anyway, I do not intend to install XP.

I noticed you did tell about GUI and registry fixing. Izzit for Vista?

 

This is probably due to the additional heat generated by feeding more voltage to your CPU, which causes the thermal trip. The throttling is instigated on the CPU side.
I don't know why your GPU performance would drop when the CPU is undervolted - undervolting doesn't affect performance, only stability.

 

Wrong. My GPU performance dropped when CPU VID is higher.
I know the fact that 6920G would auto-throttle its CPU like a brainless monster.
I fixed it using RMclock by turning the throttle option ON/OFF.

 

All parties (nvidia, microsoft, and the game makers) know this is an issue. It apparently not due to heat or messing with clocks. I installed SP1 for vista 64 and am running a 179.xx series driver and the problem has appeared to go away. I had massive issues with Fallout 3 and Mass Effect and have read others who had the issue with GRID. I know you may take a performance hit with earlier drivers but it may be worth a try so the games are at least playable.

 

Unless you went through the registry to disable powermizer, you most likely are using it, as it is a feature of nVidia drivers. What powermizer does is lower your clocks when you are not using a 3D-intensive application (such as just browsing the web or running a movie).

And yes, the GUI/registry fixing is for Vista (windows in general).

 

...but you said in the first post on this topic that the inverse happened, that GPU performance dropped when CPU voltage was lower.

Ah, whatever. As long as it's working now.

 

TehSuigi is correct. The only time you need an increase in voltage is when you are overclocking your CPU.

Lowering you voltages (aka undervolting) correctly will result in lower temperatures without adversely affecting performance or stability.

 

However, I couldn't find the GUI/registry part of this PowerMizer.
I read the post and it said acer's laptop have different registry structures for PowerMizer.
Do you know where is it?

 

i'm having the same issue. how did you fix it?

 

bump! anyone?

 

hna, please don't bump ancient topics like this one. It hasn't been touched in almost a YEAR!
If you haven't read the Definitive Guide to Throttling yet, do so now.
If the problem still persists (i.e. it's actually GPU-instigated instead of CPU throttling), post in the 6920G Lounge.

 

alright mate, i'll post there.
