Nvidia geforce 8400m gs overclock

hey guys, i have been all around google and couldn't find anyways to overclock my gpu.

i tried using rivatuner, but it goes back to its defualt, like it won't stay at the clock speed i choose it at. any1 have any idea for me to overclock my Nvidia GeForce 8400m gs.

any help would greatly be appreciated.


tnx in advance

 

A lot of people have problems with Rivatuner when OCing, try the latest Nvidia system tools here:

It is very easy to use and has a user-friendly interface.

 

alright, giving it a try

 

Make sure you install the driver from laptopvideotogo.

 

i had the driver installed but damn... this also failed, after like 20 secs, the gpu went back to its default

 

Its the drivers, only certain drivers can overclock the 8400 and 8600m GS (mainly HP's units)

Download Dox 182.05 here

what temps do you have?

 

its at 35 C and 95 F

 

dat didn't help flipfire, and moral hazard, gpu-z shows the temp at 46 c

 

Trust me its the drivers when your clocks reset.

Had the same problem on my 8400m GS

 

Yeah, it's the drivers. Try using driver sweeper or something to make sure there is nothing left of the old driver.

 

there is also another problem. when i uninstall the drivers from add/remove programs, and i restart my computer up, i get blue screen, and i have to system restore it.

 

alright, just used driver sweeper, and trying dox 182.05 again, wish me luck

 

*sigh*... no luck

 

Uninstall all ur old display drivers.
reboot and go safe mode and use drive sweeper
Reboot into windows and get the official 186.81 drivers... they run cool and u should have no problem OCing..
get NVDIA system tools 6.05... i had some weird problems with it not working so i use 6.03... get 6.03 on the safe side..
On AC power , then set ur clocks... should have no problem...

 

should i uninstall from add/remove the first time?

 

woah!! wiered! when i run gpu intesive programs, it shows the clocks on my gpu go up! i think this is my speedstep stepping in! so i had the clocks at 600/1200/500, and i ran 3dmark06 test and i got like on average about 10 fps. weired, going to turn of speedstep and try again

 

-.-' it does that on its own its called nvidia powermizer. Speedstep is for your cpu.

 

lol, i'm feeling kinda dumb... ok so i put the clocks at 600/1200/500. do you think it might be able to play blu-ray quaility vids? or 720p hd on youtube?

 

thank you guys for your help, i was doing it right all along, it was just the nvidia powermizer lowering it when not in use.

 

you dont need to overclock it to play bluray. i have 9200m gs and bluray. never stuttered or anything,

 

well thats weired, cuz i have a blu-ray movie, and it plays fine on my other computer, but it stutters in this. i'm using VLC to play it.

 

you can try changing the deviceid to 8600 gs and unlocking pipelines

 

how do i do that?

 

You can ignore that post, its not possible and hasn't been for years now. Nvidia learned their lesson on that.

and exactly two post down ..........Not sure what your trying to get out of this, as I already said this was taken care of years ago, by nvidia soldering off the unused or dead cores that result in a lower end gpu.

A lucky bios flash from another gpu that doesn't brick the gpu being flashed does not mean the performance is increased. gpu-z reads the bios of the card the only things that are usually always 100% right are the clock ratings and bandwidth. Hence why when new gpu's come out gpu-z can only read the clock settings and bandwidth and everything else is usually blank till a update is released.

To OP: don't even try what he is suggesting, best case scenario is you get no improvement at all and a new name for your gpu. Worst case scenario you turn your laptop into a fancy paperweight.

 

haha, lol computer is still repairing. tnx alot guy who gave me the link... but its good, all will be good in no time. and tnx rorschach, if i had continued.... who knows what i might have messed up

 

lol what bios flash?? you change the device id in rivatuner and then change a few bits. worst case scenario is you'll have to reboot in safe mode and uninstall rivatuner/do a system restore

 

actually key001, safemode didn't work out for me. it took me an hour just to fix it.

 

i had an hpdv9740us with a 8600gs and bluray. it was difficult finding an unlocked driver that you could overclock and could play BD's with.
the one i ended up using was a dox 169.xx driver. i think if you look around the net that series is still the best for o/cing the 8xxx series midrange cards and you get BD playback too.
forget the newer drivers as they are not really made for your card.

 

hmm do u still have files for it?

 

its 169.09, i had that for a long time cause it was the only OC'able driver

 

does have really good fps? cuz thats what i need, blu ray movies and good games

 

unfortunately i dont.
but i do think its a dox169.09 good o/c, good temps, goo bd/dvd playbacki used to play medieval total war 2 and batman arkham asylum with that driver on my 8600gs, that was slightly overclocked
dox has his own stickied thread in laptopvideo2go.
youll find it there

be forwarned that the 8xxx nvidia mobile cards can burn themsleves out with o/cing.
be careful and do it slowly and watch those temps always

 

at what temp should i stop the oc'in and chill the laptop? i also couldn't find the drivers

 

nvm, got it

 

thats strange, cos i can use any official drivers with my bluray. i use 186.82 though cos its given me the best results consistantly. it overclocks in nvidia system tools too.
never been able to overclock in riva tuner.

 

ok now i got it to work, it can play blu-ray fine now that my processor is up at its maximum capabilities, what would u guys say is a good clock speed for the gpu?
