Overclocking GT435M(and the alikes)

Well, repasting seem to have worked well, figured it's time for some power boost. Searched up on how to OC GPU using softwares.

After a few searches and tries, ATItool is completely outdated, had no idea how to work coolbit, found a nice guide for rivatunner, but the "customize" button next to "forceware detected" won't show up.

Anyone with experience overlocking recent nvidia cards would like to give me a hand on this?

Edit: sorry for the typo, meant to say GT425M on the title.

 

Just overclocked my GT 420 myself on my Dell XPS 15.

This is what I use: NVIDIA DRIVERS 6.06
It integrates itself with the nVidia control panel and it works very well!

 

That's very neat and easy to use, thanks for sharing!

OCed graphic clock to 750 and memory clock to 960, increase my 3dmark06 score by 2000 already ;O

 

No problem and nice overclock! Only thing is I wish there were way for the clocks to save and be set to default for the laptop.

Care to share temps and 3Dmark scores? I'm stable at 740/960 with a GT420m. I average around 8466 with 3Dmark06. Temps wise, I average around 76-78 degrees.

 

When you exist it asks you if you want to load the setting at start up, that should do the trick(unless you're talking about something else?)

Did a few more test and set mine to 790/960 as final. 800 will not start 3dmark06, but 790 ran through it smoothly. Final score was 93xx.

How do you check temp while running 3dmark06? I'm pretty sure it never passes 70 though. Been monitoring it with GPU-Z with ~97% GPU load for 20minutes now(running the 3D image from ATITool) , Highest temp is 60 and usually steady at 59.

CPU temp on the other hand has been around 67.


Edit: Ah nvm, everything reseted to default after reboot. Oh well, at least a few simple clicks gets the job done so it's not too bad.

 

Is there maybe an nvidia driver we can use that integrates the overclocking into the driver it self? Im sure we have it but dell just locks it.

 

Just figured out how to set it to default:

1, Go to device setting, configure your setting, save it to a profile.

2, Go to profile policies.
2a, under "take this action", check "load this profile"
2b, under "when the following conditions is/are met", high light(click) "the system first starts windows"
2c, click the -> button
2d, click "load this profile" to the right of the -> button, select the profile you just saved
2e, click accept

3, Done!

 

I just got my XPS with 420M, what rates would y'all suggest I should OC my card to? (A reasonable OC rate, Not to the point it will heat up and shorten its lifespan of course)

Additional question: If I OC it to the rates of 425m or 435m, will it shorten its lifespan?

 

I'm running at the highest clock that will not fail 3dmark06. Heat difference is minimal, the bottle neck is the card itself.

I have no idea if it shortens its lifespan or not, but I'm guessing it would, since you're making it do works "harder and faster".

OC it to the rate of 425M won't be any significance change, it's only 60MHz more(500 > 560). 435M runs at 650MHz. ClearIzzy is stable at 740/960 so you might want to give it a shot, you're OC either way, might as well shoot for the best.

 

Awesome thanks a lot! I'm quite lazy to do the clocks over and over again

Really nice overclock and solid score. So dang close to the 10k mark!
I usually don't check temps with 3DMark06 since I use furmark as my main stress tester which has a built in monitor and plus I use HW Monitor. Wish I had your temps

Congrats and welcome to the club! I started out with trying to hit the 425m's clock and memory speeds. If it was stable then I upped it to the 435m, eventually making my way around GT540m and GT550m speeds.

In terms of lifespan, the 420m's have the same shader pipelines + architecture as the 425, 435, 540, etc. Nvidia has a habit of rebranding and pumping out the same card. As long as you have sufficient cooling, test to make sure the card is able to handle the overclock (all video cards overclock differently), and you don't play with voltages it'll be fine.

 

Cheers guys, will try it on 425 and 435 speeds first.

 

I have a few questions about overclocking.

Does overclocking destroy the warranty? And how much can you usually overclock by in terms of %?

If I was to overclock my graphics card to 400% (or something far too high), then would the card keep going till it broke, or would it switch off when it got too hot to avoid breaking?

Thanks

 

i THINK it might destroy ur warranty but idk how they can prove that u overclocked because its mostly software based.

overclocking really depends on the card itself. theyre not all made equal, for example, the 420m ,425m, and 435m are all the same chip however, the 435s are rated to be better quality and able to withstand higher clocks and stay stable. most of the time u can get maybe a good 30% increase in clocks but be careful.

and the card usually has a temperature threshold. if it hits a certain temperature, it might either shut down or downclock (video cards have different clock speeds, one for low power stuff and one for high performance stuff and u generally OC the performance clock).

 

You simply cannot do it. Each card has its own capability limit and if you go over that, it will restart(screen blacks for a second and comes back up telling you GPU crashed)/freeze(when you OC way to much screen blacks and never come back up, you have to force reboot) itself. This is what I observed OCing my 425m with nvidia, not sure if it holds true with other cards/softwares.

 

Like conscriptvirus said, percentage-wise it all depends on the card.

Now, for warranty. If you're doing software based overclocking and the card goes south then there isn't a way to prove that the card died due to an overclock. So your warranty would be still intact. Software overclocking is pretty safe. The only time you'll get problems is if you do an extreme overclock that the card isn't able to handle. You'll get fun things like: image tearing, artifacts, and if its a heating issue then the card would shut itself down as a safety measure for both you and the card.

 

Im running my GT435m on GT550m clocks for over 2 months without issues.. temperatures are the same and no artifacts. This card gives you enough room to play around and the temperatures never go above 69º celsius after playing for a few hours. I don´t need to bump up more the clocks once all the games that i played are maxed out and run without troubles in good frame rates. One day if i have problems running a game i will play around the clocks again. Its just a shame that this card doesn't allow bios editing at least for me.. anyone with better luck?

 

Today I had some free time so I played a little bit more with the clocks.. I bumped them to 780/960/1560 and I achieved on 3dmark Vantage 4902 points for the gpu. No artifacts, very stable and temperature difference from stock clocks only 3 degrees

 

69 C is very low! I have the same card (not OCed) and the temps go above 80 C after gaming. Have you repasted yours?

 

No, I haven't repasted mine. I've got new temperature of 76 degrees after playing starcraft2 for 2 hours..

 

My 425M OCed to 790 has never ever passed 65 degrees after hours and hours of avtive WoW play(or anything else for that matter). I did repaste it with AS5 though.

 

what are you guys using to overclock? ati tool? riva tuner?

 

i use nvidia inspector since it lets u make shortcuts on ur desktop for different clocks.

 

Just the nvidia tool mentioned by ClearIzzy on page 1. Set up some profiles and a few "rules" and it will change the clock automatically according to your need. Very nice and neat.

Edit:

Just tried Nvidia inspector, this is the one to go for if you're looking for extreme OC, since it unlocks max clock limit. I'm able to run the mem clock 100 Mhz higher than the previous max, still trying for higher value before it'd auto crash.

Edit2:

Got the mem clock to 1080(any higher will start producing funny artifacts) and finished 3dmark06 smoothly, with the final score of 9811(so damn close the the 10k mark!), wish my core clock would go higher but 790 seems to be the absolute maximum before it gets unstable. Temp maxed out at 65. Thanks for sharing Nvidia inspector, conscriptvirus, highly recommended if you want to get every single possible bit out of your GPU.

The "create clock shortcut" option is also very handy as a simple double click gets you the clock you want.

 

The temperatures can vary depending on your room temperature too. When i play in my room i get max 76º celsius and when i play in my office i just get max 69º.
Looks like that the maximum clocks for my card are the same as Neubeehunhun 790-960-1580. Don't want to rise anymore the memory clock..
I wonder what will be the maximum overclock that the owners of the GT550m will get..

 

You are not running 3dmark06 at 1280x1024, are you?

I can OC my gt 435m core speed to 810 and it goes through 3dmark just fine, but it's unstable in games, 800-805 is a much safer freq.
However I'm getting artifacts with memory clock as low as something around 920, but found out that raising memory clock doesn't affect 3dmark score that much (compared to core frequency).

Btw. your 65 temperature is phenomenal, whats the secret? Care to post a screenshot with 3dmark window and some temp monitoring software that had been running in the background?

EDIT:
or not 3dmark screen, just furmark window doing burn in test, as far as i remember it displays gpu frequencies and temperature, I would appreciate it much, furmark is free and small to download.

I would kindly ask you too, hvieira, for furmark screen.

Thanks.

 

How come I don't have the option to run at 1280*1024? It defaults at 1280*800 every time I open it.

Is it because mine is not the free version? @_@



I monitored the temp using gpu-z. Check log to file before I start the test, and scan through the file afterward.

My secret? There really is non. All I did is a repaste with AS5; also removed the 4 dust filters on the bottom; have a 9cell battery; room temp, I don't have an exact number, but it should be anything from 21-25C.

I will give furmark a try

Edit: How should I configure furmark settings, everything default?

 

The only way for you to run 3DMARK06 in 1280*1024 is to plug a monitor to your laptop that supports that resolution once your laptop doesn't support it..

 

I will be able to do it in a few days once I get my HDMI cable to connect it to my HDTV. But I ran it at 1600*900 and the max temp recorded with gpu-z is still 65, score dropped to 8740.

Mess a bit with furmark, weird everytime I take a SS it will show up as
http://img145.imageshack.us/img145/6030/furmark1.png

Max temp slowly raised to 74 in a 16 minutes burn in test. Full screen, 1600*900, only dynamic background was checked as default.

 

Furmark burns my gpu to 95*C, and i got my heatsink repleaced a couple days ago btw, so it runs on stock paste though. Planning to repaste tomorrow.

That screenshot of yours looks like just the first frame of the process, maybe try windowed mode? i wouldn't care about settings cause it is the temperature graph that matters.

You have xps 14 right? maybe it has a better design, or maybe the gpu is different, beacuse i don't see a possibility that just by repasting i could drop 20*C.

And just for fun (note it's 1280x720):

 

Screen shot worked in window mode, running it again.

How long did you run it for?

And yes mine is xps 14

Edit:

 

Big thanks for the screen, I'm jealous ;P.

 

No problem, hope you get a lower temp after repasting

 

I noticed that your card is going on 0.9V while mine has 0.96V, that causes some temp difference and also allows me to get higher clock freq.

My non oc furmark:



And oc'ed:



Btw. there is some monkey bussines with 96*C temp, it's interesting that so many people mention that temp. isn't it? Also I've seen my card going higher than 96 so its not the max temperature or something.

 

My max voltage is locked at 0.9V and there's no option to unlock max. It does allow me to under volt it to 0.83 but it will reset back to 0.9 as soon as I click apply.

 

Temperatures measured on my room with temperature of 25º celsius..

 

Does anyone has 3dmark 11 scores to compare?

 

i would take it quite easy OCing my Nvidia laptop card for some longer times.............i got strange artifacts after I OCed my go7900, the issues came after 4-6months. (dont also forget that go7900 have enormous over-clocking potential)

its not about the temp (i had normal temp all time)....its about you "stress" the GPU with more current then normal, (and sometimes more Volt (if you bios flashing)

anyway.....it ended that i had to replace the whole card........................
just a reminder

 

It can harm your gpu if you are unlucky.. we all know that OCing is not the best thing for your card, but personally I enjoy more OCing lately than playing games.. i had my voltage change and clocks on maximum stable on my asus G50vt for 2 and half years and no issues..

 

I just found out that the resolution and maybe intensity of your work affects maximum clock. When I played WoW with 768p it would never hang with 790/1060. But When I play it with 1080p through my TV it would hang occasionally and I had to lower the clock to 780/1060.

 

Well higher resolution obviously pushes the card more. So probably your temps are reaching to a point where it starts to throttle at that resolution. My guess anyways =/

 

My temp never exceed 65 playing WoW. No big deal though, I will rather take 2 or 3 lower FPS than unstablility

 

Thats interesting then. Well the downclock isn't huge at least.

 

What's the maximum T° in (Celcius) that the GPU never must exceed?

The mine is operating in 48/52° Idle, 79/85° Full Load (without OC.)

 

I believe max temperature for the GT 435m is around 105° Celsius.

My overclocked GT 420m sits around 49°-51° Idle and around 82° -84° Under Load.

 

8900 running 3dmark06 740/925mhz.
