Got my 9600M GT running at 60 degrees on load!

Hello all, as i've posted before, i had serious problems at first with my 9600M GT in my Acer, 105 degrees at first, then managed to get it down to 95, then 90.

now i'm running at 60 degrees max on load! 39 degrees idle.

im VERY pleased with it, what a did was....

Took a small fan out of another old laptop which was lying about, took a usb lead, cut the end off, got the two wires, connected them to the fan wires, to check to see if the fan would work, it did....

so next, i thought hmm, this fan looks small enough to go on the heatshield on the back of the 9600M GT, and guess what, it sits on it perfectly! i've got the back case open of the laptop, this doesn't bother me because it doesn't move from where it is, HDMI via my LCD TV.

so there we go, 60 degrees max, huge drop from 90! and should add a year or so onto the life of the card,

one thing, it can drop further, but the actual fan inside my laptop stops when it's gets to a certain temp, so then it's get a bit warmer, then the internal fan starts again, anyway i can get this to kick in at a lower temp?

Thanks.

wow nice well hopefully you can keep the dust out of it though... perhaps you could do a Little bit o overclocking with temps relativly low like that eh? IMagine the look of your lcd with even higher settings on Crysis

 

nice idea.. any pictures??

 

Yea i'll get some pics up soon.

Yeah i might oc a bit, i've done it at 600mhz on the core, 100mhz over default. i won't touch memory though, due to no temp sensor on it.

i've undervolted though, so that 100mhz overclock, would that be the same perfomance, as if i was to go back to standard voltage on the GPU?

 

It is the same performance as long as the core is stable (ie. 600MHz=600MHz; 600MHz>500MHz).

 

So basically, i'm undervolted to 0.89v right now, and overclock to 660MHz, i start to see artifacts.

If i go back to standard voltages, and overclock to 660MHz again, would i still get artifacts?

 

Probably, artifacts usually mean your gpu is tapped out .

Try it on standard voltages anyway in case it wasnt receiving enough power. Always keep track of your temperature.

 

That depends on what is causing the artifacts. It could be the ROPs, Shaders or the Memory. Typically when you give things more voltage they can run at a higher frequency, but there are exceptions to this rule. You will certainly have a better chance at hitting 660Mhz with the standard voltage versus the undervolted, voltage. That seems redundant...

 

Actually, with this super crazy LOW temperature of your GPU.
You can OC about 25% on Core, 10% on Memory and 25% on Shader(2.5x of Core).
DDR3 Memory have lower temperature if not mistaken. Basically, slightly OCing on Memory will not have any problem. More than 25% of Memory OCing is quite dangerous.

Glad you have such a LOW temperature, envious indeed.

 

Wow, both impressive and interesting. I look forward to pics!

 

I achieved same temps on load (albeit with my cooler to help things out) by undervolting the card.

As far as overclocking goes ... I wouldn't recommend going past 600 Mhz on the 0.89v.
I think you can go slightly higher (625 Mhz), but beyond that, you'd need to likely increase the voltage.
It does vary from card to card, but I don't see a reason on going over 600Mhz on 0.89v since you get decent overclock with lower temps and won't risk bricking your card in the long run.

 

Thanks for the replies guys, just going to add pics.

 

Pics Added.

 

LOL. I think you should cover your Product Code there. I don't know if there is any danger showing the License/Product Code in public.
So, you add a FAN on the heatsink of the GPU?
But it seems it needs to open up the bottom casing everytime right?

 

lol

Yea that's all i did, as i explained in my first post.... the back is open yes, but it's elevated, and sitting in a TV unit underneath my 52" LCD TV, plugged in via HDMI, so it can't be seen, and looks quite nice

 

Nice idea. The cooler the GPU the higher the performance anyways as heat kills performance, I can imagine your GPU will push the frames as well as a mildly OCed worse cooled 9600M GT, would be a beast OCed! + rep

 

how did you undervolt? are there instructions posted online somewhere?

 

Yea i can't remember where i found them though, you bascially need to edit you're GPU BIOS, and reflash you're GPU.

You will need a USB Flash drive.
NiBiTor and NVFlash.

NiBiTor, open it, click on Tools> Read BIOS> Select Device.

Select you're GPU.

Then you click Tools> Read BIOS> Read into NiBiTor.

This will load you're GPU BIOS into NiBiTor ready for you to edit.

Before doing anything though, click File> Save BIOS, save it as STOCK.rom or something, so if anything goes wrong, you can re-flash.

Next, click on the Voltages tab, you will see 4 drop down boxes, the one you will be focusing on is the "Extra" drop down box, this is the voltage you will need to change.

I'm currently running mine at 0.89v which is the lowest i can go...

select one, and then click File> Save BIOS, save it as NEW.rom or something similar...

next, you will need to create a bootable usb flash drive...

Once done, you will then need to place the NVFlash files onto the usb drive, also, you're NEW.rom file, and STOCK.rom.

restart you're computer, once the command prompt has loaded type:

nvflash NEW.rom -6

then it will ask you to type "Y" a couple of times, do that, once it's all done, restart you're computer, and then go testing!

If you need to go back to default. restart,

type:

nvflash STOCK.rom -6

Happy undervolting!

P.S there is many other things you can do with NiBiTor, like flash you're card to different clocks, hardware overclocking, so you don't have to do with software, once flashed with a higher clockrate, it's permanently overclocked until you flash again with different clocks.

 

Ok i've just gone back to default voltages, 1.05v.

succesfully overclocked to 700MHz, (default 500mhz) and tried a few games, running perfectly, no artifacts and maxing at 80, on some games not even going past 73 degrees! before, undervolted, i coulnd't get 650Mhz without crashing and artifacts, i've got a huge increase in performance now too!

 

Time to get a new CPU and ur laptop will rock!

 

wow 700mhz with that that card. I thought only 55nm 9650M GT and GT130M GT were to reach such high core speeds without a vcore mod. Congrats. You ought to push your memory at least a little. 950 would really increase speed alot.

 

Interesting and nice temps but not very practical ??? I mean you're obliged to keep the lap open, aren't you ?

 

Yeah but like i've stated, the laptop sits in my TV unit underneath my TV, plugged in via HDMI, it never gets moved... so it's all good

 

awesome. I think I will give this a try tonight and hope I don't mess anything up!

 

Yes when I had my 9600m GT the GDDR3 version I was able to get 745/950/1585 and what a preformance gain.. best of luck with this, everything looks good and stable..

 

Awsome mod. Rep'd.

 

My 9800M GTX is heating now max to 60C after the last driver update...

 

Very nice mod, congrats mate

 

That's a cool little mod for anyone who keeps their laptop in the same place for long periods of time

Have some rep for your troubles

Only extreme heat will kill performance. You wont see a performance increase or decrease as long as its <110C I think.

 

**mutters to self about stupid ddr2 9600m gt in hustheman's hp**

but seriously man thats awesome, i have done so much to get my temps as low as possible and i hit 65 running furmark, i would say in total it has taken my about 18 hours of tweaking and making things to optimize my hp's cooling

 

"awesome" is so relative.

if this worked with THE FRACKIN' CASE STILL ON THE COMPUTER...then it'd be worth talking about.

 

Thanks for the positive replies guys...

ajreynol calm down.... it's not the whole case, the back cover which is removed, is about half the size of the back of the laptop, if i spread my hand out over the removed case, i can cover the area. it's not that bad, and it's sitting underneath my TV unit, so it's unseen anyway.... i personally think it's a considerable gain in what i have achieved.

 

no wonder it ran so hot there was no heatsink
on the 8930g`s 9600m they added a heatsink for the gpu and the ram

 

The 9600M GT was not the original GPU in the 6930G, it had the 9300M GS, i bought the 9600M GT which came out of a MSI laptop from a member of this forum. it does have a heatsink.

 

A serious modder.


+ rep to you dude, now get a nice cpu in there.

I got the 6935G and pushed my 9600mGT to about 630 on core and 900 ish on memory, i'm feeling brave now and will push it some more tonight

 

Thanks

Nice OC, be careful on memory though, it doesn't have a temp sensor, i never oc my memory, well i have, once, but the improvement of FPS was miniscule...

So i just concentrate on the core, i got 700MHz stable at 80 degrees max, standard 1.05v. but i still think thats a bit high for my liking, 200Mz more than default, so i've kept it undervolted at 0.89v Oc'd to 640Mz on core. which is plenty i'm getting 10fps like that, and temps are not going over 63 degrees.

I will be upgrading to a X9100 next, or possibly T9600, depends what i can get cheaper.

 

hey guys.you know 8600 m gs is known as a overheating gpu

500 mhz 1000 mhz 400 mhz stock speeds.

pushed it until 670 1330 and 427 mhz.

now it doesnt pass 87C

if i apply a new termal paste i am sure it will decreas more.

what i figured out is that in call of duty 4 if you get a constant fps like 100 everytime your gpu heat will be low and you will able to overclock it more without artifacts.

but if you overclock it and still if the fps drops to 50 40 from 100 fps during the came you will get more heat and less overclocking tolarence.

 

How come you can get 100FPS?
I thought 60FPS is the maximal for current laptops.

 

i have a 9600m gt dedicated 512mb as well, and i run it overloaded at 75°C
could such a temperature harm the notebook?
