485m overclocking results?

There is an overvolted bios (485M, 470M, 460M) by Makve (NiBiTor Author). It's on the X7200 owner's lounge. It only goes to overvolt mode when on load, idle voltage is still the same.

 

same one posted on the first post? the 1.03v?

If you overclock the 485M, does it still underclock when using 2D applications automatically?

That's one of the most attractive things for me about NVIDIA cards, IMHO....they rather aggressively downclock so that you can save battery life.

Mr. Mysterious

 

yup, it's already been posted on the 1st page

yup.. in my experience it downclocked itself quite well.. the overclocking only seemed to take effect when it was running at full 1V

 

i can confirm that as well. there are three different "P-states" that control the GPU: low idle / active idle / 3D or full power. overclocking just affects the 3D P-state, the other two just stay the way they are. its really quite handy!

 

actually using invidia inspector, i think you can adjust the p(0), p(1), and p(2) states

 

true that, i was just referring to the actual "standard" overclocking. the other two P-states would of course be interesting for downclocks ^^

 

Hey guys, any of you find that the (user specific question) Sager NP-8150 with the 485m seems to run furmark burn-in tests fine at stock clocks, but as soon as you overclock looking to get some more frames out of the card and raise the core freq say 15-30mhz it will run the burn in test for about 5 minutes and the computer will actually shut off and reset entirely???

Is this a sensor/safeguard function built into the computer? maybe a temp sensor that shuts the computer off rather than actual GPU instability?

I have my doubts because under furmark burn in at stock clocks the gpu might reach 90-91 degrees, overclocking the core 50-70Mhz might get it up to 93-94, runs fine for a few minutes and then the computer just shuts off and reboots.

I'm scared of harming my GPU or something. I'm backing off overclocking for now. any comments/tips are welcome.

On a side note, any overclock will grant a few more frames playing a game, for example in Crysis 2 i achieved raising frames from about 35 to 39 avg (1080p, highest settings possible), but the game will crash after about 15-30 mins of play like someone posted before. It's fine and suddenly you get some weird artifacting and crash.

Waiting on NiBiTor support for the 485m to overvolt and get a decent (STABLE) overclock.

 

It's called a benchmark, and one card or another is notorious for scoring higher despite real world gaming performance. No doubt the 6970 is a fair match to the 485m but it doesn't "OWN" the 485m by any means.

 

Hi,

I am new to the concept of over clocking graphics cards. I was wondering, is it safe to do? Should i be concerned about overheating my laptop and in the long run shortening the life of my hardware?

 

That's it with overclocking. Just monitor your temperatures and as long as the GPU remains <80C-85C you should be good. In many cases though even if your GPU is running cool, it may not have enough voltage to overclock much, so don't be surprised if you can't OC by a whole lot.

 

That was actually a really good quick explanation. I was wondering though, what gives the GPU more voltage? I know voltage is an electrical pressure difference across one object that produces resistance. But, do you get a better delta V through a more powerful CPU or power supply?

 

No, you need software to adjust the voltage, if the voltage isn't locked for pushing it higher. I haven't even tried yet, and my machine is out for repair at the moment, so can't try. Didn't try mainly because my system can max everything so far without need for overclock. Probably be that way for at least another 6-9 months. Battlefield 3 may push its limits though.

 

the best is to use nibitor to change the VBios since the v is normaly locked on Laptops

 

Is everyone's 485M locked @ 1.0v under load & .85v @ idle?

I overclock my desktop 580's, but I try to "undervolt" them to the lowest voltage, while getting the highest O.C.

I don't feel comfortable overclocking a notebook GPU,...BUT, if I can achieve a 10-15% increase in performance on or below the 1 voltage marker....I "might" give it a try.

Also, I don't feel comfortable seeing GPU temps above 80*c. I recommend shooting for the coolest temps possible.

 

Here my 485 SLi results.

Wow, almosy 7k in 3dmark 11, congrats) You've got awesome temps on both cpu and gpu's, what kind of cooling do u use? i bet it's somewhere outdoors) also, is it your stable gaming OC of the system ot just for benching?

 

hi,
for benching i run the fans at max
my room temp was 24c.
the system is gamestable but for gaming i use the standart settings.

 

updated

i'll try to keep up with this, even though i no longer have the machine or a 485m. (unless someone else wants to take over it )

 

yehaa my two 485 is finaly arriving to morro bin stuck in customs for a month
started preping via lapping one of the GPU coolers to morro the other one is going to get lapped only down side is dont have any IC D at home and its a B to get in Poland so i have to go with AS 5 but thats ok to
Have taken some pics will post them when im done with the other cooler and the cpu cooler and the shims

 

Hi guys my pics and benching will be delayed a little ran out of sand paper for the lapping of the GPU coolers since i calculated that i could use the ones i had but i got new ones with the cards with a dif GPU stamping in them so the old ones wont due since the stamping is placed in a dif place so it can interfere with the cooling i think dont kill me if im wrong havent done proper mezurements but just looking at them there is a small dif so getting new paper to morro and trust me they arent straight any where alot sanding to do

 

I run SLI stable at 730/1660/1460. My Vantage score at these speeds with my i7-960 @ 3.6ghz hangs around 30100.

I normally ease back to 680/1600/1560 for day-to-day gaming use. There's no game I've played so far that slows down, even at the 485m's stock speeds in SLI.

First run after installation pics and Oc max on standard Vbios and Oc max on Bumpt VBios coming later have to try these bbys out in some real gaming

 

Hey, nice scores) Can you also post 3dmark11 ran with OC and temps using HWinfo? Is your CPU and GPU at stock voltage? And did u use the latest Nvidia drivers?

 

hit 33000 to night will up load later

 

Here i some pics from when i resived the GPU's and was lapping the GPU Heat zinc's

here is the Heat zinc Like it comes before i remove any thing

By torment78 at 2011-06-17
the thermal pads are very fradgile so be careful when removed put them on a clean plastic film and dont remove the green plastic put so its facing up
the preaplied Paste you need razor blades for and alcohol to clean of dont scrape to hard so you scratches becouse they are hard to get out

How i did it

Spoiler

Started with 240 grit and just do the movment like when you lap a CPU up and down in 40 reps den turn 80degree do 40 more untill almost flat then go with 320 grit just do the same but this time untill its compleatly flat then go for 400grit rotate after 40 then when you see there only markings from the 400 paper and its still flat keep on going to a higher grit count you be ok to stop at about 1000 or 1500 grit then you just get your polish paste and a cloth and start going at it when done clean with alcohol to make shore that no paste resedue or finger prints left on the heat zinc bada bing your done

AND THIS IS THE MOST IMPORTANT THING OF ALL

You (or the beer) posted it in no more than 4 threads?

Nice work. So much copper in that laptop

 

It was me that posted but its becouse some of the guys that i think like this kind of stuff are spreed over multiple thread's
there will be a big Vantage results post later may not happen to day do

 

hahaha, loved that post, especially the beer! keep it up

cheers

PS: just insane how much TDP laptops can handle these days....when im looking at those dual gtx 485m cant help but imagine the whole thing catching on fire when stressing it out!

I save the screen so it would safe now i cant find it will do a new run and take screen later

All overclocking was done with Setfsb for the CPU
and EVGA Precision 2.0.2 for the GPU's
NiBiTor was used for modding the VBios thanks to Mavke @ MVKtech.net
for hooking me up with ver 6.03
hope all you guys like the post
more will be done for Vantage non physx and 3dmark11 and Pcmark 7

 

sorry this is kindof late, but does anyone have a pre-modified vbios with the 1.03v. because the links in this thread are all for the standard bios, and i am unable to use nibitor to change the voltage. any help would be great, thanks.

 

Nibitor verson 6.03 is out and it support the 485M GTX.

EDIT: Weird. I just downloaded it, but I cant change anything. When I open the bios, everything is greyed out. Bug?

 

lol been looking for this and was wondering when it would come out thanks a bunch. + rep

 

you have to look under the tools section and then fermi voltage.

 

Guys... looking to OC my 485M too.
I would like to kno what numbers (Core, Memory, Shader) would be safe/,manageable? I was thinking at 650/1700/1300.
Also, what would be the best/easiest software to do this?
Tried with Nvidia Inspector but the Core Clocks seem to be greyed out... can't change them

 

these clocks should be fine but mem is enuff with 1600
but use theis soft insted its better
File name: evgaprecision.zip File size: 5.85 MB

thats what im using and its perfect

Are you using the modded Vbios or org ?

 

Thank you for the promp reply.
Already downloaded EVGA Precision and it's a great sofware.
Have applied 650/1700/1300... are you saying 1600 for memory is enoguh? No big difference between 1600&1700?
I'm using the original Vbios... what would be the benefit of the moded one? Higher OC because of higher voltage? Wouldn't want to mess with voltages though...

 

in this file you have the bios plus some tools and other software File name: evgaprecision.zip File size: 5.85 MB
in this one is the bios and boot usb tools File name: all files needed.rar File size: 5.74 MB

 

the 1600 or 1700 dont make a dif in performance if you are not going for the max then you have to play around to get the highest mem with out lowering the gpu

 

And for Core what would you advise? 650? 700?
thanks

 

what laptop are you using first of all and hows the temps at stock lets say 30 min of furmark
and also do a couple of runs with Vantage on performance and see what top temps you get since Vantage gives the best simulation of gaming when it comes to heat and usage of the gpu for being a benchmark .
if you think the temps are low enuff then bump them maybe to 600 do the same this will also test the stability of the Overclock if they are still adequit bump the Oc a bit higher do it over again .when you found a limit of what you are confident that wont fry your gpu then start bumping the mems same way if you get artifacts or the nv driver start stops responding you have bump them to much .
this nv driver have stoped working is one of the indecator that you need to bump the V in the bios

 

played about 2hours of Battlefield 3 @ 650/1300/1600 and everything was ok. No problems, no artifacts etc. temps arround 78-81C on a Sager NP8150.
Looks good...

 

that sounds a bit high mine only hits max around 71 to 74 @ same settings
you got a laptop cooler or maybe your ambient is high
it no danger to your card i was just a bit chocked since i have run furmark on burn mode over 2 houres @680/1360/1600 and not hit over 76c

 

what room temp u have??

 

it goes up and down 20c to 23c

 

have a look at my Oc posts from earlier on this thread


it will give you some ide about temps @ certen clocks

 

Well... I already us a Zalman NC-3000U cooler. It's not that great but still.

On stock it is also arround 74-76C... but the max i saw was 86C which I consider still ok.
The problem is that playing BF3 brings 2 cores of my CPU to arround 93-95C somtimes.

 

ok i would recomend to change the TIM to ic diamond thats what i use on both gpus and cpu and if you all reddy havent open up your bby and clean the cooling fins

by the way im using NZXT cryo lx but it only give me about 1 to 3c dif wile lifting it up on top of the cooler gives me 1 to 2c allready there so its mostly for my peace of mind that ive had tried every thing

 

TIM is already IC. I bought it from XoticPC and opted for IC7 paste too... that was back in may...should be still good.
