overclocking 260m

I didn't know your finger was a precision thermometer.

 

With 1v, 600/1500/900 was not stable, had to go down to 580/865/1450 and it was stable. Temp reduced by 4-6c on GPU and ACPI. Max GPU temp after 10min with OCCT was 80 compared to ~84 with 1.05v and 600/1500/900. Ca 2-3% performance loss, but thats not much. Think I keep it this way.

Is it better to flash it to these clocks, or let Ntune auto change it to 580/865/1450 on startup?

 

If those are to be your long term primary clocks, flash it. 580/1450/865 is still pretty good for 1v.

 

I'm sorry if this is a noob question but what do you mean by "flash it"?

 

this is just updating the code of the bios instruction, so that it will see the new clocks for the gpu.

 

Sorry about bumping this thread, but I'm completely lost on overclocking, I was wondering if anyone could break it down or point me to a tutorial. I have RivaTuner right now and I'm not sure exactly where I'm supposed to go from there. Currently my NP8662 is running Windows 7 with the 186.03 drivers from Nvidia, am I supposed to get new ones to overclock with?

Thanks for any input

 

Download and install Nvidia system tools (Ntune 6.03) and open the Nvidia control panel. Under device settings you can increase the memory/core/shaders. Theres a limit how much you can overclock it without have to increase the voltage by flashing the bios. Increase the clocks a a little and test it with 3dmark06 and see it is stable. When it make artifacts, turn the overclock down a bit.

The core/shaders should be 1:2.5, atleast my 9800M GT, meaning when core is 500, shaders should be 1250.

 

Many thanks dude

 

No problem

 

Ah sorry about this but whenever I try to run the utility, it gives me a BSOD and the last message I see is nvoclk64.sys

Any ideas?

Edit: Ok I updated to 6.05 version and it works now

 

Remember to flash it when you find a stable OC. BTW I was wondering, is OC'ing a single card the same as SLi?

Cheers,

 

Yes, it is better to flash it to the stable clocks.

I have never OC`ed cards in SLI, but I guess it is simpler with one card. Just increase the clocks. Instead of flashing two cards, you have to flash one.

Im sure there are others who can give you a more precise answer, or you can just google it.

 

lol everyone is talking about flashing their cards with the new card settings but can someone actually post a vod mod file so we can use it.

Im surprised nobody has asked for it yet.

Oh and also is the command you type still... -5 -6 flash *card name* in the bios? If not wot do you type?

Many Thanks.

 

Okay, here's an upload with everything you need to put on your USB drive. The 260M BIOS is set to 610/1525/925 @ 1.05v.

The command is:

nvflash -4 -5 -6 260M.rom, press 'y' twice and you're done.

 

Uh... does anyone know how to get ATItool to even work... I used it religiously on my old desktop.. but when I try to use/install it on my 8662 I get the error "Windows Vista only uses digitally signed drivers... " yadayadayada. Then when I run it.... it doesn't detect my GPU.
I have the latest nvidia drivers installed.

(260m)

 

I get those same messages, but I run it anyway. It doesn't detect my card's clocks, but the artifact scan still works and heats up my card.

 

What does "to flash a card" mean? What does it do and how do you do it?
Thanks

 

To "flash a card" basically means to change the profile of the cards setting....

So for example the stock speed of the 260m gtx is 500/800/1250

When you "flash it" with a new bios so to speak you can change the core/memory/shader to whatever you like (within reasen)

*Warning* dont get carried away though because flash it TOO HIGH then the laptop either:
A. refuses to boot up
B. **** your laptop!

But you can make a moderate overclock within a region....remember though...larger the overclock then more voltage the card needs to operate properly. Just check temps and you'll be fine.

Kevin jack...thanks bud for the volt mod...dont suppose you have the oringal mod for the 260m gtx in case anythink goes horribly wrong and need to flash it back to oringal!!! Would be greatly apprciated!!

 

You should save the original BIOS before you flash your card, Sailor4UK.

Settings the overclock too high causes your GPU to display artifacts, but in most cases it will still boot up.

 

ooops spoke to soon.

I see the oringal is already zipped in their!! nice

Havin a problem though with Nibitor 5.1 to recognise the 260mgtx though. Thats the lastest version of nibitor aswell!?!

 

I havnt flashed it yet

So No mistake.

 

Switch the device ID to 9800M GTX and rescan the BIOS in the adv. info tab. Make sure you change it back to the original unknown ID before you save.

 

yes rescaned and the integrity turned from green to yellow???

1. Yes the id was 0618: (unsupported)

2. then change to 9800m gtx (theirs two in their so hopefully dont matter)

3. then change the id from 9800 gtx back to.... 0618: (unsupported)

4. then save? correct

thanks

 

is it feasible to undervolt the pc and oc the gpu moderately to end up with more or the same battery life? if not ill just stick to undervolting...unless i figure out how to make it overclock only in games..and if its not a hassle.

 

Unless you are willing to sacrifice a chunk of performance, you cannot undervolt the GPU's highest level as it needs 1v to operate properly at factory clocks. However, you can undervolt and overclock the lower levels just fine.

 

shouldnt really effect the battery life as the computer automatically undervolts and overclocks the voltage when the laptop is in 3D use and 2d use.

 

@ sailor did not know that.
I meant to just undervolt the cpu
I will research how to do all this once i get the laptop on the 17th

 

All done in four easy steps. Yes, that is correct. After step two, you do all your edits, then do step three and then step four.

There are two versions of the 9800M GTX ID: 0608 and 0617. 0617 supports SLi while the former doesn't. It doesn't matter which one you pick though.

 

awsome thx for the advice!!

 

Sorry, I misunderstood your question. You used "pc" to describe the CPU, so that threw me off.

Yes, you may undervolt the CPU and mildly overclock the GPU.

 

yaay battery life and performance when i need it/plugged in

 

@ drake333

I really dont know how much you will gain in battery life for undervolting the cpu... not much id reckon and the cpu needs a certain level of voltage to run at the higher speed properly.

If your getting the sager then it has a silent mode option which (when pressed) slows the processor RIGHT down so it consumes batery life.

 

lol...so it *doesnt* consume much battery life

 

as long as it can handle these i wont need to overclock


doin some 3d rendering and gaming
Solidworks
Autodesk Maya

Crysis
sims3 < should be able to
Tom clancy hawx
Prince Of persia 4 omg oo
age of empires 3
empire earth 3
sins of a solar empire
hellgate london
civ 4

 

wot do you mean by "handle"?

You will be able to run most of those games with maximum details except crysis which is a system hog.

 

well by handle i mean no screen skipping which happens when fps goes down. I am really hoping the sager can do some 3d rendering..i did not want a desk top or a workstation graph card. Sooo looking forward to prince of persia and hawx.

 

It can do just as much 3D rendering as an equivalent desktop card would - which means enough for most people Same goes for games. Basically, GTX 260M isn't all that much behind a desktop 8800GT in performance, and a 8800GT can still do all modern games just fine.

 

Wow...
Currently on nvidia whql 86.03 drivers as i cannot get powermizer to work on the 190.38 drivers from laptopvideo2go...bummer.

However at 1.05 volts and clocks @ 610/1525/925 is stable but the temps reach 102c playing Empires total war lol!!
ATI tools only goes as far as 82c!

Think i may have to get rid of the volt mod unless its the drivers that causing the temp surge.

 

Games like these tend to burn the GPU alot. I played Anno 1404, and my card went up to 90c after a few hours, and I thought only OCCT was capable of making my card go over 90c.

 

Update:
Found out the problem!

Nvidia whql 86.03 was sending empires total war temps to 102c!!
While nvidia desktop modified drivers (190.38) i love these drivers....
were running the game at a cool 82c!! and with better framerates!

The 190.38 drivers do downclock to 2D clocks when the gpu is not in use (which i like!) cos i noticed when i quit empires total war they were running at 200core/100mem

but when watching a blueray movie (windvd or tmt3) and quiting the movie..the clocks still stay at 3D 625/925 which i really dont like.

I wonder if i can get the gpu to revert back to 2D clocks once the blueray movie has finished.....

 

anyone? lol

 

720 core 1095 memory 1755 shader

my higher overclock on my GPU....

I need to fix the clocks but since i can't push my memory much further i haven't bothered

 

you have got those clocks on a 260m?
I sersiosly dont believe you!

And if you have done so then you must get some sersious artifacts when gaming!

 

nope i got 6200 on vantage

i have MXM 3.0 card .... I can actually OC futher if i kept the ratio

 

just need to find a bloody way to get back to 2D clocks from watching a blueray movies.

This is soooooo annoying

 

Revert back to 186.03 WHQL.

 

with 102c temps when playing games....nar

im thinking off changing the 3D clocks to 200/100 and obviously leave the ultra clocks alone.

 

How are you getting 102*C?

In NiBiTor, I always lower the downclock threshold of my GTX 280M from 108*C to 95*C to match my CPU's downclock threshold. You should do so as well as the M860TU is more likely to surpass 90*C than the M570TU.

 

hehehe found a solution....IM SO CLEVER ITS ALMOST SCARES ME SOMETIMES!!

Changed the clocks using Nibitor...

So oringal clocks were:

2D: 200/400/100
THROTTLE: 275/550/301
3D: 383/767/301
EXTRA: 620/1500/925

Now the problem when watching a BlueRay movie is that after finished watching the film the clocks never went back to their oringal 2D clocks (this only happened on the modified 90.36 drivers i am using now) but stayed on the ULTRA clocks on AC power or stayed on the 3D clocks while on battery.

So.........

I changed the clocks through Nibitor as follows...

2D: 200/400/100
THROTTLE: 200/400/100
3D: 200/400/100
ULTRA: 620/1500/925

So now i NEVER waist battery life when watching a blueray movie as the clocks stay in 3D mode...and when plugged into a AC power i can still use the ULTRA mode for gaming!!

And whats more is that their is a silent mode on my sager laptop which brings the CPU and GPU to a minimum clock! So watching a blueray movie on AC power brings it from ULTRA to 3D!

And it works Beautifully!! Yea go me!!

Next....im going to see how low i can get the voltage on the 2D setting to save more power!! woop!

 

Whatever floats your boat.
