[m15x] Finally I´m able to OC the 8800 GTX

@Tech17

I just saw, you running your m15x with Windows XP ... there we have anyway a small different!

And to your battery issue ... first of all, I´m not playing on battery mode
This is normal, ALL laptops I had and I know do the same ...
The only thing which can maybe work is, you disable with nibitor in the bios the first 3 Levels .. but than is your videocard running ALWAYS with FULL power!

edit:

Sorry, forget about it ... it´s not working, I just tried it ...

but one more thing ... maybe you can spped up the gpu/memory in the level 2 ... put then you have again your m15x running always on full power

 

Thanks, tried that and no, just reverts back the second you pull power...

while on battery, you can set riva tuner, but it fails the test below factory settings, so it will not allow you to apply.

I've even gone as far as setting like +1 to core/mem and selecting "use at startup".
reboot on battery power and guess what? the setting are ignored. Still pulling 5.5k 3dmark06 while on battery, but thats roughly 1/2 power

you are correct, most notebook (by default) do some form of dowclocking when on battery to save battery life. but, they also have the option to shut it off...

in the case of the m15x, it should not downclock the GPU "at all" when on battery (or at least have the option to) or tell me what is the point of BinaryGFX in this system...

If your notebook does not perform on battery, its not a notebook sorry. it has more similarities with a desktop at that point...
and please dont try to tell me the 15'' m15x is a "so called" desktop replacement... people got away with that excuse for years on 17" notebooks, but i'm not buying it on a 15"...

 

the 8800M still needs a lots of more power as the X3100 graphic chip ... that´s one point of BinaryGFX.
And the X3100 Chip is much cooler as the 8800M ... that means also less fan noise!

 

Even though the 8800 is at half speed you're still running about 10x faster than the Intel video card can go. The internal card gets a 3dMark06 score of around 575 ... and that's plugged in!

 

hmmm ... I don´t understund what you try to tell me

Even if the geforce is running with the same power on battery as pluged ... you have maybe 30 minutes to play

edit:

634 ... lol

 

lol, i only got 493 with in Intel GPU plugged in.

exactly! and thats fine for some. and if you need more then 30min, you would switch to the Intel GPU...

I would understand the downclocking if there was no BinaryGFX. but the whole point to BinaryGFX is to own a powerful, but battery hog notebook that can be adjusted to conserve battery life.

If battery life is any concern, whouldn't you change to the intel GPU? or are you saying that while on battery you sill want "some" power, but not all? i cant think of a practical time that would be helpful...

I think if powermizer worked the world would just be a better place for all...

 

Hmm ... no, I´m happy with how it is ... if I´m playing games, I´m always at home or on a LAN party or by an friend ... so I never play with battery ... and when I´m working with the m15x I switch to the Intel chip and be happy about 6 hours batterylife ^^

sorry, I can´t say anything to this, I mean, I understand what you mean .. but I even think, that the battery power at all is not able to handle the power of a 8800M when it´s fully working ...

Anyway, that´s not an fault from AW or somthing ... because I really don´t know, if there is any Laptop with a HighSpec videocard and which you can play on battery ...

 

Don’t get me wrong. The reason the 8800m is downclocked even when the system has BinaryGFX (one step before hybrid SLI) is because running this thing full power on battery would be considered impractical… From my battery benchmarks I estimate :45 min battery with CPU and GPU running full force on this “tiny” 6 cell battery.

But, if you really feel that way you should honestly consider spending the money on a desktop… you can get a lot more power for this price out of a desktop, if you have to be plugged in all the time the only advantage of a notebook is portability. But it’s basically a desktop with a intergraded LCD… kind of like the LCD screens you’ve seen on the PS1, 2, and now 3 (for example).

To be DEAD honest the m15x does MORE then enough then “I” need on battery as it is with the games I’m playing, even with the downclocking, right now. I’m just worried about the future. Even with present times you’re not playing games like Crysis with this guy on battery…

But sorry, facts are facts. This system includes an intergraded Intel GPU so you can use this system for extended periods on battery. There is absolutely 0 reason for GPU downclocking on the Nvidia card. With the common public view of high performance laptops on battery (basically using them as desktop) I predict the problem will only get worse. With hybrid SLI right around the corner I suspect well start seeing extremely high performance notebook PCs that default to the intergraded Intel GPU when on battery, no matter what you do… and they can dynamically change to the low performance GPU whenever they want. Whats next? Defaulting to a Intel GPU even when plugged in?! common, they already downclock the m15x’s CPU even when on battery “no matter what you do” *cant set it to run 100% full time*

 

in another thread someone already explained why graphic cards in notebook GENERALLY downclock when the notebook isn't plugged in. If I remember correctly the reason was that the battery can't provide the required voltages.

Any chance of a step by step guide on how to do this coming up?

 

I don't buy that at all. The voltages need to be constantly maintained for the CPU and chipset to function at all. I think the downclocking on battery issue is due to practicality, as was suggested above.

 

SORRY guys ... give me few day´s ... I have also a job to do, to get money, you know ...

but I´ll share my "knowlledge" with you, don´t worry ...

 

Markus, you're a star. This news is very good indeed, i wonder if the same theory applied to the m17x (assuming it works as good as the 1730) would produce the same if not better results...

OB

 

i was able to figure it out with the help of GROOVE75's volt changing walkthru...
after following his walk thru to change voltages i flashed to a lower voltage and thought to myself i should see if i can change the clock speeds too, and it worked!! then after changing the clock speeds in the cards bios, i was then able to alter them further with riva tuner v2.09 (i only tried changing the top tier performance clocks). so im thinking the flash removed some kind of protection from driver level overclocking too woohoo!!
i hope this is useful to everyone and if you have questions feel free to PM me ill try to answer them as quick as i can

 

For guys who didn´t see the guide

Overclock Guide

 

Markus, just out of curiosity, how on earth are you keeping your 8800 temps so low?? I have to undervolt to keep a decent temp; I can't imagine overclocking this card... I'd go nuclear! Are you using a cooler or have your laptop set up in a tundra base tent perhaps?
