How do I overclock an 8800m GTX!

Hi all.
I have a Clevo M570RU with an 8800m GTX.
The driver verison is 175.63.

I have tried useing ntune 6.02, rivatuner and atitool to overclock, but have not managed it!!

Is there somthing I am missing out (other than knowledge lol)

Thanks

 

I don't know.

 

have ntune autostart at startup an SAVE your overclocking benchmarks befoe doing this though.

 

Or you can change the bios of your card... which isn't recommended if you can't even get software overclock to work.

 

Ntune does not accept any changes I make. I will try again.
Looked into the vbios oc, not sure I want to push my luck with that sort of thing. I just know I will brick it lol

 

So far I have not found ANY software that will overclock my 8800. The newest version of NVidia system tools will downclock it from my bios OC, but then won't let me put it back up to what it was before (have to restart to get back). If you want to overclock the 8800 in this system: flash the vbios...

 

Urg, was affraid of that. I may just stick to icing the cpu from 2.5 to 2.8. Gives me a nice performance boost in mas effect

 

daverage,
Your 8800M GTX will NOT soft overclock. I spend almost two weeks slaving over finding a way to do a soft OC. Eventually, I settled on what many would claim to be a dangerous process of performing a vBIOS flash. I found that is was actually quite easy to do, and if you stick to the main way of flashing and don't deviate, there is never any reason for something to go wrong.

There are some workarounds with particular driver revisions that would allow a soft OC to work, but its not easy, I don't know the particular driver rev off hand. I'd recommend doing a hard OC to a good safe range of 1.05v @ 600/1500/950. Hard clocks are also a bit more stable than a soft OC, plus you can upgrade your vBIOS to the latest revision, which further increases stability and performance. Let me know if you need help with doing a vBIOS flash.

 

pm a user named markus.krainer; he OC'ed his AW m15x's 8800M gtx with fairly stable results.

EDIT: sorry, that's markus.k ainer, not krainer.

 

Alienware is running a slightly different version of the 8800M GTX. They do not clock the same as our M57RU's. Different BIOS's also. PM somebody who is running the same card as you and has some experience with overclocking.

 

There is nothing wrong with flashing vbios to oc the card. If you get a corrupt vbios you can just flash the default. I've flashed different vbios about 11 times and never had any problems.

 

I know, but I'm just saying if you don't have the tech skills to back it up, its best not to do it. My desktop card is bios OCed, but as I was researching it, alot of people did it wrong and was never able to change it back.

 

Tech skils are not the issue for me lol. It is a question of bottle!!

As it happens, I randomly stuck 175.75 drivers on to test and all of a sudden ntune 6.02 oc kicked in!! Which was a shock as I had set the settings and forgotten about it and was left with a most screwed up screen, But for now it is all working great.

I am looking at doing a vbios flash, though ill need some help hehe. I hear tht is the only way to oc both the gpu and cpu, flash te vbios and use setfsb.

 

No, you can only choose one, either cpu or gpu.

 

THought so.
Although at the moment it is stable with my t9300 at 2.8ghz and my gpu set to
525 / 825 / 1300

Not much but a boost. Read your thing on cpu vs gpu clocking and still can't decide which route to go lol.

 

The CPU can take an OC for longer, without any long term damage. With the GPU, the life can be cut down a little if you run an OC too high for too long and too hot.

It really depends on what your doing. I experience far better gameplay with a GPU OC. My render times in Vue 6 are cut down a lot with a CPU OC. So its really what you want to do with it.

 

Thats why I am considering using soft OC. With nTune I can set it to only overclock when a certain game starts.

 

Ya nTune has a lot of advantages on that side. Well best of luck to ya then!

 

Thanks for all your help!
On the one hand if I flash I can use any driver I want.
On the other it may shorten my laptops life expectancy... and that needs to be at least 2 years!!
Mind you I could flash to a faster rom, then use nTune to downclock the GPU for normal windows use and then let rip in games

 

Very true! If your wanting at least two years out of your system, I'd recommend the 600/1500/900 clock speeds. They are fast and easy on the system. I'd say go that route, using the latest vBIOS. The card will run at stock speeds when not under load anyways, and will only kick in that high clock speed when an application requests the driver to do so. If you want, I've got a vBIOS that will extend your battery life a good 25-30 minutes when under any load except when running a 3D app. With that and configuring the CPU and OS for better power settings, I've gotten just over 4 hours of light use under battery.

 

I will have a go at the bios you sent me, i don't use battery to be honest lol.
Is it to do with lowering the voltage by any chance?

 

Ya thats a large part of it. Running .7v vs .85v. Makes a big difference.

 

What emike posted was for the 2d and thrtle voltages. DO NOT set your extra to . or it will crash on every game leave the game at 1.05 with the oc.

 

Right well grabbed me nuts and did it!!

600 / 1500 / 950 and stable with my t9300 oc'd to 2.6 10365 3dmark

Massive thanks to emike09!! Thanks

 

well done daverage. nice scores.. pity i cant over clock my processor.!!

 

hey emike09 can you send me the vbios also?

 

What temps are you guys getting with both CPU/GPU OCed?

 

so now its possible to OC both the cpu&gpu?? is there a new bios or vbios that makes this possible?

 

I think there's a physical limitation of mobo for OC'ing both, so new bios/vbios won't help. I could be wrong tho.

 

well, I tried using the .7v and it wont get into windows with the v that low, gonna try .75 or lower the clocks even more.

 

THere is a limit to how much you can combine gpu and cpu overclocking.
If i push it to just 2.7ghz with the gpu overclocked i get directx rendering errors!!
It is a balancing act by the look of it.

I am running at around 60-70 deg on the gpu and 40 - 50 odd on the cpu

 

@brandon, are you talking about voltage? LOL i have 1.05V on mine.
@daverage, yea with GPU OC'ed, I can only boost 100mhz on my CPU.

 

ok lowering the clocks to 100/312/100 works for .7v

 

right now, I was working on getting the 2d graphics clocks and voltage as low as I can. For a cooler computer and a little longer battery life. I'll start working on the overclock settings next. I should be able to get a pretty decent score with overclocking the cpu and graphics card, I don't have to use set fsb to overclock the cpu.

 

what can I say besides "ENVY"?

 

Is this for 2D settings?And is there a difference in temps?

 

yes it is for 2d settings, its now at 100/200/100 and with max fans on gpu temps are at 36c. Flashing in my overclock settings now, next post should be with a 3dmark score. Constant restarts are keeping temps no higher than 38c

 

My 7950GTX still runs cooler by default

 

but can it do this?


ok heres the first 3dmark test, this is with no cpu overclock, next test will be with the cpu at 3.2 ghz.
This test is with the 177.39 drivers on windows xp with my cpu at 2.8 ghz not using setfsb.

 

No.
But my SLI 8800M GTX does better

 

so imagine what you could do if you overclocked them

 

ok here is the final result, this is with 177.39 driver, 3.2gzh cpu and 600/1500/950 gpu settings

 

I do imagine.
30fps average in 1920x1200, crysis all high

 

just did the devil may cry test, temps never went over 70c. Going to run a lost planet loop for a few min to see what temps get up to

 

Wow nice scores!!!

 

Great score and good job.I also need to underclock the cards.

 

Underclock? What sort of settings would you be using for that?

 

As bwxheon said in the previous page.Those settings at lower voltage for lower temps when it's not in need.

 

So am I understanding this correctly? You undervolt the lower clock levels on the gpu, which in-turn allows for OC of the gpu @ higher clocks and thus allows for CPU oc as well? Or is this you can OC the CPU a little bit and the GPU a little bit?

 

no you are mixed up about a few things. The lower voltage and lower clocks are for 2D mode allowing the laptop to run longer on battery and also run cooler while not gaming. People who do not have a xtreme cpu are only able to overclock by using setfsb, which overclocks the entire system. Since I have a xtreme cpu to overclock I simply go into the bios and increase the cpu multiplier. This allows me to overclock just the cpu and not the entire system. Which means I can overclock my cpu and my graphics card at the same time.
