P-7805u GPU Overclocking Guide for Newbies

I've noticed a lot of new people coming to the forum in search of answers to various questions so I thought, being a newbie myself, to put up this guide for all the other newbies to this wonderful site. First of all, I take no credit for this guide, as I have just copied it from several posts made by SemiGamer. I hope you don't mind SemiGamer, but I found your posts very useful and felt that others would also.

P-7805u GPU Overclocking Guide

1. Download and install the drivers that work best for your system:

Nvidia - http://www.nvidia.com/Download/index.aspx?lang=en-us
or
Dox's - http://www.laptopvideo2go.com/forum/index.php?showforum=122

(if you need help installing these please see The Defininitive nVidia Driver Upgrade Guide here http://forum.notebookreview.com/showthread.php?t=265740)

2. Download and Install NVIDIA System Tools with ESA Support (the newest version is 6.03 however according to SemiGamer's post the 6.02 version was referenced, i don't know if it makes a difference) (Also when installing it's easier to allow the install to create the desktop shortcuts for you)

6.02 http://www.nvidia.com/object/nvidia_system_tools_6.02.html

6.03 http://www.nvidia.com/object/nvidia_system_tools_6.03.html

3. Double click on the Performance shortcut

4. On the left side, click the + sign next to "Performance"

5. You'll get three options, . Use the following settings:

Core Clock 600 MHz to 710 MHz

Memory Clock 799 Mhz to 950 Mhz

Shader Clock 1500 Mhz to 1750 Mhz

6. Click Save

7. Click Apply

8. Enjoy

According to skysky123 the GPU temp was around 68c

I hope this helps and if anyone has anything further to add, it would be greatly appreciated.

 

I don't understand, DL Dox's driver, and Forceware? Are they not both Video Drivers?

 

Thanks for the catch flynnaz, I made the appropriate edit. Maybe I should have waited to write this during my 2 toddlers nap time. lol

 

lol, I thought that's what you meant

 

I noticed something weird, maybe its just me when I downloaded the NVIDIA System Tools with ESA Support 6.03 the file showed up as 6.02, I double checked it too. I will look tonight to see if the program itself shows the right version.

 

Is there a way that we can modify the bios on these 9800m gts's? I wanted to play with the voltage a little (under/slight over) and you can't do that in the ntune software.

I have a p-7811 if that matters.

 

Doesn't work for me... Trying to change the clocks at all just gives me a "The changes made were invalid and will not be applied" message.

Ok, seems this doesnt work unless the laptop is plugged in.. Interesting.

 

Nibitor may be able to do it, I haven't been able to find out definatively if it supports the GPU or not, though frequently you can just use the settings for a similar device (9800m GT which is definately supported in new versions) and then change the device ID for flashing.

 

Something you guys might want to try is using the ORIGINAL drivers. I have had NO issues at all with the ORIGINAL shipping drivers. I have had some kind of issue with every other "modded" driver. Just my .02.

 

Yes - playing with the volts will save you massive trouble with a 7811 and gaming.

I have de-volted mine and overclocked my 9800 and had excellent results so far.

/Bump this thread =)

 

Glad to be of help Sega.
Note: I'd put "Install the drivers that work best for your system.

As part one, because the 181.20 aren't the best for everyones system, though if its for someone thats never updated their drivers or have never tried out others than the ones that came stock, 181.20 DOX is a good place to start for gaming. And the lastest official Nvidia might be better if they don't plan on gaming. But since this is an overclock thread. Chances are gamers are only going to view this

 

Did you use NiBitor? And did you have to do anything funky to get it to work right? I'm hesitant to try something that extreme on a laptop, even though its never stopped me before, at least with a desktop I can boot a PCI card and reflash if something goes wrong though...

 

Why not OC using something native like ntune or rivatuner? Also, the latest dox drivers are bugged. All the occlusion dos is cause glitches and slow frame rates.

 

Nvidia System Tools is Ntune now.
And the new Dox's are simply just not the best for your system. They make mine perform better.

 

You should acknowledge that this voids your warranty..or I thought it does

 

what viods your warrenty?

 

Overclocking your GPU.

 

Maybe, how would they prove it, and would they take the time too.

 

Donno, not gateway . But in the economy like this I would try anything to save some extra money .

 

Thanks again for the suggestions. Edit was made.

 

Yup. Nice little guide you've got there. +rep for taking the time to put it all together

 

Here are my results. Works nicely, and for $750.00 I can't really complain now can I?

 

Congrats Goodspeed.
How high'd you clock them? And which drivers are you using.
I got 9499points out of the 710/950/1750 clocks with 181.20 doxs.

 

Thanks man. I am using the as shipped drivers from Gateway. I clocked 720-970-1850.

 

Ohh. Nice. I'll have to try them clocks
Any heat problem with those?

 

Nope, no problems. I didn't even have the rear of the lappy "raised" this time for better cooling. I might even try higher, but I guess the big question is "WHY"? Other than bragging rights and of course FUN , it really doesn't mean all that much. So what I'm basically saying is: "I'm going to try it higher.".

Hey everybody, lets see some screenshots. As the saying goes- Pics, or it didn't happen.

 

here ya go and i guess this happened. not sure what it will do in games but i tried some higher settings and couldn't really get through the tests before the driver crapped out. Im using DOX 181.20 balanced. not sure what else i can do to make it get 10k

 

That's pretty good dude. Nice score.

 

not really sure what is holding me back i think it processor. just don't seem right i can't hit that 10 mark but o well it plays the games i want and doesn't seem to be getting as hot as my desktop gpu gets

 

Amen to that my friend. Enjoy it.

 

Are you running the 3Dmark06 with the Nvidia Control Panel open?
That'll put you back some points.
Make sure your only running 3Dmark06 when you run the test.

 

When i oc and run 3dmark06 the test never runs through because the of an error regarding the display driver.

I get the message "IDirect3DDevice9: resent failed:: Device lost (D3DERR_DEVICELOST)


Using DOX latest drivers.

 

I get the same error in Windows 7

 

It makes no sense though, at least in terms of heat, because I monitor it and it is not anywhere near an issue.

I'm in Vista though not 7, so it's not just that.

 

Im just afraid of overclocking because gateway doesnt allow acess to the fans. And i really dont want to have to buy a cooler. eh

 

Wow, anyone try this on XP? Both ntune and system performance tools seem to screw the pooch as soon as I accept the agreement. Screen gets all artifacted and can't do anything. Rebooting in safe mode and disabling the service and rebooting and uninstalling seems to be the only way to fix it...

 

Does this error occur with the factory supplied drivers and at default clock speeds?

 

K so XP users, if you have the problem I did I'd suggest ATItool .27b4, seems to work just fine. (At least with 179.28 betas from the nvidia site under notebooks)

 

That only happens to me if I switch around windows (say HW Monitor, I try to launch it at the last minute after hitting the Run Benchmark button on 3dmark06)

 

Scored 9800 (exactly, oddly enough) on 3dmark06 with 710gpu/940mem on XP, since I used atitool I believe it overclocks the shaders linked to the cpu, I didn't run a GPU-Z to see what they were at, but w/e, good enough score for me, on XP I suspect you could make a 10k run happen as I could have definately suicide clocked it higher.

 

Try reinstalling DirectX9.

 

I tryed to OC my stock with some settings I see here ,crysis crashed in 10 min
so I backed off some and no crash but I cant tell ant better play marks were 9201 OC from non OC 87XX

 

Yeah those clocks aren't going to work for everyone. Everyone knows you've got to find your own sweet spot with GPU clocks. The ones posted on here are great starting lines to try first.

 

Nice job BIG MIKE. Welcome to the club.

 

I really wish setfsb or clockgen or the like worked on these babies, I really think the P8400 has more in it, can't pad mod it either since its a 1066 chip...

 

Just any notes to people who try higher clocks..

If in the middle of a game (or I'm assuming anything that is loading the GPU) your performance drops drastically (if you have a monitor running you will probably notice the GPU is underclocking itself, even under load) then you are OC the GPU to much.

It took me awhile to figure out it was because I set my clocks too high.

 

yeah it dumps you to the medium 3d clocks i believe, ATI tool causes this to happen REAL fast if you have the wrong settings, you pretty much have to reboot when it happens, I think there's a way to restart the driver to get the clocks back but i forget how we used to do it.

 

I'm using Nvidia System Tools and you can just set your clocks back as easy as you set them up when you go over.

 

Excellent advice for those not in the know.

 

No, and it doesn't do it if I don't overclock much (lower than the initial suggested OC's). I'm thinking based on the fact my power brick has started hissing at times, that it's not getting enough power when I OC to those suggested started settings due to a faulty power supply. I mean I'm not positive but that's a possibility at least when it comes to me guessing. I'll be getting a hold of Gateway about a new power supply unit.
