9800m GT Overclocking

Edit808 yes I overclock my SLI 8800m GTX. However I don´t need to flash anything since I can overclock my 8800m GTX to 625/1550/950 max out of the box and with software overclocking only and artifact free in ATI tool.

A tip! always check ATI tool when you have overclocked, even if you don´t find any artifacts in game, ATI tool do discover artifacts the bare eye can´t see, namely deltas if there is not enough voltage or due to heat. I have seen other M1730 owners overclocking their 8800m GTX SLI to 670/1670/980 and say it runs fine when they haven´t even checked ATI tool to see if there is any deltas when there definitely is because that kind of overclock needs overvoltage to the GPU´s Running with Deltas is bad since it will basically destroy your GPU.

Dexgo I think had to raise voltage and flash to come up with the almost the same overclock. Or if I remember correctly he only came up to 600/1500/950 with a overvoltage. Not sure how the 9800m GT handles it though if you need to overvolt there too in Nibitor or if Ntune works for it too.

My overclock sticks everytime I reboot and with System Tools 6.02 I can adjust the Shader clock separately from the Core clock.

 

Ha magnus thanks for replying, and giving your info. Just out of curiosity what was your 3dmark06 score with your current configuration. I never got to see it. Been away for awhile and just recently got back.

 

Well since I am CPU limited in 3D Mark 06. My 3D Mark 06 score were 10960 at 1280x800. If I had an extreme CPU I would get a higher score. However when I ran 3D Mark 06 at 1920x1200 I got around 10000 in 3D Mark 06 so that tells something, at 1920x1200 I am not as CPU limited as in 1280x800

 

Well I've successfully flashed my 9800 to 610/1525/945. Ran 3dmark06 and scored 9871, and played some Mass Effect. Temps maxed at 82°C.

 

are you serious?????????????

and all you scored was 9871 with a 9800m gt?????????? something is seriously wrong with your system.

 

That sounds almost about right. With his CPU at least. I think it should be up a couple hundred points, but its not that low. Some of us aren't running crazy quad core sli systems...

 

Yep, his score is about right for his CPU.

 

who? where? who got a quad? *LOL* is it friday and i missed it?

but seriously. i ran a slight over clock on the 9800m gts and it netted 10,500 easy

right for what? stock no over clock maybe. *L*

edit: maybe i should have asked what cpu he had first......hummmmmmm
nope p8600 with 3 meg cache 2.4 ghz

 

What CPU do you have though.. he has a lower clocked CPU, when the benchmark is CPU limited. Obviously he'd get a considerably lower score.

 

ok, his score was more of a big surprise than me trying to put his setup down. i apologize kevin! did not mean it like that.

my cpu at the time was an x9000 ran stock at 2.8
and i looked at my 2.26 test and it pulled in at:
9541 3DMarks

SM 2.0 Score
4454
SM 3.0 Score
4541
CPU Score
2054

but it was heavily overclocked though.
and we are talking about my 7811fx

 

could someone please explain how to over clock the 9800 gt i have no clue how to do it. i have never overclocked in my life. if u could put it in numeric order then i would greatly appreciate it. my specs are as follows
NP8660
64 bit Vista
15.4" WSXGA+ "Glare Type" (1680x1050)
Intel® P9500 45nm "Montevina" (2.53ghz)
Nvidia 9800GT 512mb
4,096MB DDR3 1066MHz Dual Channel
2 GB Intel® Robson Turbo Memory
500GB 5400 RPM hard drive

 

well....ummmm.... that's not very promising..... because if something goes wrong....your pretty much out of luck. you sure you want to go down this path?

 

chidesd, if you have no experience in overclocking, a BIOs flash (which can brick your GPU) is the last thing you want to do.

 

it's not so much as bricking it, but trying to get it un bricked because you didn't have the right tools and know how to fix it. this is a major part of flashing and if you do not have a usb floppy or usb flash drive. (i stress usb floppy!!!) then i would not be trying it if i we're you.

 

Most people that brick a GPU freak out and think its hopeless, plus you can still seriously damage it if you go too high (i.e. flash your voltage too high)

 

yeah this is why i need info on ocing. i wont do it unless i know what im doing but i cant ffind any solid info about how to do it.

 

you really dont need to over clock the voltage unless your trying to seriously go for records. (personal opinion) better than average over clocks run fine with the standard voltage.

 

I dont like to admitte it but i dont completely understand. i know nothing about ocing. i just need a good guide to read and study so i can do it my self. but i do know what u mean about the voltage.

 

No, you were actually right. I figured I had messed something up in Nibitor because my card was being identified as an 8800M GTX. So I reflashed oldbios.rom because it seemed like the card was downclocking, then I created a proper bios @ 610/1525/945. My new flash scores about 10100 depending on the driver.

 

ok, now we are looking more closer to right!

WTG kevin!

 

is there any good guides on Ocing around?

 

Thanks. I wouldn't have looked into it if you hadn't said something.

Is 610 really the max for the core on this thing? +11 doesn't seem like much of an OC, when I could go +165 on the core of my old 8600m GT. Admittedly, I know very little about the G92 chips.

see post #148.

 

thanks alot i will review this post. and if i have any queations ill post em up before i start doing anything.

 

does OCing void the warranty on your gfx card?

 

Yes. But that usually depends on how much, and which manufacturer. Straight from Nvidia, I believe it voids it.

Desktop cards from different re-sellers (i.e. BFG, PNY) are a different story.

 

just depends...it's best to do software over clocks and find the right set of numbers. then flash for a permenant solution. that way your not constanly flashing the bios.

 

There is currently no software that supports the 9800m GT, so BIOs flashing is your only solution.

Definite safe clocks:

600/930/1500

1.05v

I've seen people go higher, but for whatever reason my video card driver ****s up if I go higher and randomly fails according to vista.

 

but when u flasg the bios u use the same numbers as if u were ocing with software?

 

so no software over clocking of 9800m gtx's either?

 

can someone post another safe OC. plz when i go to edit under river tools non of my settings wont go up to600/930/1500? why is that? is it because of the drivers im using? im using doxes customized driver.

 

What is river tools, post a link.

The closest thing I can think of is Riva tuner, which does NOT support the 9800m GT/GTX, using this can seriously **** up your GPU because its NOT giving you real values. I cannot stress this enough, if you don't know what you're doing, DO NOT OVERCLOCK.

And yes, 9800m GTX has no software overclocking either.


If you're completely dead set on this, I'll point you to a few things


GPU-Z for checking your stats on your GPU (clock speeds and such)
Nibitor for modifying GPU BIOs
Nvflash for flashing the BIOs


The rest is up to you, google, and the search button on this forum (because the method has been described, in detail in this thread)

 

ok thanks. i guess ill wait until there is some type of software that is supported with my gfx card because i would rather be safe then sorry. sorry about misspelling Riva tuner.

 

well here is the time to test my theroy. i posted it in another thread but not sure if anyone has tried it yet.

you do have ntune 6.02 installed with the performance settings?

 

Ntune will only overclock shaders.

No core, memory, or voltage.

 

no i dont have ntune installed. i guess i wont oc yet i will have to wait for software support because i dont feel comfortable flashing with a given number, i would rather test to see the best settings for me.

 

C:\Users\(your user name here)\AppData\Local\NVIDIA Corporation\nTune\Profiles

in there they will have the settings.
open the osbootpf file with notepad and change the core and memory clocks. make sure the shaders are always twice as high as the core or it wont take as well. then save file as is osbootpf.nsu. now double click on it and it should try to set the clocks to the new settings.

 

o so u can software oc with this card?

 

dont know. i mean...if i dont hear an answer by friday. i will have the answer myself...lol

 

so ur saying u r going to test this method ur self?

 

Having that unoptimized crap installed lowers my FPS by 5 in Crysis anyway, I'm not re-installing it to try.

Ntune is right up there for me with Norton Anti-virus in terms of 'most badly coded software ever'

 

you dont really need it installed to begin with. just the file that i mentioned.

edit: and ntune is nowhere even remotely close to how bad norton or mcafee are!. *LOL*

you just needed to mess with the ntune settings and all would have been fine. when first installed it installs in high quality mode, so of course it's some fps lost.

 

so has your method been tested?

 

sure. it's been tested...just not on a 9800m gt or gtx. works fine on a 9800m gts. i dont have my gt's in hand so i cant tell you if it's going to work just yet.

this just happens to be for my gtx280
but it's the same for just about all vga cards.

 

hmm... if it works on a GTS it should work on the GT.

Same core isn't it?

 

we;; i guess ill try your methiod with the specs from clyzm.

 

different cores, but all it's going to do is either change your clocks or say your clocks haven't been changed.

yes, you can use a simple OC just to see if it's going to work. it will be my first method of over clocking before i get to bios over clocking. that's if it works...*LOL*

 

yeah sounds good ill try it and see what happens thanks

 

Just make sure you have proper cooling for the thing...

Your GPU shouldn't be hitting above 85 degrees under load.. and not even that if you want your laptop to last a long time.

 

simple over clock meaning..
stock 500/800/1250
oc 550/850/1300

dont think that will stress him out any....

 

Yeah but I mean generally... some people are hitting 80 degrees without any overclock at all, and I don't consider those safe temps for overclocking.


Doesn't hurt to be safe about it.
