9800m GT Overclocking

Most do. There are some that suck air out (which would be detractive to the clevos cooling system)

 

i am not really up to date on overclocking these mobile cards. do you still have to flash the bios on the 8800m gtx in order to overclock or is there finally software that can do this like desktops?

 

nope.... it's easy now

your over clock driver
http://www.nvidia.com/object/notebook_drivers.html

your software over clocking tools
http://www.nvidia.com/object/nvidia_system_tools_6.03.html

you can also flash your cards under windows if need be.
things have changed since you last embarked on this path...

 

finally! lol. now i have to get myself educated on oc. is there a common overclock (not extreme) for the 8800m gtx out there?

 

sure. 600/900/1550
but you should be able to run the gtx280m clocks. (585/950/1463)

 

what about voltage adjustments? and since i have sli i need to oc both cards, right?

 

looks like the voltages are greyed out in the software. i will see if i can hit the clocks you suggested.

 

you know what...
bios flash your cards to 1.03 voltage and that's it. leave everything else stock.
then use the over clocking software.

 

yeah i would probably have to do something like that because (585/950/1463) clocks hard crashed almost immediately trying to load crysis.

how would i go about doing a bios reflash?

 

Not all clock setting work for everyone. As I said in other posts, for example my memories won't go beyond 860, I get constat artifacting and even crashes in aero so I run them at 850. In my case, the core/shaders can be pumped to over 620/1550 but the card starts to get too hot IMO at those clocks.

 

so you are at stock voltages?

 

crysis really doesn't like to be over clocked period in a laptop. it starts thinking your card is a desktop card and pushes it like it is one.

before trying to run these clocks you will need to flash the higher voltage.


and blacky, i would either reflash my stock bios or reflash a stock bios on to your card. if that doesn't work i would send it in for repair, because your card is broke. either by bios or the card itself. no way would i even entertain keeping a 700 dollar card that went up 50 mhz on memory(for an over clock). (ati not included). sorry....

 

ARGH: Yes, I am running stock voltages that are 1.03V . I have also tried with higher voltages 1.05V but I haven't noticed much of a difference; however that requires a different BIOS for my card on which I lose the HDMI support which I actually need.

johnkss: I completely agree with you. I have tried stock BIOS, 0617 BIOS, you name it, the memories don't like to go above 860. I have been thinking of sending it back, but what I am to tell them? Hi, look, overclocking doesn't work properly... I live in Europe and here overclocking voids your warranty as far as I know and I think it's the same everywhere.

And yes, 9800M GTX has been a rip off for me in terms of money/performance ratio not to mention that my subsystem ID is not even supported in the official 179.48 drivers.

My only option that I can see now is asking for an upgrade from my reseller, to the 280M, although from my experience now with Nvidia, I would rather get the 4870 (too bad ATI has poor driver support).

My biggest regret right now is that I didn't choose the 9800M GTS instead of the GTX.

 

there isn't much of a performance increase over the 8800m gtx / 9800m gt by going with the 9800m gtx unless you are in sli and a game (like crysis) requires more than 512mb video ram to run in high settings and high resolutions to avoid micro stuttering. for me, 512mb vram is not enough and i wish there was an upgrade path from sager to the 9800m gtx but there isn't unless i fork over $2k for both cards

 

1. i wouldn't choose a 9800m gts over a 9800m gtx.
2: what do you mean it doesn't support your card? it has all the 9800m's in there
3: when you flashed your card, did you change anything other than what you we're suppose to change??

and as for 9800m gt being close to a 9800m gtx...nope.i had dual gt's. they didn't do the job, so i upgraded to 9800m gtx's. and been cool ever since.

 

2. Not all 9800M are supported. My subsystem is not supported so installation just won't get through. I can try the have disk method but then HDMI won't install properly then. I have sent a feedback to Nvidia telling them my subsystem is not supported.

3. Ahhh... but I flashed my card so many times I can't remember. What I do remember is that from the very begining when I got it, sometime in mid December memories wouldn't go above 850 regardless of what I have tried. They won't go regardless of what BIOS I try. Everything else works fine.

 

interesting...there are like 2 id strings 0608 0617(sli)
it's because your string id's are messed up and the timings for your card are as well. your probably using the default of timeset 0

you need to flash it back to the original bios and id strings

post up a gpuz pic and lets see what we can get done...im not sold on you be stuck at 850 mhz yet...if you got about 30 minutes, when can try to get it sorted out.

in nibtor for a single 9800m gtx early edition.
0608
1558
0902
8823
voltage 1.03

9800m gtx last edition
0617
1558
0902
8823
voltage 1.05

your card is located in the nvcv.inf file of the install directory.
in this file there are 2 listings for your card. delete the second one.
save file then do the install and it will work fine.

that's if you didn't mess up your id strings to begin with..
these are not your card
0617
1558
0481
8823

0608
1558
0481
8823

 

Alright, here is my DEV ID:

PCI\VEN_10DE&DEV_0608&SUBSYS_04811558&REV_A2

And I actually do not have my original BIOS. I have an original 0617 BIOS and I also have an original 0608 BIOS from someone else on this forum if I recall well.

That's all. You want a picture of the timmings ?

 

ok, what your gonna need to do now is flash your card to the

so it looks like this
device id = 101e-0617
PCI\VEN_10DE&DEV_0617&SUBSYS_09021558

you do remember how to flash so that the strings change as well right?

 

Well, actually I do not know how to flash to change the strings .

But how am I suppose to flash? My original BIOS is 0608 so it can't be 0617, on 0617 I lose HDMI support.

 

you lost hdmi because you have to sort of re detect it if im not mistaken.
emike is running the 0617 and has hdmi working so im gonna have to say it works...
but if you didn't flash the whole string to the new bios, you never really flashed it to the true 0617 then. you need all 4 lines of id to match up.

give me a few to find the flash codes.

 

If HDMI is working on the 0617 then I will move to 0617 indefinitely. I will wait for your reply.

 

nvflash -4 -5 -6 whateveryourromis.rom


start here and read through. it tells of someone with hdmi working.

i have not attempted to flash the bios for voltages and i am not sure i will, but i did a 10% overclock accross the board, 550/880/1375 and stable so far with a few bench runs of crysis wuxga all high settings. the 10% oc resulted in a 5% fps gain from stock clocks.

the 600/900/1550 clocks is a beefy 20% overclock. how relatively safe do you think this is? anyone fried their cards at these numbers? also, crysis should be used as the main stability test as this games takes my gpu temps into the 90c territory even at stock clocks.

 

That's exactly the string I have been using. I will try to flash again then.
Everytime I flash it tells me the subsystem is different and it will overwrite it. And nvflash does show a different subsystem 1558 I think.
However, even after I flash, the system still sees the device ID at the one I have shown above (04811558).

I know it doesn;t make sens, but that's exactly how it happens.

 

Alright, 5 minutes after the new flash with a brand new stock 0617 BIOS and system hasn't crashed yet. But I think it will any time soon.

Here is how things look now. I have also included a picture of the BIOS info used to flash.

Do you think now it's alright ?

 

i fell asleep guys.. but im back now..

argh. you should be fine with that over clock, if not...you can always drop it down even further...

blacky...now you have me at a loss...i thought when you flash with using that command, it changed all your sub string id's. but yet yours shows the old id big as day.

 

Exactly my problem. That's what I wanted to show and I have no idea why.
By the way, my system hasn't crashed yet which is good news and I also got the official 179.48 drivers installed.

I guess no one knows why I can't change my subsystem ID .

 

hummm....

well that's a good thing... no crash

what are your clocks at now. still 600/900/1500?

 

I kept the OC clocks 600/1500/900.

I've also ran 3dmark06 and it went through fine, gave me 10050 which is pretty low, I used to get 10200.

I don't have any game around to test how the card behaves under stress nor the time to try it out right now.

Well I also need to sleep, it's getting late here. Thnx for the help.

 

you would get even higher running just vista.

im testing the latest version of windows 7 and the scores seem to be lower.

 

how do you extract the vbios from a system with sli like ours, johnksss? and how would you flash both cards as well with nvflash? also, how you like them 9800m gtx's with 1 gig of video ram compared to the 8800m gtx / 9800m gt?

 

you can use gpuz to get it
then use nibitor to open it.

once you get the right vbios on the card. you type
nvflash 9800mgtx.rom then hit the y key twice. and that's it.

love them thus far. they take a lickin' and keep on tickin'..

 

so then i assume that both cards will have the exact same bios right? if so then i only need to extract one bios from either card.

 

that is correct.
the 9262 has a master and slave card slot. not a master and slave bios.

 

Going back to my previous post here. When I try to flash again my BIOS nvflash shows me that the BIOS that I have installed has indeed the subsystem shown in Nbitor not the 04811 but it also tells me that the subsystem of the BIOS is not compatible with the adapter subsystem. This means that the subsystem in the BIOS does change but somehow, the system does not report the BIOS subsystem but... something else, which is at least to say interesting.

About the score in Windows 7, with this new built, after installing DOX 182.05 I got a bit more than 10200 running 604/1510/850 . After that I installed the official drivers for Windows 7 and it all went to hell. Scores dropped to 9800 and didn't wanna go up again ever since. I tried to do a clean driver install, used driver sweeper and all that but didn't help. Right now I get 10050 but it's probably because of the BIOS cause I know the 0617 BIOS gives about 300 points more over the 0608 BIOS.

 

I just installed the latest DOX drivers, 182.46 and it took about 10 minutes for the system to crash. I reverted now to the official 179.48 drivers as those haven't crashed yet in any circumstances.

 

New Windows 7 official drivers perform crappy in 3DMark, but it way better then any athers drivers for real gaming, way better than DOX 182.05

 

I don't mind so much about 3dmark06, but I do mind that in the official windows 7 drivers you can't enable Nvidia scaling which is a serious issue, for me at least.

 

Hey Blacky, did you get 181.71 to install without BSOD? If you have a working copy, will you upload it for me?

 

Why not get it straight from Microsoft, that's where I got mine .

Here's the link for your card, if your subsystem is not supported delete it from the inf and just leave the device and it will install fine.

http://catalog.update.microsoft.com...updateid=073f15b3-2aaa-4538-9a44-e58f902454a0

and for other cards as well:
http://catalog.update.microsoft.com/v7/site/Search.aspx?q=9800M

Enjoy.

 

Hmm yeah I've been trying to install that one, but it tells me that it can't locate any compatible hardware.

Delete what to get it to install?

 

Just change the .inf file then. Go into the file, search for your device ID and delete the subsystem. It will install fine after that.

I had the same issue on my 9800M GTX and that was my solution.

 

Hi!
I tried to flash my 9800M GT in my np5796 to a new BIOS with nvflash, but I got this error (I copied this from an other forum, but it is the same with different values):

NVIDIA Firmware Update Utility (Version 5.72)

Checking for matches between display adapter(s) and image(s)...

Adapter: GeForce 7900 GTX (10DE,0290,3842,C570) H:N B:01,PCI,D:00,F:00
WARNING: Firmware image PCI Subsystem ID (10DE.040D)
does not match adapter PCI Subsystem ID (3842.C570).
WARNING: Firmware image Board ID (7129) does not match adapter Board ID (7100).

ERROR: PCI subsystem ID mismatch

what is this? Why do I get this error with the new and even with both the old (I saved one with Everest and one with nvflash -b ), original BIOS?

 

What device ID did you set in NiBitor?

 

I only changed freqs, when I opened the BIOS in nibitor, it allready saw it as 9800M GT...but the strange thing is that it writes the same thing for the (2) original bios (I dumped them myself, 1 with Everest and 1 with Nvflash...same problem with both lol).

 

are you sure you don't have a 7900 GTX ?????????
From this error you don't have a 9800M GT !!!

 

"(I copied this from an other forum, but it is the same with different values):"

Have you ever saw a 7900 GTX in a Sager np5796 (m570TU) ?

ps.: I checked again, these are my values:
"Warning : Firmware image PCI subsystem ID ( 10DE.063A)
does not match adapter PCI subsystem ID ( 1558.0481).
Error : PCI subsystem ID mismatch."

 

Did you get the BIOS by dumping the .bin from GPU-Z?

 

nope, I dumped .rom with NVflash and with Everest too.
