9800m GT Overclocking

Ok, well try the GPU-Z method. Just hit the button next to BIOS version, then save the file to the desktop. Open the .bin file in NiBiTor, then let me know the Device ID listed under Adv. Info.

 

Same as at the 2 .rom, 10DE.063A.

 

No, the Device ID above those, is it 060B? That's what decides the name 9800M GT.

If not, change it to 060B. If it is try correct, try setting clocks then save it as a .rom and see if this one will flash with the correct GPU name.

 

oh sorry,. Yes, yes it is.

(But as I sad, I get the same error for the ORIGINAL bios too!)

 

Some1 with np5796+9800M GT would be so kind and share the overclocked VBIOS, which he uses?

 

I just found a 9800M GT on Ebay, but the interesting thing is the clocks which the card is running on :


That is a huge OC

 

where you find that one at?

 

Here you go: 9800M GT

 

nice...to bad i don't need a 9800m gt though...

 

Is it 100% stable at those clocks?

 

i dont' think it's stable running crysis at 1920x1200/high. longer than 10 minutes...(speculation of course)

 

the sellers sas: "it has been running for more than three months at 640/1600/2000", so I assume yes

+ seller is Powerseller and I don't think he would sell a card with unstable clocks.

 

I like the way he says it's mxm3... It's not even mxm III, it's MXM IV/HE,,,

 

it cames from a D900C!!! in D900C our card can reach that clocks.
If anyone will buy it without knowing it, he will have a lot of work to do!!

 

What? Doesnt the M57xU have the same card? What kind of "work" are you talking about?

kevin jack2.0, I was having the same problem flashing the 9800m on my MSI 627. I found the solution was this commandline "nvflash -6 newbios.rom". This tells nvflash to ignore the errror and flash anyway. Just remember this command line if you want to go back to your old bios. ie"nvflash -6 oldbios.rom" hope this helps you.

 

i have 8800m gtx in sli and would like to change their voltages through bios and overclock through software. it seems safe this way instead of permanently being stuch with high unstable clocks.

can someone explain how to adjust voltages in nibitor? i click on voltages tab and it brings up 4 levels of adustment and not sure what to change. this submenu is called "exact mode" and it has 4 options. "extra" is set to 1V, "3D" is set to 0.85V, and so are the last to options.

should the voltages be changed to 1.03 or 1.05 for the cards? in all 4 fields i mentioned above i see the option to select 1.05V but not 1.03V.

and how can i reflash the bios of the cards under windows? i have 2 cards so will need to know if it's better doing a dos flash via usb stick or in windows and how to flash both cards as well.

edit; nvm, i assume only you need to change the "extra" setting to 1.05V. i think i can handle this now.

 

Yes, the extra clocks shall be 1.05.

Dont flash in windows! Do it in real DOS.

 

yes i tried in dos but failed because the new nvflash 5.88 i downloaded is missing a file, the CWSDPMI file so not sure what's up with this. i downloaded an older nvflash 5.1 that does come with this file but i could not backup the bios first as it failed to find it on my SLI rig so am stuck now. i do not want to attempt to flash without backing up first.

 

ok i flashed the bios on both gpu's to the suggested clocks of 600 / 1500 / 950 with 1.05V. so far so good. gotta run some benchies.

as referance for others regardin SLI rigs;

nvflash -5 -6 -i0 yournewbios.rom

nvflash -5 -6 -i1 yournewbios.rom

the -i0 and -i1 represent gpu 1 and gpu 2.

do the same when backing up.

nvflash -b -i0 backup.rom

nvflash -b -i1 backup2.rom

edit again; just ran 3dmark06. i also upgraded to q960 3.0ghz cpu from my old q6600 2.4. with the gpu OC and the new cpu, the score went from 12,900 to 15,600. i think all is well and this score appears to be on par with others out there.

again edit to correct the numbers. it appeared that after the bios reflash the gpu overclocking software actually downclocked the cards to my safe stock volts of 550 / 1375 / 880. i deleted the software but forgot to reboot and these clocks were still in effect.

so....after the required reboot, 3dmark06 score is 16,097.

crysis internal benchmark went from 30 average fps to 36 in1920x1200 all high settings. this represents a 20% in fps improvement that matches the gpu OC %

 

im confused about this driver overclocking mentioned in the guide...
'2. Rivatuner or ATITool(To do a driver level overclock before the BIOS Flash)'

iv run riva tuner the max i can oc the drivers to is 575mhz 1150mhz and 455mhz

do i just push all those sliders to the max??? its still no were near what i saved the new bios settings at that i want to flash.

 

You can read out your old BIOS from GPU-Z, just click on the microchip next to the version number. Make sure you run the bios through nibitor first though, as GPU-Z saves as .bin and you need a .rom for nvflash to work (nibitor can convert it)

 

you wernt talking to me then were you??

 

nbitior read my 8800m gtx cards just fine. i did not need to pull the bios from gpu-z.

 

No, was talking to ARGH (in response to his earlier post).

Glad nibitor managed to read your bios, it doesn't seem to like vista/7 (or at least 64bit)

 

can n e one answer my question plz???

 

using crysis to test stability in-game and well, it aint stable at 600 / 1500 / 950 or is it stable at the 280m gtx clocks either. damndamndamndamndamndamndamndamndamn!

i do not run max fans as the system "should" be running max fans on the gpu's by default when they heat up...at least thats what the nibitor editor showed.

 

if you want to software OC use nvidia system tools 6.03 but you cannot go beyond 10% without more voltage.

 

right thanks, i can do it in ntune aswell cant i?? do i just move the sliders to match the hardware oc im doing ie 600 / 1500 / 950??

 

i think only the nvidia system tools allow software OC for our cards. in the past nothing software-related allowed it but now these system tools do. i do not know about other software that can also software OC so why not give system tools a chance?

also, you will not be able to reach or be anywehre near stable with those clocks without the volt mod through the bios. if going software only, try a 10% OC. 550 / 1375 / 880 and make sure you use crysis in-game scenarios to stress test.

 

thanks, yeah thats all iv managed so far on the software, gonna try the bios flash 2moz once i find my usb drive lol

 

you know the damn instability problems i encountering is just wierd because instead of artifacts on the screen, bsod, or hard freezes that i commonly think is associated with too much OC, i get the nvidia driver stopped responding. this error freezes the game, spits me back onto desktop with gargled boxes on the top left and i lose resolution mode forcing me into vga mode. then i attempt to reboot or shut it down and it freezes permanently there.

i have experienced this before even before any overclocking and it was dependant on drivers. i mostly experienced this when comming out of standby. it would lose resolution mode and dump me into vga forcing me to reboot if i could. i did experience it in games before but not to this extent. i mean right now, supremem commander and cyrsis crashes but darkfall does not running 600 / 1500 / 950 OC.

so wth.,....

 

Hi, try a driver from dox! I use the 185.20 driver and works very well with my oc set to 650,1625,950. And i think jou need to vmod the bios to 1.15 to trick the bios/driver and take the high overclock.

 

vmod what bios? highest i see in nibitor is 1.05V for the "extra" setting.

 

In nibitor under tools select voltage table editor. Set the 1.05v to 1.15v.
Go back to the voltages and set the (extra) 1.05v to 1.15v and flash the vbios!

It not always show the 1.15v then you need to select vid mode and then go back to exact mode and select the 1.15v.

 

when i type 'nvflash -4 -5 -6 -A -y yourbiosname.rom' (as in soviets guide) http://forum.notebookreview.com/showpost.php?p=4931771&postcount=14 the screen flickers and the computer restarts, wen it boots back in to windows and i pull up gpu-z to see if anything has happened all the clocks are the same still

iv also tried typing nvflash -4 -5 -6 yourbios.rom' and it the says...

'nvidia forceware utilit update
I/O error cannot open file'


am i typing the wrong thing??

 

No i dont think you type it wrong. I always save mij bios and name it newbios.rom in a map on the usb stick and name the map clevo.
And i keep a oldbios.rom on the stick for safety.

Keep the usb stick above the harddisk and pull it out when the bios screen pops up after the flash. I think this is the the most save way to flash my bios!

I flash like this: nvflash -4 -5 -6 newbios.rom
then y y if it look right.

What files are on your stick or cd and is nvflash working right!?

 

but isn't 1.15V way too much? this isn't a desktop. anyway, exactly how do you do this in the the table editor?
this is what mine looks like when first brought up and nothing touched.

 

it looks like the 20m gtx clocks ARE stable. i think when i mentioned last time they weren't it's because i had the clocks incorrect. i had 585 / 1483 when it should have been 585 / 1463 like 280m gtx that keeps the 1:2.5 ratio. keeping this ratio is a requirement to have stability.

 

The card is not running on this volts but you trick the bios/driver that its running at this volts, so you get a stable overclock!

The amount of active entries change it to 2, the entry 1: 0,85 vid 04
entry 2: 1,15 vid 00

This is the way it looks on my oc bios.

What is your bios nr? mine is 62.92.34.00.08

 

yes my bios version is same exact as yours then. so set the "extra" field in the exact mode tab to 1.15v?

can you elaborate how this only tricks the bios and does not actually run at this volt? what volt does it run then?

 

Read this thread page 5.

http://forum.notebookreview.com/showthread.php?t=261664&page=5&highlight=8800m+gtx+bios

 

the 1.15v trick did not work. it was not stable at 600 / 1500 / 950 so back i go to 280m gtx clocks of 585 / 1463 / 950 with 1.05v.

 

ok here are vids of my 2 attempts exactly how i did them dont worry they are only 2 mins long...

http://www.youtube.com/watch?v=0wK3UK69HR4

directly after that vid i rebooted in to win and checked out gpu-z, nothing had changed

second vid

any clues as to were im going wrong are gratley appreciated

 

ummm...how come you guys keep flashing with all them extra switches??

 

I think the name overclockbios.rom is to long! Keep is smaller like newbios or so.

johnksss: What do you meen?

 

well..when i use to flash my 9800m gtx's and my 9800m gt's
it was
this is for the np9262/clevo

nvflash -b 9800bu.rom
but needs to be ran in dos mode. (to backup the bios via dos)


nvflash 9800mgtx.rom
then hit yes twice. once for the first card and once for the second card. (sli only)
then reboot and your done.

those switches were for guys trying to flash a bios not meant for their card... 9800m gtx on a 9800m gt. 9800m gt on a 8800m gtx..

 

yeah i guess you are right if nibitor reads the bios correctly then there is no need to run those extra commands. i no longer do the -i0 and -i1 as the flash utility senses both cards and i just hit y twice.

i don't think there are any issues with using those extra commands, right? should i flash again using just newbios.rom and hitting y twice?

 

if it reads the card's strings correctly...then the extra commands shouldn't do anything...it was just added stuff that we didn't need...so i sort of cut them out of the equation a while back...
