Guide to flash 9800m GS to GTS

ok, and any suggestions on my problem?

 

If you keep getting errors, it could be a driver error. Do you still see those errors with different drivers?

 

@MichelAsus

Well....that errors implies that

a) you're overclocking too much
b) you're overheating
c) you're undervolting too much

Extract the vBIOS via GPU-Z (green thing to the right of the BIOS revision number) and then upload it to rapidshare and I'll take a look at it and see if the old GPU was flashed or not.

 

thank you TevashSzat
here is my bios.
http://rapidshare.com/files/268936202/G94_M.bin.html

a) I haven't overclocked anything.
b) I haven't felt any overheating
c) I haven't touch any voltage

 

The vBIOS is the stock 9800M GS one. It has not been flashed to GTS clocks or voltages.

I suspect then that it is due to overheating problems.

What are your max temps after one 3DMark06 run? Use HWMonitor for the temps.

 

ok I will run 3DMark06 and I will tell you the temps but I don't know if that is the reason because the computer freezes and bsod's appear when I tried to use the gpu like using Aero and opening a few programs or Cod4 loading into the game.

but I will try it.

 

Oh, can you give me the error that pops up in the BSOD too?

 

it's NVLDDMKM.SYS
sometimes the code is 0x000000116, sometimes 0x000000117, 0x000000c2.

can you tell me what code do you need exactly?

 

Okay.....that is the driver file......hmm......that could still mean that you're overheating or that your video drivers are off. Have you changed drivers yet?

How about this.....why don't you just change your drivers and then see what happens. If you look at my guide (look at sig), there is a part with instructions on how to do so.

 

Sigh. I'm chopped liver.

 

I already tried changing drivers, when I updated them to a newer version the BSOD appears on boot, I can't acces windows I have to unistall from safe mode, the drivers that i'm currently using are 179.14.

sorry I didn't saw your post :s I already tried changing drivers.

 

Okay......doubtful that it is overheating then......I would probably then just contact whomever you bought the laptop from and then ask for a RMA

 

:S :S I was wishing for a easy solution, will be difficult because I bought the laptop in the USA and I live in Guatemala, I had like 2 months of warranty I will have to find a solution for sending it.

another solution?? In other forums I read about undervolting? underclocking? this can really fix something?

 

If your card isn't stable at regular clocks overclocking and undervolting will probably only make it worse.

 

really? I didn't knew that ok so I think I'll have to apply warranty. :s

 

I've experienced few other things!

I've ran GTS clocks with 1.05 Voltage. Not all 9800m GS chips will be able to do that. I am guessing I have a very stable chip because my X8TW from Newegg came with 1.11 Voltage stock which is GTS's voltage and that's the reason it's very stable even beyond GTS clocks.

Currently, I am running my 9800m GS at stock clocks 530|1325|800, but at 1V. I've tried 560|1400|800 clocks at 1V and it runs perfectly fine with no artifacts for 20 mins using ATITool and Furmark running simultaneously.

This is by far the best settings for me because the max temp it reaches when stressed for 15 mins in Furmark is 87C. (Room Temp 73C) In various games, it stays in high 70s and low 80s and I am very comfortable with these temps.

The thing about the 9800M GTS is that it only has 64 shaders meaning that the card won't be using as much power compared to say the GTX 280M at the same clocks. Whether it be the G92 or G94 variant of the 9800M GTS, the natively available option for 1.11v, a cooler thermal envelope, and a lower number of shaders to power allows the 9800M GTS to push to very high clocks. I have seen Clevo users with the 9800M GTS push their cards way high to clocks even I wouldn't dare flash onto my card, and remain stable over 85*C for a long period of time.

 

Oh, big time! Don't forget that many people with G50VTs can't even run the 9800m GS at GTS clocks. So... Those people who pushed their GS's beyond GTS clocks are simply lucky to have a very stable chip like I have.

I've ran my 9800m GS at GTS clocks on 1.05v. Most people can't even come close to that. I've read "Clutch X2" said his chip had arrived at 1.11v. Mine came exactly the same way. At first, I was kind of concerned, but then I figured that's actually really good because 1.11v is GTS's.

Perhaps, I should flash it to 1.11v and see how far I can push with Ntools.

EDIT: Installed DOX 185.85 drivers for the first time and it took about 6-7 mins in Furmark to get to 85c and couple more mins to get to 86c and that was the max for about 12 mins.

Sorry for double posting, but I think it's well worth it.

Success #3
I've flashed my 9800m GS back to default 1.11v and tried the following clocks: 600|1500|800 and then used NTools to overclock it to 650|1625|800

I've ran 3dMark 06 on 1280x768 res and this is the result:


I was bit concerned about temps as it reached 88C. That's perhaps too high for me. While I was running 530|1325|800 on 1v, it was at least 4-6C lower.

Furmark will definitely push it beyond 90c as it was getting there with 1.05v 560|1400|800 clocks.

But at 530|1325|800 1v, it stays around 86c and pretty much never goes higher.

I have a silly question. Let's say I have a 9800m gt that isn't fully utilize because of power constraints. But the notebook runs a 9800m gs just fine. Could I flash the 9800m GT to a GS? I know that the gt has 96 shaders, and the gs has 64. I don't care if I loose shaders, I just want to know if it's possible without totally killing the card.

 

BIOS doesn't remove shaders, it would just underclock them.

I'm not sure what you mean by "power constraints", though. Do you mean you want more battery life or the GT isn't getting enough voltage?

 

I think he means something like this: http://forums.laptopvideo2go.com/topic/18776-nvidia-8400m-gs-modding/


Edit the Device ID of GT to GS perhaps? In return, it should only use 64 shaders???

 

No. The GPU BIOS has no control over the shaders. The BIOS will just think that it's a very special 9800M GS as use all 96 shaders.

 

Thats a very nice 9800M gs u got there, If your GPU can run at GTS speed with 1.05v, why bother risking going with higher voltages? 88C sounds a bit too high. I have tried 570/1425/800 at 1.05v and it ran my games fine so far, but in a 3dmark06 test, i got a driver error that shut down the test, dont know if its becuz the GPU cant handle the higher clocks since i got the same error before without OC, i think i am gonna make more tests and see if i can push it card to GTS speed while still keeping the voltages running at 1.05v.

 

I've flashed it to GTS clocks @ 1.05v and it runs super stable.

-Leonid

 

Thats good to hear. Whats your max load temp at GTS speed?

 

Well, Playing crysis gets close to close to 90c, high 80s...

Just for the heck of it, I've flashed the extra to 0.8v and running 520|1300|800 for about 10 mins under stress.(AtiTool) So far, no errors...

 

Well, that seems a bit high. And running extra at 0.8v? its crazy, 520/1300/800 is very close to the default clocks of 530/1325/800, u could probably run the default clocks at that voltage.

 

I actually was running it at 540/1350/800 stable for 5 mins and decided to go for 500/1250/800. (8800m GTS clocks ) and whenever I'll need more power, I'll just bump it up to 530/1325/800. I might just flash it to the default clocks, but I gotta go to sleep. *_*

EDIT: crysis for 5mins max temp 80c. Ambient temp 77f.

-Leonid

 

So it can be done? i can safely flash to a 9800m gs and then flash back to a 9800m gt if I wanted to?

 

I don't know. The only way to find out is to try it yourself. I know that I can flash my GTX 280M with a GTX 260M, 9800M GTX, GT, and the G92 variant of the GTS successfully. But in your case, Darth Bane, the 9800M GS is a G94, so I can't guarantee that flashing your GT to a GS will be successful. You can always flash back if it doesn't work.

 

thanks. So even if it does fail, i can still do a blind flash....

Does anyone know where I can find a 9800m gs bios? Is there anything fundamentally different between the GTS and GS bios besides voltage differences? If i can't find a GS bios (dont think asus version will work), I could try a GTS bios and just lower the voltage....

 

Providing that you have memorized the proper force flash command, yes.

 

Wait a few minutes.... nvflash -4 -5 -6 xxx.rom

right?

I've already flashed my gt a billion times trying to fix my issue.

 

The proper force flash command is "nvflash -4 -5 -6 -A -y name.rom."

 

what does the -a -y do?

edit: nevermind, found it.

 

The parameters are case sensitive. Be sure you type -A in uppercase.

 

thank you. I flashed and got a nice black screen (heard windows boot). But I only needed to try "nvflash -4 -5 -6 -A -y name.rom" once to get it back working.

 

Oh well. Atleast we know we can't flash a G92 with a G94 BIOS. Nice try though.

 

Why don't you simply under-volt and under-clock it, instead of trying to flash your GT to GS bios!?

e.g. I am running my GS at 530/1325/800 at 0.85v, but I can even go 0.8v, instead I decided to stick with 0.85v.

 

Did you see a noticable drop in temp while running at 0.85v? I have seen many ppl noticed a huge temp drop(>10 C) by Uving their GPUs, i dont get why my 9800M GS only dropped like 2C after a massive UV.

 

While playing crysis, I haven't seen it go above 86c (77f ambient temp). Now, in other games such as burnout paradise, Wanted, which I've played; temps hover around high 70s and low 80s. Now, if it were in winter time, I'd definitely see lower temps.

Actually, it's impossible to have 10c drop in temp even if you undervolt, unless with cooler or your room temp is below 65f. Those 64 SPs need some juice in order to run.

EDIT: Just for the heck of it... When I underclock the memory clock to say 300mhz, in furmark the max temp drops from 91c to 78c. (ambient temp 77f)

 

Come to think of it, it makes sense those cards that have huge drop in temp after UV are mid/low range ones, since they have low TDP and less SPs and don't produce lots of heat, the effect of UV on the temp drop should be greater.

I just tried OCing my 9800M GS at 1.05v and the result wasnt good, i kept getting the error message "driver stopped responding and has successfully restored", no BSOD so far though. I googled a bit and found many people have this problem even without OCing, many of them believe its the insufficient power supply causes this problem. Looks like raising the voltage is the only choice for me if i wanna run the card at GTS speed, very few of us are lucky enough to run at GTS speed with 1.05V, u are one of them.

 

Actually, I am able to run my GS at 620/1550/800 @ 1.05v with no Issues whatsoever. Of course, temps increase at least 1-4c, but that's expected.

Damn! Consider youself a very lucky owner of G50VT!! And 10257 for 3dmark06?? Thats at the level of a GTX260M!! I wish my 9800M GS was as good as yours.

And is it true that different G50VT models have different default voltages for their 9800M GS? Mine runs at 1.05v for Extra, yours is at 1.11V, right? Don't know the reason behind this, anybody could throw in a possible explanation?

 

That's some score you've got.
Damn, I'm having regrets for selling my G50Vt away, I have yet to find a laptop to match it.

 

At how much OC was done to your CPU? I'm only getting some 9.45k-ish with my X5, but that's with its stock P7450 @ 2.13Ghz.

 

You can clearly see in the screenshot his p8600 was OCed to 2.64 Ghz. And be aware also his 3dmark06 was tested at 1280x768.

 

My laptop came with the default voltage for Extra at 1.11v which is GTS's voltage. Now, I've purposely took it down because I knew GS's stock voltage is supposed to be at 1.05v. Then I began experimenting with my GS and I found out that I can ran the chip beyond GTS clocks at 1.05v.

It's believed that if your chip arrives at 1.11v then your ability to overclock the chip is supposed to be bit more stable even at lower voltages, as "Clutch X2" mentioned in one of his posts.
