so more hatin on Nvidia today.

From one of my recent threads some may be familiar with the D900 laptop which had an SLI setup and one of the cards was broken. Well today i decided that i have nothing to loose and decided to cook the broken 9800m GTX in an Oven!

The card was fixed to some degree, It no longer caused the computer to crash into oblivion when playing games and stuff. Altho i could still tell that the card was defective, At least it worked without problems. And i would like to keep it this way for as long as possible....
But the Nvidia Drivers and Software ISNT LETTING ME!

The broken/fixed/baked 9800m GTX is serving as a dauther board. The healthy 9800mGTX is the parent GPU. The parent GPU as far as i am concerned should be the main one in charge of the rendering and stuff. This obvious point is proved by the parent cards ability to function by itself without SLI.
YET! for some stupid bizzare reason, Nvidia drivers are locked in on the defective broken daughter card and COMPLETLEY IGNORE THE PARENT CARD. After a day of tinkering around with the D900 i came to a few conclusions.
1-The handicapped daugter card is always 10c hotter than the healthy parent card.
2-As i found out later its because the Nvidia drivers treat the impared daughter card as the main card. All the stuff it shows on the laptop screen is being streamed trough the daughter card, no matter if the SLI is turned on or turned off. If i turn off (in the hardware manager) the dauther card, the monitor goes black instead of switching to the parent card if its avaliable, and i have to restart the laptop. if i turn off the parent card, the daughter card just continues working as if nothing happened.
3- There is no way to switch to the parent card as being the main graphics processor unless i physicaly remove the daughter card.
4- the healthy parent card ISNT DOING ANY WORK! infact, its always just slightly warm while the daughter card is really hot.

Because Cooking the daughter card in the oven got it to back up to a very good working condition, I really dont want the daughter card to get all the load as overheating of the daughter card can break it again and cooking it in the oven a second time will likley do it more harm than good. So i really want to redirect all the major rendering traffic trough the healthy parent (which at the current moment isnt really doing anything as everything is directed trough the daughter card) and go a little easy on the broken dauther card so it can have a longer lifespan.

I tried Putting the defective daughter card in the Parent card slot, but i guess that part of the card is broken and the monitor wouldnt even work with it.

However, The SLI mode turned out to be even more amazing than the time before the dauther card broke for the second time! I tried running Skyrim on it and the results were as following. Single 9800m GTX could pull the game on medium settings with lags here and there. With a pair of 9800m GTXs the system still chose medium as reccomended settings but i found that i could run skyrim on ultra with no lag at all. Other games went better as well, exept for Crysis1 which couldnt run on very high without serios chugging. and dual sli 9800m GTXs could run it on the same level, as a single 512mb 8800m GTX but i think its because the crysis engine generally dosent like laptops.

So i really want to keep this somewhat functioning SLI for a while (at least untill i find a healthy working 9800m GTX) And the only way i can see this being done is forcing the system to use the Parent card as its primarey system videocard. But Nvidias Drivers wont let me. They attached themselved to the broken daughter card and exploit the poor thing to death.

So if anyone is familiar with this problem, can you tell me of a way i can make the Parent card into a primary system card? so the system will leave the broken daughter card alone so she might live longer? I have been screing around with drivers all day, I also screwed around with Riva tuner (maybe there is a way in riva tuner but i dont know the program that well therefore i couldnt find a way. I am about to download the NVIDIA BETA drivers to see if they unlocked the GPU priority choice.

I still hate Nvidia but i am starting to like this 9800mGTX which just refuses to die. also i love the D900 laptop too much to turn my back on Nvidia now, so i will have to fight trough all the Nvidias BS to protect what i love ^-^

For reference here is a pic. The 9800m GTX (2) on the right is the broken one and as shown in the picture, the system, monitor and stuff are all attached to the broken card on the right.

Maybe you should connect your monitor to the working one, cause from what I see it's connected to the broken one which may result in the driver thinking that that's your parent GPU.

its a laptop. i cant connect the screen to either one They are MXM4 Graphics modules. and so far i had no driver issues (other than not being able to make the Parent card as the primary system card like its supposed to but i think its more of Nvidia being a nazi rather than a driver issue)

The damaged card works really great, but overheating it may shorten its lifespan so i just want to make it easy for the card by not making it a primary card which its not even supposed to be according to my logic.

Wasnt there some software back in the day where you could manually spread the load? I also think that even though games support SLI and actually spread the load,they didn't really think about SLI in laptops so it might not function properly.

Well this one is actually very good with SLI in terms of performance. But I looked into this stuff in more detail and it gets really weird and confusing anout how MXM SLI works.
turns out The daughter GPU is actualy the Primary GPU Which is why my broken dauther GPU (GPU2) is getting most of the load. Also as it turns out, The GPUs status in MXM SLI is determined by the Vbios. And if you Switch the Vbios of the cards then that limitation is partially removed and this stuff just gets really confusing. Luckily i have experience with Flashing Nvidias Vbios before. Infact the two 8800m GTX cards that i have now, I Flaashed their Vbios before so both have identical Bioses. It has some thing to determine which card is primary even with identical vbios. Also the daugter card will not work from a parent MXM slot alone or SLI. So my Broken Dauther card as it turns out works like its supposed to, I used to think that these problems were signs of the somewhat dead GPU but i guess i was wrong.
Here is what i am gonna try to do. I am gonna attempt to Flash the daughter card Vbios, Maybe even carefully modify it. but i would really like to have the daughter bios placed in the father slot and work in the daughter mode because sine the daughter cards get the hottest its best to have them the farthest away from the CPU but right now its the closest to the CPU

Damn Nvidia you scary!
