GTX 280m possible working for D901C Owners

A few months ago, I experimented by flashing the GTX 280m vBIOS onto my system, and completed my experiment successfully. Today, I attempted to flash my GTX 280m vBIOS with the 9800m GTX vBIOS. The first thing I check was the system BIOS. Just as I though, it read 9800M GTX. A successful flash.
After reinstalling the drivers, I rebooted and ran GPU-Z and Everest Ultimate. Low and behold, they showed a 9800m GTX. However, this time, it had 128 shaders. I opened the nVidia System Tools module and changed the frequencies to that of a stock GTX 280m and ran 3DMark06. What did I score? 11602. Approximately 1000 points above the 9800m GTX.

What does this mean? This means it is extremely likely D901C users will be able to install the GTX 280m into their systems. I also assume it is safe to say that SLi would work also, since the card is detected as a 0617 9800M GTX.

Now all we need somebody to do is buy a GTX 280m and install it into their D901C and blind flash the 9800m GTX vBIOS onto it to prove my theory.

 

I thought Johnkiss bought a 280M for his NP9262 (D901C), but the MXM-III 2.1 version didn't have the SLI connector, so at best it would run a single 280M which wasn't worth it compared to 9800GTX in SLI and he returned it unopened.

Basically, it wasn't an issue of the 280M not working in the D901C, but moreso the inability to run in SLI.

 

I assume it would be possible to get a GTX 280m with an sli connector, since they run in SLi in the M980NU. Or... I see what your saying. The SLi version does not come in MXM 2.1 since the M980NU uses a newer version.

 

This was all part of Clevo's clever plan.

 

Aye, the 3.0B spec version has an SLI connector, whereas the 2.1 does not.

 

i discover that in any clevo driver inf has GTX 280M with strings for D901C so they have GTX 280M cards wich work on D901C but i dont know if the will release them

 

Could the higher benchmark score be due to the higher core and memory clock ? By flashing the 280 bio, essentially the card is overclocked.

On the screenshot, the clock is substantially higher than default one (582/800/1450 vs 500/799/1250). If you use normal bio, and overclock it to 280m GTX level, what's the 3Dmark06 score?

 

No, because it scores the same as when its flashed either way.

 

What's the same?

Like said, a ideal comparison would be your current system, vs a 570 with identical spec but true 280m GTX.

 

It scores the same as in my 9800m GTX scored 10550. My new GTX 280m scores 11600. The GTX 280m flashed as a 9800m GTX scores 11600. The 9800M GTX flashed as a GTX 280m scores 10500. Its not a matter of frequency. If the clocks remain the same, then it comes down to shader count to determine the difference in speed. And since I kept the same clocks between the two vBIOS flashes, it goes to prove the the GTX 280m flashed as a 9800m GTX is running all 128 shaders.

 

OMG I need help!!
I just bought a new 280mgtx for my 9262 from mxm-upgrade
and everytime i get into my system. the screen would just go black a few secs after i can see the home screen.
I think it might have been the bios. even thought i already flashed it from this link http://forum.notebookreview.com/showthread.php?t=416916
can u tell me which version of bios did u use to make 280m work?
thx so much!

 

Does the system boot with the previous card?

 

Try to boot in safemode to see what happens.

 

the previous card is fried. so i see a lot of colorful blocks on the screen.
and the laptop dies too. it could be some BIOS auto protection function going on
