GTX 285M Bios Please?

Is any owner of this card willing to upload their bios for me? Id really like to take a look at it.. Pretty please with cherries on top ?

 

Or screenshots of all the values and settings in nibitor would also do..

 

Noone out there with a 285m willing to do this?

 

This is all I am willing to do... sorry...very stock as you can see

 

This doesnt really do so much for me.. but thanks anyway..
Can anyone send me a .bin or .rom bios file or do actual screenies of the bios in nibitor?

 

wow, why yours is G92-ES?

 

G92-ES is the codename for the GTX 285M on the old .inf's, including the one on the Clevo tailored 187.71.

 

will upload in around an hour:

GTX285.ROM

Use at your own risk I take no responsibility if you screw your GPU up.

I also advise you check what GTX280M you have this will not work on most

 

Thanks, ill finish my research (annoy people whove done it ) first..
What do you mean with which 280m i have though? - do you mean if its MXM 2.1 or 3.0?

 

Hello,

From messing about today the GTX280M 2.1 can't handle 600 / 1000 / 1500 so no point flashing. The 3.0 seems to be fine with the new GTX285M bios 2 D900F units flashed from GTX280M to GTX285M and all seem stable up to now.

Not sure if the voltage was changed in the 2.1 the clocks would become stable and the GTX285M flash would work if the RAM timings matched the GTX280M timings (I need the GPU so cant risk losing it)

 

The MXM 2.1 main problem is its hard time to get the GDDR to work above 800 Mhz. Although it can be pushed further to 900-950. The main difference between the MXM 2.1 and 3.0 (besides the form factor) is that the MXM 3.0 can support cards up to 100W while the 2.1 is designed only for 75W. The ability to draw more power plays a major role in the ability of MXM 3.0 card to overclock to higher frequencies.

 

This is the Nvidia software for win7 64bit, its a little slow dl'ing from sager so this link might be faster if anyone wants it

Youre saying you flashed 2 D900f 280m to 285m successfully?

 

For his D900F, yes. But for the M570TU, no.

 

So youre saying it works for the d900f = MXM 3.0?.. its understandable it doesnt work for the M570TU since its a different card - MXM 2.1...
So what were you and Neil@Kobalt warning me about?

 

I don't know what Neil@Kobalt was trying to get through, but on my part I just wanted to see how far you would squirm to satisfy my hungry trollish stomach.

As for the MXM standard, they are simply not compatible with each other. http://forum.notebookreview.com/showpost.php?p=5873452&postcount=892

 

I was merely saying that I would advise against it, not that it won't work but the cards aren't identical to 280Ms.....

 

They look exactly the same.. and now that i got a look at the 285m bios (thanks again katiephil! ) i dont see any other difference than the clocks and obviously the device ids.. i admit im an average user at best and my knowledge is very limited, so if its not a secret can you explain what is actually the difference between these two (280m and 285m) - besides the above stated?

So would you say it would be safer to mod the 280m bios with the same clocks as the 285m and change the device id so the system recognises it as 285m or is it than the same if i just flash it with the actual 285m bios?

 

somebody mentioned here (forgot who and where) that the 285's memory timings where a bit more loose than on the 280. you should be able to see that on the "timings" tab in nibitor ... make sure to select the right timingset
so with the same memory freq you should have a tiny perfomance advantage on a 280's bios
i dont get why you try so hard pretending you had a 285? if you want to brag about the name, change the driver inf file.

 

Not to brag since i dont show my lappy to anyone or if someone does see it on my desk i dont tell that its actually a powerhouse (everyone thinks its an ancient box).. its just that i want to see if it can be done and the pleasure alone by doing it
And i checked the timings.. they are ExactlY the same as 280m.

See screenshots below; Left - 285m bios i got from katiephil (nibitor says 280m since i had to change id so it would even open the bios, since it doesnt support 285m yet) / Right - My 280m bios (never touched those timings)



Perhaps they meant the MXM 2.1 280m has different timings? Becouse unless this bios has been meddled with the timings are the same.

 

Yes that's right

Does not work on the M571TU as its a 2.1 GTX280M

Works on GTX280M 3.0 upgraded 2 D900F's to the new bios and they are still running fine without problems

and just done a W870CU GTX280M - GTX285M and that is still going strong without any crashes (2 hours now)

The bios for the 2.1 does have different memory timing and that's why it could not run at 1000MHz different DDR and GPU.

I think what Neil@Kobalt is trying to say is do this at your own risk .... ! If you get something wrong then your blind flashing the GPU back. Also not sure on how your warranty would stand, these are all points to consider

+ it's advisable to update your base units bios to the latest I was told by a friend Clevo can be a little funny if running old firmware and doing this update

 

The timings for the MXM 2.1 GTX 280M and the MXM 3.0 GTX 280M are the same. It is only the GTX 285M that has different timings for the highest level. http://forum.notebookreview.com/showpost.php?p=5867604&postcount=1119

There are a few other very small differences in the BIOS code, but like I mentioned in my post above, they are pretty much the same in terms of BIOS. Hardware wise, the GTX 285M is superior in quality.

 

The primary reason why the MXM 2.1 GTX 280M cannot overclock as high as it's MXM 3.0 counterpart is because the PCI-E socket cannot supply enough current or bandwidth to the card.

 

did you check that "timingset 0" is the active timingset? because of the 8 timingsets contained in the bios only one is used. if you cant find out which one you'll have to compare them all.

 

Thanks, now i think i have enough info on all of this..

 

Successfully flashed my 280m with the 285m bios (600/1500/1000 clocks,timings changed to those of 280m, left it at 1v). Gonna do some testing this weekend.

 

nice. i cant wait to see what you get.

 

3dmark06 crashed 2 times in a row today when i started testing so i flashed back to the 280m bios with clocks raised to those of 285m.. this works just fine, but the score is worse than the stock run i did when i got the laptop.. must be the damn driver.. i installed 195.62 before flashing and i had 186.81 when i got the laptop.. is it just me or is the new driver crappier..?

Stock clocks, 186.81 driver


Flashed to 285m clocks, 195.62 driver


Has anyone tested all the divers and can you tell me which one is the best performer (gaming performance being most important here, not synthetic)?

 

Everyone says 186.81 is the best. I prefer the 195.81
