Precision M6800 questions and upgrades

[Aaron44126]

Just saw another post with someone running a Pascal GPU in the M6600. Maybe this problem is only with Kepler and Maxwell GPUs.

 

(Actually don’t remember what exactly happens with Maxwell but I want to say it won’t boot.)

Is the laptop booting up fine though? Or it doesn’t even post with nvidia card? 
 

I have some ideas if it at least posts

you could try tinker the vbios like that person did with his quadro p5200 if your vbios chip cant be attach with CH341A, i think they call the section what i seen in a redit post talks of what started to get the quadro 5200 working is the header?, like anything before offset line 00000A00. i recently messed around p106m vbios by replace the header with the working vbios of quadro p4000  and it allow me to boot without me switching out the gpu just enable back optimus and  back in the p106m, but the same story on p4000 on m6600 but is unusable, it shows on device manager with yellow exclamation mark with the drivers installed and powertech read clock speed zero. possibly some where in the header to allow optimus  to work on m6600? i also have theroy of maxwell gpus of tesla m6 and the vbios of m3000m i posted both hold key to allow optimus to work on m6600 for tesla m6 with m3000m vbios as it has no header but the code is different vs other m3000m vbios and the header of m6 like as i try m6 on my m6600 it booted to windows even tho optimus doesnt plus the trick i did with p106m, may allow the maxwell gpu to boot into windows without it freezing. i seen certain models of gtx 980m on ebay  that you could attach CH341A making flashing easier to unbrick gpus when you mess something up.

Do you have a link to the reddit thread on this vBIOS mod? I have 880M 980M RTX 3000 GPUs so I have a few generations I can play with.

did but now is completely gone but lucky i archive as pdf, this is what he said how he did it and the files he posted on this post. if the date is correct of the pdf this is 2 months after he went ask in macrumors.

Wow thanks for this. I will study it later and see what he did. Maybe this could also help us solve the 900 series working on M18xR1 as well. 

 

They all seem to be BIOS/vBIOS issues during Dell's Sandy Bridge laptops. 

 

Any chance you got his info? Looks like his reddit account is deleted.
