4090/4080 eDP DP_D vBIOS MOD

I made a vBIOS mod for RTX 4090/4080 based on the 4070 MXM card. There's a 99% chance it won't work due to falcon but who knows??

 

Anyways simply put, 4070 has eDP on DP_D whereas 4080/4090 has eDP on DP_B.

 

I simply modified the DCB table to match the 4070. 

 

WARNING: nvflashk will probably say invalid ROM. You will need to flash using SPI programmer.

Thanks.

 

But What, so their datasheets were right??? It said eDP on B I was like no way...

 

I have the datasheet of the RTX 4060 and it says eDP on D.

 

I don't have them with me right now.

 

X-Vsion answers about DP_D issue:

 

We encountered a factory with H610 motherboards that had this phenomenon, but later the BIOS PCIE was set to ASMP Disabled and they could be used 

 

MSI B760M-P open UEFI and CSM OK

 

Z690 no

 

Asrock B550 open UEFI and CSM OK

 

ASUS H610 Some models work, some models don't

 

I also sent them your Google drive link so they can test it and maybe... Find someone to certificate them?

I don't know who you are talking to , but might be useful to CC me on the email chain. The more information I have from them the easier it is to do mods

Jason from X-Vsion. Helen doesn't answer to emails anymore. Jason gave me more informations than Helen did in a 1 year...

Jason from X-Vsion told me something interesting.

 

Their early version of the 4080 and 4090 (black PCB with some capacitors on the X-bracket way) have full eDP support on D. It used some Clevo VBIOS that I can't find.

 

@janepahas the Black PCB version.

@ssj92

Got it https://drive.google.com/file/d/1Xt0R8L33k5xgRKVUs2Kbt54Da6Ra5Kf_/view?usp=drivesdk

 

This is the early version of the 4090 VBIOS. 

 

Could you tell us if the DCB is different than the latest 4090 VBIOS? VBIOS version number? Can't check because I have no computers there, can only be available in 4-5 days 😞Thanks
