I really dont get it.
I flashed ROM from namgorf and confirmed that it has InfoROM
Still having this screen on Dell R720
I updated latest firmware on R720 as well...
It works fine on HP Z420 but not on Dell R720
What am I missing

Did you ever get past this? You could say I am following in your footsteps from the shadows. I just converted a Tesla K10 into an NVIDIA GRID K2 yesterday and I get the same result on my PowerEdge R720.
I soldered the strap resistors, reassembled the card with new thermal paste, and flashed the "2014" BIOS to each GPU. I did notice the "PLX" entry in nvflash but didn't do anything with that. Was I supposed to? The SHA256 hash of the BIOS file I flashed was BB04DF8552BF60B827E1C963B1D8527386D9448D554BC01799CE7F8605763951
My R720 has dual E5-2650 V2s, 128GB of PC3L-12800R, and dual 750W power supplies. I saw the other post here about power delivery, but this card has a max power consumption at full load of maybe 200W, and my system power readout is only sitting at 280W with this GPU installed. I am using a quick and dirty homemade power cable. Please excuse the WAGO Lever Nuts. I triple-checked the pinout and continuity with a multimeter, for what it's worth.
Right now I am using the riser connected to CPU2, because it was easier to install the card over there. I ran out of time for troubleshooting last night. I did not try the other riser, removing all other PCI-e cards, or enabling "Above 4G decoding" in the BIOS yet. That is on the agenda for tonight.
I am running a BIOS version from 2016 to avoid the Spectre/Meltdown microcode mitigation.
Hello,
an another solution to try if it's works , take an PC Desktop in windows 10 , put the real power VGA cable ( One 8 pins and One 6 pins ) , of course keep a video card ( so you need 2 * 16X PCI E ) .
If windows detect Grid K2, ( first good point)
launch "GPU Z" software, choose the card 1 or 2, and make a backup of the Bios.
Compare the bios with K2 bios ( with no error it's the second good point )
Use KeplerBiosTweaker_1.27
and you can optimise the consumation of the card and putin the modfied bios in your 2 cards
I make a image of what i need to change in the K10 to change it in Grid K2, could you confirme its ok please?
Hi Modders,
first off, thank you very much for sharing this awsome knowledge -
.. got myself a gt640 wich will undergo some resistor soldering soon.
I am writing this post to ask, if anybody knows if the Tesla K40 is modabble in a similar way ?
I think its the same PCB like a Quatto 6000, is that correct ?
Could it be modded into a K2 or any other Card for that matter ?
I would like to use it in the VMware Host with the "vCPU" Feature.
Looking forward to get some insights from the experts.
Thanks !

I am still having same issue.
I tried multiple K2 BIOS but the issue is still there.
I also tried DELL K2 bios updater but didnt fix the problem (https://www.dell.com/support/home/uk/en/ukbsdt1/drivers/driversdetails?driverid=598p8)
I found inforom from CISCO iso but it didnt really help.
I also suspected my RISER cable which was 9H6FV but wiring is correct and it provided 12V/GND in proper pins (tested with multi meter)
I googled alot and no one complained about compatability issue other than you and me.
Also saw few people uses K2 in R720 without any issue.
At this point, there are only three things left.
1. Requires 1100W
2. Proper inforom
3. 40k ohm is wrong.
Since K2 is working fine on other system, I think its gonna be either option 1 or option 2.

I just ordered 2x 1100W power supploy for R720 and will arrive end of next week.
This will eliminate one of possibility.
I will update the thread once I test it.
