Precision M6800 questions and upgrades

[DynamiteZerg]

I'm uploading the images I got from the seller. Not sure what brand this is but it is a 150W card. I will ask the seller the manufacturer's name and take clearer pictures.

 

Where are you selling the cable mod? @SuperMG

 

Update: Seller just confirmed it is made by ZRT! So now we can get the vbios!

IT'S ZRT OMG. Please GET THE VBIOSES!! I want to flash on 4080 and 4090 so we can avoid the EDID override method!!

 

Same design as ZRT 100%, not x-vsion, the BIOS chip is in a different place

Looks like we have a winner on our hands! I'll ask the seller if he can help to extract the vbios from the card first and shared it with me.

The seller needs to use GPU-Z and extract from there. He can do it for the 4080 too. It'll generate a download link from techpowerup

 

Because ZRT and other people ignored me for 5 months. I've been trying to get their VBIOSes for 5 months... I just hope the images you got are indeed the right GPU and not the x-vsion one.

 

Do you have the VBIOS version number or a GPU-Z screenshot?

 

For myself I need the 4080 150W VBIOS and 4090 150W VBIOS. But if the seller could dump 135W Max-Q versions why not, everyone will be happy.

DIY for Dell Precision M6800 GPU heatsink | eBay

This is the better version if you're planning to use 150W cards (with PTM7950) + better designed CPU heatsink like the Alienware 17 R1 Ranger design, so better overclocking for the CPU right?

 

Mine will arrive this week, maybe on Friday? It means I'll have a spare "130W" 3 heatpipes that has one badly curved heatpipe. If someone wants it, I can list it for 45€ and then you can modify the heatpipes if you want.

 

@DynamiteZergI sell them on ebay. This is version 1. It allows backlight enable and makes the internal display work again. The newer RTX cards don't have the backlight pins connected from the core.
