Yes, I've received the 4090 from ZRT. I have been very busy at work and didn't get to testing it out yet. Don't bother trying to get the ZRT 4090 from Taobao. All the sellers use the ZRT pictures but sell you an X-Vsion card and try to sprout nonsense saying that they are the same thing. I just went through one such case and went through great efforts to get the card refunded. So i directly contacted ZRT and got the card from them instead. Price wise, the difference between Taobao's supposed ZRT 4090 and the actual card from ZRT is not much. However, you get the full warranty and technical support directly from ZRT. If you want, I can share with you via PM the sales manager's contact details. You can reach out to her to sort things out.

Just sorted out the purchase of a 4090 directly with ZRT. It should arrive either end of next week or early the following week. I will test it in the LVDS M6800 while i await for my eDP M6800 and associated parts to arrive.

Ok, the 4090 mobile card that I got does indeed look like a ZRT not look like a ZRT and is instead a X-Vsion card. I've used the CH341 bios programmer to download a copy of the vbios for @SuperMG and he has confirmed from the vbios extract as well. Work meeting ended a bit late. I will install the card tomorrow and test it with the Optimus M6800. I am no longer testing the card in the LVDS M6800 as I was also intending to deploy it in a eDP M6800 which is now not possible without the EDID hack. I have initiated for a full refund and return of the card with Taobao. Unless the seller really confirms that he has a ZRT version with proper pictures and video to backup his claim, if not I'm not getting the 4090 from him anymore. I will instead deploy the P5200 to the eDP M6800 I am building. @SuperMG the P5200 will work with the eDP M6800 right? *Edit: On closer look, it is an X-Vsion 4090 MXM card and not a ZRT version. It is going against the confirmation by the seller and I have initiated for a full refund.*

I will keep searching eBay from now on! @Annihilator What's the key search words that you used?

Of course. Why wouldn't it work?

You lucky man. They are extremely rare these days.

Where did you get the 2133 rams?

@SuperMG @Annihilator @Aaron44126 What's the fastest mxm card we can deploy in a M6800 LVDS setup without the mux limiting the performance of the mxm card? P5200? RTX5000? Or?

That sucks... But we don't really need the volume control we do need the LED board to see the status.

It looks like we have a winner here! I need to wait for the eBay seller to make the same heatsink setup for me!

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.

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!

I just dived in and bought an NVIDIA GeForce RTX 4090 Laptop GPU from a seller in Taobao and he is working together with me to try to get it working on the M6800. He seems fairly knowledgeable as well. I should get it in a few days' time and see how it works out. However, I need to make sure the new GPU heatsink that I got from eBay is the newer version that works with the M6800 unlike the older version that SuperMG got from the same seller. If it works, I will have a few cards to sell... P5000 for the M6800 and a P5200 which I have yet to flash with the vbios that works with the M6800 and an RTX3000.

Very nice indeed!

You got the 4 heatpipes version + a new CPU heatsink from the same seller as the 3 heatpipes? If that's the case, then I need to reach out to him.
