Copper Plate Mod Lowers RTX 3080 GDDR6X Memory Temps by 25 Degrees C
A copper plate used in the video was designed by CoolMyGPU for specific RTX 3080 AIB partner cards. Other copper memory cooling plates for the RTX 3080/Ti, RTX 3090, RTX 3060/Ti, and RTX 3070/Ti are available. It includes both Founders Edition plates and third-party designs.
The video shows a copper memory cooling plate for an MSI Ventus RTX 3080 graphics card. Remove the graphics card's native cooler first. Then, remove any thermal pads and thermal paste that are cooling the GDDR6X and main GPU core, as well as any thermal pad residue. The copper cooling plate and GPU heatsink are installed after a test fit. The GPU's cooling technology maintains the plate in place without the need for additional screws.
Dandy's RTX 3080 Ventus graphics card's copper plate decreased memory temperatures by 20%, down from 94C to barely 75C in mining activities and substantially lower in games. GDDR6X temperatures should not surpass 100C in our testing of Nvidia's best RTX 30-series cards, including AIB partner versions, to avoid thermal throttling. If the temperature of your GPU's memory hits 110 degrees Celsius or above, the graphics card will limit clock rates and stronger cooling will be required. Gaming workloads are often less demanding than mining workloads, but we've seen GPUs (such as the RTX 3080 Ti Founders Edition) reach 104 degrees Celsius on a regular basis. In a mining role, 110C is found on a number of GDDR6X cards, including nearly all Founders Edition cards (with the exception of the RTX 3070 Ti, which only has 8GB VRAM). Only a few AIB partner cards with improved memory cooling fall below that mark.
Problems for production GPUs and motherboards: high copper prices - 10/01/2021 09:52 AM
According to Digitimes (paywall, via Tom's Hardware), skyrocketing copper prices are the next big challenge for the graphics card and motherboard manufacturing industries. ...

If that copper plate really works so well, the design might get copied by card manufacturers, unless CoolMyGPU has managed to patent it. It's hard to say from the photo, but if that plate is of uniform thickness and not machined, some Chinese factory should be able to laser cut thousands of them in a day. I don't think the price would be many dollars a piece. Maybe there are some other complications in using them. Only people with lots of experience with custom cooling graphics cards would know.

backplate usually raises the temp, by experience
The problem I have with my 3090 is the VRAM on the top of the card hitting it's max temp. The backplate just doesn't cool it well enough.

AIBs should have known about copper plate, just that these copper plate don't allow for any margin of error that thermal pad do. A lot of things can go wrong if the copper shim is slightly thicker than it should be, like crushed BGA on VRAM or poor thermal contact between die and cooler.

It's not hard to copy for AIBs, just costs more because they have to mill out more material to make the raised surfaces for the memory.
Thermal Pads are cheaper, which is why this is never gonna see the light of day out of the box.
And as mentioned in the post above, everything has to be perfect.
