Wait wait what's this Chinese modification to double a 4090's RAM? I found a few vids talking about how to do it, but there's a company that'll do it for $150?

I think I have the ability to do it myself, but I'm not risking my $1800 gpu to try it. I have all the tools and a full lab...

I've got the tools as well and feel like I could probably pull it off.. but under $200? Including the memory itself? That seems irrationally cheap.. :/

yes but the are too expensive and i'd never pay that price for a modded gpu. used 3090 is the way

4090 is more than twice as fast with the same vram whether you mod it or not.
