Modder doubles GeForce RTX 3070 memory from 8GB to 16 GB GDDR6

It's certainly not the first time that we see a modder altering the GDDR6 DRAM amount on a graphics card, and there you have it, GeForce RTX 3070 modded to 16 GB GDDR6.

This Geforce RTX 3070is equipped with 8 GB as standard. That may be enough for most cases at the moment, but it is not totally future-proof and anyone who is in the enthusiast area would agree, 16 GB is better. The SMT soldered Samsung modules type K4Z803256C-HC14 can be exchanged for modules of type K4ZAF3258M-HC14. They are almost identical with the subtle difference that the capacity is doubled from 1 Gbit to 2 Gbit. After a bit of fiddling with even the card recognized the new 16GB partition. Unfortunately, it really needs a BIOS mod with proper timings, voltages and frequency to become a proper success. And that last bit is getting more complicated.

It didn't work 100%; software like 3D Mark, Furmark and Crypto mining ran without restrictions, but the card did not render 3D graphics problem free. Here and there it created generated black screens. Further tests showed it is clock frequency-related.

I was thinking: either Chinese or Russian modder.
Has to be. Why?
Close resources available and tools. And the guts.

As the modder said it is not really an issue of BIOS but rather a driver issue. His conspiracy theory was that it is done intentionally by Nvidia so that AIBs could not release some custom cards with more RAM than Nividia has allowed. His hopes was that with the release of RTX 3070 (which supposedly will have 16GB VRAM) the modded card will also work flawlessly.

He is Russian.

@ruukjis the aibs for sure can design and release a 16gb card . But if they do with out nvidia's permission ....i do not think they will keep releasing nvidia cards for long :p

LOL thats stupid thinking from someone smart enough to make 16GB mod. I mean they don't even have to put it into contract, Green Light program whatever.
All NV has to do is tell AIBs: pls don't do it, OR ELSE.
