News Defective RTX 3070 gets 12GB VRAM upgrade — mod boosts performance by 66% in RE4

[Admin]

A Repair technician and his team successfully swapped the 8GB VRAM on an RTX 3070 with one defective memory channel to recognize and use 12GB GDDR6 memory, showing a good performance yield as a result

66%... vs. a GPU with one memory die disabled to leave it with 6GB accessible, rather than against a stock 3070 with the full bus width and 8GB available.

It should also be noted that the RTX 3070 has a limited 192-bit memory bus. Hence, he found a middle ground by modding it into an RTX 3070 12GB.

No. The original RTX 3070 sports a 256-bit memory bus width. After modding, it reduced to 192-bit.

The team ran the Resident Evil 4 benchmark on this RTX 3070 high image quality setting and a 546.17 WHQL driver to demonstrate its performance. This graphics setting demands more RAM, showing it needs at least 13.81 GB. During this testing, it used the required memory from the system's RAM. Ultimately, the RTX 3070 with a 6GB GDDR6 VRAM yielded 40 to 50 FPS.

Excuse me, what ? That setting is VRAM, and not system RAM. The game is requiring 14GB graphics memory/VRAM as a minimum as shown in the game's settings, 13.81GB to be precise.

Earlier with 6GB VRAM frame buffer the game had to resort to the system memory, since 6GB was insufficient. But after modding, there was 11GB of VRAM available on the card for this game to utilize, since RE4 is a very VRAM-hungry game.

RE4 title requires more VRAM, not system RAM. Please make the necessary correction.

So you get more vram but with less bus width and bandwidth after modding, lol 😂 still crippled

The 192 bit mistake should be corrected but there's nothing wrong with referring to VRAM as RAM...

Sure there is. Precise descriptions are better than ambiguous ones.

Nope. Both system memory and graphics memory are entirely different things and both behave differently on how an app or game uses them in any system.

Referring them as same would be a blunder
