Nvidia has never seen fit to release a clone of its previous generation GeForce RTX 2070 With 16GB of video memory, though, leaked blueprints suggest it was possible and planned at some point. To prove the first, someone took matters into their own hands and carefully modified the GeForce RTX 2070 with twice the memory.
The aforementioned scheme was what drove the moder, to pass “VIC-on” on it YouTube channel (Across Tom’s devices), To try to put the exact memory doubling. Even better, he posted a video for the full mode, which was included above.
The card is shipped with an 8GB GDDR6 memory made by Micron. However, the schematic indicates that the GeForce RTX 2070 also supports both 1GB and 2GB of Samsung GDDR6 memory chips. Armed with this information, VIC-on tracked down a package of eight Samsung 2GB GDDR6 memory chips on Aliexpress, paying just over $ 200.
This is an expensive upgrade, but a model like this extends beyond practicality and falls squarely in the proof-of-concept territory. It’s definitely not the same as upgrading the RAM in a desktop computer or laptop. Instead of just ripping out any modules, the VIC-on had to use a heat gun to loosen the physical memory chips surrounding the GPU, and eject them with tweezers.
Before installing the upgraded 2GB Samsung chips he bought, VIC-on had to move a bunch of resistors onto the back side of the PCB. This means breaking the soldering iron. Then he put the Samsung chips in place, turned on his computer with the modified card installed, and supposedly skipped his fingers off the camera.
It booted into Windows without a problem. And when it launched GPU-Z, the tool recognized 16GB of Samsung GDDR6 memory. So far, so good. Unfortunately, sailing wasn’t smooth from there.
Test your modified card with FurMark, a tool that squeezes graphics cards. It seems to be working fine, but after exiting the computer crashes to a black screen. VIC-on notes that this occurs after any kind of load is placed on the card, including gameplay.
There are many reasons why this might happen. However, he suspects the culprit is the BIOS. Specifically, VIC-on imagines the card to go up because the frequency and voltage table in the BIOS doesn’t match what is now installed.
Regardless, VIC-on deserves a major pillar for doing what Nvidia has never done, which is double the memory found on the GeForce RTX 2070. up to the current generation GeForce RTX 3070 It only has 8GB of GDDR6 memory, and he ultimately intends to modify one of those as well.
