YouTuber provides GeForce RTX 3070 video card with 16GB vram – Computer – Geeks

A modder has managed to provide an RTX 3070 video card with 16GB of vram. Before that, he replaced the eight memory chips of 1 GB with copies with a capacity of 2 GB. After various adjustments, the result was stable enough for a benchmark.

The craft work was done by the Russian YouTuber VIK. In his latest videos he takes a Palit GamingPro RTX 3070 in hand and doubles the amount of it. This was achieved by replacing the Samsung memory chips with ones with twice the capacity. Originally there are eight Gddr6 chips of 1GB on the card, with type number K4Z803256C-HC14. VIK replaced it with 2GB copies from the same manufacturer, with type number K4ZAF3258M-HC14.

Just soldering more memory on the pcb is not enough to get an RTX 3070 working with more vram. Software-related adjustments also need to be made. It is not possible to adjust the bios, but VIK found that it is possible to modify a certain strap setting adjust, which informs the bios of the available memory. Setting the value to 00110 resulted in the recognition of the larger memory modules.

After the adjustment, the card worked, but the GPU was not stable. Only when running two benchmarks at the same time was it possible to complete benchmarks. By clock locking Using EVGA’s Precision software, the RTX 3070 16GB managed to work stably. After that, VIK achieved a score of 13783 points in 3DMark Time Spy, which is roughly equal to what a regular RTX 3070 with 8GB vram achieves. In a second video, VIK discusses these problem solutions.

VIK already managed to create a RTX 2070 8GB upgradeable to 16GB vram, but that card wasn’t working stably enough to produce a benchmark result that actually comes close to what an RTX 2080 should achieve. The fact that the experiments are successful does mean that Nvidia has also come up with configurations of these video cards with 16GB vram. Last year there were rumors about the arrival of one RTX 3070 with 16GB and an RTX 3080 with 20GB. However, those versions were reportedly dropped before they were released.
