NVIDIA GeForce RTX 3060 8GB modded to 12GB: gets 22% perf increase

NVIDIA GeForce RTX 3060 8GB modded to 12GB: gets 22% perf increase
May 02, 2023

NVIDIA originally launched the GeForce RTX 3060 with 12GB of GDDR6 memory... and then not too long ago in 8GB form.

But PC modders have just changed that.

A new video from Paulo Gomes and "harteck" has been released, taking the regular GeForce RTX 3060 8GB and strapping 12GB to it... the results? Not too bad, actually. There is a difference here that should be noted:

  • Original GeForce RTX 3060 12GB -- 192-bit memory bus
  • Updated GeForce RTX 3060 8GB -- 128-bit memory bus

We wouldn't recommend anyone do this to their GeForce RTX 3060 8GB, but it can be modded back to its original 12GB memory if it's done right. Most of the current RTX 3060 8GB cards still use the original PCB design, which is capable of hosting up to 8 memory modules, but the RTX 3060 8GB used in this test only had 4 memory modules used... leaving room for the mod.

Modding the RTX 3060 from 8GB to 12GB of memory isn't the only thing required, as the 12GB model has a 192-bit memory bus and the 8GB model has a slower 128-bit memory bus. But... the card can be tricked into supporting the higher-end 192-bit memory bus by changing over resistors, and with a BIOS replacement from the original 12GB model.

After the modders transplanted the increased 12GB of GDDR6 memory onto the RTX 3060 8GB card, the card was tested in some benchmarks with some interesting results. First off, we have the Unigine Superposition benchmark with a 100% power limit set, and the same fan speed across both cards... in the end, a very respectable 22% higher score on the 1080p Extreme profile. The results went from 4235 to 5196... not bad at all, but I really want to see some games tested like this.
