They added 4GB of additional memory to the RTX 3060 8GB. You’ll never guess how much performance increases

A group of engineers from the channels Paulo Gomez and Hartek successfully modified the 8 GB version of the GeForce RTX 3060. In addition to adding the bones themselves, it was also necessary to make modifications to the memory bus, so that the card supports 192 bits. Test results from Unigine Superposition show that the modification gave the card a good performance.

Adding memory to the RTX 3060 8 GB card is not so easy

Graphics card modifications are quite a complex topic. Sometimes it takes a lot of knowledge and skills to improve a plant. We recently wrote about the successful operation of adding an additional 8 GB of memory to the GeForce RTX 3070. The modification resulted in a noticeable increase in the number of frames per second in games.

However, just adding modules wasn’t enough. It was also necessary to modify the resistors and flash the BIOS from the original 12GB version so that the card supported the 192-bit bus.

It just so happens that the same channel posted a new, similar video. This time, a slightly weaker NVIDIA model is captured against the background – GeForce RTX 3060 in the 8 GB version. Many of you probably know that the original version of the RTX 3060 had a reasonable 12GB of memory. Only later did a weaker variant appear, trimmed to 8GB of VRAM. However, low memory size is not everything. The newer model also provides a minimum memory bus of 128 bits, while the 12GB version works with a 192-bit bus.

The GeForce RTX 3060 8GB gains a lot after adding memory

Attempts to add memory to the GeForce RTX 3060 8 GB have been made by a group of technicians from Paulo Gomez and Hartek Channels. Most of these cards are based on boxes with up to 8 slots for memory chips. The version chosen for editing only had 4 occupied fields. However, just adding modules wasn’t enough. It was also necessary to modify the resistors and flash the BIOS from the original 12GB version so that the card supported the 192-bit bus.

To verify the differences in performance before and after modifications, the team tested the card twice on the Unigine Superposition benchmark with 1080p EXTREME settings. In either case, the card runs with the power limit set to 100% and at the same fan speed.

The difference is surprisingly large, at 22%. Of course, it should be borne in mind that we are talking about a benchmark, and not a real application, like a game. The latest OS shows us an increase in average frames by several frames per second. The biggest differences can be seen in the low 0.1%. The results show how much the card can lose at present due to the limitations of the amount of available memory and its bus.
