When NVIDIA’s GeForce RTX 30 series graphics cards equipped with GDDR6X
memory are running, the heat generated by the memory is not small, which is more obvious on the high-end GeForce RTX 3080/3090 series. In order to solve the heat dissipation problem of the video memory, some enthusiasts will modify it and add copper spacers to the video memory to improve the heat dissipation efficiency. Similar modifications have been made in the past, but as the graphics card heats up more and more, it has attracted people’s attention again.
Recently, the Youtube channel DandyWorks
demonstrated the use of CoolMyGPU
customized copper modules, which were replaced on GeForce RTX 3080. In addition to the GeForce RTX 3080, there are custom copper modules including other GeForce RTX 30 series, and the manufacturer even offers copper modules designed for the GeForce RTX 3090 memory. It should be reminded that this replacement operation has certain risks and will void the warranty of the graphics card.
The effect of the replacement is very obvious, and the GPU/memory temperature has dropped:
- Cyberpunk 2077: temperature downs from 78°C/88°C to 75°C/70°C
- Ethereum mining: temperature downs from 65°C/94°C to 58°C/75°C
- OctaneBench: temperature downs from 78°C/92°C to 78°C/76°C
Although it is only a copper module for graphics memory cooling, it will affect the cooling effect of the entire graphics card. Normally, the temperature of GDDR6X video memory is best controlled at 100°C or below. Normally, graphics card manufacturers will take this into account when designing heatsinks. GDDR6X memory is generally fine even if it runs above 105°C, but if it runs at 110°C or above for a long time, it is best to limit the clock and consider replacing the cooling module.
