GDDR7 Overclocking Tool Unlocks 1248 GB/s Bandwidth on RTX 5060 Ti
A new memory overclocking tool named 'mlock' allows users to bypass stock limitations on GDDR7 memory, enabling an RTX 5060 Ti GPU to reach 1248 GB/s in memory bandwidth with a +5500 MHz overclock. This achievement represents a 40% increase over standard memory bandwidth. Local LLM inference performance, especially token generation during decoding, is primarily bound by memory bandwidth rather than GPU compute power. Unlocking a 40% increase in bandwidth significantly speeds up token generation for open-source AI models running on consumer hardware. The significant frequency headroom achieved with mlock suggests that early GDDR7 modules are conservative in their stock clock configurations. However, running a extreme +5500 MHz memory offset increases thermal output and power consumption, raising potential stability and long-term hardware reliability concerns.
## BACKGROUND
Modern graphics cards utilize high-speed video RAM (VRAM) standard graphics memory, such as GDDR7, to feed data to compute units. When serving Large Language Models (LLMs) locally, the entire architecture must repeatedly reload model weights from VRAM for every single generated token. As a result, memory bandwidth serves as the primary bottleneck determining token generation speeds.
