The well-known overclocking team TecLab recently challenged the hardware limits again and successfully cracked the software protection mechanism of the GeForce RTX 50 series graphics cards, pushing the GDDR7 memory frequency to the level of the next-generation chip that has not yet been officially released. This breakthrough achievement demonstrates the huge overclocking potential of the Blackwell architecture.
The TecLab team used a Galax RTX 5070 Ti 1-Click OC graphics card and used professional overclocking tools to increase the memory frequency by 3000MHz based on the baseline. To achieve this goal, they adopted a dual cracking strategy.
First, the team bypassed the TDP limitation at the hardware level by shunting the sensing resistor. More importantly, they logically outsmarted the frequency management system by tricking the graphics card into "thinking" it was running in a default or slightly overclocked state, thereby preventing the internal security mechanism from being activated.
After cracking, the graphics card memory frequency reached an astonishing 18,000MHz, and the equivalent transmission speed was as high as 36Gbps - this level is exactly the next-generation GDDR7 module specification that memory manufacturers such as Samsung and Micron are preparing to launch. At present, these high-speed memory modules are not yet available on the market, and it is optimistically estimated that they will not be available until the end of this year, provided that the production capacity shortage problem is resolved.
TecLab not only pursues digital breakthroughs, but also verifies actual performance improvements. On the Unigine Superposition benchmark:
· Default frequency: 9,922 minutes
· Regular overclocking (core and graphics within standard range): 11,722 points
· Overclocked after cracking (video memory up to 36Gbps): 11,993 points
This means that the average player cannot achieve this level of performance by simply dragging the slider through MSI Afterburner. However, the existing 28Gbps graphics memory chip can stably run on the future 36Gbps module specifications, fully demonstrating the potential of the RTX 50 series graphics cards.
The TecLab team has hinted that this is far from the limit. Their next test object will be the more high-end GALAX RTX 5070 Ti HOF - this graphics card is famous for its factory-tuned extreme overclocking potential and is designed for extreme overclocking players.
As the memory frequency block is cracked, the overclocking space of the RTX 50 series will be further released. For gamers and overclocking enthusiasts who pursue the ultimate in performance, the potential of the Blackwell architecture has just begun to unfold.
