NVIDIA GeForce GTX 590 Maximum Overclocking Results Linus Tech Tips

Linus Tech Tips investigates how far a GTX 590 can be pushed beyond stock speeds using advanced overclocking. The host starts by testing the latest Afterburner beta that supports overvolting and carefully evaluates whether the underclocked GF11 configuration on the GTX 590 can approach the performance of a single GTX 580 when voltage is increased. He explains that although the hardware cannot match single-card performance at the same voltage, he manages to push the core clock well beyond stock, hitting approximately 809 MHz with a shader/clocks aligned to the higher end, and memory clocks exceeding 2.1 GHz. The host notes that this comes with dramatically higher power draw and heat, and he explicitly warns viewers about potential warranty implications and long-term reliability. He then shares the final benchmarking results, using 3DMark 11 with an extreme overclock and later comparing to stock results, highlighting a marked but variable performance uplift across applications. The temperatures stay high, with peaks around the upper 80s Celsius and power consumption reaching over 500 watts from the wall, sometimes approaching 550 to 570 watts in demanding games like Metro 2033. Across tests, the overclocked GTX 590 demonstrates notable performance gains in some scenarios, with the author reporting up to roughly 15 percent improvements in certain workloads, and he emphasizes the practical realities of heat, noise, and power when chasing higher clocks. In closing, Linus thanks viewers for watching, suggests further experiments with cooling and firmware modifications, and invites audiences to subscribe for more hardware reviews and overclocking content, while reiterating the experimental and warranty-related caveats of pushing a GPU beyond stock specifications.
