AMD’s first V-cache processor will be launched soon, but users have already been able to get their hands on copies. Although the chip is not officially overclockable, some have still managed to circumvent the limitations put in place by AMD.
The 5800X3D is the first processor to include 3D V-cache technology, which promises to massively improve performance in gaming workloads. Nevertheless, although this technology can give a real boost to in-game performance, AMD had to sacrifice some key features such as overclocking support.
Indeed, in an interview, AMD Technical Marketing Manager Robert Hallock claimed that AMD had safeguards in place to prevent users from overclocking the chip. The 3D V-Cache technology seems to make the chip very fragile due to the lower battery voltage of 1.35V, compared to 1.5-1.6V for a typical CPU, that’s why any overclocking could seriously damage the Ryzen 7 5800X3D. However, some users have already managed to circumvent AMD’s limitations and overclock the chip beyond the theoretical maximum limit.
It overclocks its Ryzen 7 5800X3D beyond 4.5 GHz
The Ryzen 7 5800X3D is a processor that offers 8 cores, 16 threads and 100MB of cache combined thanks to its additional 64MB of 3D Stacked SRAM design. AMD went so far as to state at CES 2022 that the 5800X3D was faster than the 5900X and 12900K in certain workloads. It seems they underestimated the new chip as it outperforms Intel’s new flagship, the 12900KS, in early benchmarks.
Frequencies are maintained at 3.4 GHz in base and 4.5 GHz in boost with a TDP of 105 W. While it’s not normally possible to go further in frequencies, a user named @SkatterBencher on Twitter posted a screenshot of the processor running at a frequency of 4.82 GHz.
For this, the overclocker would have used an ASUS ROG Crossair VII Extreme motherboard with a voltage of 1.306V, a multiplier of 45.5 and a BCLK of 105.99 MH. He has yet to explain exactly how he managed to get around the limitations, but is expected to share a video detailing the procedure soon. We hope that AMD will not take the opportunity to correct the flaw.
