the Ryzen 7 5800X3D It’s not only the best processor for gaming today with the best price/FPS ratio on the market, but it also does so by having a feature that no one likes and that’s nothing more than capacity zero to overclock as such from AMD itself so he decided. The reasons the company exempts are questionable at best, and despite the fact that this block is already effective, some users have managed to evade it and have shown the results.
AMD Ryzen 7 5800X3D CPU Speed Crash
This 5800X3D is the world’s first processor with AMD’s so-called 3D V-Cache, which comes with almost the same features as its older and younger brother. We are talking about a Zen 3 7nm processor which will offer 8 cores and 16 threads at a base frequency of 3.4 GHz with a Boost at 4.5GHz and given the new technology implemented by its combined cache register, it switches to the 100 MBa round number that propels its performance to more than interesting levels if we take into account its price.
now take a motherboard with a suitable chipset and do 118 MHz BCLK.

It is Robert Hallock himself who has been responsible for giving the directives and explanations on the blocking that incorporates this processor in its frequency, which in no case can be modified. And it is that apparently and being the only Ryzen processor that does not allow overclocking to its credit, Hallock clarifies that this fact occurs for avoid physical damage to V-Cache 3D.
The reasons for this are complex and the explanations brief, since Hallock argues that although the arrays can sustain up to 1.6 volts, the 3D cache, being located above them, can only generate 1.35 volts and it therefore works at the limit of its possibilities in series. Therefore, allowing overclocking as such with its consequent voltage boost could lead to CPU death and therefore had to be speed locked for this Ryzen 7 5800X3D processor.
The jump to the restriction shows that the speed increase is possible
Makes the law makes the trap. since it has already been shown that it is possible to escape said block and even that downloading anything less than 300MHz This does not involve any risk, at least in the short term. Skatterbencher showed this CPU with a Boost for 4.822MHz modifying both the multiplier and its FCLK with a fairly restricted voltage of 1306 volts.
The method to escape what was imposed by AMD was to use the utility ASUS Voltage Suspend and logically it should be used at everyone’s risk, but it shows that in principle and for specific times more power can be extracted without risk from this CPU.
As expected, worse than average Ryzen 5000. I’m getting up to 2133 MHz with lots of WHEA errors. Up to 1900MHz is stable.

And it is that as expected, although the BIOS/UEFI will offer the same options as in any compatible Ryzen processor, these have no effect with the 5800X3D, since the multiplier does not go up or down and modify the FCLK implies that the base of the map no post and so we have to reset the BIOS to its default state.
Since this is a security measure for the physical integrity of the chip, we’re sure AMD won’t change its mind on this, but then it has a lot of work to do if the new Zen processors 4 finally come with 3D V -Cache on the market. Or will if it ends up like this they will come out with said block? In a few months, we will have the answer.
