It has not been released yet and the protection or blockade that AMD imposed on its best gaming processor within the Ryzen range has already fallen: the 5800X3D. The company’s technical reasons for disabling its overclocking are somewhat questionable and more so from what we are going to see, but at the same time they collide head-on with the policies they have implemented. What have they achieved? And above all, how have they done it to skip the speed lock on the AMD Ryzen 7 5800X3D processor?
The Ryzen 7 5800X3D is not only the best gaming processor today with the best price/FPS ratio on the market, but it also does so by having a feature that no one likes and it is nothing more than the null capacity of overclocking as such. that AMD itself has decided so. The reasons that the company exempts are questionable at best, and despite the fact that this block is already effective, certain users have managed to evade it and have shown the results.
Blocking the speed of the AMD Ryzen 7 5800X3D processor
This 5800X3D is the first processor in the world with the so-called 3D V-Cache from AMD, which comes with almost the same features as its older and younger brother. We are talking about a 7nm Zen 3 CPU that will offer 8 cores and 16 threads at a base frequency of 3.4 GHz with a Boost at 4.5 GHz and given the new technology that implements its combined cache register it goes up to 100 MB , a round figure that boosts its performance to more than interesting levels if we take into account its price.
now grab a motherboard with a proper chipset and do 118MHz BCLK.

It has been Robert Hallock himself who has been in charge of giving the guidelines and explanations about the blocking that integrates this processor in its frequency, which cannot be modified in any way. And it is that apparently and being the only Ryzen CPU that does not allow overclocking to his credit, Hallock specifies that this fact occurs to avoid physical damage to the 3D V-Cache .
The reasons for this are complex and the explanations brief, since Hallock argues that although the dies can withstand up to 1.6 volts, the 3D cache, being located on top of them, can only generate 1.35 volts and is therefore working at the limit of its possibilities. serial. Therefore, allowing overclocking as such with its consequent increase in voltage could lead to the death of the CPU and therefore a block has had to be put on the speed of this Ryzen 7 5800X3D processor.
The jump to the restriction shows that the speed increase is possible
Done the law done the snare. since it has already been shown that avoiding said block is possible and even that going up to no less than 300 MHz does not imply any risk, at least in the short term. Skatterbencher have shown this CPU with a Boost at 4,822 MHz by modifying both the multiplier and its FCLK with a fairly restrained voltage of 1,306 volts .
The method to evade what was imposed by AMD has been to use the ASUS Voltage Suspension utility and logically it should be used at the risk of each one, but it shows that in principle and for specific moments more power can be extracted without risk from this CPU.
As expected, worse than average Ryzen 5000. I get up to 2133MHz with many 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 modifying the FCLK implies that the board non-POST base and therefore we have to reset the BIOS to its default state.
As it is a security measure for the physical integrity of the chip, we are sure that AMD is not going to change its mind about it, but then it has a lot of work to do if the new Zen 4 processors finally arrive with 3D V-Cache on the market. Or is it that if this ends up being like this they will come out with said block? In a few months we will have the answer.
