Clearly, Ryzen 7000X3D are not made for overclocking… Even if some some manage to do it successfully the approach is clearly more risky than on the Ryzen 7000X. The reason behind this? The 3D V-Cache memory which is a serious brake to the increase of frequencies. Besides, a little too much VDDCR and the whole configuration goes up in smoke.
Ryzen 7000X3D: don’t push the VDDCR too much!
When overclocking, the problem with this series of CPUs comes from the additional 3D V-Cache memory positioned above the CCD(Core Complex Die). It is this positioning that causes problems since the gap between the cache and the cores is filled by silicon. Increasing the voltage of one of these CPUs leads to an increase in power consumption and temperature, at least to a greater extent than a Ryzen without 3D V-Cache.
Igor’s Lab has identified six pins that can cause problems. They are located under the CCD at the 3D V-Cache memory. If you turn up the frequencies a bit too much, poof, the CPU and motherboard can go up in smoke due to too high a temperature at this level. Yes, stacking a lot of things causes a resistance effect that generates more heat.
Unfortunately, AMD’s thermal and electrical protection mechanisms are not enough in this scenario to protect the hardware. As you can see above, the pins on the socket have blackened, while the CPU PCB has become downright deformed. In short, it’s not pretty.
