AMD released its EPYC 4004 series Socket AM5 processors for small-business servers, which come in unique core and clock speed configurations not found on the client Ryzen series, such as 4-core/8-thread and the 28-lane PCIe Gen 5 I/O die. The EPYC 4124P is such a processor, and it turns out that the chip works on regular AM5 desktop motherboards, but with a special BIOS. Sergmann and Darkgregor built such contraptions, put it under liquid nitrogen cooling, and embarked on an overclocking adventure. They achieved a 6.70 GHz bench-stable all-core overclock, a huge upgrade from the 3.80 GHz base frequency. With this, the user was able to break many benchmark records for native quad-core processors (i.e. processors with 4 cores that aren't higher core-count chips with cores disabled in the BIOS).
