Overclocker Exceeds 5 GHz on AMD's Ryzen 7 5800X3D
MSI team overclocker TSAIK has successfully clocked AMD's Ryzen 7 5800X3D CPU above the critical 5 GHz mark. Interesting for a PU with a locked miltiplier.
TSAIK's AMD Ryzen 7 5800X3D CPU-Z verified clock speed achievement was 5.14178 GHz. Comfortably above 5 GHz, the achievement is also a significant step up from yesterday's HWBot confirmed world record; ScatterBencher, AKA Massman's 4.74 GHz overclock. We can observe that TSAIK used a 113 MHz BCLK and a 1.20V core voltage.
BCLK overclocking can generate "RTC Bugs," and system stability can suffer if the BCLK is pushed beyond the anticipated value of 100 MHz. Given the disadvantages of BCLK overclocking, this could be why TSAIK, who has a sizable presence on HWBot, has not yet uploaded this AMD Ryzen 7 5800X3D clock speed to the site and has done little more with it than run CPU-Z validator.
As a member of the MSI team, TSAIK gets access to the company's greatest components, and the motherboard responsible for the 5.14 GHz overclock was the enticing MSI MEG X570 Godlike. Although the motherboard was running the 1.G5T2 BIOS (AGESA 1.2.0.6 Patch C), MSI may have permitted some under-the-radar BIOS adjustments that increased the Ryzen 7 5800X3D's overclocking capabilities for its in-house OC expert.

Now I really wish AMD hadn't locked the multiplier on it, even if the voltage is locked. There's already conspiracy theories going around that AMD did it so it wouldn't be close in performance to Zen 4.
There's no way for a motherboard without an external clock generator to get a base clock overclock, is there?
Too hot when even overclocked a few hundred Mhz on water.

It looks a bit like the extra cache sabotages the heat transfer somewhat, because there is a extra layer on top of the chip, so it acts a bit like the Intel delid years.
Stock performance is fine, but extra heat from overclocking is hitting the chip harder, then it would a 5800x, because the heat does not flow as easily away from the hot spots.

It would have been preferable if AMD had locked voltage, EDC, PPT and TDC. Instead of the multiplier.
This would allow a decent control on the chips temperatures, while allowing a decent margin for OC.

If this was a 5800x and could do 5.15 on 1.2v i would not consider it even a golden sample..
Or platinum or diamond sample ... Maybe mythril sample :p
