AMD Ryzen 7 5800X3D ‘locked’ overclocked to 5.14GHz

For a supposedly “locked” chip, the AMD Ryzen 7 5800X3D seems to spend a lot of time since launch being overclocked. The latest comes from MSI’s in-house overclocker, TSAIK, which managed to push the chip to 5.14 GHz using the MSI X570 Godlike motherboard. And it’s this $699 motherboard that seems to be the key to the latest and most impressive overclock.

In case you missed it, AMD’s Ryzen 7 5800X3D was released last week and it’s an intriguing CPU. While not a purchase recommendation for most gamers, the underlying 3D V-Cache technology is exciting and promises good things for zen 4, assuming the technology shows up there as well. And at this point, we have to assume that will be the case.

If there’s a downside to the 5800X3D, it’s that it does not officially support any overclocking. Not only is the multiplier locked, but it also doesn’t support underclocking, undervolting, or any extra performance from Precision Boost Overdrive, which is AMD’s automatic overclocking technology.

The reason for this lack of overclocking support lies in the 3D V-Cache technology, which sees the L3 cache tripled by placing the cache on top of the CPU. This extra cache doesn’t work well at higher frequencies or voltages, with the latter forcing the chip to be capped at 1.35V as opposed to the 1.5V of other Ryzen 5000 chips.

However, that didn’t stop fixers from overclocking the chip using the base clock (BCLK). Increasing the base clock to 104MHz, SkatterBencher managed to reach 4.74GHz with the chip, complete with a DIY YouTube video. Be warned though that overclocking using BCLK can degrade system stability as it affects other system elements including RAM, USB ports, PCIe slots, SATA drives and NVMe SSDs.

This latest overclock is a little more interesting than the previous overclocks, because not only does it have resident overclocking from MSI, TSAIKmanaged to push the chip beyond the 5GHz barrier (via Wccftech), but they managed to do this by keeping the voltage at just 1.2V. It’s worth noting that this was achieved with a single stick of 8GB of RAM running at 1205MHz, proving that this isn’t an overclock you’d want to use on a daily basis.

There are many things that are unknown about this overclock, including what the cooling setting was, but potentially more importantly, whether a new BIOS was used for the overclock. One of the beauties of working in-house at MSI is that TSAIK potentially has access to BIOS versions that we mere mortals don’t. Will we see a BIOS update for the Godlike X570 that allows others to reach such dizzying heights? We’ll have to wait and see.

There’s also the question of whether you should overclock the $450 chip. semi-precise suggests that overclocking the chip can cause a catastrophic failure due to the breakage of the link between the CPU and the 3D V-cache when out of spec.

The post also suggests that the chip shouldn’t have been released to the public in the first place, which is a strong opinion for sure. The underlying message is worth listening to that overclocking the chip can cause problems, especially if you can’t afford a $450 CPU.

I’m sure this won’t stop creators from pushing the Ryzen 7 5800X3D further and further, and while we’re unlikely to see overclocks as high as those seen by the straight Ryzen 7 5800X, which hit 6.1 GHz, I suspect this record of 5, 14 GHz won’t last long.
