What’s This? Ryzen 7 5800X3D Overclocked To five.1GHz By MSI However There’s A Catch


ryzen 7 5800x3d
AMD’s Ryzen 7 5800X3D achieves unimaginable efficiency uplifts in sure functions by “merely” including an additional 64MB of cache onto a Ryzen 7 5800X. We put “merely” in quotes as a result of the vertical die stacking course of employed on the chip remains to be cutting-edge stuff, and AMD needed to make vital concessions to the unique Ryzen chip’s capabilities to permit it to work.

These concessions got here in the way in which of the chip’s overclocking options, in addition to a slice of its clock fee. Whether or not because of the cache die itself or the precarious bond between it and the Core Complicated Die (CCD), AMD acknowledges that the Ryzen 7 5800X3D is much less sturdy than the unique recipe. It restricted core voltage to only 1.3 volts on the brand new mannequin, and likewise disabled Precision Enhance Overdrive.

Precision Enhance Overdrive is the bundle of options that almost all skilled Ryzen overclockers use to govern their processors’ properties. Certainly, virtually each Ryzen processor launched thus far has formally supported overclocking, and AMD provides a strong toolkit for tuning its chips. That toolkit isalmost completely disabled on the Ryzen 7 5800X3D, which makes overclocking the cores moderately tough, although the reminiscence and Infinity Cloth speeds can we altered.

Notice that we mentioned “tough,” not “unattainable.” Regardless of what AMD’s Director of Technical Advertising advised us within the livestreamed interview above, it’s attainable to overclock the Ryzen 7 5800X3D—it is simply tedious to take action and will introduce instability in different components of the system. Overclocking the fats stack of silicon requires adjusting the processor’s base clock (or “reference clock,” extra precisely) as an alternative of utilizing the instruments offered by Precision Enhance Overdrive.

On most motherboards, this is not going to get you very far. Elevating the bottom clock will begin to break every part else in brief order—even 1 MHz is sufficient to begin disabling issues like SATA controllers on some boards. Over at SkatterBencher, they had been in a position to take a Ryzen 7 5800X3D from 4550 MHz to 4741 MHz with the assistance of an ASUS characteristic referred to as Voltage Suspension. Nonetheless, this is not an enormous achieve, and it solely improved efficiency by about 4%.

TSAIK’s CPU-Z validation.

Nicely, MSI’s personal in-house overclocker has apparently been enjoying with one in every of these processors. TSAIK, as he is recognized, submitted a validation to the CPU-Z database with the Ryzen 7 5800X3D working at 5,142 MHz. That is a reasonably vital leap from the circa-4.5-GHz inventory clock. Because it’s only a CPU-Z validation, there are not any benchmarks or anything to gauge the efficiency impression of the overclock, however frankly wanting on the particulars, it in all probability would not be that nice, anyway.

To realize that overclock, TSAIK needed to elevate the reference clock to 113 MHz. We do not know what compromises that required on the MSI MEG X570 GODLIKE board he was utilizing, however we do know that it required him to make use of solely a single 8GB reminiscence module working at simply 1,205 MHz (2410 MT/s). Primarily, it is a single stick working at JEDEC “protected” timings, and the one purpose it is 1,205 MHz as an alternative of 1,066 Mhz is due to the elevated reference clock.

As such, this overclock might be only for bragging rights, not for sensible use. Certainly, given the base-clock-adjusting requirement for overclocking the Ryzen 7 5800X3D, it is unlikely to be a sensible path for any homeowners of this CPU. Maybe Robert Hallock was proper in any case.
