msi’s-kombo-strike-bios-feature-boosts-ryzen-7-5800x3d-performance-but-there’s-a-catch

We’re followers of the Ryzen 7 5800X3D round right here. Sure, it is dear for what it’s; that a lot is inarguable. Still, the truth that you may slap a brand-new processor right into a two- or three-year-old motherboard and instantly get chart-topping gaming efficiency is extraordinarily cool. Your creator right here threw one into his ASRock X570 Taichi and noticed instant enhancements in just a few video games—despite the fact that he was coming from a higher-clocked Ryzen 7 5800X.

Still, gaming efficiency apart, AMD’s 3D V-Cache wunderkind does fall down a bit usually efficiency on account of its decrease clock fee. Don’t get us improper—any Zen 3 processor at over 4 GHz continues to be a lightning-fast CPU within the broader scheme of issues. The standard-issue 5800X can scrape the sting of 5 GHz with none guide OC, although, and that is a variety of clock fee to make up, significantly contemplating that the 5800X3D is locked for overclocking.
List of MSI motherboards with Kombo Strike beta BIOS updates obtainable.

Owners of sure MSI motherboards is likely to be in luck, in the event that they wish to strive bumping the clock fee of their AMD stacked-cache CPU. The firm simply launched beta BIOS information for a handful of B550 and X570 motherboards that add a characteristic generally known as “Kombo Strike”. This oddly-named perform has three settings, cryptically labeled 1, 2, and three (in addition to “Disabled”, in fact.)

MSI says Kombo Strike will enhance the efficiency of the Ryzen 7 5800X3D by as a lot as 5% on the most stage, however that it is best to “make sure CPU Cooler is strong enough to handle the heat.” Going by that description and what we all know of the lockdown on the Ryzen 7 5800X3D, we suspect MSI’s discovered a solution to bump the facility restrict for the chip, which might permit it to spice up greater.

This expectation is corroborated by some testing carried out over at WCCFTech. Those fellas examined Cinebench in each ST and MT varieties on the 5800X3D at the entire doable Kombo Strike settings, and located that the upper the quantity, the extra it improved multi-threaded scores—certainly by about 5% on the highest stage. Single-threaded outcomes have been basically unaffected by Kombo Strike, which is in line with what we might anticipate assuming that it’s a tweak to the facility restrict.
However, these beta BIOS information additionally allow under-volting for the Ryzen 7 5800X3D. See, together with the overclocking lockdown, AMD additionally disabled all voltage controls on its latest child. That means no Curve Optimizer, or any undervolting in any respect—except you’ve a board that helps it.

ASUS has apparently supplied undervolting management for this CPU on a few of its boards, and now we see MSI following go well with. If you are questioning why undervolting may enhance single-threaded efficiency, it is as a result of it could actually considerably scale back the quantity of present drawn and warmth produced by the CPU, permitting it to spice up greater.

If you’ve one of many above-listed MSI motherboards, you may head over to the discussion board moderators’ Google Drive to seize the file.
