AMD understands that there’s a lot of demand for its X3D processors and for good purpose too, since they provide a number of the finest gaming experiences. As such, the corporate plans to launch a brand new 6-core Ryzen 5 9600X3D for individuals who could not wish to spend high greenback on a 9800X3D.
What makes X3D particular is the densely packed final degree cache (LLC) whereby the L3 (degree 3) cache is 3D die-stacked such that there’s a entire lot of it that the cores can entry on demand all throughout the smallest footprint. That is mentioned to assist with latency particularly, and video games occur to be fairly delicate to it since they’re a combined workload and so there’s quite a lot of to-and-fro.
Nevertheless, regardless of that truth, customers have observed micro-stuttering and freezes on Ryzen X3D CPUs. Though there isn’t any official repair, a number of the affected customers have managed to resolve the problems by tweaking a motherboard setting. The tweak is expounded to a setting referred to as “GLOBAL C-STATE CONTROL” (it could be referred to as one thing else by your motherboard vendor) and altering it to ‘Enabled’ from ‘Auto’ may repair stuttering and lag-related points in video games.
If you’re not conversant in them, Processor Energy Administration is completed via Superior Configuration and Energy Interface (ACPI) P-states or C-states. Whereas P-states or efficiency states deal with CPU voltage-frequency scaling, C-states take care of CPU sleep states in order that a number of the CPU capabilities, which aren’t mandatory at that second, are disabled. The P-states and C-states work collectively to make the processor run extra effectively. It helps the OS and apps decide which cores will be parked.
The World C-state management setting helps customers handle not solely the DF and CPU core C-states but in addition the I/O C-states too. For these questioning, DF right here refers to Information Material or AMD’s excessive bandwidth Infinity Material interconnect between CPUs, GPUs, and extra, on AMD programs.
By default, that is set to “Auto” which additionally signifies that it’s “Enabled” by default. Nevertheless, within the case of X3D elements, Auto could set this setting to “Disabled” and thus manually toggling it to “Enabled” could also be mandatory.
X3D processors, the twin CCD (core complicated die) ones particularly, have their V-cache on a single CCD. If the CPPC (Collaborative Processor Efficiency Management), which lets an OS like Home windows management the “most popular core” and clock pace increase, is not working optimally to assign the right gaming CCD, then this repair may nicely work.

We ran a benchmark on our Ryzen 9 9950X3D to see if toggling the settings would make a distinction, and nicely, it did not within the case of AIDA64. Nevertheless, since this can be a artificial take a look at that measures cache and reminiscence completely, we won’t definitively conclude that the repair can even not make a distinction within the case of video games. Do be aware that we see a distinction in clock speeds between the 2.
One other treatment for stuttering is to disable the monitoring of the “Energy %” metric on MSI Afterburner in case you have it on. This has been a long-known difficulty and actually will help you even in case you are not utilizing an X3D CPU.
