Latest AMD Chipset Driver 5.01.29.2026 WHQL Adds 3DV Cache Optimization 1.0.0.7
AMD is preparing to release the latest version of its Chipset software. Version 5.01.29.2026 WHQL should be of particular interest for users planning to buy an upcoming Ryzen 7000X3D series processor. The chipset driver includes the "3D V-Cache Performance Optimizer driver" component, version 1.0.0.7. This gives Windows a degree of awareness of the asymmetric nature of 3DV cache on the 16-core 7950X3D and 12-core 7900X3D, where only one of the two CCDs (chiplets) has the 3DV cache memory, while the other is a regular "Zen 4" CCD with 32 MB on-die L3 cache. This awareness should in theory improve performance in less-parallelized workloads (such as games). The AMD website doesn't yet list this driver, but it should appear as we head closer to the market-availability date of the 7950X3D and 7900X3D (February 28). From the looks of it, the optimization works for both Windows 11 and Windows 10, so those on the older operating system for reasons, can keep rocking it.

It is ONLY important for 2 and more mixed CCD architectures, where not all of them have VCache on them -- like 7900 or 7950 with 3D Cache (where only one CCD has 3D Cache and one doesn't).
Looks like you just read the title. :p
The "OS agnostic" remark is pretty amusing to me - for 3 years Ryzen at every turn has been heavily dependent on complementary Windows optimizations just to work properly, and now according to random Twitter dude it's suddenly "OS agnostic"? :rolleyes:
As for the Core Flex feature, I'm not fully convinced yet that it's an AMD-wide feature contained in AGESA. We've seen proprietary features under the Tweaker page before (remember the dynamic OC switcher on Dark Hero that would "automatically" toggle between all-core and PBO depending on load?). I don't believe for a second that AMD will solve this problem through AGESA alone, without any help from Microsoft or chipset drivers.
The goal with dual CCD is to have 1 that clock very high if you run somthing that aren't cache sensitive, and one that have a lot of cache if you run something that does. If you happen to run something on the wrong CCD, you still run it on a fast Zen 4 core anwyay.
Intel on the other side, would have a really hard time if games would run on E-Cores by mistakes.
But in the ends, as long as the scheduler is doing it's job properly, this is not a big deals. The main drawback in my opinion of Intel E-cores is the fact they had to disable AVX-512 to maintain the same instruction set across all cores.
