Rumor: AMD Ryzen 9000X3D with full OC support
Wccftech sources indicate a significant change to the upcoming X3D lineup.
As we get closer to the launch of the Ryzen 9000 series, information about the Zen5 desktop CPUs is getting more and more detailed. According to the report, the upcoming generation of the X3D series, known as the Ryzen 9000X3D, will support overclocking, an interesting change to one of AMD’s most successful series.
The previous two generations of X3D, featuring the Zen3 and Zen4 architectures, did not support full overclocking. While there were optimization techniques and the ability to select overclocked memory, there was no easy way to increase the clocks or multipliers like with normal CPUs. AMD has always pointed out that overclocking can cause instability, and the only way to optimize performance is to use technologies like Precision Boost Overdrive enabled on the 7000X3D series.
The next generation will overcome these limitations and support ‘full overclocking’. This means access to CPU voltage or clock changes that are not manually adjustable even on the Zen4 series.
With the next generation, AMD introduced some nice new features for their Ryzen 9000X3D CPUs running Zen 5, but among those features we’ve been able to find out is full support for OC. Yes, that’s right, it’s not just PBO or CO tuning, enthusiasts on the AM5 platform will get full overclocking support with the next-gen 3D V-Cache CPUs.

It is noted that although supported, AMD may provide safeguards to limit overclocking to safer values. A byproduct of using 3D V-Cache is that it is more sensitive to voltage changes.
| Ryzen X3D Series and Overclocking (Simplified) | |||
|---|---|---|---|
| VideoCardz.com | Manual OC | Car OC | Memory OC |
| Ryzen 5000X3D Zen3 | ❌ | ❌ | ✅ |
| Ryzen 7000X3D Zen4 | ❌ | ✅ PBO | ✅ EXPO |
| Ryzen 9000X3D Zen5 | ✅(with guarantees) | ✅ PBO | ✅ EXPO |
The same leak also shared details about Zen5 memory support and overclocking capability. The new series is said to consume less power and support enhanced overclocking for DDR5 kits. Based on preliminary data gathered from qualification samples (which will be the same or better than retail units), the Ryzen 9000 series is still targeting DDR5-6000 memory as the sweet spot, but the upper limit will be increased to 6400 MT/s. 1:1 FCLK (Infinity Clock) to MCLK (Memory Clock) ratio. In addition, they will support EXPO memory up to 8000 MT/s with 1:2 ratio in 4-DIMM mode.
AMD Ryzen 1:1 (MCLK:FCLK) ratio memory support
- AMD Ryzen 3000 “Zen 2” Sweet Spot – DDR4-3800
- AMD Ryzen 5000 “Zen 3” Sweet Spot – DDR4-4000
- AMD Ryzen 7000 “Zen 4” Sweet Spot – DDR5-6000
- AMD Ryzen 9000 “Zen 5” Sweet Spot – DDR5-6000 (Upper Limit – 6400 MT/s)
It is noted that the board’s partners are working on 9000 MT/s and even 10000 MT/s storage support, which will be possible with a ratio of 1:2. It looks like the days when Ryzen CPUs couldn’t compete with Intel in supporting high memory specs may be over. This, along with full support for overclocking in the X3D series, could make Ryzen one of the most exciting updates to date.
