Overclocking the AMD Ryzen 9 9850X3D: What Happens?

Overclocking Potential of the 9850X3D

• 💡 The 9850X3D, like the 9800X3D, is designed to be overclockable due to its flip-chip design, which places the cache under the core for better cooling.
• ⚠️ Despite this, the author believes the overclocking potential is not as significant as one might hope, stating it's "not good in my opinion."

BIOS and Overclocking Settings

• ⚙️ The experiment uses the latest ASRock Taichi BIOS, with a focus on manual overclocking via the BIOS rather than Ryzen Master to avoid past criticism.
• 🚀 Precision Boost Overdrive (PBO) is explored, which lifts CPU limits (PPT, TDC, EDC) rather than directly increasing frequency.
• 📉 The curve optimizer, a form of undervolting, is discussed as a popular AMD overclocking technique to manage heat and improve stability with good silicon.

Testing and Results

• 🎮 Cyberpunk 2077 at 1440p is used for testing to provide a realistic load on the CPU without being overly demanding on the GPU.
• 📈 Out of the box, the 9850X3D shows slightly higher clock speeds than the 9800X3D, reaching mid-5 GHz, but not significantly exceeding its advertised 5.6 GHz.
• 🚫 Enabling PBO with a 200 MHz boost override did not result in a noticeable FPS increase or higher sustained clock speeds in games.

Manual Overclocking Attempts

• ⚠️ Attempts at manual overclocking, such as setting a fixed 5.7 GHz, resulted in instability and crashes, even with increased voltage.
• 📉 The author found that even with PBO enabled and power limits raised, the CPU struggled to exceed its stock boost clocks, suggesting limited headroom.
• 📊 Cinebench tests showed immediate crashes or instability when attempting higher manual frequencies, indicating the CPU's limitations.

Conclusions on 9850X3D Overclocking

• 🤏 The author concludes that the 9850X3D offers minimal overclocking gains, with most of the performance already squeezed out by AMD.
• 💰 While the 9850X3D launched at a $20 premium over the 9800X3D, the author suggests that if a good bundle or price for the 9800X3D is available, it might be a better value as the real-world performance difference is negligible.
• 😴 For most users, leaving the CPU at stock settings is recommended due to the limited gains and potential instability from overclocking attempts.
