Solved 3900X OC achievements in gaming
Solved 3900X OC achievements in gaming
I ran some tests using Ryzen Master and achieved a score of 6600 with the stock speed in Cinebench 20. Then I adjusted it to 4Ghz, which improved to around 7000. However, in games I notice lower FPS when the CPU is overclocked, creating a noticeable difference. Why is that?
Manual OC adjustments for Ryzen 3000 can boost multithread efficiency but hurt single-thread speed.
Gaming will increasingly rely on either multithread or single-thread capabilities.
If certain titles depend heavily on single-thread performance, the outcome will be predictable.
You disabled the CPU's ability to reach 4.6ghz when it needed it most.
This issue contributes to why manual OC on Ryzen 3000 is often ineffective, yet users persist despite its limitations compared to other options.
The optimal approach for maximum performance is to leave the system unchanged:
- Stick with a balanced power plan. High performance yields no benefit.
- Avoid excessive cooling efforts; better thermal headroom means the CPU can boost multithread more effectively.
Manual OC on Ryzen 3000 improves multithread efficiency but sacrifices single-thread speed.
Gaming will increasingly rely on one or the other, so outcomes will vary.
You halted the CPU from reaching 4.6ghz when it needed it most.
This issue contributes to why manual OC is considered poor, yet people persist despite its drawbacks.
The optimal adjustment for Ryzen 3000 is minimal changes:
- Stick with a balanced power plan; high performance offers no benefit.
- Overcool the system excessively—greater thermal headroom pushes the CPU toward boosting multithread performance to that 4.6ghz single-thread limit.
- Raise RAM frequency up to 3733mhz and CL16/17, then fine-tune timings with the Ryzen Dram Calculator.
Yes, prioritizing RAM is crucial for gaming performance. But regarding Ryzen and overclocking, or enabling auto OC, there are many limitations and differences. For my R5 3600, I managed to get the optimal thermal management, safest voltages, and top performance through manual adjustment. At default settings, when pushing my CPU under stress, my SVI2 TFN voltage stabilized at 1.3v, while my all-core OC reached only 4GHz. My temperatures stayed around 75°C. With PBO enabled and auto OC turned on, my all-core speed surpassed 4.2GHz, but this came with increased Vcore, EDC, TDC, and PPT values, along with higher temperatures. It caused frequent throttling to maintain stability, resulting in better benchmarks than stock but at the expense of performance consistency and higher voltages. Using manual OC allowed me to lock my CPU at 4.2GHz @ 1.3Vcore. My PPT, EDC, and TDC stayed within chip limits, while my Vcore ranged from 1.287 to 1.3, keeping me consistently at 4.2GHz. Under stress, temperatures remained around 75°C, delivering the best benchmark results. Single-core scores were only slightly behind those with PBO, but multicore improved by about 4% versus PBO and roughly 5-10% above stock.
At stock configurations, keeping an eye on your core clocks while playing can reveal that many cores are likely operating faster than 4GHz. The CPU gets a boost when the game demands more processing power to maintain higher speeds for improved performance.
CPUs such as the 3900x gain less from all-core overclocking compared to models like mine (R5 3600) since they’re built to handle extreme boosts. Achieving OC speeds of 4.4–4.6 GHz across all cores on these CPUs is highly unlikely.
I didn't intend for anyone to misinterpret my statements.
I mentioned a performance tweak the user could apply, but not specifically for gaming or emphasizing RAM improvements.
The opinion is open to discussion.
I won’t rely on AMD engineers' assessments of what’s safe for their CPUs, especially when pushing beyond original specifications.
Overclocking can actually exceed the intended limits—PPT, TDC, and EDC values aren’t hindrances but indicators of heat.
A standard cooler wouldn’t make much difference; simply upgrading the cooling system would suffice.
Other suggestions seem driven by group pressure rather than personal insight.
For everyday users: focus on better cooling and memory.
For others: feel free to experiment freely.
I hope people recognize that Intel CPUs aren’t treated the same.
I don't understand why you were upset.
I matched your point about adjusting the RAM, and I've discussed my own CPU tweaking experience over the past 30 hours.
I also have a powerful cooler set up.
All testing—including the stock unit—was done with an aio featuring a 360mm radius.
I regret if my interpretation seemed unclear. My goal was simply to find common ground with you.
I focused on gaming performance since that’s where Ryzen delivers the most value through memory adjustments, at least from what I understand. I believe running the CPU at higher frequencies helps more in other operations like rendering and compression.
EDIT:
The main reason it matters in gaming is that Ryzen’s cross-chiplet latency is its weakness compared to frequency and IPC. You’ll notice significant improvements because faster RAM—especially 3800 MHz with a 1900 fclk—supports better cross-chiplet communication, reducing latency.
