Your PBO seems unstable. It might be time to reassess its management.

The number around 4000 points appears significant mainly because of CL18 and two rank entries, though it's still possible in theory. Have you ensured all background applications were stopped before setting it to bench? A 3600MHz frequency works well. Switching to 3800-4000MHz could improve performance, but it won't guarantee perfect 1:1 compatibility with the FLCK. Running asynchronous operations will likely reduce performance more than faster RAM would help. If you upgrade to new RAM, aim for CL16 and target a total of four ranks—two 16GB units or four 8GB units. In the meantime, consider lowering voltages using the curve optimizer; this can reduce power usage and temperatures while allowing PBO to operate at higher boost levels, potentially compensating for some performance gaps without needing a RAM replacement.
My 5950x performs about 31k under PBO, possibly varying with different motherboards. Your setup supports up to 237 watts when enabled. You're using a 3200CL16 kit at 3666CL18, currently running at 150A TDC for a peak of 217 watts—scoring R23.
It's definitely in 2 and 4, but locating the top 5950x RAM is proving difficult.
Your setup appears to be using 142 watts, while 25-26kW is typical for stock 142/95/140. Disabling limits lets it reach 248 watts in Cinebench R23.
The workload is distributed over 16 cores with multiple threads, preventing any single core from being overloaded. Temperature management is the main priority. When cooling is adequate, 250 watts falls within the typical safe range for voltage. At 248 watts, the standard AMD curve dictates the voltage settings.
What cooling method are you considering? With just 12°C headroom, even the most efficient airflow might not be enough.
Arctic ii 280mm AIO stands out as a consistently top choice, especially compared to the highest 360mm models. A 280mm unit offers 28% more surface area than a 240mm model. In contrast, a 360mm AIO only provides about a 10% increase over 280. The 280mm variant delivers significant benefits over a 240 for high power output and better BTW. I found it performing around 92°C after a 10-minute R23 test. It has TDC limits, reaching about 217 watts at 85°C and running much quieter. I’m also using the PBO negative curve optimizer, with 4.55GHz all-core and 5050MHz boost.
