Core speeds for Ryzen 7 2700 remain capped at base rates
Core speeds for Ryzen 7 2700 remain capped at base rates
I have a Ryzen 7 2700 and I suspect something’s wrong. I think I’m seeing fewer frames in my games lately, which might be connected to this. My Base Clock is 3.2GHz and the Max Boost Clock reaches up to 4.1GHz. All cores run at about 3475MHz when idle, which I confirmed using Ryzen Master and OCCT. When I ran a stress test with OCCT for three minutes, the clocks dropped to 3.4GHz, temperature rose from 40°C to 65°C, power usage jumped from 25W to 60W, and the fan speed increased from 2000rpm to 2500rpm. I changed the power plan from Balanced to High, but nothing improved performance. Game clocks stayed the same as idle, but stress test clocks didn’t either. It looks like maybe boosting the Boost Clock could help with gaming. Any advice?)) RTX 2060 HyperX 2x8 2666 ASRock B450 Steel Legend Ryzen 7 2700 Kingston 480GB SSD
I'm not a math expert, but from what you said, 3.4 GHz is definitely higher than 3.2 GHz, so the chip should be performing well. You're also getting a strong boost from using all the cores together, which usually adds a noticeable improvement. A 4.1 GHz frequency would typically be seen only with a single-core setup. For extra optimization, consider resetting the BIOS and turning on PBO—this might give you even better results if your cores are running cooler than 60°C.
I understand what you mean. When I first wrote this, I assumed the base frequency was around 3.5GHz in idle mode, but after checking the CPU specs, it's actually 3.2GHz. I’m confused about why it increases when not needed and decreases during stress tests with full CPU usage, even though that seems logical. In idle, the clocks are near 3.5GHz, but in Dota 2, they stay constant. It’s going to be tough to adjust to this behavior.
You're asking about the consistency of clock speeds across different scenarios. It's normal for all cores to run at the same speed when idle, during games, and in stress tests. The variation you're seeing is typical. Regarding the performance differences, your experience with a similar i5 6400 showing slower results compared to others is common. The CGDirector scores you mentioned reflect real-world performance data, so yes, it's within the expected range.
The enhancement process in these chips is quite intricate, yet with CPB2 it activates when possible, up to its limits. Several elements influence performance such as the motherboard, PBO status, and the specific silicon chip. Zen+ primarily lowers clock speeds only when idle, favoring power conservation by putting cores to sleep while maintaining high clock rates. This results in a more responsive and efficient processor. You can reliably expect around 3.2 GHz for all-core workloads (assuming a suitable motherboard). Achieving this demands careful attention and effort during benchmarking to ensure fair comparisons. Background activities from Windows or other programs might affect results. Lowering the operating temperature below 60°C can improve performance, and memory speed also significantly impacts Cinebench scores.
