OC 2700x compatible with Aorus B450
OC 2700x compatible with Aorus B450
Hi everyone,
I hope you're all doing well. I'm new to overclocking and have read some guides about boosting the Ryzen CPUs.
My setup is as follows:
CPU: AMD Ryzen 7 2700X
Cooling: upHere RGB LED Liquid CPU Cooler 120mm PWM
RAM: Ballistix Sport LT BLS8G4D240FSE, 2 DDR4 2400 MT/s, total 16 GB
GPU: Zotac Nvidia GeForce GTX 2060 SUPER 8GB
Motherboard: Gigabyte B450 AORUS
I'm wondering if it's worth pushing this CPU to around 4000 GHz across all cores. I've turned off Cool & Quiet and enabled Core Performance Boost in the BIOS. While that feature is useful, I disabled it because it would push the temperature up to about 3900 GHz during heavy tasks and cause significant spikes (from roughly 38°C to 55°C) when idle—something I really dislike.
Core Performance Boost helped raise stability from 3700 GHz to 4000 GHz during intense use, which is why I turned it on. In the BIOS, changing the multiplier reminded me of the tutorials I've seen, but with my current system I can adjust voltage manually using Dynamic Vcore settings (DVID), Dynamic Vcore SOC (DVID), and DRAM Voltage (CH A/B).
I'm not sure how to fine-tune these values carefully, but I'm open to any advice or tutorials that could help. I've noticed the CPU clock occasionally reached 4170 GHz during Cool & Quiet, and I'd like to see if it's possible to maintain stable speeds above 4170 GHz without major problems.
Thanks for your time—I appreciate your thoughts!
I really value your response since, you understand, going through numerous posts and guides makes it simple to follow the correct path.
Unless you're focused on sports or require a significant 10% improvement in core performance with only a minor decrease in single-core efficiency, you've wasted your investment in an "X" Ryzen. Its main advantage lies in the greater PBO boost compared to non-X models. All core OC adjustments reduce frequency and voltage drop during idle and enhance cooling if advanced cooling isn't available.
I really value your response since, when we read numerous posts and tutorials, it becomes quite simple to follow the correct path.
I plan to add more information if someone else asks the same question.
My BIOS settings are now configured as follows:
I activated the Precision Boost Overdrive in the BIOS by going through these steps:
Peripherals --> AMD CBS --> XFR Enhancement --> Accepted --> Precision Boost Overdrive = Enabled
It finally reached a stable speed of 4175 MHz after a long effort, without any overclocking process.
This is what many have discovered about Ryzen. When auto boost is enabled and used correctly, static OC becomes unnecessary. Most Ryzen processors can handle all core overclocking to the same level and lower frequencies compared to their boost values.
Advantages of perma OC include:
- Enhanced multicore performance and reduced reliance on temperature limits, as optimal boost occurs at or below 62-65°C. Even high boosts in the 80s remain manageable.
- Cutoff temperatures typically fall between 90-95°C.
- Voltages can stay consistent while still being fine-tuned via LLC or positive/negative offset settings.
Potential drawbacks are:
1. Single-core performance may drop if the OC level doesn’t match the single-core boost achieved automatically.
2. Higher operating temperatures often require upgraded cooling solutions; standard OEM coolers aren’t sufficient for meaningful overclocking.
Overall, many believe Ryzen tends to be responsive and quick at idle, quickly responding to basic OS and software demands, which actually enhances performance by rapidly activating multiple cores without noticeable delay.
Thank you so much for this interesting info.
Speaking about CPU MHz I have another, maybe stupid, question:
Why the CPU frequency decreases when I start a heavy process?
For example:
IDLE 4175-4200 MHz
GAME 4075-4100 MHz
Is it normal? Why is not the opposite with a higher frequency during a heavy process?
Obviously I still have all the same settings I already wrote about.
Another factor might be the specific games themselves, as they don't always demand much CPU capacity. Temperature is also a consideration; excessive CPU usage increases power consumption and heat generation. If the temperature rises above 62-65°C with PBO or reaches high 70s during manual overclocking, the system will automatically reduce performance.
One of the factors is the power and thermal constraints of PBO. The algorithm simply prevents all-core boosts from reaching higher frequencies when loads increase. I have a 3700x with an all-core of 4.3ghz manual OC. However, with PBO fully optimized, I only see all-core frequencies fluctuating between 4.2 and 4.32ghz based on the game, and a peak of around 4.12ghz for intense tasks. Trying to lock a static frequency proved more advantageous because it reduced temperatures and improved frame times in several cases, even though PBO technically offered higher boost clocks. Ultimately, the decision depends on your specific setup and whether you can achieve a solid all-core performance.
I discovered on my ASUS x470 with Auto OC level 2 and PB turned on, the voltages were climbing up to 1.57 volts and maintaining that level during gaming, which is quite high for me and caused a few crashes. Using Manuel OC at a steady 4.275ghz gives me a more stable range of 1.4125-1.4187 volts, with better temperature consistency. It still lowers clocks in idle and keeps temperatures around 58°C during gaming and 27-35°C in idle with the Ryzen boost (we all appreciate the explanation for Intel fans!). This works well for me, but every system is unique and a B450 might not handle stable over 4.2ghz cores.
This was also my view, backed by my laptop experience (I used ThrottleStop previously).
Thank you very much for clarifying your situation. I particularly value the information about temperatures, as I understand it's typical for high-end CPUs to experience spikes at 2700x and similar speeds. I attempted to find a method to keep them stable, but I didn’t mind much when performance improved during games or heavy tasks.
I believe I’d prefer overclocking only if it brings a clear financial benefit (above 15-20%), otherwise I lean toward the idea of CountMike.
Could you clarify what you mean by "Auto OC lvl2"? Is it another feature I missed?
Regarding catching the ball, I’d also like to ask a few more questions if possible:
1) Have you overclocked using a stable or dynamic Vcore in BIOS settings?
2a) Are you familiar with Dynamic Vcore (DVID), Dynamic Vcore for SOC (DVID), and DRAM Voltage (CH A/B)?
If I were to proceed with an OC, what steps would you recommend?
3) Did any of my friends give me 3D Marks for benchmarking? Would it be beneficial to check a good overclock?
Thank you all, I’m learning a lot and improving my knowledge.
It’s not that simple to find people who are willing to share their experiences or ideas like you.
Perhaps it seems impossible, but trust me… it isn’t!
