Reduce Lower Cinebench score during overclocking. Assistance needed.
Reduce Lower Cinebench score during overclocking. Assistance needed.
Right now my setup is performing well with a minor overclock at 3.65GHz. However, I’m noticing that my Cinebench R15 scores drop slightly after this point, and I haven’t identified the reason yet. It’s possible my standard RAM isn’t providing enough bandwidth as an issue arises. I’m not sure if upgrading to a different type of RAM would help, since the ones I have aren’t particularly high-end models like Corsair Vengeance or GSKill Trident Z. Below are the details of my hardware:
- CPU: Ryzen 7 1700X
- GPU: ASUS Strix GTX 1070 OC
- RAM: Single stick, 16GB, 2400MHz DDR4 (Patriot PSD416G24002), specs: 17-17-17-39 timing, 1.2V
- Motherboard: ASUS Prime X370 Pro
- Storage: 480GB Crucial BX300
- Power Supply: EVGA 750W Gold
- CPU Cooler: Coolermaster Hyper 612 v2
- Overclocking steps I followed:
1. CPU Core Ratio set to 36.5
2. VDDR CPU Voltage adjusted to 1.337V
3. VDDR SOC Voltage increased from 0.900V to 1.050V
4. DRAM Voltage set to 1.2V with Auto mode
5. VDDR CPU Load Line Calibration at Level 1
6. VDDR CPU Current Capability enabled at 110%
7. VDDR CPU Power Duty Control set to Probe
8. VDDR CPU Power Phase Control optimized
9. VDDR SOC Power Phase Control set to Extreme
10. Performance Core Boost disabled
11. Global C-State Control enabled
Cinebench R15 results:
- Overall: 1582 (CPU)
- Single thread: 147
- CPU single: 407.9
- Multi-thread: 4489.3
My scores have improved slightly after adjusting the core ratio and VDDR settings, but they’re still below expectations. The system runs cool enough with temperatures around 65°C after an hour of Prime95. I’m now testing a higher core ratio of 37 (3.7GHz) and lowering VDDR CPU voltage to 1.345V while keeping other parameters constant. The new Cinebench R15 results are:
- Overall: 1531
- Single thread: 421.4
- Multi-thread: 4554.0
Any advice on what might be causing the drop would be helpful, as I want to avoid damaging my hardware while pushing beyond 3.65GHz.
If several pairs of cores fail to reduce their multiplier (and therefore clockspeed), it likely isn't a temperature-related throttle problem. However, power-envelope throttling might still be occurring. Test by adjusting the OC in small increments and observe if the clock speed improves to match or exceed stock levels.
Does the operating system contribute to the processor slowing down?

I haven't run Prime 95 @ the 3.7GHz, only tested it with Cinebench. When I saw the lower benchmark results, I was puzzled. There were temperature spikes, but not reaching 65 degrees. But is the processor slowing down while I ran Cinebench? CB keeps the CPU at full capacity.
I'm not sure how to be honest, what would I notice if the CPU was throttling during Cinebench? Yes, the CPU is at full capacity while it's running. The clock speed will decrease for one or more cores. For temperature-based throttling, you can try Ryzen Master while the benchmark is active and observe any drops. I believe HWinfo64 also shows if power envelope throttling occurs. Throttling occurs when a core's temperature becomes too high or the CPU surpasses its power limits. The CPU adjusts the multiplier to protect the core.
