Core overclocking talk and possibly a manual
Core overclocking talk and possibly a manual
Now we have per core overclocking options available in both z370 and X470 models. This offers advantages for overclockers. It allows you to run one core at a higher speed if needed, but you still need to configure processor affinity in the task manager to utilize the per-core higher overclock effectively.
I'm curious about this feature: is it feasible to always keep just one core active at a high frequency, such as 4.3ghz, while keeping others at lower speeds? Is achieving stable per-core high overclocks achievable, especially with mid-range cooling solutions like the Cryo H5 or Scythe Mugen 5 at reduced voltages? Have any experts successfully increased FPS in games while maintaining lower temperatures compared to your current settings?
A bit of background on why I'm seeking this information: I own a 6600K and an 1600K system for friends and myself, plus an older HP Phoenix workstation where I upgraded the GPU long ago. I’m now using my GTX 970M laptop as my daily device. Everything is about to change since I finished school and began working. I’m planning to invest in a dedicated gaming PC for my living room soon, which will likely take at least a year to build.
I’m starting this project to create a custom battle station and join the #pc master race. I just started and hope someone will create a new thread about these latest overclocking experiences.
R7 2700x and Ryzen Master program highlight the best-performing core (gold star above) to determine which one should be optimized most. It's common for one core to outperform the others, so optimizing only the active cores yields the best outcomes. Running on half cores is also an option, allowing further optimization. Personally, I didn't notice any noticeable performance improvement using this method. Optimizing all cores to 4.2 GHz consistently delivers the best results.
Thank you for sharing your experience. You mentioned 4.2ghz is the top setting for all-core configurations. What core did you achieve with your gold core? Possibly even a combination of gold and silver? I mainly play Dota 2 using Discord and a few apps for game information.
As I mentioned in my previous post, I aim for a living room or gaming setup with a large format display running at 120/144hz. This would work well for Dota 2. However, I also enjoy open-world games like Elder Scrolls and the Witcher series, which are more demanding than Dota. Pushing all that FPS on a single core at 4.3ghz won’t be sufficient. Going all-core might reduce the available Hz. That’s why I started considering per-core specs. Maybe 2 cores or one CCX with 4.3ghz, or even 4.35? Have you seen any benchmarks like that? (I’m leaning towards AMD. My friend with a 6600k got an RX470 with an LG 75hz 1080p freesync, and my other friend had an RX580 with 21:9 75hz freesync—both loved it, and I was happy to suggest it.)
Also, how stable was your OC on the golden core and what Vcore did you use? Were there any load line calibration issues or temperature spikes? This is why I was seeking a more detailed guide about per-core specs.
For Gold core 4.3 the performance was satisfactory, though program limitations in selecting cores didn't significantly impact results since all cores run at a steady 4.225GHz. The GPU isn't powerful enough to notice differences, and games that support it can't utilize more than 10-15% CPU usage effectively. A 1080Ti might help, but most titles aren't optimized for single-core performance. Compare this with an i7 8700K paired with a 1080, offering about 15% better IPC with only marginal gains in FPS.
i'm wondering if i should go for a full 700k 1080ti setup, similar to a 2600x successor and a vega 56 successor on a 34" 1440p 21:9 screen. let's check. again, thanks for the details, i'll ask my friend to look into a 1600 ccx oc and see if he can get better performance with higher OC and processor affinity settings. he currently has an oc of 3.85 across all cores, but he uses the stock cooler and dust is a big issue in our area. so improved oc means better cooling and maintenance.
