i7 7700K Overclock help?
Hey, I might arrive late to the discussion when this question comes up. I'm still getting familiar with the OC scene and haven't found many resources on how to boost my CPU's performance beyond normal limits. I've seen some folks manage to push their CPUs to around 5.0 GHz or even 4.9 GHz, which would be great. I have a custom liquid cooling loop for both my CPU and GPU, so I shouldn't have major thermal issues. Any advice would be really appreciated.
I discovered this spreadsheet (link). It seems quite useful. The performance of your chip really hinges on the luck of the silicone lottery. My 7700k hit 4.9 before I delidded, yet managed 4.9 with almost no additional voltage. After removing the delidding, it reached 5.0, but didn't go further. It would boot up to 5.1, though it wouldn't run any benchmarks.

I'm not very confident about delidding the CPU yet, so I'd like to share some numbers and see what I can achieve first. Maybe it's related to my current OC settings—since I got the system prebuilt from a company in Canada who asked them to overclock it. But whenever I load GTA V on the main boot screen, it flashes (I can't describe it well) and disappears when the loading screen appears. Also, I'm seeing low 30 frames at high settings even with an overclocked GPU. Any suggestions? All other games seem to run normally. The graphics driver is up to date.
Honestly after removing my CPU, I wouldn't suggest doing it. What kind of FPS do you see in the GTA benchmark? It should be significantly higher than 30. My machine with a 7700k, GTX1070, 32 GB 3200 and Ultra settings was already surpassing that. Recently I started playing GTA for PC (originally on 360) and installed it, but I remember it was stuck at around 60 FPS during the test. I can try running it again to confirm.

My 7700k stopped at 4.9 before I delidded, yet it managed to reach 4.9 without needing much extra voltage. After removing the delidding, I was able to get 5.0, but not beyond that. It would boot up at 5.1, though it wouldn't run any benchmarks. This is exactly what I experienced. Eventually, I started seeing BSODs at 5.0 as well, which felt like a disappointing outcome after the new 5.0GHz chip lost its edge. Playing games at 5.0GHz isn't too different from 4.5GHz in practice.
After removing my CPU, I wouldn't suggest it for you either. The FPS on the GTA benchmark is significantly higher than 30. On my system with a 7700k, GTX1070, 32 GB 3200, and Ultra settings, I was getting more than that. Recently I started playing GTA for PC from scratch (originally on 360) and it ran fine, but I remember it consistently stayed at around 60 FPS. During the game, especially in crowded or dense areas, it dropped to about 35 FPS. I have the latest drivers installed and the game is running on my M.2 SSD. I'm still trying to figure out what's happening.
