How do I push my overclock further?

Hughes_635 · March 7

Hello! yesterday I started overclocking my ryzen CPU little by little with PBO and the curve optimizer. The temperatures on my cpu are low (I think) when running Cinebench r23. Before overclocking I got a score of 12000 on multicore, Now I get 15303, But when I Put the curve optimizer in every core, negative at 20, cinebench just crashes. Also I put PBO with the limits disabled and the overclock override at 200Mhz+. I dont know how to make my cpu better, i dont know if my scores are good. My specs are:

Motherboard: Crosshair VIII Dark Hero
CPU: Ryzen 5800X (top speed 4.8Ghz)
GPU: RTX 3080 10GB RoG Strix
RAM: Trident Z Neo 3600MHz (4 x 8GB)
PSU: RoG 1000W
Cooling: iCUE H150i Elite Capellix AiO
Storage: WD Black SN850 2TB

Here are some screenshots of everything:

I dont know how to overclock, I just saw a youtube video that told me to imput those things. The guy modified some voltaje settings, but I dont know how to do it and I dont want to break my pc)

I am no technical expert in this regard, just growed with videos and theoretical knowledge. How about a plain all core overclock with a higher voltage offset or in the worst case, a locked steady voltage? CPU VDD of 1.4 V is perhaps what I would consider the safe limit.

PBO and all are just very conservative and try to achieve every bit of MHz with the lowest voltage. You can try to find that spot manually. Else idk, can you not just keep increasing/extending the curve? More voltage and more frequency.

I know the basics of overclocking but never felt the need to risk my hardware for a bit of perf increase.

In general, to achieve higher clocks, you need to increase the core voltage to keep the CPU stable. This has the side effect of increasing power usage (and temps) so you need to provide adequate cooling all the time (extreme overclocks use liquid nitrogen when all other methods are no longer enough). And you need to make sure the memory is keeping the pace too.

The technical challenge of balancing all that can be fun, I admit. I'd go for it with a discarded computer or for youtube content, but for day-to-day use, stock settings are really enough and I prefer to keep my hardware's longevity intact.

For those who dabbled into crypto-mining, this is often the reverse settings. The goal is more efficiency than raw performance. Often, you reduce core voltage and limit power so that the GPU outputs a max of computations while using the least amount of power.

Have a nice day !
