Why is my FX 8350 slowing down?
Building a custom M5A99FX Pro setup with the mentioned components and configurations. I'm working on achieving 5.1 or 5.2 GHz and facing throttling issues during CPU stress tests, even when pushing to 1.52 GHz. The fans are set up properly, but I need more insight into why this happens.
You're pushing that cpu hard for not being able to afford a replacement. I suggest you run it at a vCore of no more than 1.45 and a temp of no more than 55c max on cpu temp and package temp. There is a bit more margin according to amd overdrive but it sounds like you need to be extra careful.
At 4.6ghz it exceeds the single core and multithreaded performance of the 9590 and without supremest cooling plus max you'll struggle in the 4.8-5.0 range to keep it within a good target temperature. The cooler will cost more than it's worth to overclock that high.
Others have said they got to 5ghz at 55c with a vCore at around 1.45 using a corsair h100 so you should be thinking about turning things down rather than up. There simply isn't anywhere more to go with that cpu.
The thing you can do is use faster memory like 2133 or 2400 and it'll be ok-ish for a while but you might not play every title on the highest settings. Besides that is the put newer gpu in it approach.
You are currently hovering on the margin of close to fryvoltily. That 5.0 to 5.1 gives about 18points gain in a benchmark aka does absolutely nothing significant so there is absolutely no reason to push it that hard.
What you might be able to try at 1.45v is switch off two or four cores and treat it as a 6350 or 4350 and try to get 5.2ghz that way if it doesn't exceed 55c. That will bump single core performance marginally but trim multithreaded, probably not worth bothering with. Tho you might also be able to run it at a lower vCore than 1.45v with some of the cores switched off.
Beyond that, save for upgrade.
You should also consider the amount of CPU power. The Ryzen 5 1400 delivers 354 single-threaded and 1932 multithreaded results at standard settings on CPU-Z, which is compared to around 295 single-threaded and 1800 multithreaded on the overclocked FX 8350. In the 4.9-5.1 range. The Ryzen 3 2200G performs slightly better than the Ryzen 5 1400 for entry-level models. Your standard Ryzen options provide a 20% boost in single-thread performance, and faster DDR4 RAM can further enhance results. The FX8350 falls short, only matching the Ryzen 5 1400 closely at standard speeds and frequencies. For greater CPU capacity, you'll need to invest more for each MHz.
