BIOS Issues and Speed Reduction Techniques
BIOS Issues and Speed Reduction Techniques
It continues to happen once more. My computer has been operating smoothly for a while now, and thanks to everyone’s assistance during the previous troubleshooting, I’m counting on you to fix it again soon. Here’s what’s been happening:
I’ve encountered some problems after the last system update. The process involves turning the power button, switching it on and off, then restarting normally. That worked until I unplugged it and performed a CMOS reset. However, this has led to more complications than before.
When using BIOS optimized defaults, my PC boots fine. But if I adjust any BIOS settings to try underclocking or undervolting, it freezes. Changing these settings makes the system unbootable and forces a restore to the original configuration. This issue stems from frequent prompts for "System Restore" after each restart and blue screen occurrences following the splash screen.

Any support would be extremely valuable, thank you in advance.
When adjusting the voltage, the 9590 won't function properly. Avoid it.
Before, the main method to achieve stability was turning off C1E, C6, using a CPU around 4ghz (possibly too low) and adjusting the vcore to 1.4v (maybe not optimal).
It's an overclocked FX 8xxx built directly into the CPU package and launched as the first 5GHz processor. Lowering its power needs isn't possible. As a 220W CPU, it boasts the maximum default power consumption among nearly any desktop CPU.
I'd go for a replacement model instead of sticking with it. An 8xxx can be overclocked easily and would surpass its single-thread performance. With an 8350 now around 50quid, it's a smart move. Although you have options from the full FX lineup, a 6300 or 8730e might suit you better. It's not worth investing much since it's now outdated.
My 4350 can outperform the 9590 single-thread if I push it to 4.8GHz, which is pushing the limits of my system under normal conditions. However, I've run it at 4.9GHz with DDR3 2400 without major issues for everyday tasks.
With a reliable cooler handling an 8xxx, overclocking should be manageable. You'd have more flexibility in adjusting the overclocks. A 1.4 vCore is ideal for an FX, while 1.5v is the upper limit—though I've never pushed mine beyond 1.476.
Your cooler performs better than mine, so you shouldn't face issues when overclocking an 8xxx. The 6300 also offers a lower TDP at 95W, making it even easier to push.
Looking for stable BIOS settings for the 9590 seems frustrating; replacing it might be the simplest solution to avoid trouble.
It's challenging to compare since the 6300 is roughly the same price as the 8350. The 6300 seems more suitable for overclocking, though it operates at a lower clock speed on six cores compared to the 8350’s eight cores, which may offer better performance in multi-core tasks. Whether you prioritize extra cores for multithreading depends on your needs. I’m unsure about the exact overclocked bench results, as most sources only display the tested CPU’s overclocked version, like the 4350. From my view, the 8350 likely provides greater improvement for multithreaded workloads.
