Instability with 4690k cache

So I increased my 4690k to 4.7ghz a couple of months ago. The APU pairs with an H100i and reached 80-81 degrees during games. Prime95 pushed it higher but Prime is just a lie anyway, so who cares. Recently, the clock became unstable, showing blue screens and crashes. I ran several stress tests to identify the faulty part. Using Aida64, I did a combined test covering CPU, FPU, cache, and RAM. It crashed after 2 minutes, so I repeated the test focusing only on the cache—again it crashed. To confirm, I tested without the cache and found no crashes. How can I fix this instability with my CPU's cache, or is this a hardware issue?

there is a concept known as CPU cache ratio—aim to reduce it below 40. you might also consider adjusting the cache voltage. if that doesn’t work, gradually decrease your clock speeds until stability is achieved.
