(Apologies for photos of screen. Laziness on my part)
Had my system clocked at 5ghz 1.4vcore with 4.8ghz cache for a couple of years when I was suddenly hit by instability. No crashing or WHEA but the system would micro freeze constantly making it impossible to do anything. My ram kit is G.Skill 32GB Trident Z Royal Elite 3600mhz (Samsung b-die @ stock XMP), all packaged on an ASUS ROG Strix Z490-G Gaming WiFi which has been a stellar board.
I disabled my OC and left it for a while. Well now I’ve had another crack at a more modest OC as follows:
-4.8ghz core
-4.8ghz cache
-1.35v vcore
-1.2v VCCSA
-1.15 VCCIO
-XMP II (Ram manufacturers specification)
-Trfc 320 (down from 631)
-Power limits, c-states etc. all disabled
-LLC4
-MCE on
-0 AVX offset
-Stress tested using Karhu memtest, intelburnin, y-cruncher, Tm5 with anta777 extreme profile, prime 95 small fft, OCCT SSE/AVX memory test.
-Real world tested some CPU heavy games in CPU bound scenarios (TLOU1, Cyberpunk, GTA5), unzipping large files, opening multiple heavy applications at once
-Installed fan directly on the RAM modules to keep temps under 40 degrees during stress testing.
I’m a little bit weary about pushing past my current vcore as I’m worried that running 1.4v for a couple of years caused minor degradation. Please let me know your thoughts, I have a small amount of OC knowledge but am not sure what I can or can’t do from here. Google search results are all over the shop.
Am I at a safe limit here? Or is there plenty more juice to squeeze? Would it be worth dropping the cache to 4.7-4.6 to be able to hit 5ghz all core?

Your ram could go way higher, like at least 4400mhz since it’s a good b die. This scales really well with voltage so you can go up to 1.55v without any issue for degradation and that would allow you to push really tight timings
