Okay, so I updated to modded BIOS 1801 (thanks Gonzo) which of course led me to retry my overclocks, and for the first time I think I've found an OCCT stable 4.5Ghz overclock. My question is, is there anything safety/degradation wise in the difference between these two overclock settings that would make you prefer the 4.4 Ghz over the 4.5 Ghz settings?
In the list below, I'm listing what I have set in the BIOS, followed in parenthesis what I actually get as the maximum for that value over the course of a 3 hour OCCT run.
Both settings are with my 2666 kit at XMP. I don't plan on ever OC'ing memory.
Both settings have cache set to min 30/max 30 adaptive auto. Actual cache voltage never gets as high as 1v, generally stays around 0.95v.
The super-stable 4.4 Ghz OC Settings:
Ratio/Clock: 44x100
LLC: 7
Total Adaptive Voltage: 1.25v (1.28v)
Input Voltage: 1.9v (1.88v)
Max CPU Package Temperature Spike in OCCT: 74c
Max single CPU core temp in OCCT: 70c
The 4.5 Ghz OC Settings currently under testing, but final stable settings should be very close to this:
Ratio/Clock: 45x100
LLC: Auto
Total Adaptive Voltage: 1.295v (1.33v)
Input Voltage: 1.92v (1.95v)
Max CPU Package Temperature Spike in OCCT: 80c
Max single CPU core temp in OCCT: 75c
The 4.5Ghz OCCT run is still going, but I've passed 2 hours at this point. I'll update if anything like max temp changes during the run. Note that this run is going with Steam minimized, Bitdefender active, and me working on the browser during the run.
Note when evaluating for safety/degradation that this IS fully adaptive, so it'll only be at the higher voltages under load. With my 4.4Ghz OC In Witcher 3 on 3D Vision in 1440p, CPU never seems to go over 62c so I don't expect it to ever reach 70c with the 4.5Ghz settings.
So. Thoughts? Opinions? Are those 4.5Ghz voltages/temps reasonable/safe for a 5930k for 24/7? Any suggestions on how I could increase stability? For the 4.5Ghz run I have CPU Power Phase Control and both DRAM Power Phase Control settings set to Optimized, it seems to have improved stability. The CPU/VRM Spectrum settings are auto/disabled, I thought enabling those were helpful for a bit but, no, not in the long run.
