A "state of the union" type update.
I've arrived at my "fully stable" daily driver OC settings. DRAM settings verified with 50 cycles of TestMem5 (1usmus_v3), 6 cycles of TestMem5 (extreme@anta777), and 48hrs OCCT (80%/Auto instruction set). PBO2 settings verified with more time in corecycler than an Intel fanboy would be willing to endure (SSE/AVX/AVX2/ALL FFTs), 24hrs looped CBR23 MT, 24hrs OCCT CPU stress (small/extreme/variable/auto/auto).
PBO2 PPT 300, TDC 160, EDC 225. +25MHz (5075), scalar x10. Curve optimizer cores/counts:
BIOS 3801 (AGESA 1203_C). Chipset drivers Rev. 4.03.03.431. 20⁰C ambient air / 22⁰C coolant / "daily driver" fan profile for the benchmarks below.
I've elected to forgo dynamic overclock switching for daily driving for the time being. As such, I left some performance on the table. While PBO2 alone forces one to choose between max single thread or max multithread or something in the middle (what I opted for), I believe it does a better job than I can at managing the CPU under all the conceivable loads that it might face. Were this a system intended for a specific task, I think DOC switching could be beneficial, but the user would need to keep a tight rein on the programs being launched.
Now it's time for me to make a decision. Do I spend the next month trying to improve on the DRAM settings that I plagiarized from J7, or do I jump ship, download More Power Tool, and have fun squeezing my GPU? I'm pretty confident as to which one will be the most fun, but I think long term I'd benefit more from learning the ins and outs of all the various DRAM settings and how they interact. I'll sleep on it for at least tonight.
