Finally starting to be satisfied with the daily settings and stability. My potato 9800x3d (109sp) seems to have a pretty good IMC. 8000cl36 GDM disabled appears stable. It can do -18 CO, but can't hold a steady 5225mhz in C23 even with the CO.
If I enable PBO +200 vcore goes well above 1.3v, with spikes up to 1.38v. I'm not comfortable with that, so keeping it at stock.
I have primarily aimed for a comfy UV/temperature controlled daily setup, with Noctua fans spinning at 33% regardless of load. It's not a cool system by any means, only just cool enought to keep RAM sticks under 52c. Silence above all.
The system was pushed to unstable OC levels to see what it can do, and it managed top 2-4% scores for most 3d mark benchmarks for same hardware, but would crash in most games at that point. With a better 9800x3d I think it could push top100 scores.
