Just sharing another Cinebench R20 Result.
Managed to get:
4450Mhz core @ 4066Mhz MEM working with ~1.415V [LLC]-[EXTREME]
4400Mhz core @ 4066Mhz MEM required only ~1.375V [LLC]-[TURBO]
4450Mhz 4066Mhz MEM 5325points | 519points
I see others with 3800X posting better results, reaching much better speeds at the voltages I can stabilize. I have 'midrange' or a 'dud' 3800X from looking at the better results shared about online.
Gigabyte X570 AORUS XTREME, Ryzen 7 3800X 4.4Ghz, 4266/1900 MEM/FCLK, 184.108.40.206.76.tRFC 650 1T 1.600V
