14900kf. For the past 1.5/2 years since this boards came out I’ve been rocking bio’s version 2.04 and was stuck at 8000mhz. I could get 8200 to run for 20+ hours in Karhu however I’d reboot and run the test again and error out instantly. So long story short couldn’t get past 8000 no matter what voltage combo I tried. A few days ago decided fuck it I’ll update to the latest one and the improved memory stability was insane. Able to get 8400mhz stable instantly. And after a day or two messing with timings was able to get this profile stable in Karhu and VST. Aidia tells me these two profiles have the exact same latency.. which I find hard to believe. Honestly think 8533 with some fafo is doable and possibly 8600. But upgrade your bios if you have this board. Be careful it sets the AC load line to .74 which causes your cpu to pull a shit ton of power. I set it back down to .50 and DC back to 1.10 and it’s back to normal.
