Dear Gigabyte and forum users,
This is more or less a report of my very odd findings regarding the boostclocks in F40 vs F41c bios.
First of all, I bought a 3800x to pair it with a X470 Gaming 7 and a nice set of B-Die 3600c17. The motherboard came with The Zen 2 Supporting F40 bios with AGESA 1002. To my surprise and in contrary to the findings of reviewers and overclockers like 'Der 8auer', Gamers Nexus e.a.' the reported boostclocks surpassed the 'advertized' 4500Mhz boostclocks with ease! More rule than exception: 4550Mhz reported in HWinfo64. THIS WAS OUT OF THE BOX!! In short, i was a very happy man for sure! *The B-die did a great job too by the way.. 3733 c17 to start off with no problem at all (stock volt for now.)
I knew there was a newer bios, so after installing F41c i started testing again. To my disappointment the magical 4550Mhz boostclocks were gone. I did nothing else than Optimized defaults -> flashing -> Optimized defaults -> setup Ram + timings -> Boot again... Not a Khz above 4400Mhz..
So the new bios hampered the chip by a 150Mhz? In my case is a repeatable issue. (or is it a 'feature'
) Of course i reverted the flashing sequence and am now back @ bios 1.40. And my healthy 4550Mhz boostclocks are back. What is going on here? Obviously the F40 bios id doing the better job, but apparently nobody knows? And what are my disadvantages with not having AGESA 1003AB?
Let me state i'm quite an experienced PC user and overclocker, and testing (my own) hardware extensively is my second nature. My knowledge and understanding of the basics of PC hardware is fine, so any indepth comment/reply is welcome. (tho im a former Intel user, i understand the basics of Ryzen OC (PBO/XFR) enough)
