I flashed back a older Bios and there it doesn't happen. But it happens again, once I flashed 0075 again. Also might be related: One time my keyboard didn't work at all under windows (drivers where there). Unplugging and plugging in didn't help, also Windows showed new device ready. Reboot didn't help either only using a different USB port. Also Bios 0075

Worst of all: My previous 5 Hour Prime95 stable RAM overclock now produces errors after only 5 Minutes. Flashing back makes it stable again. In fact I tried now 2 Days to get the RAM stable again but 0 luck. Some settings even seem to be unstable at random. Sometimes they work for 2 Hours, next reboot only 5 Minutes. Also booting is now much more of a luck thing. Sometimes 0075 resets the settings without notice, sometimes it boots, sometimes it hangs with Code 15. All random.
0075 doesn't fix RAM OC problems it introduced a lot more......
My CPU: 3900X and 64GB B-DIE RAM

PS: 0075 might have made the CPU unstable instead of the RAM. Have to rule that out first. CPU has no overclock through.
Do you have a negative offset applied to the vcore? If so, remove it and test.
Is it unstable with optimised default BIOS?

Ne01 OnnA 5168pts Multi in CineBench 20
at 4300MHz 1.33v | 1900FLCK | 3800MHz CL16 1T

Note:
Can render even with 1.284V but score is lower, best is to have 1.308v up to 1.35v (1.33v is Fine)
Im using Offset at -0.006250
LLT CPU 4 & SOC 3 is used.

Temps up to 70deg.

abso What voltages does the board apply with the new updates? Out of the box I saw up to 1.5V Vcore with my 3700X. This is why I decided to go all-core OC to 4.3Ghz and 1.3V. Also do you get the 4.4Ghz reliable in modern games or just when running CB single core?

Do you use PBO scaler settings? If so what level?

hmm it is weird though, how everyone could undervolt as much as they wanted on previous biosses and everything would be fine, the cpu would just clockstretch to compensate.

In some threads stuff like T and Daisy Chain is mentioned but not sure what it means. I got 2x8GB Ballistix Sports (E-Dies) running at 3800Mhz CL16 right now, CPU is a 3700X.
T-Topology means that all signal paths to all four dimms is even and same lenght to the CPU. All four stick should OC same if their quality is same.

It could be to do with how the new agesa of smu reacts with voltages and that reducing voltage to lower than what the cpu asks for introduces instability.
people are reporting all kinds of instability on the rog forums and here: random shutdows, bsods, game crashes.
