Over clock of a memory doesn't go well in SuperPi - 32M.
Is it impossible in B450?
Is it a problem that the memory voltage can be input only to 1.8V in particular? Are there also few items of the timing control?
You can't turn the current state and 3600Mhz.
Are there any special points in AMD?

try 3600Mhz 13-13-13-31, I managed 3600C12 on the Gigabyte B450 for the APU 2200G compo. I'll give the board a spin this week and show you some settings

Thank you for the information
Look forward to work with you again

K seems the IMC of my 1700X and 2400G are not good enough for +3600C12 so I switched to my daily rig and the 3800X.

Vdimm 1.75, VSOC 1.1 (+0.1) and 3600C12-12-12-36 is no problem.  This booted fine too on the Gigabyte B450, but the aforementioned CPUs couldn't handle it

 

 

Could well be that your particular CPU is the culprit and not the board... here's a score on that TUF board with loose timings but mems at 3800MHz

Just boot with loose timings, 3400 boot, reboot, up one multi and work your way up

Cheapaz Chips Round 1 At APU AMD 3000G
Everyone is turning at 3600

so get yours dialed in, like I said just boot at 3400 and check with memtweakit what the board sets for secondary and teritiary timings. If you see some timings way too tight versus mine at 3600Mhz loosen them…. like I tested 1.75Vdimm is plenty for 3600MHz C12... 

Question,: did you set maxmem in windows ? if above 3500MB it can get unstable with BDie mems, I usually run 3000MB

It doesn't start at all
