Thanks and Yes, I read your sharing about procodt, I set to 30ohms . The procedure is I use single memory boot up to enter bios change it, the ram boot voltage I also raised to 1.45v.
I may go to buy msi gaming x570 carbon wifi tomorrow then give a try again.
If you have a problem with booting and you are sure that it's related to RAM, try to set the timings manually. Remember that TRC is a multiple of TRFC. Rise TRFC adding to it TRC. For instance, if your TRC is 36 and TRFC is 468, sum 468 and 36 and set TRFC to 504.
Also, try to rise TRTP and TRWDWR by 2, or set it to auto.
Use Ryzen Calc to determine RTT. It has a huge impact on your ability to POST.
Also, try to rise the tRCDRD by +1, it will help with stability and will allow lower voltages.
Hope it will help since I managed to fix this issue. Let me know if it works for you, and if not, we'll dig further.
P.S.: 1.45V is awfully high and there is no need in that high voltage, especially for daily usage. While the RAM sticks don't care much about voltages below 1.9, you put too much strain on the memory controller. I'm running 3666 with very tight timing at only 1.36-1.365V without any single error. Too high voltage affects system stability in a bad way. If you raised the voltage by +0.1V and it's still doesn't POST - lower it back and look for the problem in another place.
