I've still been unable to get more than a single 8GB stick of B-die to boot. Even 2x8GB B-die will power off at Dr Debug code 36.

boot with the 8gb
change ram voltage to 1.4 volts
save exit reboot
save and exit again then fit one 32gb stick to slot a2 and try it


I've tried this several different ways, no success yet. I don't know what to do at this point... I've ordered a B550 and will see how that goes.

I thought datonyb's advice of 1.4v would have nailed it to success.

if still not, then make sure the single 8GB stick voltages are
Dram 1.4V or more, all the all up to 1.45V is safe, especially just to test boot.
then

don't load XMP yet, don't run 2666mhz, not even 2133mhz, instead try 1866mhz, or whatever lowest possible.

SOC_V 1.2v this is default when high speed ram in used, but when 2133mhz is in used, then SOC_V drops of 0.8V only, This is why after swap in 32GB sticks, completely not enough to boot. Use 1.2V for SOC like the trick advice by datonyb.

CLDO_VDDP default is 900mv = 0.9V, but it can go easily to 1.05V, so try this also, this is the infinity fabric high way voltage.

32GB sticks may require more voltages.

finally try bios 6.20A or 6.20B, they are not out for no reason I think.

I had significant stability problem with 6.20, for two whole months I rejected to use 6.20A, but once upgraded, very stable, and very easy to overclock ram. I've got 3600 fast A0 PCB 1.38v, and 3733 safe 1.4V, all as per 1usmus calculator.

Finally resolved this. I tried a number of different BIOS and none made any difference (currently on 6.32). What solved it for me, amazingly enough, was to install the RGBLED tool and (manually from cmdline) upgrade the RGB firmware.

My theory is the RGB firmware is also some sort of embedded controller firmware responsible for some sort of boot sequencing.

Everything seems to be running great now; 4x32GB ECC no problems.

I registered just to say thank you all.

I went from a 2700x to a 3950x and couldn't boot. Was in the error code loop. The magic for me was removing the second video card. I started with removing all but 1 stick of ram and when that didn't work, pulled the 2nd card. After that battery pull and replace... viola. I put the card back in, then the other 3 sticks of memory and was good after that.

Thanks again!
