RAM overclocking

[neanterthal]

So I recently OC'ed my balistix 2400Mhz, Dual rank, B-die, SPD 16-16-16-39-55 @ 1.2V
To -> 2800 Mhz 16-17-17-17-34-62 @ 1.35V (as recommended by Ryzen Dram calculator.)
This OC worries me as it has rendered my Cpu OCs unstable. I ran 3 test passes on Memtest86 so I doubt the memory is a problem.
Could anyone advise on what I should look into or do?
Mem OC done on Bios, CPU OC done on ryzen master. LLC has been adjusted to mode 3 (mobo: MSI B450 ITX) to accurately reflect voltages set by ryzen master.
Setup
R 5 1600X
MSI B450 ITX
Corsair SF750 Platinum
Axle GTX 1070
Samsung 860 evo 500Gb
Previous stable cpu OCs (tested with prime95 small ffts)
3.8Ghz @ 1.3V
3.9Ghz @ 1.3375V

Try increase SOC voltage. Not familiar with the board or the platform at all now, but you could try SOC voltage 1.2, maybe it'll help.
Are you sure that's B-die?
Also, rather OC from BIOS only, using two different utilities is inviting problems and needlessly complicating your OC.

As Gouhan stated above rather do all overclocking from the Bios. In all honesty I do not use Ryzen Master as everything given by Ryzen Master appears to be averaged out. Furthermore, as per what Gouhan suggested, increasing the SOC voltage to 1.2v may help. I also found that LLC set in bios actually causes vdroop and when left on Auto there is basically no vdroop.

Thank you for the advice. I only needed to up SOC to 1.075v to get the memory stable at my 3.8Ghz OC but the 3.9Ghz OC is still giving me problems.
Yes I am sure it's B-die. Just Micron B-die. Unfortunately not samsung B-die.
