Upgraded RAM ( to B-die) for Ryzen+ (2700) , worse stability

I am pretty annoyed that I just spent £200 on a pair of 'Ryzen Ready' Flare X 3200Mhz (B-Die) . Only to find that the XMP profile causes the system , to reset the bios on a 'cold boot' ( after turned off for some time)
After a few restarts the system will run just fine with the Flare X RAM ( stress tested)  , however I do not want to restart system on every cold boot .

Even if I reset to 'optimised defaults ,select the XMP , then restart ; the machine will still struggle every time from cold boot .

I have posted this in the GSkill forums , as I am convinced this is a RAM issue . Before the upgrade I was running 4 x 4GB 2666 Corsair vengeance ( OC to 3000Mhz) , just fine wihtout issue . Now I am struggling to understand why my alleged 'upgrade' will not remain stable with its intended settings . I have heard many stories that people can run the Flare X  3400 at CL 14 without issue .

Why is my system struggling with the XMP , I am really confused

X370 Upgraded RAM ( to B-die) for Ryzen+ (2700) , worse stability

Ok I will try again to explain a little more , and add some things I have since tried

Motherboard is a Gigabyte X370 Gaming 7 with latest F.32 bios ( time of writing )
CPU previously clocked up to 4.2 stable with Corsair Vengance LPX  ( 4 x 8GB 2666 rated )  XMP Timings and 2999  Mhz overclock - without issue , after a few bios up dates

New Flare X Ram Installed ( 2 x 8GB ) with XMP profile enabled , on a cold boot  causes the BIOS to reset the CPU speed to default
If I load the default speed x 32 @ 100Mhz ( 3200Mhz )  , the cold boot issue will dissapear and I can run the  3200Mhz at the advertised XMP speed .

I have tested increasing and decreasing all voltages , including :
Lowering and raising CPU 1.2- 1.5 V
Lowering and raising SOC 0.9 - 1.3 V
Lowering and Raising RAM 1.2 - 1.45V
Lowering and Raising related RAM voltages
Lowering and Raising LLC on both SOC and CPU

All of the different power configurations did not make the The cold boot issue go away  for  the following  CPU speeds
3.4 Ghz
3.6 Ghz
3.9 Ghz

Edit: I would like to add , that loosening the RAM timings does prevent the BIOS cold boot clock issue , however this is not a true solution as It defeats the object here .

I really dont understand how a 'more compatible' memory product , can result in much worse performance .  Could this be a board issue , should I upgrade to the X470 , or just return the RAM  and try a different set?

Ok some further tests and findings that have been made :

I built another Ryzen machine as a spare , the specs are as follows:
 Gigabyte AB350 Gaming 3 MB , 
Ryzen 1500X CPU
 Corsair PSU and WD Blue HDD

I put the B-Die flare X RAM inside this machine and guess what? Exactly the same issue , even with everything on default ( except XMP ) the machine will default the CPU to 3.2 with a bios error .

I have tried the sticks individually but have the same problem . I cant understand how both sticks can be faulty but , this is the only commonality with the issue amongst the two machines .

Bottom line here is this.  Is the RAM on the QVL for your board?  If not, unexpected behavior can result. 

Always safest to invest in a known commodity when it comes to RAM, especially if you want to OC or run with tight tolerances.

That's a very valid point  and no these sticks were not . However I updated my Bios from 23F to the latest V23 (August ) . No more cold boot errors , works every boot . Well done Gigabyte
