Bought FlareX 2x8GB 3200mhz cl14. 2x ram is working at native specs (2400 cl16 1.2v dual channel) fine, both sticks are definitely 3200 flare x ( checked backside) and I can load single stick at xmp, but not both at the same time and while 1st one alone works at xmp 2nd one wont post at all. Is one stick maybe defective?
PC Specs:
Ryzen 5 1600
GA-AB350M-Gaming 3
Thermaltake TR2 Challenger 500W
G.SKILL F4-3200C14D-16GFX
GTX 1070ti

Update: Checked the RAM in CPU-Z to make sure the second module wasnt a lower spec one put in the wrong box and they are both the same. Also I am on latest BIOS, all slots have been tested with working stick and they are not the issue and the memory is from the QVL list for the MB so compatibility isnt the issue.

Yes they are installed in the right slots, I have tried them together in different slots and individually in different slots. I am very certain it is not an issue with slots.

Yeah I did a BIOS update last week but that never helped. I'll run the memtest and let you know the results.
 
with gaming ram to get those higher speeds you may have to add some voltage to the ram slots. if not the mb may not post. another issue is the ram amd or intel ram. some intel ram may post and work at slower speeds. (there been posting online that some 3200 ram on amd mb wont go faster then 2900 speed. if there a setting for xmp profile ot run slower then max speed see if the ram will post.

I have tried increasing the voltage and at different speeds, no speed above 2400mhz works neither does the increasing voltage
