[SOLVED] Fatal1ty AB350 Gaming ITX/ac + RX Vega 56

UPDATE

1.Bumping RAMs to 2667 seem to do some magic,now i able to POST to desktop.Strangely enough,after successful GPU driver installation,everytime i boot i got this message box



To my knowledge,that might be earlier block chunks of memory are defect.Will do a DOS's Memtest 86 and Windows's Memtest 64 to see anything.And also,i will downgrade to Crimson 17.10.3 to see if that was a driver related.

2.Bad news (or actually a good one?).Both Memtest shows no error.Crimson 17.10.3 doesn't help at all,still got that annoying message box.While testing RAMs,i happened to test my NVMe storage,and good guess,all NAND blocks are green.And to pouring a salt in wound,my system now completely dead.Will try to swap CPU and motherboard and testing under Linux to see complete diagnostic.

3.Disaster.Now my card are dud,completely dead.Will RMA it on weekend and hope to see that girl again in 3 days.

4.Sorry forget to update.After had pretty long and rough assignment,I got my day off and i'm able to tweak again.I bought another ASRock ATX board and guess what,the system normal.What a prick.So Vega didn't go so well with Mini ITX board.Well,so much for the pain.

Thanks again folks,i've solved my problem

How about DRAM sticks?LOL!
64 gigs makes your GPU look like cheap ass crackers...

TBH i'm confused myself.At stock 2400 system won't boot at all except i do clear CMOS.Set stock,save,exit and BAM!I thought it might be DRAM problem,since i can only afford this sh*tty Hynix MFR Dual ranked,but everything normal at 2666.At higher frequencies such as 2800 or 2933 my system got stuck again though,so it's kinda weird i have to live with this 2666MHz RAM clocks.Maybe my system was a devil trophy?

Revert back to Crimson 17.10.3 doesn't do anything,still had the same message.But when i swap to my older card,there's no such thing.I'm beginning to think this Vega are defect.
