5900x + Gigabyte X570 Pro wifi for RM3560 seems like a good deal?

Guys, i'm going to give up my Intel platform now as shown in my siggy below. The damn motherboard failed me twice and now 3rd time again with 3/4 RAM isn't able to detect my RAM overnight and now i'm stuck with single 16GB stick.

So now i make my mind to AMD Ryzen 9 5900x, can you guys recommend me a good motherboard for that?
Mobo can stretch until RM2k max, preferred <RM1500.

I will only change CPU and Mobo to AMD platform, the rest of the items on my siggy will be reused.

Requirement:
1. Good VRM cooling
2. Adequate OC capability (AMD is not OC friendly anyway)
3. Good reliability (not the damn Gigabyte anymore)

I have no experience in AMD world, please recommend me. SUPER URGENT.
Meanwhile i will do my own research as well, just that your suggestion can help me nail down much quicker.
Thanks alot.  

So you recommend B550 rather than X570.

Most B550 only have two M.2 slot, just wonder what option i have if i going to add 3rd drive?

As for X570, all come with chipset active cooling which is a big concern for me.
It seems in AMD camp the CPU is superior but chipset wise, hmm...  

Upgraded my CPU cooler to Corsair iCUE H150i Elite Capellix..

Temp about to settle down at 70'c under Prime95 stress test. However, the clocks speed for the 3700X only at 37xx mhz when im doing stress test. Is this consider normal? 

Close all the apps and any background apps before running it.

This is mine.

My RAM is DDR4-3800 C16

Place your bets people, at what price do you think ROG CROSSHAIR VIII EXTREME will start at:
A) RM2699
B) RM2799
C) RM2899
D) RM2999
E) RM4000
     

Whoever bought Ryzen CPU last year and redeemed game code for Far Cry 6 now you can activate the code.

Off topic.. lol

but all the fanboys can quickly go bid your number

Haiz, I ran into problem again on my system just under a year.

My PC shut off and restart randomly during normal operation.
The blackout is fast one, just a second before it alive, but it won't boot with Qcode 00 (not used code!!!) and QLED stuck at DRAM, and system not response to power button long press either. Have to kill the AC switch, then it will boot normally.
It will even reboot sometimes in BIOS setup page.

Try swap my RAM, still happen.
PBO disable, not fix.
Even run at optimised default also reboot.

I suspect now is due to either CPU or mobo, with highest suspicious on CPU.

Can you guys suggest a sensible way to further test out whether is CPU or mobo? I'm frustrating now as i just recover from a nightmare failure on my previous system before i switch to AMD platform, and the seemingly HW issue haunt me again.

I just want to avoid buy something new just to isolate the factor, but i won't know exactly the issue if i didn't do so, contradict, arggg

Where's your logic?

The problem isn't occur because of BIOS change previously. It worked fine for last 8 months until recently. So what to do with BIOS?
