AMD Ryzen 7 9800X3D

Currently running my 9800X3D on a push/pull 280mm rad setup and it's great seeing temps lower at idle - but at full load the sustained boost is really impressive. I never struggled cooling it (with either a 240mm AIO or tower air cooler) - but giving it a lot of overhead really seems to benefit it keeping at the higher boost clocks.
 
One year later and my 9800x3d just died. Game froze, rebooted aystem and it never booted again. 00 error, no post. Checked for burn marks, all clear. Tried another 9800x3d from my mates pc and it all works. Filled ocuk rma process, 48h later still no response. Fingers crossed will get it replaced before xmas holidays. Motherboard is x870e Nova on 3.5 bios

Happened to me last week. Already got the replacement cpu but the retailer said nothing wrong with mobo and just sent that crap back to me. I bought a gigabyte x870 board and will use that now. asrock can go to hell. I will try and contact Asrock and get a refund or something
 
Yeah, it's not looking great. Still no issues my side and I do wonder whether any of the BIOS settings I made to mitigate this have had any effect. specifically lowering VDDCR_CPU = -50mv and VSOC = 1.18.

I guess time will tell

I understand every 9800x3d is somewhat different.. I run a stock 9800x3d and not overclocked I think I understand this negative pbo and 200mhz boost and kind of know where they are in the bios is they a safe overclock with a little gain in games I can do without stress testing the **** out of my system? I have ram set 6000 cl30 on standard expo timings.

-10 or -15 should be safe

I have mine at -15.

Set it to -15 and if you get any crashes in games just set it to -10 and you should be good.

So set -15 negative all core pbo and no other settings like voltage or core clock?

Yup, exactly that. I think you could push it further tbh, I started at -30 and worked down from there.

-25 works nicely on mine and doesn't crash, mate of mine has said his sits happily at -20.

What about core clocks + 200mhz not bothered with any of that? just literally negative all core pbo no other settings? Seems too easy :D
