Why i say that is because for ryzen 3000 highest factor in its boosting algorithm is temperature, keeping it under 75c is key to get best performance while keeping it stock for exaple stock cooler + stock 3800x cinebench r20 scores 4935, noctua nh u12a +3800x stock 5000+ . A stock cooler i think it does a decent job on the 65w cpus , but when the big boys hit the room , 3800x and 3900x they need more .just my 2 cents on the matter. Besides 80+c i dont think is good for any pc part on the long term, And overclocking aint worth it if you can run it cold enough stock, it will boost just great so that aint worth to overclock it and deal with instability

I run a 3800X on a Mortar with and H80i and I don't get to 5000 point. Just shy at 4980.. just like that 5000 points? I think it also has something to do with how well binned the chip is. Or maybe my motherboard won't boost far enough? I have just PBO on. No enhanced settings.

I found that manual overclocking helps a lot seen that you are able to see how far your cpu can go at a certain vcore. Having done all this I was trying top test the whole issue of performance loss when using a negative vcore offset. Well there is no truth to it, if you know your cpu. Before I post the results I'd like to put things into perspective. My cpu is all core stable at 4.267ghz using 1.2375vcore, and it is also stable at 4.317ghz using 1.3vcore, so I went the high negative of-set route, at first -0.125vcore the -0.1375vcore. First result however is with PBO max and vcore auto, second with -0.1250 vcore off-set and third with.
-0.1375vcore off-set. CPU all core at Auto vcore was hovering 100.4 x 4.15 and 4.25 and with the negative off-set 42 and 41.75.

because everyone complains that they have some kind of problems. So I wanted to find out. I turned on the XMP profile in BIOS and manually set the voltage to 1.35
If you like, you can try out the Ryzen Dram Calculator from 1usmus. It's a very nice tool to set up your RAM or OC with it
