Ryzen 3600 All-Core Boost

[venomizer]

Hi,

 

Here are my specs:

 

Ryzen 3600

16GB (2x 8GB) Corsair 3000 CL15, OC'd to 3433 CL16

MSI B450 Tomahawk Max

Arctic Cooler 34 Duo

 

I can't seem to attain a very high all-core boost on the chip. Running Cinebench R20 this is what Ryzen Master shows.

 

It never goes above 3900MHz on any core. Temps seem fine to me and don't seem to affect the boost clock (here they sat at about 65C because my room is cold today, but on a hot day they can go up to 75C under load but the boost clock still maxes out at 3900MHz)

 

I feel like the chip is being undervolted as I believe it should go up to at least 1.35V and maybe as high as 1.45V? There seems to be enough overhead in the temps to allow this.

 

I have all PBO settings at Auto, but when I've tried playing around with them before it never seems to give me a higher all-core boost.

 

I just built a PC yesterday for my friend with these specs:

 

Ryzen 3600

16GB (2 x 8GB) Corsair 3200 CL15

Asrock B450M Pro4

CM Hyper 212

 

and first run on Cinebench his chip boosts straight up to 4120MHz all-core boost and gets a decent score of 3570 (mine is around 3430)

 

Any ideas? Did he just win the silicon lottery? Or is there something I can do to force the higher all-core boost without going full manual OC?

that's perfectly normal, out of the box it's 3.7/3.8 on all core so with pbo, there's 100mhz difference.

what?? 1.45 will destroy the cpu, and 1.35 will probably degrade the cpu slowly. 1.325/1.3 or below is relatively safe for zen 2.

new batches have better silicon, so im not really surprised. nothing wrong with the cpu for the most part.

Fair enough, I just wasn't expecting to see such a big change in boost performance between two identical chips

Under load you should not be seeing 1.35V+ at stock settings.

Maybe they got luckier with the chip.

Update your BIOS and chipset drivers and enable PBO. If that improves your performance by a bit, there you go.

i mean he could've won the lottery, but new batches do have better silicon so as i said im not really surprised.
