5900x and PBO2. Clock speeds

What clocks speeds are you all getting with a fine tuned PBO2 configuration?   most I can get is around 4.6 under cinabench testing.   Or, is it more about the faster clocks under the liter loads such as gaming?

 

Thank you.

That's about what I've seen on mine.

Since I am air cooled R23 prefers winter 😄 usually get 4650-4750 running R23. For lighter stuff she will boost though..

I've seen 4.8, 4.9 on mine, but I also found out recently certain RAM-related stability issues existed in the system. I'm thinking the RAM was somehow allowing the cores to boost further, but was unstable. Cooling is also key. Down for the moment waiting for more suitable parts.

Due to the above, I've likely revised posts <30 min old, and do not think as you do.

4.8-4.9 all-core during a Cinebench load?

I think I showed that from a CB R23 load. Unfortunately, the machine is down right now. Flaky RAM tricked me into RMA'ing the board before it really became clear. I also know now that the RAM I used wasn't QVL'd for the board, so it's going back together with a completely different RAM kit that IS QVL'd. So I have no idea whether it will still hit those speeds with different RAM. As I said, I kind of think the RAM was allowing the cores to boost a bit more, but in and of itself became unstable. I had some screenshots on the M.2 in that machine, hopefully I haven't deleted them so I can go back and check. However, it's irrelevant if what helps it hit that speed makes it unstable. 🤨

 

If I had known board, CPU, RAM and storage compatibility was such a jigsaw puzzle these days, I would have reconsidered even doing this build at all. 🙄

I checked Asus and G.Skill against each other as I was putting my rig together on Newegg in 2020. I even went so far as to check my nvme drives lol.. I just didn’t want to build a frustration box. A few people were like yeah qvl is dead it’ll just work. Well.. I have not had a problem at all with my rig. It’s been a smooth and stable experience.

My 5900x averages 4.5 ghz on R23 (just checked) with a peak of 5ghz on Cinebench R23 using PBO and negative curve.

AGESA 1206 and 1207 absolutely kills PBO performance. Hacking a max vcore of 1.5v down to a paltry 1.425v only helps those who cannot cool their cpu. My 5600X is the same, but with a max of 1.375 or something.. back to 1203 and life is good lol..

playing with some PBO2 settings I saw over 5GHZ for a moment. under a full, all core load, I do not see that.   I want this... (4:41 minute mark)
