5950x seemingly not boosting?

[hormelspam23]

Hey, recently I posted about an unstable OC on my 5950x (https://linustechtips.com/topic/1427090-weird-behavior-with-5950x-overclock/), after which I cleared the AutoOC that AI Suite put in and just switched on PBO and +200 on Max CPU Boost Override in the BIOS. 

 

However, recently I noticed that the clock speeds of all the cores seem to be linked to each other and there's no longer core clock independence. All of the cores have exactly the same clock speed, which wasn't the case previously (and I don't believe should be happening):

Even single-core loads like doing single-core on Cinebench R23 also doesn't seem to have any effect on any one core by itself. It just seems that there isn't any boosting at all, despite PBO being on. 

 

Also, is all-core supposed to be only 3.6 GHz at full load? Shouldn't it be able to all-core boost to like 4.4 GHz? For reference I'm hitting it with an all-core load in the screenshot above, and temps are also only at 65 C, so it can't be thermal throttling. Thanks for the help in advance. 

 

System specs:

- 5950x

- 3090 FE

- Crosshair VIII Hero

- 4x8gb TridentZ Neo RGB 4000 MHz CL16 (clocked at 3733 right now)

- Kraken Z73

The rated base speed for the CPU is 3.4GHz and 3.6GHz is 200MHz above that. I don't think this is a coincidence - I think that somehow you've got it set to not boost, but PBO is overriding that and adding 200MHz to the base speed.

 

If you can't remember what settings you might have changed to cause this, I'd recommend making notes of any OC settings that you think are relevant, like your RAM's clock speed, and then doing a reset on your motherboard to put it at default settings. Then you can try again from scratch.
