So i just got my 2700x and i have been keeping an eye on temps and clocks, it will boost to 4.3ghz in general day to day activities but if i load cinebench or something cpu intensive then it wont boost past 3974mhz, is there a reason for this? My cpu never goes above 55-60c, i just ran the benchmark and it was 48c at 100% utilisation, doesnt seem too hot for turbo?

Ryzen turbo boost - why does it not go full speed when being taxed?

Which board? Because if remember correctly for benching, some motherboards have special setting to activate.
Its the Gigabyte Aorus gaming 7 X470, its not because i want to get good benching scores but it seems weird i get over 4ghz in normal use but when my cpu is really taxed its much lower.
Btw how's the board with ram overclocking?
Does it is have offset voltage settings, does also allows PBO changes etc?
Also have a look here to see if some setting is not what it should to achieve what you want
https://overclocking.guide/gigabyte-x470-overclocking-guide/
But don't disappear if it works, need to know if it did worked
I honestly dont know what PBO changes are but straight away the 3600mhz XMP profile worked flawlessly and it seems im able to increase frequency manually if wanted.
I was looking at the overclocking guide but it seems its a lot extra heat for not a lot of performance boost, going to up to 4.3ghz only increased the cinebench score by such a tiny amount. Im not sure i want to overclock since i like to keep my computer nice and cool and this chip is already a toasty one, idle it sits between 30 and 45c and then load about 50c to 60c, its a LOT hotter than my last intel chip.

Have you activated the Precision Boost override? As that is the one that gives more of the performance when relying on XFR do to the job.
I believe on the AMD overclocking tool has that option, otherwise activate it on your motherboard.
See what I am talking about here.
I thought the standard all core boost for the 2700x was around 4Ghz anyway, so if you haven't touched any overclocking settings, then that's about right. 4.3Ghz was 1 to 2 core boost, which steadily drops as more cores are loaded to about 4Ghz
Ok in ryzen master i enabled the precision boost overdrive and it is giving me 4.4ghz on single cores so a little bit of an increase but again when its got all 16 cores at 100% im stuck at 3974mhz, i think maybe its meant to be that way, im sure i remember reading about how single cores can be boosted much higher than all 8.
You can go manual overclock after that. But at standard XFR thats correct
Look here

Crack the fan speed to 100% and give a try without changing anything else.
What cooler you are using btw?
I have a Noctua D14 so its a big beefy cooler, only have 1 fan on it at the moment but im getting Noctua to send me some new clips as i misplaced them and then i can go with all 3 fans. Im not sure i want to overclock manually because the CPU is an absolute beast as is, i dont think overclocking would help me much at all but i enjoy the turboboost!You can go manual overclock after that. But at standard XFR thats correct

Are you using the latest motherboard bios?
Yep i installed the latest bios last night, from what i gather this is perfectly normal, all 8 cores wont boost as high as individual cores.
They boost depending the cooling. The better the cooling the better the boosting.
Same applies to Vega 64 also. You would be surprised the auto clocking at 176W and 234W on that GPU if you watercool it and keep temps bellow 30C. (easy with a Predator 360).
Well i have killer cooling, when max is barely hitting 60c i dont see why it wouldnt boost to the max, im getting 4.7ghz on single core boost, is that decent?

Sounds normal.
That's how my 2700x behaves. I see spikes to about 4.1Ghz but all cores are similar to your 3974Mhz speeds.

Watching the video above has made me think of something.
The fact that when you enable DOCP and it manually sets the SOC to 1.1v, have we potentially handicapped the CPU's PBO in that one variable by saying do not exceed this value?
It might be theoretically better then leave it on auto so the mobo/cpu can exceed 1.1v given certain situations. But then this then leaves you with potentially unstable ram if you push the DRAM clock speed.
Am I right in my assumption or wrong?

Please do a single thread Cinebench run.
Ok so cinebench is 1770 and single core is 175 but again when running the single core not a single core went above 4.2ghz, when im browsing and doing normal stuff im watching my core speeds in CPUID and thats where i will see it creep, i get regularly 4.5ghz and then occasionally 4.7ghz but it never seems to be for long.
