So having built my first ryzem system a asrock b450 pro 4 and ryzen 2600X chip, I like many others am amazed at the value for money vs intel and the superior turbo clock system.
However I do note that if CPB is disabled, the voltage is a very low 1.08v under full load and cpu temp maxes out at 44C.
The extra 400-600mhz from turbo pumps out an extra 0.3v and temps go up 20C under load. So power and heat efficiency goes out the window. Although the chip still remains within TDP limits tho so its not like its using crazy power or anything.
I have noticed tho there seens to be a possibly happy medium I would be happy with so.
1.08v 3600mhz
1.30v 4050mhz <-- this one
1.35v 4150mhz
1.39v 4250mhz <- only ever seen this on a 2 core load but the higher voltage is applied to all cores.
I pretty much never see a load that will use 3.6ghz clocks, its basically either idle or in turbo clocks. The cpu scheduler ramps up clock speeds very rapidly so even low cpu loads utilise turbo clocks.
Also I am glad amd have min clocks of 2.2ghz, the min of 800mhz on intel cpu's is way too low and affects responsiveness of apps too much.
I would love for this to be tunable somehow, I know on intel e.g. on the balanced windows power profile, the cpu needs higher cpu usage to ramp up, in full performance profile it behaves like the ryzen where opening notepad will put you in turbo clocks, but on balanced you actually need to put moderate load on the system which I prefer, however on the balanced profile ryzen is uber sensitive and as a result there is a lot of voltage spikes up to 1.35v and beyond.
Setting a 4ghz manual clock in the bios with something like 1.3v I am kinda considering but its like 10-20% wantng to do it I feel the auto o/c is pretty damn good, I would prefer instead to somehow adjust the behaviour so it needs more cpu load before using turbo clocks if thats possible is that what p-state tuning does?
