The CPU can jump several tens of degrees in seconds, but even will full CPU and GPU load 95°C after 30 seconds for me appears a bit too high for a Wraith Stealth with 2400G, unless you live at 30++ C ambient? What's ambient and what's idle temp at normal fanspeed?First post here - bear with me
Has anyone figured out how to get cTDP to work under AMD CBS settings?
My 2400g goes to 95C during a [email protected] BOINC load in less than 30 seconds. I'm using a shroud-less wraith stealth at 2000rpm. I've triple checked my MX-4 paste application and it seems fine.
My first thought was to check if the board had cTDP settings in the BIOS. It seems to have them under the CBS settings but changing the setting doesn't seem to actually do anything.
I've set it to both "commercial/consumer" (why are there two?) 35w & 45w (from the default 65w) and both don't appear to do anything. HWinfo reports up to 140W CPU+SoC power at full load regardless of the cTDP setting. It's driving me nuts. The computer is thermal throttling. Any advice? If I can't figure this out I'm going to have to return the 2400g.
And the results from fiddling with P-States at https://smallformfactor.net/forum/threads/sffn-asrocks-deskmini-a300-finally.10553/post-147902
- Set cTDP to 45W/35W and / or disable boost. With a 2200G on CPUz CPU Stress i got the following readings from Ryzen Master:
- cTDP Auto (65W), Core Performance Boost Enabled -> 3700MHz All Core, 50W CPU Core, 1.3625V CPU Core
- cTDP 45W, Core Performance Boost Enabled -> 3650MHz All Core, 46W CPU Core, 1.3125V - 1.33125V CPU Core
- cTDP Auto (65W), Core Performance Boost Disabled -> 3500MHz All Core, 37W CPU Core, 1.20625V - 1.2125V CPU Core
- The TDP Setting can be found in Advanced -> AMD CBS -> NBIO Common Options -> System Configuration. BIOS P3.40 has the wattages in "Consumer" and "Commercial" configurations, not sure what that does. I have tested on P1.20 which only has one config per wattage.
- Core Performance Boost is found in Advanced -> AMD CBS -> Zen Common Options -> Core Performance Boost
I really like this! One question though, why did you install the HP-400 with the heatpipe bends facing the back? Does it not fit the other way around, that way the fins should be almost exactly under the fan grille?little bit google translated cause my english poor )
Thats my cooling solution.

Yes. Overclocking does not work in any BIOS. Neither does overclocking via Ryzen Master, nor via Ryzen NB SMU Tool https://github.com/FlyGoat/ryzen_nb_smu or any of the tools derived from it. Underclocking works fine. All info is in this thread. While people, me included, are willing to pay for a mod for OC and other features, this has unfortunately not yielded a workaround: https://smallformfactor.net/forum/threads/group-buy-crowdfunded-modded-bios-for-the-asrock-a300m-deskmini-a300.10567/Does anyone tried to use some previous version the a300 bios to overclock the 3400g?
The system should regulate GPU/CPU power allocations within TDP automatically, and unless the GPU is being stressed somehow its power draw will be negligible - a couple of watts at most. Undervolting is a far better strategy to extracting maximum performance out of the system, as that will lower power draw at a given clock speed and thus allow the CPU to either boost higher or for longer, or run cooler overall. If the GPU is being taxed to a sufficient degree for it to take power away from the CPU then either it is doing something useful (in which case underclocking it or similar will harm performance) or something is loading the system unnecessarily and a better strategy would be identifying the source of the workload and disabling/closing/uninstalling the offending application.Never used overclocking settings.
I am not a gamer.
Using this machine for stock market research.
And sometimes watch videos (series, onlinechess, ...)
I have 2400G.
I want strong CPU and weak GPU.
Is it possible that i can reduce GPU, to safe some wattage ?
But the CPU should stay at maximum !
Or is the GPU already very economical, at idle, that I will not achieve any gain ?
Maybe someone can give me a little guide, so I do not have to try hundreds of settings
Thank you !
Nice thinking there d^_^b - I like where this is going.
