So i did exactly what you said and here are the results so far.
45min in prime, hitting 93.1C max. This is with default settings > RAM XMP @ 2933 > Turbo Disabled https://imgur.com/a/wq7ZZge Still seems very hot. Ambient temp is 22C Idle temp 34C Edited by unseen0 - 01 May 2018 at 12:56am |

XMP cannot alter CPU voltage, this is something elese, please perform a UEFI reset to defaults after that, set your RAM speed, disable turbo and re-check.

My RAM runs at 1.20 volts, as Corsair specifies.

Thanks again for your reply.
I want to report back some findings. The RAM setting worked and everything went better for a bit. However, i noticed huge temperatures (92C) when playing a simple game. I took a glance at CPU-z and HWmonitor's readings. The CPU got 1.52V at some point, with turbo disabled! This is very high and the temperatures indicate it as well. I'm now downclocked to 3400 at which 1.25v seems to run and temps are fine (60c under load) I've read somewhere that XPM profiles can up voltages as well. But i really don't feel safe leaving it at 1.5+v. Stock settings > Turbo Disabled > XMP 2966 @ 1.35v for RAM > CPU @ 3600 @ 1.52V > 92C Stock settings > Turbo Disabled > XMP 2966 @ 1.35v for RAM > CPU @ 3400 @ 1.25V > 62C I have a strong feeling something is really off with whatever regulates voltage. |

Before switching from ASRock setting to AMD CBS just set your RAM to the desired speed then switch to AMD CBS, the speed/timings will transfer to AMD CBS, you can check that in CPU-Z
Cheers

Hi, thank you very much for your reply. It was very informative.
I did indeed find the Core Performance boost and disabled it. I'm stress testing now to see if the system is stable. This might be the key solution to my problem, so again thank you so much for your time! If you don't mind me asking. Is there a way to now up my RAM speed, as it's sitting on 2100mhz and i had it steadily on 2933mhz with the asrock XPM setting. I can't see any XMP settings no that AMD CBS is enabled. Thanks! |

You can disable Turbo the right way, and mantain adaptive frequency/voltage:
Switch "OC Mode" from "ASRock Setting" to "AMD CBS" then go to Advanced/AMD CBS/Zen Common Options/ and switch Core Performance Boost do disable, that will disable turbo but will leave all adaptive voltages and frequency scalings, you should also get a much lower max core voltage, from 1.4+ with turbo to 1.2+ without it. No you will not have lower default voltages, 2400G has a default voltage of between 1.395-1.450V, that 1.25V you see its because you disabled turbo. Keep in mind the 2400G can boost all cores to 3.9GHz because it uses Precision Boost 2.0 and mXFR like Ryzen 2nd gen, you need to treat it as such, its not a 1st gen Ryzen its a 2nd gen, it has so much better turbo scaling than the 1st gens, better memory controller, and better IPC, its a 2nd gen afterall PS 1.25V is not at all to high for 3.6GHz, when it boosts to 3.9-4GHz it will up its voltage up to 1.450V (depending on the silicone, they differ from batch to batch) and that's not high also its perfectly within AMD secifications. For it to boost to 3.9GHz on all cores and 4GHz on 2-3 of them you need a very good aircooler or watercooling, the 2400G has a declared TDP of 65W but the actual TDP and power draw when stressing both the CPU and GPU can go to about 120-140W, so you need to keep that in mind, the CPU will temperature throttle only at 95C, until then all the throttling you see its because of AGESA 1.0.0.1 power management bugs Dont compare Raven Ridge voltages with Summit Ridge voltages they are different cores, at any give frequency a 2400G will beat a 1500X (the CPU 2400G replaces) PS my 2400G at stock with watercooling scores about 435-440 points in CPU-Z benchmark, much higher than any 1st gen Ryzen CPU, and clock per clock faster than even the 2700X, and between 2260-2310 in multi threading, if I manually OC to 4150MHz on all cores I get about 466-470 in single threaded, and in multithreading @ 4150MHz I get almost 2520 points. So you cannot compare voltages, because they are different CPU's, Raven Ridge is AMD's fastest CPU regarding single threaded loads. A 2700X @ 4342MHz scores 478points, my 2400G @ 4149MHz scores 470 points. Just for the sake of it I ran a 4175MHz clock, it even beat the 2700X @ 4350 in single threading 2400G @ 4175 2700X @ 4350 Cheers

Hi,
I recently purchased a brand new system with an Asrock AB350M, a 2400G, 8G or 3200MHZ Corsair supported RAM and a 350W PSU. Installed, everything is well. However, whenever i run a game, i get crazy stuttering. Turns out, this is due to the 2400g throttling to it's turbo and disabling it solved that issue. The problem is, the only working way to disable turbo is to apply a 25mhz overclock from 3600 to 3625mhz. In order to do that, i have to manually fill in voltage. My CPU will not stabilize at anything below 1.275 volts, which is way to high for 3625mhz. Temperatures rise and my system will get close to thermal shutdown. Simply put, i can't run the combination stock, i can not disable turbo, i can not over/under clock/volt and i'm stuck with a system that simply does not work the way i intended it to. I'm running the latest BIOS ( i check back every day). It is said that the "agesa1002a" BIOS update would resolve this problem, but that's not available to my Asrock board. When can we expect a fix for this because i just can't use my system right now. And will a newer BIOS update stabilize my CPU at reasonable voltages when running at 3600mhz? 1.275V is ludicrous. I've seen people hit 1.075 volts on that frequency. |
