Hello, i recently buy a new Gigabyte H410M S2H v2 micro atx motherboard and when I'm in-game or when I do a stress test with OCCT on my intel i7-10700k CPU, it is throttling at 65 degrees and drops from 4.6 GHz to 1.5 GHz. I wonder if it's a power issue but I have a hard time finding out by myself.

If you have any idea of what it could be let me know, and if you have any questions don't hesitate to ask them.

Thanks

That motherboard is very low end and not meant for overclockable CPUs.
Go into bios and find the turbo power limits.
My guess is they are set very low.
It could also be the CPU Over Temperature Protection in the bios.
Turbo Power LimitsAllows you to set a power limit for CPU Turbo mode. When the CPU power consumption exceeds thespecified power limit, the CPU will automatically reduce the core frequency in order to reduce the power.Auto sets the power limit according to the CPU specifications. (Default: Auto)& Package Power Limit TDP (Watts) / Package Power Limit Time Allows you to set the power limit for CPU Turbomode and how long it takes to operate at the specified powerlimit. If the specified value is exceeded, the CPU will automatically reduce the core frequency in order toreduce the power. Auto sets the power limit according to the CPU specifications. This item is configurableonly when Turbo Power Limits is set to Enabled. (Default: Auto)

Unfortunately that board is not adequate for a 10700K. If you remove the power limits it will likely run the VRM's at extreme temperatures.

The only real solution is to get a better board, either a higher end B460 or B560 or a Z490 or Z590. Do you have a full system spec, including the model of components?

its weird cause before i buy it i checked the compatibility and its said its was good, so my problem is that my motherboard cant handle my processeur right ?

It's misleading, technically any LGA1200 board will run any 10th or 11th gen CPU. However not every board will run each CPU at it's full capacity. A Core i3 10100 for example can use a max of 90W, an i9 10900K can use up to 250W. Those two CPU's require very different boards to run at full capacity.

If it is set to 65 now you can take it all the way up to 100 degrees, that's safe.
Otherwise it could be the TAU setting, if it always slows down after about a minute of gaming then it's because it dials down to the lower power draw after TAU seconds, and at default that's 56sec

i can only set my turbo power limit to auto, activate/desactivate, and yes it always after a bit of time that my freeze happen ingame. What is TAU setting ? I cant find it on internet

Oh okay when im testing its seems like my cpu get 85w on average

That's the power limit, it would use much more if allowed to do so.

Intel CPU's have two main power states, PL1 and PL2. PL1 is the power the CPU will draw at it's base clock. In your case that's 125W at 3.8Ghz on all cores. PL2 is the max power used at the CPU's all core boost clock. In your case 229W at 4.7Ghz on all cores.

TAU is essentially a time limit on PL2, the default of which is 56 seconds. This means the CPU can run at 4.7Ghz on all cores for 56 seconds before returning to the PL1 state:

On more expensive motherboards the time limit TAU is often disabled by default so the CPU is able to run in the PL2 state permanently when under load. This is because they have much stronger VRM's to cope with the additional power draw. It should be noted that running in PL2 particularly on higher end CPU's requires significantly more cooling capability, a high end air cooler or at least a 240mm AIO liquid cooler is required.

ok got it, i have a good air cooler so there is no problem there but if i disable the settings to be able to be in PL2 all the time can the motherboard handle it ?

For reference I use a Z490 Mag Tomahawk with an i9 10850K. If you were to have a problem with temperatures, I found my 10850K responded quite well to undervolting. One of the advantages of the Z board is that you have full control over the CPU if you need to tweak anything.

Try running ThrottleStop.
https://www.techpowerup.com/download/techpowerup-throttlestop/

Open the Limit Reasons window and find out the reason why your computer is throttling. If the MHz drop that severely it is usually an issue with the voltage regulators. Look for VR CURRENT or VR THERMAL in Limit Reasons.

You can also turn on the Log File option so you have a record of your CPU performance. Do some proper troubleshooting before giving up on your motherboard. It might be something simple like one limit that the BIOS is not setting correctly.

Post some screenshots of ThrottleStop while you have this throttling problem so I can see your settings.

If you have a BD PROCHOT throttling problem, try clearing the BD PROCHOT check box on the main screen. This is a common issue.
