Throttle Stop doesnt show errors anymore when undervolting cpu core + same consumed watts under load ( Ts Bench )

[Amiine]

Hello,
I want to know if there is a problem with my throttle stop configuration, I feel like that the program don't take in consideration my CPU core undervolting, it shows all the time +84W when a launch the Ts benchmark, on the other side it shows errors when I go under -109 in CPU cache (wich normal)

84W

I do not know if that is good or bad for a 9700K. Power consumption will vary from one 9700K to another 9700K.

ThrottleStop seems to be working correctly. The FIVR window shows that you lowered the turbo ratios to 44. Why did you do that? A slower CPU decreases power consumption. Push the Defaults button in the FIVR window so the CPU can run at the speed that Intel designed your CPU to run at.

Your undervolt is working. If you need to be convinced of this, run the TS Bench with the core and cache set to an offset of +0 mV. Push Apply and check the FIVR monitoring table to make sure that your core and cache offset voltages have been reset to +0.0000. Compare power consumption of this test to the same test when you are undervolting. Make sure the CPU is running at the exact same speed in both tests for a fair comparison. Post screenshots of these two tests if you are not seeing a difference in power consumption during the two tests.

The TS Bench showing errors when you undervolt too much confirms that your undervolt must be working. Everything looks good. I always recommend using the latest version of ThrottleStop which is 9.6.

Hello again, I prefer to reduce the CPU speed + a lower temperature; I think that 44 does the job for now because I try to find the perfect spot (speed/heat).

I'v

e tried the test with the same values in the previous screenshots today, and surprise, throttle stop shows errors during the Ts bench. and I didn't get why.

that's my logs during the tests

When you undervolt a CPU too much, it will not be 100% stable. It might run error free yesterday and the exact same settings might cause an error today. If I see any errors in the TS Bench test, I would always increase the voltage (reduce your undervolt). Even 1 Error is one error too many for me. That is why Intel uses extra voltage. To prevent any errors.

Thank you sir, that's the answer that I wanted to hear to feed my curiosity (I wanted to know if errors are tolerable or not). Now I'm going to try to find the best numbers without errors. Are my settings on the screenshots okay? (not the undervolt values)


or there is something to change to optimize (ex: speedshift value, power limits, cache ratio, etc.).


And for the speedshift value, is there harm to the CPU if I let the value at 0 all the time?


thank you for your help sir

I always use the Windows High Performance power plan which automatically sets Speed Shift EPP to a value of 0. I never check the Speed Shift EPP box on the main screen of ThrottleStop. There is no need to check this box or to set your own EPP value. You can run your CPU however you like without hurting it. If you want the CPU to slow down when it is lightly loaded, switch to the Windows Balanced power plan. When the low power C states are enabled in the BIOS, switching between these power plans makes very little difference to power consumption. The C states are designed to automatically lower the CPU speed internally when cores are not being used.

The ThrottleStop TS Bench is just one test. Any errors in any test or any blue screens is usually a good sign that a CPU needs more voltage. Some users think that an error or two in the TS Bench is no big deal and they might be right. Running CPUs on the very edge of stability is not for me. When undervolting, I always add a little extra voltage just so I can be confident that my CPU is running as close to 100% stable as possible.

You can use ThrottleStop to increase the cache ratio. Low temperatures and low power consumption seem more important to you than maximum performance so I would leave the cache ratio as is. A higher cache ratio might need an increase in the CPU voltage to be stable.
