[SOLVED] Cpu downclocking heavily under load (Ryzen 7 1800x Baseclock 3.30 GHz, 2.1 GHZ under load (stress test))

[SlimE_1]

Hello Everyone,

cpu: ryzen 7 1800x
mobo: x370-f
gpu: rx 480
ram: gskill ripjaws 2x8gb @3200mhz
500watt psu
cpu cooler: https://www.amazon.de/gp/product/B00PQ5LV1G/ref=ppx_yo_dt_b_asin_title_o05_s02?ie=UTF8&psc=1

No OC

idle runs 55 degrees @ 2.9ghz, under load it maxes out at 75degrees but it downclocks itself badly to 2.1 GHZ

Back in march it was running fine, but now it drastically has gotten a very bad performance

Guys please help me

if idle runs 55 then you might have a cooling problem , change the thermal paste ? Maybe Artic Silver 5 , also dont overapply it , only put a skinny line Like this

idle runs 50 degrees @ 2.9ghz, under load it maxes out at 75degrees but it downclocks itself badly to 2.8 GHZ

bios doesn't let me change any clock speeds / voltage , even if i go to manual it just grays out the options that appear

Agree with the LTT forum responses. You say you're getting a new cooler, so install that when it arrives and see how the temperatures are.

I built in my new cooler. Idle 35C, 65C under load. But the performance of my cpu is still poor, it's even worse than before. Is my cpu broken?

Agree with the user on LTT forums, use Userbenchmark with caution. One thing is clear though, your boost clock isn't working correctly for whatever reason. In fact, Userbenchmark seems to indicate your boost clock is lower than the base clock (however that works).

What other things have you got installed which can configure the CPU? Ryzen Master? Might be worth checking some settings on there if installed, otherwise it might be a BIOS issue (bit beyond me), or possibly power profiles in Windows.

We tried.. I am so done..
I posted a picture of the bench on LTT

Unplug the computer...remove the CMOS battery from the motherboard...wait 5 min. Put the battery back in (or better yet replace the battery with a new one) and reboot to motherboard defaults...apply the XMP profile for your RAM while leaving everything else at default. Check performance.

If you still have issues I would roll back to BIOS 4207 and see if the CPU performs correctly....you're running a first gen Ryzen chip and many newer BIOS have moved to support 2nd and 3rd gen Ryzen which might be causing issues.

It was BIOS related. MY bios was messed up and I had to flash a new version to it. Everything is fixed. Thank you all
