Hi All,
I have spent the last few days searching these forums looking for answers and have found a bunch of great info. But i'm still a little perplexed about the problem that I am having and hope you all can shed some light on it. This is my first build with a Ryzen processor so im pretty noobish here.....
First things first, my computer build:
CPU: Ryzen 3950x
Cooler: Noctua NH-D15 (using both fans, ARCTIC MX-4 Thermal Paste)
Motherboard: Gigabyte Ultra X570
Memory: G.Skill Trident Z Neo 32gb, F4-3600C16D-32GTZNC
Case: Fractal Design Define R6 (7 fans total pushing air from front to back and bottom to top)
PSU: Corsair RM850x
Current Tweaking:
-I have the latest BIOS and chipset drivers installed.
-XMP is on with memory at 3600
-PBO is off and LLC is High
-Vcore set to 1.325
Im not trying to set world records with this build/setup. Just wanted to futureproof myself for gaming as I only upgrade every 6-8 years or so. However, I always like to run Prime95 just to check thermals and make sure everything is ok. So I ran 3 tests on Prime95 and have attached screenshots of each. 1) Blend test, AVX off running 16 threads. 2) Small FFT, AVX off running 16 threads 3) Small FFT, AVX off running 32 threads. All screenshots taken within the first 30 seconds of initiating the Prime95 runs.
With the current BIOS setup, Everything looks good in the Blend test (at least to me it does). However, in both the Small FFT runs, im throttled all the way down to 2.9 Ghz and 2.4 Ghz. At these speeds my temps still look decent. If I let the Small FFT's run longer I will eventually get to 80-82 deg C.
So what gives on the clock speed limitation right out of the gate? Temps seem fine so why such a dramatic reduction in clock speed? Is this a voltage drop issue or possibly power/current limitation in a setting somewhere in the BIOS? I appreciate any help yall can offer up.
