The 5600x in my new A520 board goes to 4. When combined with very high all core frequency and curve offsets, my guess is that it generates a lot more heat than the algorithm expects at unmodified frequencies. 325v for 4. In the video AMD released about PBO2, they set the scaler to 10x. You will actually see the instability when the pc is at idle. Latest bios, cooler is a NH-D15. Never on full load. With pbo2 curve optimiser i dropped almost 10c and can sustain 4450 MHz all core.

I can already guess that the first comment is gonna be "Doubt thats stable" More than a year user of 5900x, recently started using it undervolted to 1. Not to mention in heavily threaded games where a variety of threads are spread out over both CCDs of a 5900x, and each CCD has 32MB of L3 cache, the advantage of the 5800X3D in L3 cache is only 32MB, and the disadvantage in stock clockspeeds and the inability of the user to tweak PBO2 settings and the Curve Optimizer very much cloud the issue. 20ghz to 4. Trident Z 16x2 3200 14, Meshify 2, Seasonic Prime For example on my friends 5900x (-23 best two cores, -28 rest) I can set +200mhz boost override and it will reach 5.

The best I could do with core 0 is to get -15 stable on the curve by increasing the vddg CCD voltage. The AMD website proclaims that the 5900x max temp is 90 Celsius. The temps can get up to 105°C when overclocking, or using pbo2. I finally have a rock stable OC on my 5900x! Really great temps and decent scores but had an outstanding question: is it better to use the offset CPU voltage or better to leave that auto and focus only on curve Optimizer offsets? I recently started looking into PBO2 and Curve Optimizer for the 5900X I got recently. Should I try to accomplish this level of lower range temps by changing further settings elsewhere in the Bios instead of using the energy settings in Windows? These are results for 5900X with Curve Optimizer set for negative offset per core (-22 normal cores, -16 2 second best cores, -12 best cores) + 150mhz boost.
