This means that AMD could have likely assigned an extra On the PBO advanced menu click on curve optimizer > all cores > negative. I then noticed the stuttering only happened when my AMD metrics overlay was on. I had the same issue right after upgrading to AM5 with a 7800X3D. Then I turn the power source off and unplug the stick. I started at -15, benched it with cinebench and after getting good results I increased the offset to -20 pbo. 05ghz. 65W eco mode is a PPT of 88W. I'd turn off pbo enhancement and just do a core offset. This modifies the clock speed and voltage the processor runs at a thousand times a second to deliver higher performance than at the base. these settings give great result for the 7800x3d. Are you saying pbo is better off?? I recently enabled it and even did a negative curve of 30 to all cores. 15V is going to push the CPU to the maximum (TJ max) on medium to heavy workloads. 7800x3d - PBO, CO-20, EXPO 6000mhz cl30, getting weird readings of 1000c+ on DDR5 Help Request - RAM So new to the am5 platform, been noticing this happening in hwinfo64, https://ibb. With a 7800x3d the tjmax is 89c. 7800x3d is already a ridiculously efficient chip but, apparently, I can blindly go to PBO and set all core to negative 35 and straight up runs cinebench for 3 hours now no crash. The chip, which leverages AMD's second-gen 3D V-Cache to boost L3 capacity to 128MB, beats Intel's Core i9-13900K in gaming by 7%. It might just be called advanced cpu options.

Hey, you might know what I'm missing: I switched from an Asus b650e-e to an msi x670e carbon. This allows the cores to run cooler with less power input, which ironically gives them more thermal headroom to boost higher with lower temps. In here I have my curve set to a negative 20. So its fine. But so far my settings are: core 0 -30 core 1* -35 core 2 -30 core 3** -30 core 4 -30 core 5-30 My 7800x3d runs at -40 and Extreme LLC (there is a Super Extreme option by the way which completely flattens the line that I am scared to use).

Benched again, left it at that and never had a problem again. and do that for each core til u got all there maxs. Real life differences between these CPUs are also not 600 MHz (PBO frequencies are a bit of a weird concept and based on the motherboard you are using can be a bit higher than official AMD numbers). It compensates the voltage drops when starting a heavy task, so the cpu is more stable. My 7950x3d still boosts to max frequency on both cores quite often. 2 ghz. While the 7800x3d pulls 25w-30w sitting on the desktop, the 13700k will pull 5-15w. -15 should work mostly as well.
