Then return it again with PBO of 0 and test again. 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. Firstly, it can be a slightly more powerful 7800X3D if you disabled CCD1. I removed my -22 undervolt and turned off PBO. Performance Tuning/PBO (located either on Main page or AMD Overclocking): "PBO w/TJMAX of 85c Curve Optimizer -20mv". Undervolting with optimistic PBO will get you higher game clocks and performance than all core or BCLK overclocks. 2V and the VID pull on my chip is still at 1. I am 100% sure it is the pbo curve. Please feel free to correct/expand for the benefit of anybody stumbling upon this in the future. 7800x3d would randomly run aida64 sha3 butter smooth or just black screen crash at stock settings no pbo.

I primarily used occt and cinebench previously but I’ll definitely check out core cycler. 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, Anyway, in that experience which is mine I've found that a good manual overclock generally outperforms PBO. I decided to check up on the Intel's counterpart and noticed that while the chip is much worse in terms of performance per watt, it's leagues better than the 7800x3d when it comes to efficiently pulling the required amount of power needed for low requirement tasks. First day has been good with mine paired with an asrock x670e steel legend on latest bios. Skill Flare X5 DDR5-6000 CL30 Memory. It runs at 5. As long as you're not reaching 89c you're fine. 15 Voltage are well within the safety margins of the maximum voltage that can be safely applied to 5nm Ryzen I bought a 7800x3d, and so far I really enjoy it.

If you set your PBO Limits to "Manual" instead of "Auto" or "Motherboard" you can manually type in new limits for PPT/TDC/EDC. Thus, the overshoots from the that 1. and youll be golden. Turn the overlay off, the stuttering was gone. Restored default settings (f7) and reapplied only expo, 5050 boost was back. While the 7800x3d pulls 25w-30w sitting on the desktop, the 13700k will pull 5-15w. PPT - 75000 mV TDC - 120,000 mA EDC - 180,000 mA and it's finished!

The 100 MHz up or down did not yield anything meaningful for games and it was a hassle to use a 3rd party tool to do PBO. For example, my 7800X3D would crash at -20. tj… PBO Enhance Mode + Thermal Limit. T drive health check, GPU undervolt, updating BIOS and more. Do i need to enable this alongside pbo in my advanced settings or is this tweaker setting like a basic version? thanks He speaks about 7800X3D being extremly sensative to Voltage and that any voltage above 1. This allows the cores to run cooler with less power input, which ironically gives them more thermal headroom to boost higher with lower temps. -10 is super safe. You can let PBO automatic but use curve optimizer to get more all core freq out of the CPU. But for any other ryzen chip, boost clocks are limited by thermal headroom. I can get an all core manual overclock of 4. 15ghz on my 2700, by comparison PBO tops out my cores at around 3. Wendell at L1Techs did that and he really stressed how a bog standard nothing special 7800X3D rig can keep up with the tuned, slightly unstable 13900K rig that is using really expensive parts for a far better price and while using a lot lot less power.

In here I have my curve set to a negative 20. 15 with 50mv left to give. 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). if not, try -20, if yes you could try and push to -35 or lower but you will probably lose performance. Here was said that I should use the Curve Optimizer and adjust the limits for PPT, EDC and TDC. Among other things, it was suggested to me to use HWinfo and set the limits so that the values, depending on the situation, should be set between 98% and 99%.

Now if you disable the non-cache CCD, and make the 7950X3D an 8 core simulated 7800X3D, it’s faster. PPT is the max limit (in watts) that the processor is allowed to use. I then noticed the stuttering only happened when my AMD metrics overlay was on. 15 Voltage are well within the safety margins of the maximum voltage that can be safely applied to 5nm Ryzen PPT is one of the things you can change in PBO. Can confirm this guide works really well , still testing though. higher voltage for memory overclock of course. Pbo curve settings in the negative reduce the power draw that each core can receive when they demand power. Memory Profile: XMP/EXPO Profile 1 Memory Performance/Tuning: Set from AGESA Default to Aggressive They have a thicker IHS and are designed to push to their thermal limit.
