Let us know if your final score improved for science LLC is not, by any means, a type of undervolting. Very confused on why I'm not getting more out of this, and disappointed I cant figure it out. Here was said that I should use the Curve Optimizer and adjust the limits for PPT, EDC and TDC. If I go further to -20, the system no longer starts. pretty much every game I play doubled my fps. It compensates the voltage drops when starting a heavy task, so the cpu is more stable. It seems for the 7800X3D you're already towards the top of the curve. I have two different rigs one is a 3800x b450 and one is a 5700x b550f Both are relatively expensive builds one more so than the other.

No: because PBO still adheres to silicon fitness, and unless you're also running a voltage scalar, higher PBO limits alone should not meaningfully reduce the CPU lifespan. First of all, my specs are 7800X3D, B650 Aorus Elite AX, 32gb Corsair Vengeance 5600mhz CL36 RAM. I haven't done any tweaking to my 7800x3d yet, so I was looking at curve optimizer and PBO. Intel Core i9-13900K: 1080p, PBO Boost override: -100mhz. Set thermal throttle limit to 85c I score ~18,700. psa pbo scalar . But for any other ryzen chip, boost clocks are limited by thermal headroom. By default this is set to 162 for the 7800X3D. You can try adjusting the PBO voltage PBO - Each core set to -25; Thermal Llimit - 85; Medium Load Boostit - DIsabled under AI Tweaks You can set PBO enabled and force it to +200 all you want but if you hit high temperatures you won't see good returns at all. I could run various loads and then watch the clocks as I worked up and down on values to see the difference even trivial things like scalar made.

I checked drivers (updated mobo, an nzxt b650e, too) and this is a fresh install on wiped drives from my 9600k build. With that said your Temps seem fine to me. In the advance section of PBO, set PBO limits to motherboard or manual and set values that you won’t realistically hit. overclock memory a bit and tighter timings. At the end, the higher the LLC value, the less UV is applied, helping the stability. Just to see what it would do, I spent the time to setup a mild PBO curve optimiser in BIOS (-15, scalar 10X, motherboard power limits) and got a better result (18200 CBR23, Polygon Labs develops Ethereum scaling solutions for Polygon protocols, collaborating with ecosystem developers to offer scalable, affordable, and eco-friendly Web3 infrastructure. , i was getting multi 18200 and single core 1800.

PBO Scalar: Auto. And will sustain full 4. : All Core -30 Cpu AIO at 100% With the above settings i see my pc cpu edging at 4. Using PBO will make your CPU run hotter by default since it’s trying to maximize performance within the thermal headroom, the Curve Optimizer would make them run cooler by undervolting. It does do something. So enhanced mode 2 is definitely a branch of PBO. Yes better cooling will Full disclosure: I've got an R7 2700 with a 360mm cooler, so my experience may not jive with your experience. So, I noticed people saying that it was safe to enable PBO on a 7800x3d so I did so with a -30 (seemed like a common number people were using). This allows the cores to run cooler with less power input, which ironically gives them more thermal headroom to boost I suspect the same goes for Scalar, it maintains a higher voltage level while boosting with PBO. The overdrive Scalar doesn't do shit on my mobo haha so your milage may vary but yeah and 300/240/240 aren't absolute numbers your just telling the chip know " hey you can go this high" AMD Ryzen 7 7800X3D vs. But no one knows whether or not you have silicon which will tolerate slightly higher current for 8 months or 8 years, and no one can say for sure whether or not your particular PBO values will result in I just put in a 7800x3d and my idle temps seem high at around 35c.
