Question PBO plus Curve Optimizer?
Question PBO plus Curve Optimizer?
Someone can clarify this for you clearly. It seems like a free performance, but you're hesitant to try it because of uncertainty. You turned on PBO in your BIOS, but aren't sure if continuing is right or what to do next. You mentioned upgrading from a 3070 to a 5070 Ti with a 5800x and 1440p monitor. In games like Battlefield V, you're seeing high GPU usage (around 60%) while CPU usage stays low (80-90%). You were told PBO would help, but there are more steps involved. It's worth checking if this could address the bottleneck before deciding to skip it. If you're unsure, it might be safer not to proceed without proper guidance.
Are you using XMP speeds for your RAM? Open Task Manager, go to Memory section, and verify the "Speed" setting is at 3600. If it's not, you'll need to turn on XMP in BIOS. PBO can boost CPU performance when you're not limited by heat or power, though it won't give a major improvement as expected. Based on what I see, your CPU and GPU seem well-matched without any bottlenecks, so the issue might lie elsewhere—possibly in software or BIOS settings. Don't hesitate to check the BIOS for XMP options specific to your motherboard model. Just search for the right instructions and follow them carefully; changing settings should be safe as long as you stick to what was recommended.
I have XMP enabled and the CPU is set to 3600 in Task Manager. How can I figure out if something is wrong? I think the CPU is limiting the GPU performance. I've tried Cyberpunk, but my CPU usage stays high even though my GPU usage doesn't reach maximum. What should I do?
Ensure you have a reliable power supply before proceeding. Identify the model and wattage of your 850W unit, as well as the type of CPU cooler it uses. Boosting CPU workload raises its power usage and heat output, which may lead to instability or damage. The available MBOO VRM ratings are mid-range, but Heastsink doesn’t cover them fully—this wouldn’t be my preferred board to use. If any requirements aren’t met, skip the attempt. Excessive power draw could overload your supply or cause CPU overheating, requiring a high-quality cooler to maintain safe operating temperatures. Even top-tier coolers might struggle if the chip die size limits effective heat dissipation due to physical constraints. Before attempting an overclock, familiarize yourself with stress testing methods and monitor temperatures using various applications. There are some overclocking guides available; it seems you’re still struggling to achieve the desired image quality at 1440p. Don’t worry about the FPS improvements—overclocking isn’t worth the risk compared to the minimal gains. Besides learning how to back up your data, a clean installation with fresh drivers and spare parts would be ideal. If you truly want to proceed, press the button and see if performance improves, but be aware it’s not recommended for beginners.
I recommend you start by re-installing your nvidia drivers or updating to the latest ones if you haven't. Also first you should check what kind of performance others with the same system specs are getting out of the combo. For example cyberpunk with Ultra preset should be giving you around 70-80 FPS as seen in this video:

If the performance is similar then I would say that the usage percentage does not matter as much. If it's much lower then I would make sure everything is updated. If I cant find a solution I'd just go ahead and reset windows as there's usually a high chance of a software bug somewhere that may take ages to find and fix.
I purchased a new PSU with the 5070 Ti last week, using the Corsair 850rmx. I have a Noctua NH-D9L cooler and my CPU has never exceeded 78% during gaming.
It's not really about the FPS improvements—it's more about easing the CPU bottleneck. Getting 60% GPU usage at its maximum in Battlefield V isn't normal, isn't it? Along with 80-90% CPU usage while keeping 130 FPS, that doesn't seem right for a 5070 Ti.
It's typical for a 5800x. Highly optimized rigs with overclocked memory could perform better, but achieving that requires careful planning from the design phase to justify the investment. Getting the desired RAM is also challenging these days, let alone getting it to function at DDR4 3800, as it remains extremely rare and mostly found in older AM4 X3D CPUs. G.Skill's DDR4 Samsung B Die offers quality but is now considered obsolete. The CPU struggles to push the GPU to its full potential, which is the main limitation.
I thought this pbo and curve adjustment could really assist, but it's something I've never tried before. Honestly, I'm nervous about tackling it. I just hope Battlefield 6 will run smoothly so I can get the right frame rate on my monitor. All the games I have installed so far are having trouble due to CPU limitations, and I'm especially worried about BF6.
It won't reach 165 fps even with the 5800x3d card consistently, especially on the ultra preset.
Check hwinfo to confirm your memory is operating at the expected speed and that the UCLK (memory bus) matches the FCLK (infinity fabric) in a 1:1 ratio. This setup helps achieve lower latency, which Ryzen prefers.
You might also adjust a memory setting in the BIOS—switching off power down mode can slightly improve latency without needing deep memory timing adjustments.
However, this change is likely to be limited by the quality of your RAM kit; using it could cause instability and crashes. You’d need to revert it back to default settings (power down mode) if you decide to keep it.
This adjustment should be found in the advanced BIOS configuration menu.
Without a detailed guide for every board, it’s hard to pinpoint exactly what you’re dealing with.
If you share your memory’s specifications—like part number and latency details—it would help determine whether it’s a low-end, mid, or high-tier kit.
Reading the specs in the burner can give you an idea of the RAM quality, but be cautious; software tweaks can damage the RAM if not done carefully.
The key is understanding your RAM type and ensuring it matches the system requirements.
If you haven’t enabled XMP in the BIOS or manually adjusted timings, that could also be a factor.
You can verify your memory speed by right-clicking the taskbar, opening Task Manager, then Performance tab—look for 3600MHz.
If it matches, you’re hitting the hardware limit.
Beyond that, consider lower-quality presets or NVIDIA Cpanel tweaks in the game/gpu settings.
There’s also a third-party frame generation app available in Steam, though it’s not free and lacks a trial version.
People often experiment with these options, but they’re not recommended for beginners.
in task manager it displays 3600, but i took a picture of HWINFO and i'm not sure what i'm seeing there.
i think this is the information you have:
G.Skill Trident Z Neo RGB DDR4 3600MHz 2x8GB (F4-3600C16D-16GTZNC)
i prefer to avoid frame gem and enjoy competitive play.
