You're unsure about comparing the R7 3800X Auto and ASUS OC versions. Let me clarify the differences for you.
You're experiencing some interesting behavior with your AMD Ryzen 7 3800X setup. It seems like the system is maintaining a stable clock and voltage, yet it's switching between fixed and adaptive modes. The benchmark results after ASUS optimization look promising, but you're puzzled by how the performance metrics behave differently in auto vs PBO on versus OC mode. It appears the AI tuning is keeping things at a lower voltage, which might be why it stays consistent, but it also limits potential gains from higher clock speeds. Comparing this to Intel's adaptive voltage scaling, it seems AMD's approach offers stability at the cost of some flexibility. You might want to explore whether your workloads benefit more from a steady lower voltage or if occasional spikes could help performance.
Turn off OC, maintain PBO, set AUTO OC to 200mhz. Then adjust memory usage using Ryzen dram calc. For guidance, 1.35V gradually reduces CPU max voltage; Zen 2 needs 1.325V under heavy cores, 1.47V for single-threaded or light tasks.
So possibly the ASUS AI OC is adjusting things, and using a 1.35 core setup could explain the higher score. An auto OC at 200MHz means the boost frequency is set automatically, while a manual setting of 43.50MHz gives more control. The 4.7 or 4.4 value likely refers to the maximum achievable boost depending on the model. After changing the multiplier from auto to 46, it seems Intel’s auto mode caps at around 4.4 for that chip. AMD probably sticks to its stock clock, which is around 3.9 for the 3800X. The voltage specs can be tricky—some sources say 95°C max, but Ryzen Master shows 1.475V as a typical safe range. ASUS offers both air and water cooling options; using two water coolers probably lets them push higher voltages safely. The lower voltage you noticed might reflect real-world performance rather than just specs. Keep testing temperatures and stability to find the sweet spot.
Thanks for your response and the detailed explanation. It looks like this chip might require more setup than the i7 4790k, especially with the auto settings. I’m a bit puzzled about the voltage requirements—especially since you mentioned liability concerns. From what I understand, when you do significant overclocking, it’s common to stick to the original specs. In my experience, keeping the upper limit at around 1.37 allowed stable performance at 4.6GHz, and with a good cooler, I didn’t face any issues. However, since the manufacturer doesn’t specify exact voltage limits, it’s hard to gauge how well the chip performs at stock settings. I hope my explanation clarified things. Auto voltage seems to push the upper limit higher, but the locked setting keeps it stable, which suggests this chip behaves differently from what I’m used to.
Using the newest 1.0.0.4 Agesa and the latest chipset drivers for Ryzen Balance yields a voltage range of 0.2V to 0.976V during idle. The problem has been resolved. Similar to X99 and X570(Zen2), it took them four months to address the turbo issue, and they still have PBO failures. In most cases, it's wise to wait about six months before upgrading to a newer architecture—I wouldn't be surprised if Zen 3 faces comparable challenges. Additionally, newer chips are achieving higher boost speeds thanks to TSMC's process improvements.
I’ll review my voltage readings in cpu-z upon returning home. Regarding system idle status, I need to disable anti-virus and programs such as AI Suite 3 that manage fans and water pumps. Concerning chipset drivers, I’ve always used AMD versions when using AMD CPUs (Phenom, 8320, 8350) and kept that approach after switching to Intel. However, Intel chipset drivers differ significantly from the basic ones provided by Intel. Now I’m sticking with Asus drivers, which are older than what’s available on AMD sites, but I’m curious if they’re better suited for Asus boards compared to Intel’s drivers or just outdated AMD options.
I forgot to catch the section about disabling other monitoring tools since they’re blocking idle mode. AI Suite seems like it fits that pattern, but I’m stuck using it because I went all-in on a water loop setup. In the motherboard BIOS, the W+ pump header has no control at 100%, which causes the pump to buzz loudly and disrupts the pump’s PWM curve—another issue for Asus BIOS.
