AMD Ryzen 7 3700X Overclock Benchmarks

I don't reccomend overclocking manually, instead I recommend just enabling PBO, however if you really do want to overclock manually here is what you should do.

Ryzen 3rd gen at stock can automatically boost 1.5v when it is safe to do so , but when manually overclocking you should not run nearly that much, even voltages as low as 1.2v may be unsafe.

The safe voltage for manual OCs varies from CPU to CPU, you can find it out with the following method:

  • Enable PBO, all other CPU OC settings default.

  • Launch Prime95 Small-FFTs in Windows.

  • Launch HWInfo64 in Sensors Only mode.

  • Wait a little while. (At least 5 minutes)

  • Check the SVI2 TFN Core Voltage Sensor in HWInfo64. The minimum reported value is your CPUs safe voltage.

  • Stop Prime95.

  • On some motherboards that don't behave normally you also have to set the PPT, EDC, and TDC to 1000 in PBO settings after step 1.

    Once you have found your CPUs safe voltage I recommend setting that in the BIOS and just trying various clock speeds until you find your maximum stable CPU clock speed.

    If you want 100% stable I recommend using Prime95 Small-FFTs to stability test, if you want stable enough for most people then I recommend Asus Rog Realbench. I recommend testing for 30 minutes to 2 hours while trying to find the maximum stable clock speed, then once you have found it I recommend 4-8 hours of stress testing to get the best performance.

    You should also be aware that in some cases a manual overclock can result in worse performance than PBO.

    ZEN2 CPUs when are on very light load like browsing, with low current(A), they boost to highest with max votage. Even 1.5+V for very short time and rapidly like bursts. If there is a sustain load, even single threaded the drop to 1.4+V. When load increase more, they drop frequency and voltage further up to 100% load where they drop to minimum "sustained" frequency and voltage depending on the quality of CPU, the temp and current(A). Even then frequency and voltage are not fully sustained but fluctuate (a few hundred times/sec) and no software can catch this.
    If CPU is on auto, dont be afraid. It knows what its doing. Even if you have PBO enabled.

    Even if your board is sending false feedback to CPU about its power consumption (lower than true) to push it more, it can't hurt it, if the CPU settings are Auto, like you have.

    So, in the past, I have never cared about overclocking or seriously tweaking in the bios. My first build was with an Athlon xp and a 9800pro, that will tell you how long I have been a builder(for myself and the occasional family member.) Back then tweaking was more serious and, quite honestly, it was tough to risk parts you could not replace. Over the past 15 years or so I have simply bought the best intel chip, the best nvidia card, enabled xmp and called it a day. So here I am today all in on 2 Ryzen builds because, well we get older and, hopefully, have more funds for this hobby, AMD finally gets it shit together and makes a compelling product that is interesting enough for me to finally switch back. Interesting, as I made these recent purchases I kept saying that to myself. AMD is more interesting right now, they are trying some things that are not brute force and competing. Now I am sitting here with my 3700x and my 5700xt and I have done the same thing I always do, xmp enabled, all else to auto, job done.

    It doesn't feel quite right. This is a fully custom water loop system, and my temps are not where they should be. Don't misunderstand, the temps are ok, idle mid 30's and 79 under AIDA64 stress test. However I do know water cooling, I have done it alot. That is good but not quite what it should be. I have tested and tried everything on the hardware side, trust me on this, I have gone overkill on cooling hardware. Please do not misunderstand, I am not afraid for my cpu or system, it runs fine, but I have read so much about voltage, PBO, setting everything up right with ryzen master, power plans, etc etc. I do believe that as a Ryzen owner there are some tweaks that I need to make to get the temps that I should have and to get the most out of it.

    So that is what I am asking, is there a definitive guide to how to optimize ryzen processors? Can one of you guide me through the process? Yes there are lots of opinions on the internet, but I trust these forums rather than some guy with a blog or, god forbid reddit.

    I am using an Asrock x570 Taichi, 3700x, gskill trident z neo 3600. Bios is up to date as is chipset. I humbly ask for your knowledge.

    All I can tell you is PBO essentially makes manual overclocking almost pointless. However, if you can figure out per CCX overclocking, then it may be worth it. I have a 3600 and 2 x 3700X's and manually overclocking them really makes no noticeable difference.

    Safe voltage 3700x

    3700X voltages

    Voltage alone doesn't say really anything. All ZEN2 CPUs when idling or light/middle loaded (browsing/watching videos or even gaming) are running around 1.4~1.5V but not constantly. When the load is starting to increase they gradually drop voltage until the level to 100% load voltage which is different for any SKU (1.25~1.35V). High voltage with low load, hence low current(A) and low PPT(W) does not produce high temperatures.
    What power plan are you using? Win version latest? BIOS version latest? Chipset drivers latest (from AMD website)?

    Look my 3600 on light load (~2%) hitting (on very short bursts) almost max boost (4.2GHz) and 1.45V (SVI2 TFN sensor).

    Buildzoid's thoughts on safe voltages for static Ryzen 3000 overclocking.

    Also critical to today’s story is the understanding of what a “safe voltage” is. When manufacturers, media, and overclockers provide guidance of “safe voltages” for 24/7 use, they may be referencing different numbers. For instance, suppose GN recommends a safe Vcore of 1.4V for 24/7 on Processor X. In this instance, we have not clarified what “1.4V” means – it could mean 1.4V going into the CPU, period, as measured in the most accurate way possible (e.g. DMM to the socket). It could also mean 1.4V input into BIOS or UEFI. We might mean 1.4V as read through HWINFO or AIDA. Without that specificity, the best to hope for is that all of these numbers are reasonably close. That’s partly on motherboard makers to achieve through LLC tables, but there will always be some disparity. What matters most is that the disparity between actual Vcore (in this example) and input Vcore isn’t great enough to seriously damage anything.

    When we talk damage with parts, we’re talking long-term degradation. Some easy examples would be the System Agent voltage for Intel CPUs (VCCSA); increasing VCCSA to, for example, 1.4V is inadvisable for modern platforms, and will inevitably damage the IMC. For AMD, we might instead talk about SOC voltage – that’s our topic today. Increasing SOC voltage beyond recommended settings, discussed below, would have the effect of damaging the IMC and the APU GFX component’s overclocking ability.

    Over time, a degrading IMC may require more voltage to keep the same memory/GFX frequencies, or it might just lose that frequency altogether, forcing the user to downclock. Outright failure doesn’t happen at voltages close to reason, but will instead manifest over a period of months.

    Of course, the other side of this is the ability to kill a motherboard, which we already demonstrated here.

    General Notes 

    1. From speaking with numerous contacts at motherboard makers, AMD, and XOCers, general advisement on unsafe SOC voltages is that it begins beyond 1.3V. Conventional wisdom (starting with Ryzen) is that 1.2V is a safe SOC voltage, but we’ve been told by some vendors that Raven Ridge CPUs can reasonably take up to 1.3V, but the suggested input number tends to be 1.2V; this is because, again, the user-configured number and the actual voltage aren’t necessarily equal. Going significantly beyond 1.3V for sustained periods, e.g. 1.34, will likely result in degradation of the IMC over time.
    2. Although AMD may suggest that 1.3V is “safe,” keep in mind that typing in “1.3” and actual 1.3V to SOC are very different things, especially when you consider that software often underreports voltage.
    3. Vdroop can require higher LLC levels to stabilize the input voltage closer to the configured number.
    4. LLC tables on some boards can cause undesired spikes in voltage that can be deadly to the SOC or IMC. We have a separate video on how LLC works.
    5. VDDCR SOC Power represents uncore and GPU domain power draw or voltage configuration.
    6. SETTING 1.3 DOES NOT MEAN IT WILL NECESSARILY BE 1.3V FLAT. Voltages are not static. For example, in some of our tests, setting 1.3V with auto LLC could result in sustained SOC voltages of 1.39V, which will degrade your IMC in a matter of months. On Raven Ridge, this will also affect graphics performance.
    7. APU GFX and SOC GFX all go through the SOC. They all go through the SOC VRM. If you adjust one, you are essentially adjusting both.

    Test Methodology

    For testing, we first determined where to take socket measurements by finding a corresponding capacitor to the SOC VRM. We then took live measurements of the SOC voltage at the back of the socket, which we compared versus HWINFO and Ryzen Master or BIOS settings. Some of this is shown in the video.

    Here’s a table of our ASUS SOC checks. The color coding (in the video) is based on frequencies; when we changed frequency, we changed row color. At 1.1V SOC and 1.1V APU GFX input, we were measuring 1.12-1.13V with a multimeter, or 1.056 to 1.081 with HWINFO. This was with a low 1300MHz frequency. Going to 1550MHz had 1.1V SOC and 1.2V GFX reading out as 1.223V via DMM, or 1.15-1.181V via HWINFO. That’s with High LLC, which was required for stability.

    Here’s the dangerous one: At 1600MHz and with Extreme LLC, we configured 1.2V SOC and 1.2V GFX, and read out 1.35V SOC via DMM. If you were relying on HWINFO, you’d think you were only at 1.29 to 1.3V, which are sort of acceptable, though pushing it. Not really acceptable on this motherboard, mind you, but conventional wisdom would suggest that 1.25V is OK for most APUs, according to some of our motherboard contacts. This board isn’t really meant to push this high, but that’s beside the point. The point is that these voltages – 1.2 on each – degrade the IMC over time. That was with Extreme LLC, though. Let’s dial back to auto, since that’s what most people use. Even with Auto LLC, a 1650MHz clock was held with a 1.2V SOC and 1.3V GFX voltage. In reality, these numbers equaled 1.37V and up. In other words, hope you don’t need a memory controller for very long.

    The MSI B350 Tomahawk is next. This one sometimes had Vdroop, but not always. We also noticed APU GFX Voltage didn’t seem to do anything on this board. It was all driven by normal SOC voltage. Going for 1600MHz with a 1.2V SOC and 1.2V GFX allowed the frequency to hold, using auto LLC. The DMM output was 1.245V, while HWINFO reported 1.18-1.2V. Increasing GFX voltage to 1.3V did nothing, and did not change the voltage readings at all. Going to 1650MHz at 1.3V SOC had us reading 1.35 via the DMM, but HWINFO had us reading 1.27 to 1.3V.

    Finally, the Gigabyte Gaming K5 seems to push voltage more heavily than other boards. This isn’t inherently a fault with Gigabyte’s motherboard, it’s just that users need to be aware that the behavior on this board is different from the MSI and ASUS boards, which means that following a guide for a different motherboard could easily have you inputting unsafe voltages.

    At 1500MHz and with a 1.1V SOC, 1.2V GFX via BIOS, we measured a 1.3V output via DMM. HWINFO read 1.1V. Going to 1.1V SOC and 1.3V GFX gave us 1.39 to 1.4V SOC, which is dangerous to the health of the IMC.

    This is where we realized that Gigabyte was being more aggressive than MSI – again, that’s not a fault of either, just a behavior. We dropped to 1.15V GFX input voltage, which resulted in a 1.25V DMM reading. As you can see in this table, 1650MHz was held with an input number of 1.1V SOC and 1.18125V GFX, resulting in a 1.28V SOC voltage as measured at the socket, but 1.1V via HWINFO. The takeaway here is that the Gigabyte board only required us to input 1.18V for GFX to get 1.3V out, whereas the MSI board would require a 1.3V input to get roughly the same out. The ASUS board would require 1.2-1.25V to get 1.3V out. These are behaviors that you need to be aware of on the motherboards, and they are somewhat unique to each board.

    Conclusion

    The main take-away here is that establishing a “safety” voltage is important, but ensuring that the voltage provision actually equates the safety input is more important. If we’ve decided that “1.3” is safe for SOC, it’s not good enough to just stop incrementing voltage once BIOS reads “1.3.” There needs to be another check.

    In speaking with various contacts, we’ve heard a few conflicting (but generally converging) guidelines for safe voltages:

    • Our understanding is that an AMD-made overclocking video for Ryzen (not Raven Ridge) suggested a 1.2V SOC voltage. This was at Ryzen’s launch, so is potentially outdated.
    • ASUS once recommended 1.25V SOC maximally.
    • Gigabyte has suggested that up to 1.3V should be OK, but spiking or maintaining spikes beyond 1.3V could be damaging to the SOC.
    • Buildzoid has suggested a safety of 1.2V, which also aligns with what most early Ryzen overclocking guidelines suggested; note that this is specifically for Ryzen, not necessarily for Raven Ridge.
    • Other contacts have suggested between 1.2V and 1.3V.

    If you ask us, we think decent overclocks are achievable with 1.2-1.25V SOC going into the socket, and that more than that isn’t really necessary, anyway.
