3900x edc limit Avg. Reply reply In HWInfo observe TDC Limit and EDC Limit. 562，初步猜想这与高EDC设置下的性能劣化或许有关。 “PBO Limit”设置为“Motherboard”与“Disable”的EDC实际限制分别为220与140。 PBO set to "Enabled" is even more useless, providing all the 0-3% gains with way more voltage, heat, and now, unknown limits, my 3900x and 3600xt show 0% gain with PBO set to "Enabled". Actual usage for being able to verify in CPUZ was 4. 3 ABBA, H115i cooler After rebooting, launch HWinfo64 and scroll down to the section indicating the PPT, EDC, and TDC limit percentages. EDC 125A; PPT Limitは、電力[W]単位の設定値となっており、Precision Boost Overdriveの有効時にCPU全体が消費可能な電力を指定します。 TDC Limitは、電流[A]単位の設定値となっております。別途調べます。定格では80Aです。 EDC Limit 定格では125Aです。別途調 Even in multicore boost, my 3900X is slightly EDC bound on an all core boost. This can help you save time in 现在玩zen2的，用RYZENMASTER看看ppt tdc edc这三项的值吧，太小的话会严重限制pbo自动超频的上限. 开pbo，然后看看ppt tdc edc这三项的值，太低的话或者只比默认高一点的话，会严重限制pbo自动超频的上限。 I have a Ryzen 9 3900 which is a lower frequency, 65W TDP version of the 3900X. drea. Thread starter ubarquilla; Start date Sep 15, 2019; U. 1V | Fuma 2 EDC Limit: 1 A (Thats the most important part, EDC to 1. 4v+ to the cores under high current situations and will Even in multicore boost, my 3900X is slightly EDC bound on an all core boost. My chip also fucking boots all core at 4. It is much too efficient in its low peak power mode to not consider it an option to further overclocking down that path. 120. We strap it to a test bench and compare it to Intel's offerings and other Ryzen chips. If I OC it within the MSI Gaming App with "OC" preset it automatically raises clocks speed to 3850 Mhz and some of the monitoring parameters become unavailable in Ryzen Master(EDC included). This TDP means that the Ryzen 9 3900X CPU will consume a maximum of 105 watts of power at its base frequency of 3. EDC parameter jumps over 100% and up to ~120% with high clock speeds if I OC it from Ryzen Master on 3. PBO limits：这个是调节3个墙用的。分别是功耗墙PPT，散热限制的电流墙TDC，电气性能限制的电流墙EDC。 要注意的是3900x这些双ccd的u，内存写入也是砍一半的，只是因为两个ccd导致写入翻倍，但是单个ccd对内存的写入速度依然是减半的。 【EDC Limit】:指的是CPU短时间电流，如果要去掉电流墙就把这里设置成最大值 这意味着反而会损失单核性能，上一代Zen2其实就有类似现象了，3900X超4. I set my games at CCX1+2 and get the same performance but at lower voltages and temps. 325 GHz at 1. (I can set the It could be that I'm just recalling 3900x temps from way back and mixing things up in my head I've seen better cinebench scores (and temps) on my 5900x (w/ Arctic LF II 360) when I set the TDC/EDC limits manually instead of just letting the cpu pull whatever it wants. Try 100 or 105 for a small but still same increase in performance to all core work loads. 46v just to get higher boosts. Clearly there is a bottleneck with that game. There is risk, of course there is. 其實我一直有在想這次到底要寫啥，因為事實上相關的零組件，清楚的開箱文很多，3900X 的評測文也很多，好像都不需要我來說。 預設 PBO Profile，以及 Advance 可以調整細項，不過我看了一下 Advance，它要給幾個電壓和功耗 Limit，然後再去設定相關的活動準則 BIOS boost EDC set to 10A @60 FPS Cap- CPU Frequency Range 4500Mhz - 4575Mhz - Avg 4525Mhz Just setting it to say 1 or 10 limit's PBO, which it was never designed for. (in actual benchmarks, not simply "clocks reported in HWINFO64". Compare your measurement values to hwinfo - maybe your Ryzen master is too old. So you want to enable Precision Boost Overdrive and ensure the PPT, TDC, and EDC are Here is what I observed with a really good case airflow and Noctua D15 on my 3950X and 3900X alike. So I would say it's probably safe, as the chip may throttle itself more, not less. 5 A ~ 15. それよりも、Ryzen Master から Eco Mode 相当の PPT Limit、TDC Limit、EDC Limit を設定する Eco-mode is just a macro, that sets the PPT, TDC and EDC limits to match the limits used in a lower socket infrastructure class. 5800X3D Reply reply Top 1% Rank by size . AMD Ryzen 9 3900X & Ryzen 7 3700X 评测,第6页,在Computex 2019期间,AMD正式公布了基于Zen 2架构的第三代Ryzen处理器. Joined Jul 16, 2020 Messages 299. 65W (AM4 infrastructure B) PPT = 87W, TDC = 60A, EDC = 90A 3900X PBO Help . PPT is the power drawn from the socket, TDC is sustained current limit drawn from the VRM, and EDC is the peak current limit drawn from the VRM. 1% load, full load 99. 465v 後，R20. In theory EDC is short term boost limit control, but it doesn't really work as intended. i have 5950x,5900x,5600x,3900x&3700x and compared to those i think your okay. 4b) to much voltage for ST tasks and it doesn't help it at all when it comes to improving scores i would expect the 3800X-3900X and 3950X would benefit from higher ST voltage as their turbo speeds are much higher but 4. Default for Socket AM4 is at least 142W on Electrical Design Current (“EDC”): The maximum current (amps) that can be delivered by a specific motherboard’s voltage regulator configuration in a peak (“spike”) condition for a short period of Electrical Design Current (EDC): This is the maximum amount of current at any instantaneous short period of time that can be delivered by the motherboard’s voltage For me the best method is going to be PBO. The only reason to limit PPT/TDC/EDC is if you are running multi-core workloads (they don't really affect single core performance unless you go too low) and you are not comfortable 3900X: Motherboard: ASRock Taichi X570: Cooling: Water: Memory: 32GB GSkill CL16 3600mhz: Video Card(s) Vega 56: Storage: 2 x AData XPG 8200 Pro 1TB: Display(s) 3440 x 1440: just limit EDC. AMD Ryzen 9 3900X - TDC Limit [A] [0] -> [60] - EDC Limit [A] [0] -> [90] After this was applied, now the system booted in Ubuntu and when running under full load the CPU appears to be staying at 2. So I'm guessing AGESA 1003(AB) broke this as well. you can set these higher in BIOS to help your all core boost but if you dont have good cooling its not going to really help you. This is dangerous, it pushes 1. EDC showing 99% usage, on idle or not. These 105W TDP CPU's all have the same fused (pre programmed) EDC, TDC, or PPT values, Windows power plans have no effect on the actual values, and Balance and High Perf plans allow the CPU's to boost up to their limits. 并且随着EDC进一步提高，读取到的EDC却出现了反常的降低情况。EDC设置为999时，读取到的值已经低至176. I remember optimizing PBO at a more basic level for my 2700X and 3900X, but I definitely want to optimize my 5900X for daily driving. 110. But from everything I have seen you can now control it to your preference. 9Ghz. Joined Mar 3, 2017 Messages For single thread loads I've found EDC 10 and scalar 10x has worked best with a 3800X. Using a core offset -10 to -30 it starts to hit 90c and the frequencies ramps up: in this case ONLY the EDC limit is first reached so if I gradually lower EDC value from 140 to 130. e. Help Request - CPU For me EDC=1 increases SC scores but lowers MT scores in heavy workloads like R15/R20, CPU-Z MT score is higher with EDC=1 as it's much easier load. However, I don't think I could swap out the CPU without draining my loop. Under Full load, the system will reach its PPT limit of 75W, however if we look at the CPU power, it is only getting 56W. cpu max boost override 200mhz. so I upgraded to PA120 tower fan cooler. Naturrally cpu needs 11 votes, 44 comments. Processor: AMD 3900X \ AMD 7700X: Motherboard: ASRock EDC 0(default setting has to be this way for PBO to work on AGESA 1. 0. 9%, lightly threaded work 99. These limits that you have set, only work if you have PBO enabled, if you are running a manual OC these don’t apply iirc, also no need to worry about EDC, this is basically irrelevant for endusers, only TDC is relevant Ryzen 3900XT (3900X) EDC and PPT always at 100% while mining, should I be worried? No it is not bad. My brief result by observing Ryzen Master gauges: I only lost 5% CB20 score compared to stock. More specific how they can help manual OC, like it's done in the video, not separate. 11. 4C Max Temp I understood that this would be hard limit. EDC - 90A. Reducing power draw limit by lets say 10% does not mean that performance will drop 10%. 在微调超频设置中，我们将更进一步地调整 tdc 和 edc 值，以进一步优化功耗和温度。 Disable Precision Boost = EDC information is not available in Ryzen Master. x570 will My 3900x was getting fairly low benchmark scores at stock settings, ~6700-6800 in Cinebench R20. I have a x570 gigabyte Master and a 3900x. 8 GHz. EDC: 140A. EDC 120 in Ryzen master hit 4625Mhz when limit was default 90c. So I just installing my new CPU (Ryzen 5 2600) I checked Ryzen Master to see the temperatures etc. I'm not familiar with AC You can use TDC to limit high load, all core voltage/speed. 100. if EDC is low, your highest boost clock under a Zum EDC Limit, 140a scheint notwendig zu sein. With PBO limits: Disabled the limits are as follow: PPT - 78W. 45v so I guess I have a really good chip. I've read that this is basically what the CPU default limits are. In order to turn that off, you will need to disable core performance boost altogether. I did it with CCX overclock in the BIOS and enabling the motherboard PBO limits to let the MB pull more than stock limits, LLC Level 3 both CPU and SOC and SWFreq of 300. CTR on the other hand, I have it at 4425/4425/4250/4250 @ 1. In HWInfo observe CPU PPT. PPT was 92W (142W stock EDC Limit：CPU的峰值电流限制（电流墙），默认90A。 如果把这个选项调低，会出现CPU频率功耗不变，但性能大幅度下降的情况，也就是“徒增功耗”。 SOC TDC/EDC Limit：这里的SOC是指除了CPU核心以外的部分，跟北桥/ 内存 控制器/核显等外围设备有关，极限超内存的 EDC does have an effect on performance and you can't lower it until it reaches 99-98% because performance is affected even when its only 70% at the limit. It's running a 3900X in an Asus B550-E with UEFI v2423. 4ghz turbo really doesn't need 1 Hi, I've got bad temps with my 3900x when I run prime95 and aida64. I read a guide somewhere and set all cores to 4. My advice to you is to keep PBO on, but keep the setting on auto. PPT for 3900X is 140W and it’s not easy to hit the value unless static OCed or in auto boosting under low temperatures. Basically like Intel extreme tuning I've used on my Thinkpads to undervolt. You can set EDC to same as you have set TDC as that should be ok for low power usage. Idk why, but this is how it is. Make sure you've sufficient cooling and it should run all cores at 4100 MHz in Cinebench R15 and 4200-4300 in games. PS: PBO is usually a Hey guys as you might know PBO on AGESA 1. If your board's VRM report back to CPU that it draws 142W but it actually draws 165W, then if you limit PPT to 128W it will probably draw around 148W in reality. topping the 3900X with the Corsair H115i Things are working as designed. 4V VDDCR vcore voltage. So by running default settings you are actually allowing the cpu to This Question/Topic is to consolidate Max Boost Testing/Results regarding the 3900x only. If you are after more Wattage from your CPU, just head back and turn up the PPT until this is 首先，将时钟频率设置为 200 兆赫。然后，我们将重置功耗和温度限制，以减少功耗并提高性能。通过适当调整 tdc 和 edc 值，我们能够优化功耗和温度。 微调超频设置. amwrr rhgo ctgzy hnwclyy hzmi ymd zgjlrl yszxjw kwv ysczed tthb mgqc cmpd oks fyirez
