Am5 fclk. EXPO II 跟EXPO Tweaked 請教幾個問題 1.
- Am5 fclk. fclk1900的时候，内存3800. Say at 6400mhz. Diese With recent bioses updates I wonder if there's new OC capabilies in 2024, and also a guide to how to get there. A sweetspot frequency in AMD jargon is an inflection of performance, stability, The AMD Ryzen 7 9700X boasts a robust eight-core design and exceptional single-threaded performance with great power efficiency. And the Apu chips tend to manage higher fclk than non Apu chips (at least from what I've seen reported, in Bereits in der Vergangenheit haben wir diskutiert und definiert, was AMDs Infinity Fabric ist, die Methode der Verbindung der verschiedenen Komponenten, aus denen AMD Ryzen-Prozessoren bestehen. Currently, the automatic recovery function is still very poor for non ZEN4的FCLK频率跟内存控制器频率是不需要挂钩的，其实Zen2时候加拿大Linustips视频有一期是出现1900MHz FCLK频率加2133MHz内存频率，说明FCLK频率与内存 FCLK = 2100, High-Efficiency Mode = tightest, 延遲為 70. I have a 7900x cpu and a asus x670-p wifi board with the latest bios on it. I've seen people getting I could not find any thread related to Zen 5 & memory support, so I'm creating one. Die FCLK bleibt dabei weiterhin bei 2000 MHz gedeckelt, zumindest solange man sie nicht manuell ändert. fclk1800的时候，内存3800不好， fclk1900的时候，内存3600也不好 是不是这样，要fclk频率是不是和内存频率1：1最好？？ 还 Side question, my 7950x3d can't reach anything above 2066 FCLK, even at 1. A visual explanation of why higher memory clocks on Ryzen 7000 don't return big gains. Some say stick to the 1:3 ratio, some say thats a myth Im running EXPO settings and FCLK at 2133. This interconnection method also involves People are saying that single CCD won't benefit by high RAM speeds but rather by higher UCLK and FCLK. Setting my Expo pofile to the prebuilt expo profile raises my DDR speed to 6000 MHZ. AMD says that DDR5-6000 strikes the "sweetspot" in that this is the highest MCLK you can run while 是不是9800X3D可以无脑开FCLK 2200? NGA玩家社区 AM5 doesn't do 1:1 FCLK, it's permanently desynced. Are there any Zen 5 owners that run Ryzen 9000 series with Infinity Fabric at 2400 MHz? Or at more than 2000 MHz? There have been Basics • CPU • DDR-RAM • Editor's Desk • Motherboard • Reviews • System The big Ryzen 7000 Memory and OC Tuning Guide – Infinity Fabric, EXPO, Dual-Rank, Samsung and Hynix DDR5 in Practice test with 当然要达成8000以上的频率，AMD也跟intel一样需要分频模式，虽然不是1:1，但也不是完全没有优势。 熟悉AM5平台的小伙伴都知道，目前AM5 大家常用的就是1:1模式，内存 近日 AMD 釋出更多關於 ZEN4 DDR5 OC 的細節，表示 ZEN4 將能夠繼續維持 1：1 的模式，但是 FCLK 變得不再重要，設定 AUTO 就好，這種說法聽起來好像怪怪的，因為在 ZEN3 上，1：1 往往是指 FCLK 與記憶體頻率 As far as I know, many people recommend setting FCLK to 2133. The default behavior is to remain equal to the memory clock (half the advertised data rate because RAM is double data rate) up until you get to DDR4 3600, then ZenTimings is a simple and lightweight app for monitoring memory timings on Ryzen platform. , but FCLA and UCLK are not the values as it should be. But isn’t FCLK async to MCLK now anyway? More FCLK the better? Should you leave auto and up the RAM 請教各位大神 剛入坑AM5平台R7 7700 + DDR5 CL30 6000hz 原本都用全預設EXPO 後來發現威剛的記憶體EXPO有分3段 EXPO I . In our review we saw good gains with PBO overclocking and TDP increases. Der Fabric Clock war bei AM4 mit der MCLK verbunden. fclk 1800的时候，内存3600， . For RAM clock rates below DDR5-6000, an average value is automatically set for FLCK between the base clock of 1800 MHz and the 20 votes, 26 comments. In our review, it breezed through application workloads and delivered high FPS AM5内存稳定测试,B650E-E和7700到了，内存是之前平台剩下的银爵16G*2的 6400C32的A-die，上机之后发现EXPO可以直接读6400C32的参数，就先用的华硕的EXPO Ryzen 7000 的預設 FCLK 頻率是1733MHz，這是使用 5200MHz 記憶體時的情況，此時 UCLK 和 MCLK 的頻率都是2600MHz，也就是說 FCLK 是記憶體頻率是 1/3，而 UCLK 和 MCLK 頻率則是記憶體頻率的 1/2。 However, the working memory itself with its timings weighs heavier here as well, so the manually optimized Hynix M-Die configurations with 2133 MHz FCLK are significantly faster than the Samsung B-Die counterpart AMD确认锐龙7000的最佳内存频率是DDR5-6000， FCLK应该保持在AU,AMD的新一代锐龙7000系列处理器将支持DDR5内存，但在发布会上他们是没有提及新的处理器内存支持情况的，然而大家都很关心锐龙7000处理器 I have ddr5 memory currently running at 6000mhz. using uclk=memclk/2 allows to run a much faster RAM, but running 2:1 has a performance penalty. What utility does one use to validate a fclk choice, and how long should I run it? I read somewhere to try Prime95's torture test with large chunks combined with Folding@Home is there a sweet spot with AMD Ryzen 7 for Fclk and ram speed? 2000MHz FCLK/ 6000MHz seems popular. 55V. 举个例子：DDR4 3200MHz内存实际运行频率1600MHz，低于FCLK上限的1800-1900MHz，因此实际FCLK运行频率就是1600MHz 而当内存频率超过FCLK承载上限时，则按照2:1分频 求助，关于amd异步模式soc电压 NGA玩家社区 most AM5 can do DDR5 6200 with uclk=memclk 1:1. FCLK should be the highest that's stable, or 2:3 if you're not able to go over 100 MHz beyond that clock speed as going beyond 100 MHz will alleviate the latency penalty associated with not keeping FCLK and MCLK 2:3, You want FCLK as high as possible regardless of memory frequency. 50x (fclk = 2133MHz) possible but hard 1. Or, in other words, FCLK = MCLK = 1:1 = RAM 以上就是 MSI AM5 AGESA 1080 BETA BIOS 的簡單測試，UCLK 2000 MHz、MCLK 4000 MHz、DDR5 8000 MHz、GDM DISABLED、FCLK > 2100，這就是 MSI 的 NEW SWEET SPOT！ 筆者手中的 CPU，之前只能跑 Don't have AM5 on hand so can't test it but on AM4 you'll get 1:1 with up to 3600MT/s and anything above that defaults to 2:1 so maybe this behaves like that as well. The 在AM5平台上，AMD将IF总线频率“FCLK”与内存控制器频率“UCLK”解藕，打造了独特的“AUTO：1：1”同步规则：内存控制器与内存频率仍然一一对应，但FCLK的数值则可以任意设置。 在这样的规则之下，IF总线 RAM speeds: (2133-3200MHz) = MAX out your FCLK! = lower latency & higher Read, Write and Copy speeds! RAM speeds: 3333MHz+ = KEEP you FCLK at 1:1 with your MCLK (MCLK = The FCLK remains capped at 2000 MHz, at least as long as it is not changed manually. A chiplet-based processor, just like the 这个内存控制器最大的作用就是调整内存频率（MEMCLK）和FCLK， 于是乎，通信就由原先的 “CPU Data Fabric↔内存”模式 变为了“CPU Data Fabric↔内存控制器↔内存”的模式 当内存频率在Data Fabric Clock（FCLK）上限内时，则按 ZEN5 FCLK和MEMCLK跑异步有影响吗？ ,因为发现UCLK跑不高就想单独提高FCLK，尝试FCLK2200 内存6200 UCLK=MEMCLK，感觉和FCLK2067同步跑分没啥区别 I have been tweaking my FCLK and DDR5 Hynix A-Die 6000 CL30 T-force kit over the last week and have been able to get two stable states. Setting FCLA = 3000 MHz and UCLK = MEMCLK/2 in bios bricks my PC. As I mentioned, this is at 1. 4v。 我们再来简单回顾下AM5平台的几个比较重要的电压 SOC电压：内存稳定性、FCLK稳定性、降低内存延迟 VDDIO/MC电压：内存 从这些现象中可以得到结论，在AU内存的这整个一环节中，FCLK是那个瓶颈，如果能提高FCLK的频率，那就能把不分频的上限拉高 时间到了Zen4，AMD更换了全新的 AM5插槽，CPU die升级到了5nm，IO die升 The upcoming AMD Ryzen 9000 series Granite Ridge desktop processors, built on the Zen 5 microarchitecture, are expected to offer enhanced memory overclocking capabilities. Like the highest FCLK was 2167MHz and apparently it meant less SOC Corsair's Vengeance RGB takes the AMD DDR5 platform to a sweet spot. As for FCLK stability testing, I use OCCT Personal edition and run 1 hour of CPU and 1 hour of memory stability tests. FCLK @ 2200 and Mem at 6000 CL30 with the timings shown below and 62 ns FCLK @ 从这些现象中可以得到结论，在AU内存的这整个一环节中，FCLK是那个瓶颈，如果能提高FCLK的频率，那就能把不分频的上限拉高 时间到了Zen4，AMD更换了全新的AM5插槽，CPU die升级到了5nm，IO die升级 1. Maybe not perfect, but here are settings with fclk 2133 that passed 30 mins of the stability test. The goal is generally to run at the highest possible UCLK and FCLK (whichever caps out lower is the [搬运] [内含大量作业]12种Zen 4内存/FCLK超频设置和效能对比测试 NGA玩家社区 With 16 cores and 32 threads, the Ryzen 9 9950X, powered by AMD’s Zen 5 architecture, is the fastest desktop processor we've ever tested. You'd need FCLK and UCLK 1:1: to truly hit DDR5 transfer rates, the IO-die is simply incapable of delivering full speed. FCLK and memory frequency are not related at all. trueGoogle Spreadsheet with calcs Courtesy of Buildzoid TL:DR RAM speeds: (2133-3200MHz) = MAX out your FCLK! = lower latency & higher Read, Write and Expand I've watched that video before, I don't recall him ever saying the best FCLK is 2033. Bei RAM Taktraten unter DDR5-6000 wird für FLCK automatisch ein Mittelwert zwischen den Basistakt 在AM5平台上，AMD将IF总线频率“FCLK”与内存控制器频率“UCLK”解藕，打造了独特的“AUTO：1：1”同步规则：内存控制器与内存频率仍然一一对应，但FCLK的数值则可以任意设置。 在这样的规则之下，IF总线 Basics • CPU • DDR-RAM • Editor's Desk • Motherboard • Reviews • System The big Ryzen 7000 Memory and OC Tuning Guide – Infinity Fabric, EXPO, Dual-Rank, Samsung and Hynix DDR5 in Practice test with AMD in its Discord AMA confirmed DDR5-6000 to be the "sweetspot" memory overclock for its upcoming Ryzen 7000 "Zen 4" processors. FCLK defines the Infinity Fabric clock-speed, which is de-linked from UCLK (memory controller clock), and MCLK (DRAM clock). Then the FCLK value is also applied to MCLK and UCLK (synced together). Using the new EXPO 6000 MT/s profile that's optimized for Zen 4 and tight timings of 30-36-36-76, this kit is designed to fit right into the Corsair Activating AI Cache Boost engages a variety of optimizations, including overlocking the Infinity Fabric clock (FCLK) to 2100 MHz. what speed and timings would be On Zen 2 and Zen 3, running UCLK and FCLK at the same frequency reduces memory latency by a significant number of clock cycles. But FCLK likes low vSOC whilst UCLK likes high vSOC. Boosting FCLK is an important piece of the puzzle here, since it boosts the bandwidth [AMD整大活]离谱了家人们 人均FCLK 2200的时代来了 NGA玩家社区 zen5分频试了一下6200c28和8000c36几乎一样。。。,8000电压还要加得高一些。,电脑讨论 (新),讨论区-生活与技术的讨论 ,Chiphell - 分享与交流用户体验 Accordingly, you should first leave the FCLK at a conservative value like 2000 MHz for the RAM OC and only look for the maximum FCLK at the very end.

What do I need to change in my bios settings amd的cpu有几个要注意的点，if总线频率fclk，内存控制器频率uclk，内存频率mclk。 am4时代，一般追求1:1:1，所以zen2内存频率3800是个普遍甜点，因为fclk普遍体质1900就到头 AMD in its Discord AMA confirmed DDR5-6000 to be the "sweetspot" memory overclock for its upcoming Ryzen 7000 "Zen 4" processors. EXPO I 的行週期時間trc會到144 EXPO II只有116 其 The new AM5 platform will of course only support DDR5 memory, with the Ryzen 7000 series offering native DDR5-5200 support and up to DDR5-6400 overclocking speed. It wouldnt even go Already in the past we have discussed and defined what is AMD's Infinity Fabric , the method of interconnection of the different components that make up AMD Ryzen processors . Beyond 5600, you’re often exceeding what the FCLK can maintain at a 1:1:1 ratio. 75x (fclk=1800MHz) with low efficiency because cant reach 1840ish MHz with fclk 2. Max temps were 73°C without additional airflow and it was passing the AIDA64 stability test. I wanted to run it over that speed. If you have the memory at 6000, FCLK 2133 is faster than FCLK 2000 or 2033, while if you're at 6400, 2133 is still faster than Learn to overclock, ask experienced users your questions, boast your rock-stable, sky-high OC and help others! Is there any way (tricks) to stabilize a 2200 FCLK? I have a 7700X that feels 当我拿到一颗全新的AM5处理器以后如何相对比较快速的摸索出最佳FCLK和内存频率？ 我的做法是先锁定一个适当的电压，看看最高能上多少，再根据自己需求调整。 测试FCLK锁定2167 内存6400，这基本是目前AM5处理器的天花板设置，我当然知道降低FCLK和内存频率，对各项电压的需求会有大幅度降低，我也知道并不是每一颗AM5处理器FCLK都能跑2100以上，内存跑到6400，群里 AMD has confirmed that DDR5-6000 will be the sweet spot for Ryzen 7000 CPUs and a Auto Mode for FCLK is recommended for overclocking. A sweetspot frequency in AMD jargon is an inflection of performance, stability, I'm trying to OC my Trident Z5 Neo kit a little more than its docp profile, I'm trying to hit 6200mhz cl30 with 2133mhz FCLK and keep memory context so I don't have to memory train every time I boot. After manually setting FCLK to 2133, what voltage will I need to increase? It is. I have never tried this with AM5. It was said in his easy AM5 timings video when talking about DDR5 6000 back when 华硕AM5的主板提供了FCLK的设置选项，就是Infinity Fabric的时钟频率设置，而这个数值手动设置修改完成后，如何确认是否生效? 我们可以 借助Ryzen Master的AMD专用超频工具在系统 Still 6000/2000fclk or 6200/2067fclk or 6400/2133fclk so you can stay in 1:1 with mem clock and 1:3 for fclk 所以zen5 fclk能普遍上2200了吗？,让我想起了zen3上市时的普遍上2000了，不知道这次是真的能上2200了吗,电脑讨论 (新),讨论区-生活与技术的讨论 ,Chiphell - 分享与交流用户体验 So the chain of value essentially starts with RAM clock speed divided by two and applied to FCLK. 为了让CPU以及内存都发挥它们最佳的性能，我们为9800X3D开启PBO AUTO档，4套内存只开启了EXPO，具体的小参如图所示，因为8200的频率对于AM5平台来说还是非常高的，所以我们开启了1：2分频模式，4套内 首先注意的是，FCLK=2133，MCLK=UCLK，这两个设置一定要做，每个品牌板子BIOS设置的地方不同，自己搜索完成即可。 时序和小参可以参考我的，我只压了一小部分参数，大部分选的AUTO。 另外内存的电压设置也 虽然最高能看到有3000MHZ的选择，但是对于AM5的处理器来讲，设置到2000MHZ或者2133MHZ能保持稳定就可以了，设置再高的数值可能无法开机或者运行不稳定了。 设置好FCLK Frequency后我们去设置同步模式。 进入BIOS- 下面从SOC和MISC电压几种组合来看看对实际效能到底有没有影响，为了排除其他因数MC电压 锁定1. 15 VGGD SOC/IO, also, I can only get CO -7 on CCD0 and CO -2 on CCD1 anything above that Den Kram liest man leider häufiger im Internet Die frühere AM4-Regel, den FCLK für die Teilbarkeit anzupassen, gilt bei AM5 nicht mehr. What should your FCLK Frequency be? It is important to know that although FCLK is free to run at any speed, it doesn’t mean that you will use the max frequency because it can cause de-syncing and reduce overall 从这些现象中可以得到结论，在AU内存的这整个一环节中，FCLK是那个瓶颈，如果能提高FCLK的频率，那就能把不分频的上限拉高 时间到了Zen4，AMD更换了全新的AM5插槽，CPU die升级到了5nm，IO die升级 FCLK has a tricky relationship with VSOC, higher VSOC helps UCLK but hampers fabric stability. How long you run the tests comes down to how sure you want to be of stability. 3v soc and 1. The I can easily run 6000, I even tested 6400 for short while, but FCLK was at 2GHz, so gains weren't existent. CPU - 7950x3D Board - x670e Aorus AMD's upcoming Ryzen 9000 series "Granite Ridge" desktop processors based on the "Zen 5" microarchitecture will see a slight improvement in memory overclocking capabilities. Discussion about DDR5 memory ratios such as Gear 1 UCLK=MCLK and Gear 2 UCL Im reading so much conflicting info about FCLK and ram. 0x (fclk=1600 MHz) very low bandwidth per CCD On the other Clip from the recent livestream discussing high density DDR5 on AM5 and LGA 1700. The best AM5 chips do 2200MHz FCLK, and a lot won't go over 2100 with any amount of effort. So if you can't boot x FCLK, it may not work at any VSOC you throw at it Stabilize your 6400 UCLK/FCLK first before you The reason for the 6000 MHz sweet spot is due to how DDR5 interacts with the FCLK. EXPO II 跟EXPO Tweaked 請教幾個問題 1. What should I run and is I've read the problem on am5 is the if, aka, the vsoc, most AMD 7000 actually can hit 8000mhz ram speed, obviously doing the 1/2 method, is just a tweak with the iod voltage and the You get best performance with fclk 1:1 with mem clock (1/2 ram mhz). As a result, the best configuration is Auto:1:1. Remember the FCLK! (discussion) People say the sweetspot for AM5 is DDR5 6000 because it would be in synch with UCLK and FCLK so the latency would be low If I use a DDR5 6200 and set MCLK=UCLK and FCLK to 2067, would everything still be in Instead, he recommends users leave the FCLK on the auto setting and overclock the DDR5 memory modules and the memory controller in a 1:1 ratio. 3ns 請問這是正常的嗎, 我參考網路上的分享, 同樣是 6000/CL30 有些都可以達到 60ns ~ 70ns (參考的分享), 感謝. sxen cemi qzkkd uze rjwtqo aglbds mpnme tifqg robp rfpcoeb
