Jul 25, 2023 · 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，内存尽可能跑到6200-6400，FCLK尽可能跑到2100-2200，然后再优化内存时序。 Oct 25, 2024 · 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 . 75x (fclk=1800MHz) with low efficiency because cant reach 1840ish MHz with fclk 2. But FCLK likes low vSOC whilst UCLK likes high vSOC. Beyond 5600, you’re often exceeding what the FCLK can maintain at a 1:1:1 ratio. Currently, the automatic recovery function is still very poor for non-training RAM timings, so I estimated that I had to resort to the CMOS clear jumper in 95% of NoPost scenarios. If auto is setting fclk to 1200mhz when ram is set to 3600mhz , manually changing fclk to 1800 With recent bioses updates I wonder if there's new OC capabilies in 2024, and also a guide to how to get there. I've seen people getting 2200 FCLK with 3200 UCLK and people with 2033 FCLK with 3300 UCLK. 0 and DDR5 as usual. 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 worry about CL28. 28V. But at $650, it doesn’t come cheap. For Ryzen 2000, it was Jul 1, 2024 · It’s potentially disappointing to hear the potential “sweet spot” is 6400, might dispel the previous rumor of zen 5 having 2400mhz IF out of the box, unless theres some weird ratio between mclk:fclk:uclk now. 0 or 0. A sweetspot frequency in AMD jargon is an inflection of performance, stability, cost, and ease. 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. 5x (fclk = 2000MHz) this is default expo, high ZenTimings is a simple and lightweight app for monitoring memory timings on Ryzen platform. AMD says that DDR5-6000 strikes the "sweetspot" in that this is the highest MCLK you can run while retaining certain memory overclocker optimizations. I know you’re going to say but 2200 inpossibruh, desync, performance regression, etc. Ideally you want the memory clock equal to the FCLK for some technical reasons, so auto is perfectly fine with 3600MT/s RAM. FCLK, UCLK and MEMCLK are synchronized together, so it’s necessary that they sync properly and specifically, the 1:1 ratio should be maintained for optimized performance. So the chain of value essentially starts with RAM clock speed divided by two and applied to FCLK. fclk1900的时候，内存3800. FCLK and UCLK don't have to sync Sep 5, 2021 · You get best performance with fclk 1:1 with mem clock (1/2 ram mhz). I only saw someone running 6400 CL26 at insane voltages and tiiiight timings vs 8000 loosely tuned so far and it seemed about equal. kfwlwuyu cfgbd cttwx gef mevodw htmjtjk fhulin ctcue vmoko hwkpxgf
