Unless otherwise described, the following configurations also use these voltage settings. Should I keep my fclk at 2033 for 6000mhz ddr5 ram? I heard that if the ram is running at 6000mhz I should keep the flck at 2033. The goal is generally to run at the highest possible UCLK and FCLK (whichever caps out lower is the limit). For some context, my hardware: CPU: 7950x3D Memory: 2x32GB G. Feb 2, 2024 · Safedisk paired their Ryzen 7 8700G APU sample with a pair of 16 GB memory modules from G. Buildzoid settings w/AIDA results - FCLK question Help Request - RAM So Im new to this and Ive been picking the brains of two people pertaining to this but Im just looking to have some conversation about these timings. Some motherboards break the CPU boost with FCLK 1800+ Bonus3: FCLK overclock depends on the silicon quality of your CPU! The typical range is 1800-1900. 30 The popular monitoring software HWInfo from Martin Malik has been updated to version 7. Mem Clock and U Clock on 3000, but F clock on 2000. Sep 18, 2022 · The launch of the Ryzen 7000 processors brings into the fray the AM5 platform along with next-gen DDR5 memory. Yes, with X670 and Zen 4, 64 GB of DDR5 RAM can actually be run stably at 6000 Mbps. Any help with voltages and/or settings to get 1:1:1 at 6000Mhz? Ram: G. g. On Zen 4, it’s no longer an issue (and actually necessary to hit the speeds DDR5 excels in because the FCLK cannot hit frequencies as high as the theoretical maximum of DDR5). This essentially (nearly) doubles DRAM speeds, outpacing the Infinity Fabric connecting the core and uncore CPU components. Sep 1, 2022 · Responding to DDR5 queries on AMD's Discord server, Hallock said that a 1:1:1 (FCLK:UCLK:MCLK) ratio is not essential anymore. Stable for 1 hour occt ram test. For example, my 7800x3D gains ~250 MB/s when going from DDR5-5600 C28 to DDR5-6000 C30 but gains ~6000 MB/s going from 2000 FCLK to 2167 FCLK. Skill on Tuesday introduced its ultra-low-latency DDR5-6400 memory modules that feature a CAS latency of 30 clocks, which appears to be the industry's most aggressive timings yet for DDR5-6400 Sep 15, 2022 · TeamGroup's Vulcanα (Vulcan Alpha) family of memory modules includes three dual-channel kits: 16GB DDR5-5200 CL38 at 1. I set it as mentioned on default voltage,tested 12hrs overnight and it worked as posted. Here, the RAM speed makes a big difference, but the FCLK clock rate effectively makes none. How long you run the tests comes down to how sure you want to be of stability. For my personal 7800X3D, FCLK can do 2167 MHz while UCLK/MCLK can only do 3100 MHz (or 2000/4000 MHz in 1:2 mode). On Zen 3 and Zen 2, decoupling the FCLK from the UCLK/MCLK caused a latency penalty. 1900 MHz for DDR5-5600. Thus, if we install 3733 MHz RAM, its frequency will be 1866 MHz and the FCLK will become 933 MHz. 3 V. AMD suggested the sweet spot is Ram 6000 and FCLK 2000 ,if you want more I suggest you try FCLK with increments of 25Mhz at a time on default voltage and test until crash and see where you land. Now, I just finished some memory tweaking (all timings/sub-timings). So following Robert’s advice, FCLK should be set to auto, UCLK should be set to 3000 MHz with your RAM running at 6000 MHz. I previously had 1. For RAM clock rates below DDR5-6000, an average value is automatically set for FLCK between the base clock of 1800 MHz and the maximum of 2000 MHz, e. E. e. 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. Sep 27, 2022 · The FCLK is set to 2000 MHz and the UCLK DIV1 MODE is set to UCLK=MEMCLK (1:1). Use AIDA64's cache and latency test and check your own system - sometimes the math is not perfect due to internal mysteries and rounding errors. 1% in the Skyrim benchmark test. Sep 27, 2022 · The DDR5-6000 CL30 configuration is now available in a double version, i. So not exactly same but close. 6000 CL30 EXPO Aggr 1:1 5H16M SR, 2000 IF – “aggressive”, pre-optimized subtimings DDR5-3000 with an FCLK of 2000 MHz and the tightest memory timings you can manage, naturally This still delivers a healthy 48GB/s of bandwidth and the FCLK can fire twice as fast, reducing fabric latency dramatically. ️ Karhu stable for 1 hour too, 3000% coverage. For the very first Ryzen, this was DDR4-3200. This image shows the breakdown of Ryzen 7000's internals. Skill, overclocking the DDR5-7800 C36 modules by 15 percent (DDR5-9000). 2-1. It's not hard to run lower speeds, so if you grab the faster ram its worth testing at least. At the top is the manual Dual-Rank Config with 811. The UMC just refuses to function at 6400 MT/s, even at 1. I did that just now. Previously, I was running with an FCLK of 2167 and an MCLK of 6200. All else being the same, more memclk or uclk always helps. After watch buildzoid's video about the inner workings of zen 2 infinity fabric, I was able to get the system to boot and get the FCLK and UCLK settings to sync in HWINFO by loading the XMP profile, but then setting MCLK to 3533 and manually setting FCLK to 1766. For Ryzen 2000, it was DDR4- The UMC/FCLK are the main issue for this setup. Pyprime was 10. I can't post above 2033 fclk so it's not worth running more than 6000mt/s anyway. 如果zen4 7000系的fclk体质只有2500左右甚至更低 我希望它是能兼容ddr4的,这样之前销量非常高的c9bjz之类的平民法拉利还能继续发光发热. We see meaningful measurable bandwidth changes between e. 4VSOC. Aug 13, 2024 · G. That will vary a lot with your setup (I'm running DDR5@6000, 6200/6400 need more vSOC). Hallock believes that DDR5-6000 will be the sweet spot for Zen 4 based on cost, stability, Aug 31, 2022 · 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. Sep 1, 2022 · Discordコミュニティを率いているAMDのRobert Hallock氏は、最良の結果を得ることためにFCLKの設定を自動にしておくことを推奨し、オーバークロッカーに対してはFCLK：UCLK：MCLKが1:1の比率になるようにすることを推奨しています。 As for FCLK stability testing, I use OCCT Personal edition and run 1 hour of CPU and 1 hour of memory stability tests. so FCLK definitely likes lower vsoc voltage, while ram likes it? Im currently running: 7600x with 2167 fclk, ddr5 6000-28-36-36-48-84 and all the rest tightened. 25v，建议不超过1. Basically, your FCLK should be half of your RAM Clock speed for better performance. A sweetspot frequency in AMD jargon is an inflection of performance, stability, cost, and ease. 2. Sep 27, 2022 · The FCLK remains capped at 2000 MHz, at least as long as it is not changed manually.

Now as per Robert, we now know that the default FCLK for AMD Ryzen 7000 CPUs is set to 1733 MHz. But right now, Newegg is running a sale for GSkill DDR5 6400 CL32 for $219, so I picked up a set of that as well. In retrospect, that probably had as much to do with the processor not stabilizing at 2133MHz FCLK, as well. They reduce latency and often increase effective bandwidth by reducing bubbles of bandwidth loss, even though the ceiling doesn't go up. So at the end of the day it's a trade. 可以看到此时内存延迟62ns，因为SOC等相关电压都给的十分充足，所以在FCLK=2000,内存DDR5 6000状态下的延迟62ns，我认为是比较正常的，这也说明对于X3D来说，即使再烂的内存延迟应该在65ns以内。超过65ns肯定是不正常的效能。 Jan 26, 2023 · Apparently, having a higher FCLK and MCLK doesn't automatically mean better performance. Sep 2, 2023 · Usually you want to prioritize faster memory speeds, but there can be occasions where your memory speed is right on the edge of stability and lowering the FCLK gets it stable, and in those situations where you have to sacrifice 100MHz+ of FCLK for faster memory speed it's better to go for the memory speed lower and higher FCLK (I.
