By default if you run your RAM at speeds up to 3600 MHz the 1:1 memory to IF ratio will be used so your IF will be running at 1600 MHz if your memory is running at 3200 MHz (because the true frequency of DDR RAM is half of the the advertised speed (which should be measured in mega transfers not megahertz but not many people care about that these days . If you have a lower MHz ram (starting from 2133 up to 3200MHz) you SHOULD overclock your FCLK in order to lower latency and increase read, write and copy speeds! Did I somehow made that not clear enough? Oct 30, 2023 · It generally takes an additional 100mhz on the fclk to make up for de-sync the FIFO buffer by not running 1:3; which is generally only viable for improvement at 6200mhz for memory. 47V, highlighting its excellent overclocking potential. This image shows the breakdown of Ryzen 7000's internals. I now have 2x48Gb Corsair 5600Mhz and whenever i try to sync the FLCK, meaning using 2800mhz, the PC doesn't boot anymore.

They limit the memory performance potential. Dentro de la parte de «OC Tweaker» encontraréis, en la sección de DRAM, Infinity Fabric Frequency and Dividers. I've run TestMem5 on this and it seems stable. It operates at a 1:1 ratio with the memory clock, ensuring optimal performance. JEDEC spec 3200 is not good though. 4v SOC, it will crash if I test stability with Prime95 Large FFTs and OCCT VRAM test simultaneously. 3600MHz is the sweet spot and any higher will only give like 1-2 FPS more, not worth it in my opinion. Jan 27, 2020 · By default FCLK, UCLK and MEMCLK are still synced together on 3rd generation Ryzen for speeds up to and including DDR4-3600 (1800 MHz FCLK/UCLK/MEMCLK), and as a result users with DDR4-3600 kits By doing 3800Mhz you make the infinity fabric of your CPU run at max it can ( half the DDR4 speed - so if 3800 ram then 1900FCLK) while if you run 4000Mhz -FCLK will run at 1000Mhz only - so much slower ! FCLK cant run at 2000Mhz so it will halve itself - hence 1000Mhz only. Jun 5, 2023 · In Zen 2 architecture, FCLK frequency is tied to the memory clock speed. started using a latency calculator a few hours ago and I'd get better latency with lower RAM clock speed with tighter timings. Hey guys. 1-1. Ahí podréis cambiar el FCLK. Most samples I've tested will run FCLK 2200, but as always YMMV. So not exactly same but close. If the FCLK frequency is lower than the RAM frequency, it can create a bottleneck and limit Jan 10, 2021 · That should give you the full performance of your RAM. According to Asus specifications for this laptop "DDR5-4800 SO-DIMM, Max Capacity:32GB, Support dual channel memory", but the processor specifications indicate that "Supports up to 256GB DDR5-5600 RAM". Also, it is worth noting that FCLK, UCLK, and MEMCLK are synchronized together which means that they will also be synced to 1800 MHz as well. For the very first Ryzen, this was DDR4-3200. It nets ~64ns in AIDA64. Apr 30, 2024 · We found that this RAM model has an impressive clock speed of 6000 MHz and a latency of 10 ns (30-38-38-96 timings). I would bring the SoC voltage down a bit, typically 1. You can try overclocking your RAM but I would focus on overclocking the timings rather than the core clocks. Apr 17, 2022 · TLDR Don't use CPUz to test if FCLK and DRAM is synced use Ryzen Master Hello, so I overclocked my PC and it was running at 1:1 and some time passed and I checked CPUz and even after lowering the clocks to 3200mhz ram and FCLK to 1600 it goes 1:16 instead of 1:1 while I have set FCLK === MEM CLOC On Zen 4, running UCLK and FCLK at the same frequency provides no memory latency reduction. The Ryzen 5000 series can achieve an FCLK frequency of up to 2000 MHz. Now, let’s discuss the connection between FCLK frequency and 3200MHz RAM. I have simply increased the memory frequency to 6400 as well as increase FCLK to 2133 and set "UCLK DIV1 MODE" to "UCLK=MEMECLK". Would I be better off setting my FCLK to 1866 for better performance or should I leave it at 2033? In the future I will upgrade to 6400 Mhz at which point I'll run the FCLK at 2133. Start by entering your BIOS settings and finding the FCLK frequency alternative.

However, that is actually the correct ratio for 4000MHz RAM, because it's not actually 4000MHz. 而当内存频率超过FCLK承载上限时，则按照2:1分频. DDR means double data rate, which is to say you get 2 transfers per clock cycle. Most people are running 1900 something something or under. There is no such thing as "base FCLK". Zen 3 architecture introduces a decoupling feature similar to Intel’s approach. I also managed to push this RAM kit to 7200MHz using 34-40-40-105 timings at 1. And you're absolutely right in the end a lower frequency with tighter timings has less latency. In testing 6400 at 2133/2200 fclk, there is little to no difference in latency while there is a moderate improvement in memory read and write bandwidth. It is recommended to use RAM at such a higher MHz speed that the Infinity Fabric can keep up. Hallock believes that DDR5-6000 will be the sweet spot for Zen 4 based on cost, stability, performance I'm running this config (2x32GB) at 5600CL28 with UCLK:MEMCLK 1:1 and FCLK 2200.

Like most other elements of your computer, the RAM can often be overclocked as well. FCLK = 3:3:2. So there is not point imo to buy ram above 3600mhz . I'm surprised how much timings impact both memory and CPU performance - more so than just a straight FCLK/MCLK increase. Jan 7, 2022 · The FCLK can barely hit 2000MHz in most cases on Ryzen. Feb 14, 2021 · En este caso, en el menú denominado OC el FCLK Frequency se encuentra en la parte de configuración de la RAM (DRAM Setting). Sadly too many google searches about RAM tell people that DRAM speed is more important than RAM timings and people end up buying 4600Ghz+ RAM that cost like $400. D. Primary timings like tCL really don't mean crap at this point outside of marketing, it's the sub-timings that matter more for memory performance; you can have a ~CL30 kit lose to a tuned CL40 kit because of terrible sub-timings. O. For Ryzen 2000, it was Jul 11, 2023 · The unit used to measure RAM speed is megahertz (MHz). We've been tunning some tests on Zen 3 - and you can replicate these - but the most important part is ensuring that UCLK and MEMCLK are 1:1 with each other, and that FCLK is some neat ratio.
