Your best bet is to scour the overclocking forums and compile the information. 4) Under the heading "Boot" do the following. So the memory controller is much better than Intels in that it can run dual rank configs to at least 6000 mt/s, and it seems to run pretty tight at single rank 6400, comparable to Intel platform, but then it completely shuts down single rank above 6400 mt/s. But I have come across the term "infinity fabric" regarding RAM speeds. 0 so AMD needed to make the Infinity Fabric 50% faster per clock. So I hopped back into BIOS, manually set IF to 1800, and rebooted. Nov 3, 2022 · With previous Zen, memory clocks above 3600MHz would result in a divider being applied to the Infinity Fabric clock, thus reducing its effective speed and imparting a significant latency penalty. 8M subscribers in the Amd community. If I am only looking for the best bang for my buck between performance and stability, what OC settings would you recommend for me? Disclaimer: I am completely new to all of this. 25 V VDDG IOD and 1. Both FCLK and memory frequency should be matched for the best latency. Just step up your memory frequency, keeping all your timings loose enough that they won't be a problem and ensuring that your mclk & fclk & uclk (memory clock, infinity fabric clock, and memory controller clock) remain at 1:1:1 ratios. For example your ram is at 3600Mhz (that is in real Life 1800MHz because it is double data rate (ddr) and your Flck is at 1800 you run it at 1: 1 "Officially supported" memory speed is 5200, but the sweet spot is 6000 which will run the Infinity Fabric 1:1 ratio. Default/auto Infinity Fabric setting is 1,800 (ryzen master shows Coupled Mode OFF). DISCLAIMER. 25 V VDDG CCD, 1.

FCLK Frequency seems to run at 1800MHZ by default and has no effect on the actual IF clocks. I think the 3 relevant settings are system memory multiplier, infinity fabric frequency and dividers, and UCLK DIV1 MODE. BTW, DDR means double data rate. set it to 3,600 megahertz. I never got this configuration to work. BZ recommends Y-cruncher VST for validation, but I figure you might still need to performance validate infinity fabric overclocks as you will not get WHEAs telling you that silent errors are affecting your performance. Consequently, there can no longer be a 1:1:1 config with DDR5-6000, as there was with Zen 3. Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon… 1. Infiniti fabric clock is the speed of your cpu is communicating with your ram, if you will. As for A die, it is $$$, for personal gaming PC, in my opinion definitely not worth it. Note that DDR5-6000 refers to 3000MHz or 6000MT/s. Modern SSDs connect to the CPU via PCIe through the infinity fabric. 30 The popular monitoring software HWInfo from Martin Malik has been updated to version 7. Of the two, frequency matters more because it’ll increase the responsiveness between cpu cores and with the ram but if you can get tighter timings as well, go for it. Does it need to be in line with CPU frequency or something? My cpu was at 4800MHz roughly. Gear 1 is generally the best but for high memory overclocks not always possible. This may go out the window with zen 3 though. 8 MHz, which did not make sense to me, because my understanding is that MCLK should be equal to the NB frequency/FCLK. 27v CPU core 3400mhz~3350mhz (one CCX is at 3400mhz and all other ones are at 3350mhz) OC 3900X, 16~17~17~35~75~1T 1600mhz (3200mhz) Corsair Vengance 2x16+Gb, Fclk (Infinity Fabric frequency) is at 1600mhz.

Memory timings are referring to this clock. Oct 30, 2023 · FCLK is the Infinity fabric, that seems to need to be within a certain multiplier range of the MCLK - any value dividable by 0. The fix is to go into BIOS and set Advanced -> AMD Overclocking -> Accept -> DDR and Infinity Fabric Frequency/Timings -> Infinity Fabric Frequency and Dividers -> UCLK DIV1 Mode -> UCLK=MEMCLK. JZ-Electronic. Something like the Hynix M die to me is a good alternative that is cost effective and performs well. Get the Reddit app Scan this QR code to download the app now Infinity Fabric Frequency and Dividers, set frequency to 1/2 your XMP speed If your ram is 3200MT I started by applying XMP and leaving Infinity Fabric Frequency and Dividers at Auto, assuming this would set IF to be coupled to DRAM and be assigned 1800. 29) but it wasn't fully stable. Any idea why? My system is stable at 2,000 Infinity Fabric, but I can't figure out why a massive drop in CPU performance. Infinity fabric clock is automatically set to be equal to UCLK, though it can also be manually set to something else as you please. Interesting that they mention trying their Hynix a-die (that worked well over 7000 mt/s on z690,) but it doesn't work above 6400 on x670. 85 votes, 32 comments. I downloaded CPUZ to check what the frequency curently is of the infinity fabric is and its at 1200. When a core needs to get data from RAM, or from a neighboring core, it has to go through the IF connection. So the fabric lets all the chiplets communicate ultra fast and behave as though the four 4-core chiplets are a single 16 core cpu. I don't understand at all what the right settings should be. If Infinity Fabric scaled greater than 2P, this would be an even bigger deficit for Intel (but going for 4P+ would have been an insanely risky move for AMD). SOC voltage, infinity fabric frequency and dividers removed. 15 V VDDP voltage are used here. Can anyone help ? Key takeaway from this video: AM5 does not report WHEAs for correctable infinity fabric errors, in contrast to AM4. Ahí podréis cambiar el FCLK. Double check in CPUZ if you aren't sure. 6, isn't it supposed to be 3200 now? in HwidInfo, my fclk (inf fabric clock) = mclk (memory clock) = uclk (memory controller clock). HWInfo 7. 0 as Zen 3 has would not provide enough bandwidth at these frequencies for DDR5. There are 3 CLKs, MCLK UCLK FCLK. Using Infinity Fabric 2. My machine for example runs in Gear 2 (1:2) because my DDR4 is running so much faster than the 3200 MT/s Alder Lake officially supports for DDR4 and it can't stay stable at Gear 1. 30 just the day before yesterday and with it many new features for Ryzen 7000 CPUs and X670(E) or B650 Get the Reddit app Scan this QR code to download the app now Infinity Fabric Frequency and Dividers (inhale) panel. Blck is at 100mhz multiplied per CCX accordinly (34x for the best CCX and 33. I frankly have no idea what impact it would have on real world performance, but messing with PCI-E link speed is known to cause NVMe data corruption so be careful. The advertised speed is the transfer rate in MT/s, not the frequency. Core Performance Boost and TSME added 2. 40. As always, DDR stands for Double Data Rate, so a 3200MHz DDR4 kit is more accurately said to have a 1600MHz clock and a 3200MT/s data transfer rate. Sep 18, 2022 · The below chart (via: @harukaze5719, from Chiphell) shows the ideal fabric speed when paired with DDR5-6000 RAM: The above AIDA64 MemTest was conducted with the memory and IMC in a 1:1 (MCLK: UCLK) configuration and the Infinity Fabric frequency adjusted between 1500MHz and 2166MHz. Unless that changes, no, because dual and quad channel memory run at the same frequency. 3600 is a sweet spot because zen 2 infinity fabric often can’t go above 1800 and benefit from a higher ram frequency. My RAM should be able to achieve 6000MHz. I think there's a memory controller issue in some Ryzen 7000 CPUs which is why they state that i A full AMD CPU has a communication substrate called infinity fabric and 2-N of these chiplets tossed on top of the substrate. 2400 CL12 and 4000 CL20 both have the came CAS latency of 10 nanoseconds; scaling the tick count isn't causing a penalty if you're also raising the frequency too.
