I noticed in CPU-Z that the Northbridge (NB) frequency was exactly half of what the memory clock (MCLK) was. 39v. Now the optimum config is to run FCLK at 2000, basically a 3:2 divider. I would say that a very high frequency with a lower CAS rating would obviously be the best. Cool stuff You also have to keep in mind the coupling with infinity fabric, max clock speed, 3GHz, which makes the ddr5-6000 the optimal candidate. Hm, always kinda wondered how it worked. 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. Wonder if they’ll support higher frequency memory or focus on redesigning their infinity fabric to hit 3000mhz. Going higher (like the 6400MHz sets that Intel shipped with their review packages) would mean the infinity fabric would like to be clocked higher and reviewers mentioned that the CPU's really don It's sorta like, 5200MHz is basically "guaranteed to work at full speed", whereas anything above that is not. It's slightly off because the CPU base clock isn't exactly 100. technically yes, and Intel 12th and 13th gen scale tremendously with memory speed in gaming performance. 395，VDDQ给的1. 25 V VDDG CCD, 1. 15 V VDDP voltage are used here.

Enabling AMD EXPO inside the BIOS is “technically” overclocking. RAM: 32GB G. Also the "cas 14" means 14 clock cycles, in a context of a frequency. The memory controller on Zen 4 can't actually handle high frequency ddr5 kits, if it goes above DDR5 6200~ it'll actually reduce infinity fabric clocks. 3000MHz is not possible on FCLK, that is much too high. The problem is I dont see where I can change that and I coudnt find anything on google. Consequently, there can no longer be a 1:1:1 config with DDR5-6000, as there was with Zen 3. The infinity fabric is not wide enough to move additional data gained by having memclk higher than FCLK as both channels have the same 64B/cycle width. The weird thing is Windows 11 is running no for 5 hours with crashing. Still makes no sense though, since no AM5 CPU supports DDR4 and DDR5 like intel's chips do. Default/auto Infinity Fabric setting is 1,800 (ryzen master shows Coupled Mode OFF). 0 so AMD needed to make the Infinity Fabric 50% faster per clock. Memory: G. But there is a option called 'Infinity fabric frequency and dividers', which can manually Jul 21, 2024 · DDR5 6000 = 3000MHz, so the FCLK should be at 2000MHz.

Skill 6000MT/s DDR5 PSU: Corsair RM1000x Case: Coolermaster Operating System & Version: WINDOWS 11 Pro GPU Drivers: 23. UCLK is the frequency of the unified memory controller UMC. The default Auto option sets UCLK=MEMCLK/2 which seems to be causing Key takeaway from this video: AM5 does not report WHEAs for correctable infinity fabric errors, in contrast to AM4. 4) Under the heading "Boot" do the following. As I understood it you want to keep the ratio between infinity fabric clock and RAM clock as simple as possible so 1:1 would be the most optimal but since the infinity fabric clock cant get much faster than 1900MHz when overclocking it at least for the Ryzen 3000s. All are 1,600. Skill DDR5 64GB 6000Mhz Trident Z5 Neo (F5-6000J3040G32GX2-TZ5NR) Voltages: VDDIO / MVDD / MVDDQ: 1. Anytime you see it listed as MHz, it's technically wrong. Picking "auto" in the BIOS will automatically aim for that setting. Can anyone help ? But I have come across the term "infinity fabric" regarding RAM speeds. 6, isn't it supposed to be 3200 now? in HwidInfo, my fclk (inf fabric clock) = mclk (memory clock) = uclk (memory controller clock). Jun 9, 2020 · I understand that XMP profile can let me achieve the targeted 3200 mhz (currently set to 2666 mhz). 2 Description of Original Problem: I have enabled XMP on the RAM to run at the advertised 6000MT/s and my understanding is the infinity Fabric should ideally be half this. Gear 1 is generally the best but for high memory overclocks not always possible. 5x, 2. The nb/uncore frequency is the infinity fabric, it is running 1:1 even though it's 4mhz off. 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. 35V VSOC: 1. Clicked memory into the motherboard and on the first try set 4000 MHz 16-16-16-36 & Infinity fabric @ 2000 MHz without even touching any voltage. 1. Unless you could push the ram to 9000MHz, you will just get diminishing returns On Zen 3 you'd want to run Infinity Fabric in sync with memory, but this isn't possible anymore, because FCLK can't reach 3000 MHz (assuming DDR5-6000 memory). Aug 16, 2023 · 1833 through 1967 (and possibly others, didn't check) are available through "SMU Common Options" -> "Infinity Fabric Frequency and Dividers" but they don't work for me. After rebooting, my DRAM Freq is still 1599. In conclusion, Zen 4 also breaks with some of the conventions of previous Zen CPUs in terms of tuning. Intel supports a much higher range of frequencies. The bundled ram can be EXPO’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. MCLK is the ram frequency. 29) but it wasn't fully stable. The 2000 MHz Infinity Fabric Frequency (FCLK) is also automatically set together with the RAM profile, so everything is theoretically done with one click for the average user. Nov 3, 2022 · This means that the Infinity Fabric is generally maintained at 2000MHz while the memory controller runs at 2400MHz for DDR5-4800 or 2600MHz for DDR5-5200 or 3000MHz for DDR5-6000. 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. 6 MHz (which seems correct for 3200 DDR RAM), but the NB frequency was only 799. 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. But without network cable connected. 10. a) Set "Full Screen LOGO Show" to "Disabled" Forums - Linus Tech Tips A number of reviews compared 7700X at DDR5-6000 CL30 because AMD recommends it, even compared to 13700K running DDR5-6400, seemed unfair but the infinity fabric is problematic for AMD on speeds outside the range it's designed for. 40V] BCLK Frequency [100. unfortunately there is a very high chance AM5 is going to be bottlenecked by the infinity fabric, so there may not really be any benefits to running memory clocks this high. Gear 1 on ddr5 is NOT going to happen. 0 as Zen 3 has would not provide enough bandwidth at these frequencies for DDR5. Note that DDR5-6000 refers to 3000MHz or 6000MT/s.
