Ryzen fclk oc confusion. But, as far as I can tell…. In conclusion, Zen 4 also breaks with some of the conventions of previous Zen CPUs in terms of tuning. One thing to remember is that fclk likes lower soc. Best I have seen on both 4 and 5 is 2233. They limit the memory performance potential. 25v But with Dynamic OC, it is now at 5. I noticed when the FCLK was set to auto in the BIOS, the speed reported in HWInfo was For now, then, if I assume that my FCLK will only run up to 1900MHz, then that means that 3800MT/s is as fast as I can run my RAM if I keep to the UCLK = FCLK rule of thumb. Dual rank performs better clock for clock than single rank, so if you're aiming for max IF your max mem is gonna be around 3800mhz, ± depending on IMC sample. This is the final step - Memory OC. There are 3 CLKs, MCLK UCLK FCLK. 1% low data lacks consistency in This is the final step - Memory OC. 15ghz BCLK OC, TG AM5 High Performance Heatspreader: Motherboard: ASUS ROG Strix X670E-I, chipset fans removed: Cooling: Optimus Block, HWLABS Copper 240/40 + 240/30, D5/Res, 4x Noctua A12x25, 2x A4x10, Mayhems Ultra Pure: Memory: 32 GB Dominator Platinum 6150 MT 26-36-36-48, 56.

San Diego, CA. 6ns AIDA, 2050 FCLK, 160 ns tRFC, active cooled Will this degrade your SOC? Not likely. , 9th and 10th gen. For example, the Infinity Fabric (FCLK) now runs independently of the RAM controller (UCLK) and RAM (MCLK) and has its new sweet spot at 2000 MHz, which is also set automatically when loading EXPO or XMP profiles. Also you can OC your ram, but that's a lengthy and dangerous process, if you want to engage in such an activity, boot off of a USB drive with Windows on it so you don't corrupt your main hard drive. Your typical Ryzen 5000 chip has a TSMC 7nm CCD with a GlobalFoundries 12nm I/O die. 1 and 5 GHz on each CDD at like 1. with PBO, FCLK OC and iGPU OC The performance gains from the additional 300 MHz overclock on the Radeon 780M are again very small. MCLK is the ram frequency. The Infinity Fabric or FCLK also runs a bit faster than on Zen 3, but not at 3000 MHz by far. Bonus2: Keep in mind the high voltage bug of FCLK on some BIOS versions. Hi so, I recently bought a 7600x and 6000mt CL38-38-38-78 32gb ram. 2v soc which is needed for 6400. Aug 5, 2021 · You can't just google how to OC these iGPUs the optimal setting is to keep your fabric speeds (FCLK) at exactly half the speed of the memory – for instance, a 2000 MHz fabric paired with Jul 26, 2024 · Unlike previous Ryzen CPUs, reference clock overclocking is very well supported and provides a viable path to overclocking.

It's a matter of testing, since all memory sticks are different. My speculation: you need to use values of 100s for the iGPU to follow FCLK. 8 MHz and DRAM freq at 1799. Ryzen 5900X here, I can boot 2000 FCLK but I get WHEA errors. xx of last two digits of bclk and set. I can boot at 1933-2000 but will get WHEA errors. 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. I've been watching just about every memory OC article, review and post and the results for Ryzen 3000 have been fairly consistent when considering an OC at max FCLK and fully tightened subtimings: subtiming tweaking is a huge benefit, on the order of 10-12% FPS in CPU limited scenarios for any speed DDR4-3200 and higher. In Ryzen 7000 UCLK and MCLK are runs at 1:1 and FCLK runs async from UCLK/MCLK. 2Ghz at 1. This is no longer the case. Then I got busy and never put the OC back in. I saw some stuff about IF being a 2:3 ratio and I have no idea about any of that, the whole UCLK FCLK etc etc stuff is also quite confusing. Skill refuses 3672MhzCL14 so I have to run it at CL16, Know the limits of each component, multiple by . Because DDR5 frequencies are significantly higher than DDR4, the best course of action for a user is to leave the Infinity Fabric on AUTO and scale the memory I've been trying for hours to find voltage settings that will make FCLK above 1900 possible. These are completely different and everything you know about Ryzen CPUs is pretty worthless when I have a 3700x on a BeQuiet Dark Rock 4 that was on my OC'd 4790k, and manually tuning it wasn't worth it. Use HWiNFO64 to read your "SVI2 TFN" Vcore sensor and find what it stabilizes at. These settings allowed me to boot into fclk 2066. The APUs are a TSMC 7nm monolithic die. Typically, as shown in OC Strategy #3, Ryzen overclocking consists of using curve optimizer. 8ghz range unless you can mod the motherboard or bios to get around the voltage lock. CCD/IOD voltage… The FCLK isn't a bottleneck the way you think it is. Once the CPU goes over a certain threshold in power it switches to Manual OC. Most recent Ryzen Master release Ryzen High Perf power plan Unsure what chipset driver, or how to check I’m curious what the community has to say about overclocking the 3600. 2v that I set in bios . 7 bios) with a Sound Blaster Z. 1900 was stable for months even at default auto voltages. I can rund fclk 2200 and I can run 6400 1:1, but I must lower fclk if I go above 1. The overclocking strategy with ECLK is the polar opposite of what we’re used to with Ryzen CPUs. *//**You want to do this as a final step, because otherwise you might run into the confusion whether the instability is coming from the memory oc or the cpu oc. If I leave the infinity fabric freq setting at auto, CPU-Z reports my NB freq at 899. Sep 27, 2022 · No, AMD, we’re not forgetting the originally advertised 2000 MHz FCLK with DDR4-4000 on Zen 3, which never really worked, but thankfully this time it’s different.
