The default behavior is to remain equal to the memory clock (half the advertised data rate because RAM is double data rate) up until you get to DDR4 3600, then the FCLK will stay at 1800MHz unless you manually set it above that. I OC'ed my RAM yesterday but noticed my FCLK desychronized at anything past 3600MHz. 2 Mar 17, 2025 · The new AMD Ryzen 9 9950X3D and AMD Ryzen 9 9900X3D offer an intriguing value proposition to PC enthusiasts of all kinds. Primarily in AMD’s Ryzen CPUs, FCLK determines the speed at which the Infinity Fabric, the data highway of the processor, communicates internally and with the RAM. Traditionally, the FCLK on G-Series Ryzen processors can clock quite a bit higher than the multi-die Ryzen CPUs and the Ryzen 7 8700G is no exception to that. 1 + 2x16gb dual-rank b-die, atm at 3800c16 I've been trying for hours to find voltage settings that will make FCLK above 1900 possible. Keep this term in mind, it will be important later on. On majority of UEFI builds FCLK should sync to the memory speed, however, you can sync it manually by changing the fabric clock in the UEFI (FCLK Frequency) There is no need to change UCLK as this is the memory controller, and thus synced to the speed of the fabric. This happened when i pressed "Load optimized defaults", meaning i turned off EXPO or any other overclocking setting. I know you’re going to say but 2200 inpossibruh, desync, performance regression, etc. Jun 24, 2015 · On Zen 3 if caused performancedrop.

I can boot at 2033-2066 and maybe higher, but get WHEAs and audio cracking. Equipped with 32 and 24 threads, respectively, they’re primed for fantastic multithreaded performance right out of the gate — and they offer the benefits of AMD 3D V-Cache Technology at the same time. Currently it's set to Auto, I wasn't able to find much info on what speed it puts it at or what the stable range is for the CPU when set to manual. Do the 5600 have weak infinity fabrics or was it just the luck of the draw on the silicon lottery. May 14, 2004 · Memory overclocking has a significant impact on performance of AMD Ryzen-powered machines, but the alleged complexity of memory tweaking on this platform, largely fueled by misinformation and lack of documentation, has kept some enthusiasts away from it. (OCCT, C15, C20, C23, Aida64, Memtest stable) Is there any way (tricks) to stabilize a 2200 FCLK? I have a 7700X that feels right on the edge of being able to pull it off. FCLK or infinity fabric is the bridge between IO and core. Oct 6, 2004 · 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. However, for this communication to happen, there are circuits inside both the CCD and the cIOD called PHYs. To ensure consistency among the tests, we ran our RAM benchmarks three times and used the median May 31, 2020 · AMD Ryzen Memory Scaling Analysis: Introduction Today we are going to tackle a question that spans multiple platforms and CPU generations.

Are there any Zen 5 owners that run Ryzen 9000 series with Infinity Fabric at 2400 MHz? Or at more than 2000 MHz? There have been numerous news posts about Zen 5 supporting IF freq. It acts as the internal communication backbone, dictating how quickly different parts of the CPU and the rest of your system can talk to each other. Running 5800X + X570-I Strix, bios 3602, AGESA 1. 2v 2200 fclk is faster than 2167, above 1. 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 controller and DRAM at 1:1 ratio. On 7800X3D (which has worse memory controller than your CPU), I wasn’t able to get good performance at even FCLK 2100 MHz. Y-cruncher 2. but it's 1/2?no it's 1:1 because DDR means double data As per the title, is there a go-to test for FCLK stability testing?

I got a new Ryzen 7 5800X and it appears to be one with a very stubborn 1900 FCLK hole and boots up to 2000 Fclk with no issues at all. 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 controller and DRAM at a 1:1 ratio. AMD is simply saying that above 3800 will typically require a 2:1 ratio as many Ryzens can't run FCLK above 1900 Mhz. This is no longer the case. 1900 was stable for months even at default auto voltages. On my motherboard (MSI x570 pro carbon), I had to set both infinity frabic to 1867mhz and RAM to 3733mhz in the BIOS. Note that FCLK Frequencies above 2000 MHz may make some internal interfaces unstable. Optimal FCLK frequency can lead to enhanced system performance. Jul 1, 2024 · With the Ryzen 9000 "Granite Ridge," you can expect to run DDR5-6400 with a 1:1 ratio between MCLK and FCLK. Fclk 2200 has no need for a floorlevel soc, but too high soc will cause throttling. Thanks in advance. I have HP V10 16GB (2x8GB) 3200MHz S8B.
