Ordering one-on-one infinity fabric material.
Ordering one-on-one infinity fabric material.
I looked through many online sources about the Ryzen 3000 and compatible RAM. I discovered a feature called “Infinity Fabric” that AMD uses to find the optimal RAM speed and latency. AMD shared a diagram for their Ryzen 3000 models, indicating that the ideal balance was around 3600MHz and CL16. I purchased g.skill TridentZ Neo DDR4 RAM with CL16-19-19-39 1.35V, which the packaging claims is built for top performance on the X570 platform. After updating the BIOS, I found options like FCLK and Target FCLK, but I’m unsure what to adjust. The Memory Frequency setting is currently set to ‘Auto’ and suggests a target of 2133MHz, though I can manually change it to values like 1333MHz or 6000MHz. The FCLK is also set to ‘Auto’ with a target of 1200MHz. I see that the DRAM voltage is listed as 1.35V, matching the box description. I can’t change the auto settings, so I’m wondering if altering these parameters will help. It seems confusing whether adjusting them affects stability or performance. I’m trying to maximize RAM speed without risking damage, so I need guidance on the best approach.
Search for XMP/DOCP settings to achieve the advertised 3600Mhz performance on your CL16 RAM, and ensure the infinity fabric synchronizes perfectly with the RAM in 1:1 mode. With an ASUS board, XMP/DOCP profiles will appear in Easy Mode when you enter BIOS on the left middle section.
I'm glad to help! I didn't know about the D.O.C.P. option, but after checking, it's available in the AI Overclock Tuner. Setting it to D.O.C.P. updated the FCLK and 1:1 settings, which resolved the issue properly. Thanks!
It seems the NB frequency needs to be doubled. That would mean running at 3600Mhz with a clock speed of 16 MHz. Great!
Check the XMP profile settings for your 3600mhz/CL16 memory on the Asrock X570. Confirm it's set to 1:1 and verify with Automagic if it's functioning correctly.
You're considering memory kits for your Infinity Fabric system. You're weighing between the G.SKILL Trident Z Neo DDR4 3600 and the 3800 models. The 3600 offers a 2:1 timing ratio, while the 3800 provides a 2:1 ratio as well but with different timings. Since you mentioned avoiding a 2:1 ratio, the 3600 might be your safer choice. You can check compatibility and performance with DRAM Tool to see if you can adjust timings for the 3800. As a beginner, it's good to start with one kit and monitor results.
Maintain consistent ratios and latency targets. Prioritize low CAS latency around 16. Exceeding 3600 offers minimal benefits on Zen 3.
