Maybe 8000MHz RAM can give this bandwidth so any higher inifinity fabric only helps for ccd-ccd communication bandwidth and single-thread / single-ccd performance. skill 64GB (2 X 32GB) 6000MTs CL32 ripjaws s5 dual sided ram. RTX 4090. May 13, 2024 · 6000CL30 EXPO Tweaked, tRFC tightened, FCLK bumped 2200, everything else in EXPO. Jul 11, 2023 · In conclusion, the FCLK frequency is a critical factor in optimizing the performance of a computer system, especially when using 3200MHz RAM. These profiles define the RAM's voltage, frequency, and CAS latency so that it can run at faster clock speeds compared to the standardized frequencies. I'm looking for 64GB of the best performing RAM in low profile (for the NH-D15), in two sticks so 2x32. You can change your‌ FCLK frequency through your Jul 26, 2021 · DDR4-3200 is still the officially supported memory frequency on Ryzen 5000. Only today I noticed this change goes together with the FCLK: The BIOS sets it to 1200 MHz for 2400 MHz and 1600 MHz for 3200 MHz. I noticed when the FCLK was set to auto in the BIOS, the speed reported in HWInfo was 1600 and the UCLK was 900. Edit3: can't get past logon screen with 16-17-16-16 May 15, 2023 · 第二：目前电压下的fclk=2200其实并不是最佳的电压设置，其实并不稳定所以导致了延迟跟fclk=2000没啥差别。 退一步把fclk降到2133，可以看到内存延迟会稍微降到61. I spoke to a rep from Asus about my MOBO only to learn that these sticks aren't on their list of supported memory. MCLK/MEMCLK = Memory clock. 3800 is quite high for 1:1 mode although 11900K’s can do it without too much hassle. I used to have 3600mhz ram (2x32gb) for which i'd set the FCLK to 1800mhz for a 1:1 ratio. If you’re running 3600MHz RAM, your FCLK should be set at 1800MHz. 18,695. Some test examples from Zen 3: Apr 30, 2024 · Capacity: 32 GB (2 x 16 GB) Frequency: 5200 MHz. 18,535. If you want to run higher frequency and enjoy adjusting, tuning memory you can run up to 6600MTs 1:1 ratio. Posted January 15, 2021. 1v. For instance, an FCLK frequency of 1800MHz is achieved by setting the multiplier to 18 when using a 100MHz base frequency. I compare gaming performance between stock AM5 settings and AMD's recommended settings. Troubleshooting. I see that some AMD official advice is to use 6000mhz RAM with the new 8700G CPUs, also for other latest generation AMD CPUs. However, the actual "Best" possible configuration will always be the highest FCLK matched with the highest memory frequency possible in a 1:1 Ratio. My system: Ryzen 5 3600 stock settings Asrock X570m Pro4 (bios ver 3. But the thing is that on AMD's product page for the 8700G, the supported RAM speeds are: Max Memory Speed. Using the new EXPO 6000 MT/s profile that's optimized for Zen 4 and tight timings of 30-36-36-76, this kit is designed to fit right into the Corsair ecosystem to provide a great end-to-end user experience. Memory: 2x32GB G. Besides, higher frequency RAM has higher bandwidth. P. Jan 15, 2021 · 7. 4 when running the RAM at 6200 MHz if you have Hynix memory chips. The Auto:1:1 ratio refers to FCLK:UCLK:MCLK. For RAM clock rates below DDR5-6000, an average value is automatically set for FLCK between the base clock of 1800 MHz and the maximum of 2000 MHz, e. ago. The APUs are a different beast though, the 4000G series should do Normally when you enable XMP it sets your FCLK properly unless its over DDR4 3600, but in this case it should have worked. qp np fd kf gw no au zw ml ed
