T. but even if i set my ram into the default XMP Profile (3600MHz CL18 @1. 408. FCLK ideally runs at half the memory speed and in sync, as a general rule. Save and exit. O. Step 1. If you have wheas, but system runs stable, please report. Current 130% CPU and 120% RAM. Past 3600MHz, FCLK should be 1:1 with RAM speed. I hope he managed to make the overclock happen it in the end. 1GHz on the CPU all cores. TL;DW: Going for high frequency is a waste of time. We use the alternate MSI MEG Z690 Unify to test memory The easiest might be to load xmp/docp then manually set ram frequency to 3800 for example. Jun 10, 2021 · Running FCLK as high as possible with lower memory clocks does boost performance indeed, however you are better at 1:1 ideally at 1:1 you get the best Latency AND the best performance for example i have 3600mhz ddr4 DIMMS, i have overclocked these to 3800Mhz and set the FCLK and MCLK to 1900mhz - about the highest you can expect on ryzen 3000 May 17, 2003 · Previous setting 1. I must mention the problem is almost certainly not with my RAM since I can run that at 3600 MHz fine, just have to make sure the FCLK is at 1600MHz with that (of course that means it wont be 1:1 and hence I just underclock my ram to 3200MHz usually). Used BIOS to manually set the Adjusted DRAM Frequency (3600MHz), timings (tCL17, tRCDRD18, tRCDWR18, tRP18, tRAS38) and voltage (1. I also have an AMD Ryzen 5 3600X which supports up to 3200MHz as well. I have this processor with 3600mhz cl18 and it is great. The extra cache tends to alleviate the need for low latency high speed RAM. I always recommend the 5900x over a 5800x if the price difference is near the MSRP difference in your area.

Also, it is worth noting that FCLK, UCLK, and MEMCLK are synchronized together which means that they will also be synced to 1800 MHz as well. MoBo: ASUS TUF Gaming X570 PRO Wi-Fi. 4v as it could cause instability. In bios, set bios to recommended defaults, save and reboot. My Rant. In case you don’t know, your RAM speed is measured in “mega transfers per second” and the frequency it runs at is half this value because two bits are transmitted per clock cycle, e. Or 3600mhz. 35V) and You want the FCLK frequency to be half the rated speed of your RAM. Ryzen 5800x FCLK 2000mhz. I would at least like to run 3600 at stock (suggested) timings at 1:1.
