Sadly too many google searches about RAM tell people that DRAM speed is more important than RAM timings and people end up buying 4600Ghz+ RAM that cost like $400. The last is to prevent the CPUs memory controller to downclock when increasing the RAM clock. So for Zen 4 the ratio is 2:3:3 (FCLK:UCLK:MEMCLK). Run 3800mhz, try some loose timings like 18-22-22-22-46-68, leave everything else on auto and make sure you're stable at that frequency before trying to bring timings down. skill 6k RAM on Asus TUF 670e board. When you only have a single RAM stick, you’ll be running it at half speed (single channel), and this is where even relatively modern standards like DDR3 can start seeming too slow for intensive tasks. Note the FCLK bridges. The actual clock of the RAM is 2000MHz, with 4000 MT/s (megatransfers). Jan 28, 2014 · I see that some AMD official advice is to use 6000mhz RAM with the new 8700G CPUs, also for other latest generation AMD CPUs. started using a latency calculator a few hours ago and I'd get better latency with lower RAM clock speed with tighter timings. Oct 20, 2023 · My personal journey into the world of FCLK frequency overclocking was a rewarding one, offering tangible performance gains and a deeper appreciation for the intricacies of computer hardware. 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. 25V might be required. ¡No lo confundáis nunca con el FCH BCLK que aparece justo arriba! ASRock. FCLK and UCLK are both 2,000 MHz. If I manually put it to 1600Mhz to match memory clock I'll get more performance right?

Start by entering your BIOS settings and finding the FCLK frequency alternative. 3 V SOC voltage. 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. For example I you are running 3600mhz ram set your fclk to 1800mhz. Slowly increase the FCLK frequency in little increments, screening system stability at each action. I'm surprised how much timings impact both memory and CPU performance - more so than just a straight FCLK/MCLK increase. Apr 30, 2023 · I used to have 3600mhz ram (2x32gb) for which i'd set the FCLK to 1800mhz for a 1:1 ratio. However, if you still want to get the maximum performance out of the platform, at least turn the FCLK to the stable maximum of 2167 with 1. By default if you run your RAM at speeds up to 3600 MHz the 1:1 memory to IF ratio will be used so your IF will be running at 1600 MHz if your memory is running at 3200 MHz (because the true frequency of DDR RAM is half of the the advertised speed (which should be measured in mega transfers not megahertz but not many people care about that these days . If you have a lower MHz ram (starting from 2133 up to 3200MHz) you SHOULD overclock your FCLK in order to lower latency and increase read, write and copy speeds! Did I somehow made that not clear enough? Oct 30, 2023 · 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. My MOBO supports RAM overclocking, as well as OC profile uploads. Now, let’s discuss the connection between FCLK frequency and 3200MHz RAM. 64fps: 4000MHz CL16 (FCLK 1900MHz) 489: 5083: 37. DDR means double data rate, which is to say you get 2 transfers per clock cycle. Each memory speed has its own optimal fclk, which is why I'm Dec 24, 2022 · This means that if you have a DDR4 RAM clocked at 3600 MHz then your FCLK frequency should be set to 1800 MHz for optimal performance. This is because there is a latency hit when the FCLK and MemCLK are not divisible / proportional, as data has to be waiting for the next "tick" to transfer across the pipeline. Apr 17, 2022 · TLDR Don't use CPUz to test if FCLK and DRAM is synced use Ryzen Master Hello, so I overclocked my PC and it was running at 1:1 and some time passed and I checked CPUz and even after lowering the clocks to 3200mhz ram and FCLK to 1600 it goes 1:16 instead of 1:1 while I have set FCLK === MEM CLOC On Zen 4, running UCLK and FCLK at the same frequency provides no memory latency reduction. I suspect there's nothing different with the physical hardware. It is recommended to use RAM at such a higher MHz speed that the Infinity Fabric can keep up. Aug 31, 2022 · There's no "one size fits all" ideal fabric frequency. I have simply increased the memory frequency to 6400 as well as increase FCLK to 2133 and set "UCLK DIV1 MODE" to "UCLK=MEMECLK". Hey guys. I have an ASUS TUF Gaming A15 FA507XI, with Ryzen 7940hs processor. Like most other elements of your computer, the RAM can often be overclocked as well. Zen 3 architecture introduces a decoupling feature similar to Intel’s approach. The faster the RAM, the more CPU performance you get with Ryzen CPUs.
