OC'ed it to 3733MHz (optimal for ZEN2 according to AMD), latencies to 16,19,19,19,39 and got 67,1ns latency and almost the same read/write/copy speeds. The results will most likely get closer with BIOS updates. As far reduced bandwidth, there are several Dec 31, 2021 · I somewhat understand RAM however I am unsure if a Jump from 3200Mhz CL16 to 4000Mhz CL18 will give me extra performance? Doesn't Ryzen get faster with higher speed RAM. UCLK is the "UNCORE" clock. 45v, though I Dec 22, 2020 · DDR4 3600MHz vs 4000MHz. Dual rank RAM is great for performance. 41. UCLK==MEMCLK. Jan 9, 2021 · From what I understand, the FCLK and frequency of RAM should match to maximize the performance. 40V 32GB (2x16GB) Ripjaws V series DDR4 DRAM memory is designed for sleek aesthetics and performance, making it an ideal choice for building a new PC system or for upgrading your system memory. Set the FCLK manually in Bios. I got G. In upcoming AGESAs, we will be implementing additional tuning that will make reaching 2000MHz easier. Here are some AIDA memory results: A) 3733MHz CL14-15-15-35 (XMP def, only lowered to 3733MHz); IF: 3733MHz, 1:1:1 Ryzen 5800x/ Asus rog strix x570-f / Patriot Viper Steel 16GB (2x8GB) DDR4 4000MHz Dual Channel. Ryzen CPUs will default to a value that's dependent on the speed of Jun 30, 2022 · So i just got new RAM after figuring out my current sticks were not compatible with the ASUS TUF Gaming X-570-PRO Motherboard. Millions of transfers. Just got a Gskill Trident neo 32gb 2x16 4000 18-22-22-42 kit, running on a 5800x3d with an Asus b550 gaming-f motherboard. I'm trying to decide on my RAM based on speed/timings. Nov 6, 2020 · Posted January 4, 2021. • 5 yr. FREE Delivery. Jan 7, 2022 · The FCLK can barely hit 2000MHz in most cases on Ryzen. Mar 3, 2021 · It's similar to how the FCLK works on Ryzen processors. 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 At a ram speed of 3200MT you want 1800mhz fclk. It doesn't hurt the RAM to run async, but it does hurt your performance, knocking anywhere from between 15-25% off the top. 2ns at stock XMP. Stability Testing. 33. The RAM kits being introduced don't differ all that much from already-available kits. You're talking about MCLK, and most Ryzen 5000 will only do 4000MHz+ if it's asynchronous from FCLK (because of what I wrote just above), and then performance drops again. However, I read somewhere that "AMD suggests 4,000 MHz RAM is the sweet spot for low latency and high performance ". Edit: Just reread your post. Skill with different IC's as an example. 35V Nov 5, 2020 · G. May 28, 2021 · I've built my new setup: CPU: Ryzen 9 5900x. Well. Best Overclocking RAM For Ryzen 9 5950X: TeamGroup T-Force Xtreem ARGB 3600 MHz. After this, lowering RAM voltage a bit if possible. Gives you the fastest stable FCLK and RAM speed at 1:1 with low So yes there is a limit, usually around 4000mhz ram, you can run it desynchronized higher but it takes a hefty latency hit. Even after selecting the XMP profile to 3200 mhz and FCLK to both auto and 1600 mhz, I am still seeing the ram is running at 1330 mhz . ( Ryzen CPUs are safe up to 1. Good enough for now, need to come back to this later and experiment with other voltage controls to keep that 2000 freq Oct 15, 2020 · According to the leaked official slide, AMD is suggesting DDR4-4000 MHz system memory clock speed to be the sweet spot for all Ryzen 5000-series Zen 3 desktop processors, and DDR4-3800 MHz the Jul 8, 2019 · X370/X470 BIOS is still immature when using Ryzen 3000 (depending on the board) Highest achieved memory frequency was 4333 MT/s on X570, 4200 MT/s on X470 and 3666 MT/s on X370. But for 2nd Gen Ryzen, FCLK and MCLK are synchronous. JEDEC spec 3200 is not good though. FCLK on most chips should max around 1900MHz so optimal mem clock is 3800MHz. 55 Jan 27, 2020 · By default FCLK, UCLK and MEMCLK are still synced together on 3rd generation Ryzen for speeds up to and including DDR4-3600 (1800 MHz FCLK/UCLK/MEMCLK), and as a result users with DDR4-3600 kits The board and cpu can probably handle 3600mhz with no issues. Best Value RAM For Ryzen 9 5950X: Lexar Hades 32 GB RGB LED Lighting 3600 MHz. . DDR4 Profiles. Buy at own risk, these are always huge gamble, don't be surprised if you can't even POST anything above JEDEC. As discussed in earlier speed comparisons, RAM speed benchmarks for 3600MHZ, 4000MHz, 4400MHz, and beyond have shown that there begins to be diminishing returns for gaming. Testing 4000MHz RAM: Are higher I got my Ballistix Sport LP 2x16GB 3200C16 E-die Memtest stable at 3600C16-19-16-36 at 1. At 1867 MHz, it was giving WHEA warnings, so I just upped the VSOC to 1. 15v and 1. The kit includes 2x32GB DDR4-4000MHz sticks of memory with an XMP/D. Server: AMD Athlon PRO 3125GE, 32 GB 2667 MHz DDR4 ECC, TrueNAS Core 13. Aiming to run the kit at 3800 with fclk at 1900 and decent timings that are stable for gaming. 4v. Some CPU's or chipsets limit RAM speed AM4 kind of tops out at 3600 (can OC past but hit and miss) and some intel chipsets limit the max RAM speed. To better understand the FCLK frequency for 4400MHz RAM, let’s consider a few examples. Aug 31, 2022 · For the Ryzen 3000 "Zen 2," it climbed to DDR4-3800, the Ryzen 5000 "Zen 3" it was DDR4-4000. This is bad, the latency penalty outweighs the additional memory bandwidth. XMP 3000. Skill and Asus, an overclocker known as Bianbao has set the new world So I switched it back to 1800 and overclocked my ram to 3600mhz :D. GrapLYT. A Hz is a tick, DDR memory transfer up and down every tick, meaning 1600Mhz = 3200MT/s. fl dn kv vb gw qc gh xf zw dr
