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 Also yeah, wether you use the igpu or not, ryzen does love faster ram and lower latency since how infinity fabric works. You may get a minor bump in FPS, which by the way the human eye drops efficiency at around 120mhz on the screen. Anything higher will have negligible higher efficiency results. 0 MHz (x 2 = ~3000 MHz) and Task Manager to show a speed of 3000 MHz (up -3600mhz ram kit and get great performance without touching a damn thing. Note that you do still have some leeway to change these values even when sticking to the 1/2 RAM rule. 35V), as well as FCLK Frequency (1800MHz), and UCLK DIV1 MODE (UCLK==MEMCLK) Or Userbenchmark is part of the long list of services that erroneously show RAM frequency wrong. Based on the list, CPUs and Supported Memory Frequency. The higher the RAM frequency, the faster it can transfer data to and from the CPU. lower latency is "faster". Press F10 to save and hit enter cross fingers it takes. If we take the same 3800 spec and just increase the frequency to DDR4-4000, which right now in the absence of 2000 MHz FCLK support decouples from a 1:1 ratio with the Infinity Fabric, we A memory frequency of at least 6000Mhz is advisable. 2. Jun 21, 2021. And the FCLK frequency, along with values derived from it, may change as your overclocked RAM . 3 5V" In BIOS under MEMORY FREQUENCY this reads "DDR4-3200MHz" FCLK FREQUENCY reads "1600MHz" and yet I'm still only getting Despite the fact that my UEFI was showing the memory at 3600 MHz, no application in Windows reflected that. Your auto settings were correct. The penalties of decoupling are probably more of a Fclk = half memory speed or 3200mhz ram = 1600mhz fclk for example It will run coupled up to 1800mhz (3600mhz ram) after that it automatically decouples and you need to set it manually for higher ram speeds your RAM speed is measured in “mega transfers per second” and the frequency it runs at is half this value because two bits are Also realize that '3600MHz' and '4000MHz' run at memory clock frequencies of 1800MHz and 2000MHz respectfully. 3rd Gen Ryzen can run different clock for Fabric Clock and Memory Clock. If you need to run CL18 or CL20 timings for DDR-3600might as well keep it at rated DDR4-3200 CL16. Unlike zen3, for zen4 IF wil not be at 1:1 but 2:3. 422.

Ryzen 5000's FCLK is a lot more forgiving, paving the way for a 2,000 MHz FCLK but when set FCLK to 1900 in bios memory controller clock is right to 1900mhz as FCLK too (hwinfo) REEDIT : 75ns for FCLK 1800 vs 64ns for FCLK 1900 , read 46k vs 50k, well i think its done -R5 3600 4. That being said, I would go with 16gb of DDR4 3200mhz CL16. 3200MHz RAM and 3600MHz RAM both have a capacity of up to 64GB. 3600MHz is the sweet spot and any higher will only The FCLK is measured in megahertz (MHz) or gigahertz (GHz). Faster 3866+ memory is on the QVL for 2X16GB kits but we're well north of $200-300. FCLK Frequency For 4000mhz In Zen 2 architecture, FCLK frequency is tied to the memory clock speed. 4 volts. Posted January 4, 2021. Ram 1500 Service in Waterloo, IA. Sort by: RaptaGzus. DDR4-3200 16-20-40-1. So I loosened the timings a bit and I can do 4333 stable at CL20, but 4400 just isn't stable unless I drop to CL22. 3800 cl16 kits may not run optimally if your ryzen CPU can't handl 1900mhz on the IF/FCLK. If the RAM clocks do not match the FCLK, then it will go 2:1, effectively halving the performance of your RAM. Specs: 11700 | RTX 3060 Kinda, the way it works on Zen is actually a little different. only difference between slots is tRDWR and tWRRD i think. Gradual steps. Find out what RAM ICs (Thaiphoon Burner. 2ghz 1. I just upgraded to 3600MHz RAM, however I realized that the board is only specified to support up to 3200MHz. Some games do show huge gains so it No 3600mhz kits. UCLK is the memory controller frequency, and that is synced with the memory frequency. The tight timings. When the FCLK is decoupled from the MCLK you suffer around 9ns of latency penalty which cannot be overcome under normal conditions except for the most extreme of ram speed (something like 4600mhz or above with good timings like 16-16-16). Discussion. i. Hallock believes that DDR5-6000 will be the AMD guarantees up to 3200MT/s ram so 1600Mhz fclk. 99) You don’t have to spend much to obtain premium RAM that is optimized for Ryzen. basically 1/speed * clocks [*2] = latency. If everything is updated and the RAM is in the good slot try with the XMP profile at auto but you change the speed manually to 3600MHz. FCLK plays a critical role in determining the overall performance of a CPU. I'm very happy to increase DRAM voltage to 1. 18v - 1080ti Gigabyte Aorus 2126mhz - FlareX 3200CL14 B-die at 3600mhz 16 16 16 16 32 48 TRFC 288 - MSI B450 So not exactly same but close.

Hello, Last week I upgraded my RAM to Kingston Fury Renegade 16GB 3600Mhz CL16, and I turned on XMP profile, everything was working The FCLK frequency is typically set at a default value that matches the memory’s speed, but many computer enthusiasts and gamers are discovering that It is recommended that you run the FCLK at half the speed of your RAM clock speed for the best performance. fclk. OC it to 3800mhz if you're keen. So a 3200mhz cl16 and 3600mhz cl18 are the same latency. Save and exit. So following Robert’s advice, FCLK should be set to auto, UCLK should be set to 3000 MHz with your RAM running at 6000 MHz. I would go with this. Corsair Vengeance LPX 16GB DDR4-3200. However, there's very Probably better spending your time trying to get 3600mhz Ram working, should be not too hard most 3000mhz kits can run 3600mhz on ryzen, As far as I am aware the fclk should sync with your RAM, the only reason why it would decouple is if you stretched your ram past the 3600mhz/1900 fclk. 2. FCLK Frequency For 2400mhz Ram. Try moving the RAM. You need to manually overclock to get 3600mhz if using more than 2 sticks. Distinguished. Which reads "D. T. There may be instances where the FCLK may be set to operate in an “asynchronous” mode (not a 1:1 The board and cpu can probably handle 3600mhz with no issues. This is not a good setting for performance but is for testing only. Put in 64 gig (4x16) of 3600mhz cl17-19-19-39 Once I got W10 pro up and running, after some updates and reboots and just generally seeing things working, went into the The Infinity Fabric clock speed (FCLK) is configurable and directly relates to the memory clock (MCLK). Personally I like 3600 cl14 more because you can keep the IF/FCLK frequency at 1800. The spd tab also says the max bandwidth(1066MHz) while my ram is running at 1799. However, changing the DRAM Frequency in UEFI to 3000 MHz caused caused CPU-Z to show an 'Uncore Frequency' of 1497. 168. For example, if the memory runs at 3200MHz, get the fclk frequency for 3600mhz ram. So apparently at the end Kingston memory KIT There is some benefit to the upgrade you made, as not only do you have more memory bandwidth, but the FCLK can go higher now. So 3600MHz is doubtful.

There is no such thing as an 'odd' frequency - standard RAM speeds actually go up in 66's and 33's like this - 3000 - 3066 - 3133 - 3200 - 3266 - 3333 - 3400 - etc, etc. 4V. However, in practice you should just manually set the IF to 1800MHz if you're running 3600MHz on RAM anyway, because it takes you 3 seconds to set it up, and it's better than booting to the In our content creation tasks, the effects of this overclock were small but measurable, with the 3800MHz RAM and 1900MHz infinity fabric combination outperforming our 4000MHz RAM in the Cinebench Ryzen 3000 series can work with memory speeds way above 3600 MT/s but will lose performance if decoupled from the infinity fabric clock. A warning message came up about how my fclk frequency should be 1:1 with it to avoid issues or damage or something. The easiest might be to load xmp/docp then manually set ram frequency to 3800 for example. 6MHz? I am using the msi cpu-z version as I am using the msi x570 pro motherboard and the normal version doesn't work correctly. This RAM comes in a 2-module kit with a Also check the FCLK and UCLK ratio settings, should be 1800MHz and 1:1. Now I guess I either need to overclock the FCLK or underclock the DRAM frequency. Kia. 400v safely but if 1. But now, with XMP on they are still running at only 3200MHz. Good enough for now, need to come back to this later and experiment with other voltage controls to keep that 2000 freq Hi, now it's correct. png. Soc voltage can help with fclk, shouldn't exceed 1. Short for Extreme Memory Profiles, XMP defines a set of configurations embedded into the RAM SPD in addition to the standardized profiles approved by the JEDEC. tRFC will likely go to 300 with this bin at that frequency/voltage without issue.

My 5600X did just fine with 2x16gb dual rank sticks at 3600mhz (even when OC'd to 3800), but it has "0d" coldboot issues with 3600 c16 in a 4x8gb config with single rank sticks. DDR stands for double data rate, meaning the RAM is actually running at half of what it says it is (3600mhz = 1800mhz in reality). It's stock max is 1800Mhz, but it can sometimes be overclocked up to 1900Mhz if the silicone is good enough, or even maybe something like 1933Mhz if you have a golden chip. ATTEMPT 2 - I changed FCLK frequency to 1900Mhz, enabled overclock, If I have 32gb RAM, I can only go up to 3600Mhz 2Rx8(2R meaning dual rank I believe), which is probably why if I go above 3600 MHz my memory frequency ratios no longer match. For instance, an FCLK frequency of 1800MHz is achieved by setting the multiplier to 18 when using a 100MHz base frequency. Or, in other words, FCLK = MCLK = 1:1 = RAM frequency/2. Should I just leave that alone or raise it to match the memory Examples of FCLK Frequencies. 3600MHz is the recommended for Ryzen because 1800MHz is sort of the default for the FCLK. As the official site states the memory controler is for 3200mhz max will I encounter any problems and should I juat go for the 3200mhz option? FCLK is linked to memory speed, you want the highest possible FCLK. xmp. • 2 yr. Beyond that you run the risk of Fclk not being stable at your selected speeds, and also just overspending for really marginal performance gains. Ryzen 5800x PBO/CO - DDR4 3600mhz OC'd to 3800mhz - FCLK 1900mhz - MCLK is the true memory clock, double it for DDR speeds. C. Why is FCLK 3200Mhz? Shouldn't it be 3600Mhz? 3.

Reply reply first i had a 5800x which was running my 3600mhz cl 16 ram just fine 1:1 1800 out of the box I have been paying attention to my voltages with each fclk frequency. Fclck was set manually to 1:1 in all cases, my 5800X Fclck is stable to Judging by his posts, I suspect he hasn't manually set FCLK, so he's at 2000 MHz memory, 1000 MHz UCLK, and 1800 MHz FCLK If you want to tune memory frequency, aim for DDR4-3800 or DDR4-3733, and follow any Ryzen memory OC guide. 2 and 3 will probably be very similar if not the same, it depends on the motherboard (daisy chain 2 is better, T topology 3 is better). PS. The Connection between FCLK Frequency and RAM Speed. mas se possivel, tente subir tanto as memorias para pelo menos 3600mhz (com FCLK 1800) Ai sim você terá um ganho expressivo de desempenho. Cheaper is better ~$150 or less. FCLK on most chips Overclocking to DDR4-3733 provides a nice performance boost, but only if you’re able to stably do it with synchronized UCLK and FCLK. We bumped the FCLK Frequency up to 1966MHz to keep the DRAM and FCLK Frequency on a 1:1 ratio to maintain the highest performance advantage. For example: You want the FCLK frequency to be half the rated speed of your RAM. This is a really cheap g skill ripjaw 16gb kit of 3600mhz ddr4 ram. Leaving everything else to be set by "Auto" gives these voltages and timings: This RAM will boot at 3866, but it will fail large Prime after a few minutes, so I think there is a little more room in it. Bonus2: Keep in mind the high voltage bug of FCLK on some BIOS versions. 5000 Series: 3600-3800 Optimal, 4000 Max. And I realy don’t think your system The Ryzen 3000 & 5000 series "Sweet Spot" for RAM Speed is 3600Mhz. You only buy those high-frequency kits if you want sticks binned at those frequencies. Click to expand Yeah there in the correct slots and bios is updated as well. Before I wasn't able to POST FCLK 1900 without RAM OC even. So i actually had tp lower RAM frequency from 3800MHz on ZEN 2 to 3600MHz on ZEN 3. Then the FCLK value is also applied to MCLK and UCLK (synced together). RAM speeds: 3333MHz+ = KEEP you FCLK at 1:1 with your MCLK (MCLK = 1/2 of RAM speed) Bonus: in depth video. I have tested 2 samples of ryzen 5600g and both can run ram fclk : mclk 1:1 at 2266, resulting dram frequency of 4533mhz. Jul 18, 2018. So if I can run 3800MHz ram and 1900MHz FCLK on a Ryzen 5, 3600MHz ram on a Ryzen 9 should be no problem. I'm currently sitting on the B550i, 3700X, and I'm looking for a 2X16GB kit, NO RGB!, low profile DOCP 3600mhz Cl16, 16-19-19-39 or 16-16-16-36. Upgraded so far: Ram: Corsair Vengeance RGBPro 32GB 3200 Mhz - CMW32GX4M2C3200C16. Many people buying new systems go for DDR4-3600 memory as that is the most beneficial overclock for this generation of CPUs. If it boots check windows event viewer after loading some games/apos, if you get loads of WHEA19 errors try 1866fclk, if same try 1833fclk. 5 or So 2200MHz seemed like a reasonable goal, that would allow me to go up to 4400 MT/s on the RAM. Ram speed doesn't do much at all for Intel cpus as it does for Ryzen, which sees over 10% performance gain using 3200mhz ram or higher. Actually Hardcore Overclocking. This RAM comes in a 2-module kit with a 32 GB capacity, which is Yeah it should be perfectly stable with DOCP mode (i. Best RAM for the AMD Ryzen 7 5800X CPU Base Frequency 400–1067 MHz 800–1600 MHz Effective Frequency 800–2133 MHz 1600–3200 MHz Voltage 1. Oct 20, 2013 1,765 113 Memory and FCLK frequency. Zen 3 architecture introduces a decoupling feature similar to Intel’s approach. And RAM needs to be overclocked to reach its rated setting anyway- for instance a kit of DDR4-3000 would be running at 2133/2400/2666MHz out of the box, and would require an XMP/D. Latency: 10 ns (CL16) Timings: 16-20-20-38. The "Sweet Spot" is where Ryzen performance will be at its optimum by RAM Speed. Hallock believes that Our RAM was able to hit 3933MHz versus 3600MHz, maintaining the same Voltage and timings. If your RAM has a good die (Samsung or Micron B/E-die), just ramp up the DRAM voltage to like 1. XMP Enabled, 3600mhz will not post unless i use 1 stick. Like most other elements of your computer, the RAM can often be overclocked as well. Just want to get the highest possible memory frequency and then work on the timings. 3 you need to check if the motherboard can handle 3600mhz. This is what Amd claimed. The advertised speed is the transfer rate in MT/s, not the frequency. It's not a RAM kit as I bought them individually in different time frame) New RAM: 2x Corsair Vengence LPX 8GB DDR4 and Oh Boi, that's one hell of a beast! Clicked memory into the motherboard and on the first try set 4000 MHz 16-16-16-36 & Infinity fabric @ 2000 MHz without even touching any voltage. What is the difference between this two options and am I If you have more money and want the best gaming performance then look for 3600 cl14 or 3800 cl16. not BIOS. Yes 3600mhz ram will work with both of those CPU's. But I'm not the RAM-Yoda. Upcoming AGESA work will make this easier. I have never seen a report of someone not being able to run 3600/1800 on a 5900X or 5950X. Looking first at Shadow of the Tomb Raider on the Intel Core i9-10850K you can see how marked the trend is. for example if you have two sticks of 3600mhz ram set the fclk to 1800, fclk should be half of dual channel ram speed as far as i know unless it’s beyond I also changed the ,,XMP High Frequency Support" from Auto to Level 3. My RAM did 3800 14-14-14-28 with 1. I’m running Crucial E-Die 4000mhz CL18, it’s the ballistix Max rgb kit. 1800mhz FCLK. When I check CPU-Z, I get changing the DRAM Frequency in UEFI to 3000 MHz caused caused CPU-Z to show an 'Uncore Frequency' of 1497. With AMD Ryzen you want to set the FCLK half of your memory speed, so when using, for example, 3600mhz then set the FCLK to 1800mhz. In the BIOS, I have (I think) enabled XMP Profile 2. Zen 2 and Zen 3 APUs Can do +4500 Easily with 1:1:1 Ratio. 49V, so lower CL but also slightly lower frequency. People suggest 3000/2000/3000 is the dream settings for DDR5 6000, and it is. I have ONE profile selection under D. 0 (BIOS version F4) CPU: AMD Ryzen 5 3600 Cooler: Scythe Fuma 2 Thermal paste: Arctic MX-4 RAM: Crucial Ballistix 3600MHz CL16 16GB GPU: RX460 15/08/2022. 0. CPU: Ryzen 5 2600 - 3400 Mhz 6 Core. Ultimately, the best bang for buck option is 3600Mhz , cl16, 1800Mhz Fclk. Well. Depends on your motherboard's specs concerning RAM speeds and the Motherboard's I've tried a 5600x, 5800x, and now a 5900x with a 2000 fclk/4000 RAM and I'd get slight audio super . The important thing is to keep memory frequency and FCLK in 1:1 ratio for best performance. Disclosure: This post may contain affiliate links. qrzgtzfuxfnfsflagsxn
