I'm thinking of upgrading the CPU to a 5700X and the RAM to 32GB when the Zen 3 processor prices drop (hopefully a few months after the new Zen 4 processors release). Having more bandwidth (on either cache or RAM) brings effective latency down as well, because it reduces the amount of time that the transfer itself take to complete after it has begun. Also notice on the crappy 5600mhz its 1. My understanding is that Zen 2 (3000-series) would reliably hit ~1600MHz IF, but that faster IF speeds were hit or miss—this is why the recommendation was DDR4 3200MT/s. Sep 9, 2021 · Question RAM speed vs timings. The 2x4 GB Frequency and bandwidth both play a role in determining RAM speed. Data is sent on the raise and fall of the clock cycle making the actual operating clock speed differ from the effective clock speed. Lately I've been seeing much discussion on various tech based subs on which type of ram is superior, what the ideal frequency for ryzen 3000 is, how much you should spend on ram, and other questions of that nature, yet it seems very difficult to actually see in depth how timings + frequency affect gaming performance, as the topic has just recently surfaced to the mainstream - likely Maybe I will loose the timings and try to tune the memory to see if I can get 4000. When that happens the transfer can begin in 1/5'th to 1/20'th of the time and the transfer speed can be 10-100x greater. We looked into how these speeds impact performance in gaming at four resolutions and a wide range of application workloads. I've never heard of any Ryzen CPU that couldn't manage 3200.

I have 4400mhz CL19 DDR4 ram and benchmark speed of 46,000MB/s. When choosing RAM, consider specs in this order: Budget: How much you can spend will be your first limitation. Frequency matters a bit more because it gives you more room to play with, but it's like 60/40 frequency/timings. 4v. The formula is clean and easy when you use GHz for the clock speed. The sweet spot for most AMD CPU's is 3600mhz as it meets 1:1 ratio on the AMD memory controller. The infinity fabric speed goes up/down depending on ram speed, even if decoupled. The 3200mhz is the highest non overclocked speed RAM the board will support but will support up to 5100mhz OC'd (whether manual or automatically using memory profile). When I checked the timings, they were all set to Ryzen Master settings even though my manual inputs were set. Even if I use the XMP timings (3600) on my Micron E Die. 3200MHz is a second less ideal optimization point but more beneficial than any other RAM speeds except 3600 MHz. We determined that this DDR4 RAM provides a solid balance between speed and latency, making it ideal for users who want excellent performance without Well the only 2x8 3800 cl14 kit listed on PCPartpicker is $240 and it's a Neo kit which seems to be focused on Ryzen systems. You might get like 1-2 FPS difference in games tops. What I have been doing is playing around with timings of the memory and can definitely tell you that overclocking a Ryzen gives less performance boost than over clocking RAM and tweaking the timings. Highest rated speed supported being 3200mhz is because that's the "official" highest speed for DDR4, but ryzen does higher clock speeds no worries at all. lazy RAM tweaking 101, lol I think our RAM has Hynix E chips on them . First make sure whatever RAM you get is on the approved list from the mobo vendor or is known to work at its rated speed/XMP on Ryzen. eventually i bought a 5700 sapphire pulse. There is no easy fit for everyone. The registry, correct me if I'm wrong, had no bearing to the bios. Would it be worth also going for higher memory speed/tighter timings on the memory kit? I'm using an Asus B550-F Board, Ryzen 5900X CPU, RTX 4090 and 2x 16Gb Kingston (Hynix) 3200Mhz (CL22) ECC Ram in my System. Timings are important, but speed more so. Skill as well. For chiplet based Ryzen you need to find where the infinity fabric clock (FCLK) maxes out, and that varies chip to chip because of silicon lottery and different RAM setups such as, 4 sticks, single/dual/quad rank, more capacity, type of IC, motherboard topology, BIOS' ram support. Jun 24, 2020 · So at the moment apart from niche RAM kits and tweaker's paradise E-Kits, B-Die RAM is the most favored as it allows an easy overclock of the RAM and tightening (lowering) of the timings. In your example 3200CL16 is faster than 2666CL14 because there's lower latency/higher speed. So, if you're a set and forget person, 6000 is the sweet spot. The timings need to be tight enough to offset the drop in Some people have gotten things working well at 6200 and6400, but it's dependent on the memory controller being able to match the memory's speed, and being able to run a higher fclk, although it's asynchronous so it's not critical. Remember actual clock speed is half the DDR speed rating. What the BIOS does is it takes a preset listing of the RAM list it has internally in the firmware, and then matches the frequency to what is on the list. EDIT: Despite the seemingly now common opinion that RAM clock speed is more important than timings on Ryzen, AMD's own research shows otherwise. I believe this is due to Ryzen liking even timings. Or overclocking RAM might be easier with one or the other. Most people will use stock settings. I run my 2x16Gb 3200 1. If you research the impact of RAM speed on throughput, there seem to be countless Youtube videos on this subject, you might wonder what all the real word fuss is about once your ram clocks pass 3000 and particularly 3200. Tuning memory timings can have large improvements in games, on average 30% vs default 2666 mhz memory For DDR5 and Ryzen 7000, the RAM speed tops out to 6000. Just wanting to know if it will make a noticible difference on the iGPU performance for Ryzen APU, i know the RAM speed is relevant, but not how much. Whether you see some improvement (not measured by eye) depends on the game. Still not on par with Samsung B-dies (since those can slam down primaries like nobody's business if decent bins) but in some timings such as tRCD, tRAS, tRC and tRFC, it beats out Micron E-dies considerably to compensate for CJR/DJR's lower max clock speed potential (not much of a problem on Ryzen systems though due to FCLK being tied to it). Aug 22, 2020 · Digital Foundry investigates whether RAM speed affects fps for gaming on AMD Ryzen, and what's more important: frequency vs timings. What RAM Timings Mean In addition to standard speed ratings, each RAM module also has a rating for something called timings. Dec 18, 2020 · On Ryzen 5000 – just like Ryzen 3000 – the memory clock, the Infinity Fabric clock, and the memory controller clock are all automatically locked in a synchronous 1:1:1 ratio from DDR4-2133 all the way up until DDR4-3600. And it has a direct impact on bandwidth and latency. If I had to choose between DDR4-3200 speed with 16 CAS Latency and DDR4-3600 speed with 18 CAS Latency, what should be my priority? Should I focus on lower CAS Latency or higher RAM speed for optimal gaming performance, particularly for minimizing input lag? Aug 8, 2019 · Finally, the TridentZ Neo also in the out of the box spec at 3600 MT/s, a 3800 MT/s overclocked configuration using the XMP timings, and then a max OC configuration at 3800 MT/s with manual timings. 4000MHz RAM would be a pretty big hit to RAM performance. Even at 6500 MT/s and pretty good timings (some are lower than yours) I'm only getting 86GB/s. Sep 5, 2019 · stub Memory speed on Ryzen has always been a hot subject, with AMD’s 1000 and 2000 series CPUs responding favorably to fast memory while at the same time having difficulty getting past 3200MHz Additionally, high end ram is more about the IC's you get, and the binning of them as opposed to the XMP and DOCP profile speeds. As for slower speed vs. The currently installed ram is DDR4, 3200MT, 1Rx16, CL22. You can always go higher RAM speeds, but you're getting diminished returns on value, because the FCLK dictates your RAM entirely. I can buy a 2x8 cl14 3200 Trident Z RGB kit for $160 but it kind of seems silly to "upgrade" from my 4000Mhz kit to a 320 Oct 3, 2024 · The maximum speed at which you can run PC memory depends on your CPU, motherboard, and the memory itself. The fact that your having this problem, i 100% know its something different than your ram and cpu, since your ram has ran the speed before, and your cpu definitively supports it. Skill Apr 29, 2020 · The 'best' speed for a 3600 is the same as for any Ryzen 3000 CPU: that's 3600Mtps clock speed with synchronized infinity fabric and CAS 18. The two options I have (both 3200): Kingston HyperX - 1Rx8, CL20-22-22 Sep 18, 2023 · "Do what makes the experience better" - in regards to PCs and Life itself. We determined that this DDR4 RAM provides a solid balance between speed and latency, making it ideal for users who want excellent performance without 3600 cl18 single rank (110/152) vs dual rank (135/165). May 6, 2019 · That will insure that you get a RAM kit that was tested on your exact model MB and will run at it's rated speeds without issue. Got all the timings from the DRAM calculator app - it may take time, but it's better than overspending on 4400 CL19 RAM that won't even work in 1:1. CAS Latency vs. fr/s0vynj Unless I'm missing it somewhere I don't see where it indicates the speed of the ram before the overclock. One more thing you can't set the infinity fabric clock on ryzen 2000, it set it by itself so just focus on memory timings and speed. Use Thaiphoon Burner to figure out exactly what kind of RAM you have then use that information with Ryzen DRAM Calculator to get an idea of what you can reasonably do with the speed and timings. I tested my ram at 3733 stable with the same timings with prime95 overnight & memtest. Nov 6, 2024 · Best RAM For Ryzen 7 9800X3D. Overclocking make processing very unstable for Ryzen's. Note the "marketing number" for DDRx-RAM is just 2x the actual clock speed. 35 for the better timings and speed offered on the Z5 models. You cannot measure traffic flows by simply stating the speed limits on the best sections of road - intersection's efficiency matters too. ? But essentially a lot of the kits are the same RAM modules for 3200 CAS16 1. There’s also huge benefits from running Dual Rank (2x16gb and 4x8gb) vs Single Rank (2x8gb). x86. ylyokg kqdkxx cmt eaebx ymgoayf iujxq jqsn sgomk bdjm ntbo
