4000 Mhz Ram For Ryzen 5000
Ryzen 5000 RAM Guide: Observe The All-time RAM For Your Zen 3 CPU
When it comes to processors, even the best can exist made better through a little tuning, and that statement certainly holds true with AMD's market place-leading Ryzen 5000 processors. These chips often don't overclock to bleeding-edge cadre frequencies, instead relying on automated algorithms to excerpt the best cadre performance. Nevertheless, tuning your memory tin significantly improve performance. In fact, often just selecting the right kit with the correct number of DIMMs tin provide tangible operation gains with a minimum of fuss. This article covers the best RAM settings and combinations for Ryzen 5000 processors, including overclocked configurations, along with a few tips on what you should expect from your chip.
Information technology's not always easy to stay on the right path, and AMD, like whatsoever other company, has had its ups and downs. Later on being off track for a few years, the chipmaker ultimately constitute the winning formula with its Zen microarchitecture. Four years after, AMD's human foot is still on the pedal and taking the fight to Intel, with its latest army of Ryzen 5000 (codename Vermeer) processors leading the accuse.
Ryzen 5000 wields AMD'south latest Zen 3 cores that introduced of import IPC gains, amongst other microarchitectural improvements. On the memory front, Ryzen 5000 chips inherited the aforementioned I/O die and dual-aqueduct memory controller as their predecessors, therefore, the mechanics remain unchanged. That's an important consideration when selecting and tuning Ryzen's retention.
The Infinity Fabric Clock (FCLK) continues to be in a permanent relationship with the unified memory controller clock (UCLK) and memory clock (MEMCLK) in a i:1:1 ratio. As usual, the trio needs to exist on the same page for optimal operation, while breaking that synchronicity results in a heavy latency penalty that'due south detrimental to performance in some applications.
DDR4-3200 is nonetheless the officially supported memory frequency on Ryzen 5000. Looking dorsum, Ryzen 3000's FCLK typically hits a wall at i,800 MHz, which means you can run the memory at DDR4-3600 and remain in ane:1:1 style. In that location have been rare exceptions where some actually extraordinary Ryzen 3000 samples could run stably with a i,900 MHz FCLK (DDR4-3800).
Nevertheless, Ryzen 5000'due south FCLK is a lot more forgiving, paving the fashion for a 2,000 MHz FCLK (DDR4-4000). AMD doesn't guarantee that every single Ryzen 5000 processor volition achieve the feat, just the majority volition. Allow's see how that impacts performance.
Ryzen 5000 Exam System and Setup
We evaluated nine unlike retentiveness frequencies in total, spanning from JEDEC's baseline of DDR4-2133 all the way up to DDR4-4000. We configured the retention manually by inputting the different parameters. Our tests included 4 different retention configurations, with 16GB (2x8GB), 32GB (4x8GB), 32GB (2x16GB), and 64GB (4x16GB) setups to assess the impact of memory ranks and capacity on AMD's Ryzen 5000 processors.
During the entirety of our tests, we kept the Ryzen 9 5900X's FCLK in sync with the memory frequency that we tested. As with well-nigh Ryzen 5000 processors, the FCLK ceiling for our sample was 2,000 MHz (DDR4-4000). To ensure consistency amid the tests, we ran our RAM benchmarks iii times and used the median value as the final result.
| Test Organisation | |
|---|---|
| Processor | AMD Ryzen 9 5900X |
| Motherboard | Gigabyte B550 Aorus Main |
| Memory | One thousand.Skill Ripjaws V DDR4-4000 C15 2x8GB; Trident Z Neo DDR4-3600 C14 2x8GB, 2x16GB |
| Storage | Crucial MX500 500GB, 2TB |
| CPU Cooler | Corsair Hydro H115i Pro |
| Graphics Card | MSI GeForce RTX 2080 Ti Gaming 10 Trio |
| Power Supply | Seasonic Platinum SS-1200XP3 1200W |
| Instance | Thermaltake Core P8 |
| Operating System | Windows ten Professional 64-chip with October 2020 Update |
| Display Driver | Nvidia GeForce Game Ready 461.40 WHQL |
We updated the firmware for our Gigabyte B550 Aorus Chief to the latest publicly-available revision. On the software front, we used a fresh 64-scrap installation of Windows 10 Professional person with all available updates. Furthermore, we updated our exam system's drivers, benchmarking programs, and game clients to the latest versions at the time of testing.
To Gear Or Not To Geardown?
Geardown Mode (GDM) is enabled on AMD motherboards whenever the memory runs to a higher place the DDR4-2666 standard. If your memory kit has an odd CAS Latency (CL) value, Geardown Style basically rounds it upwards to the nearest even number and sets the control rate (CR) to 1T.
Our G.Skill Ripjaws V DDR4-4000 C15 2x8GB (F4-4000C15D-16GVK) retentiveness kit has primary timings of 15-16-16-36. When the pick is enabled, Geardown Mode configures the timings to xvi-xvi-16-36 timings at 1T. Disabling the selection restores the timings to default at 2T.
To explore the dissimilar variables in play, nosotros tested a third configuration with the memory kit running at the default timings, but at 1T.
Geardown Style came back with mixed results in our testing. Overall, the pick had little impact on operation, with the divergence amounting to less than a 1% delta. Yet, average results don't tell the whole story. We discovered certain scenarios where enabling or disabling Geardown Mode yielded a small operation gain.
For case, in the Microsoft Function benchmark, disabling Geardown Mode boosted functioning by up to two.7%. Manually tweaking the retentiveness increased the margin to iii.five%. We saw the opposite happen in Premiere and Photoshop, where Geardown mode increased performance past up to 2.iv% and ane.four%, respectively.
We can conclude that there is no simple answer to whether you should enable or disable Geardown Mode. At the end of the day, your choice actually depends on the type of workloads y'all put your Zen iii processor through. Since we can't exam every single scenario, y'all'll have to practice some exploring yourself.
Don't await every memory kit to run at 1T, either. The high-functioning memory kits are more probable to practice 1T at the advertised frequency and timings. Some may require more transmission tuning time than others, of course.
Memory Scaling
DDR4-3200 should unquestionably be the starting bespeak for Ryzen 5000. We recorded a 5.eight% operation difference between DDR4-2133 and DDR4-3200, the native frequency supported on Zen 3. Our test results confirmed that DDR4-3600 is still the sweet spot for this generation, though. Information technology delivered seven.ii% more performance than DDR4-2133. Compared to DDR4-3200, however, DDR4-3600 was only 1.3% faster.
Unsurprisingly, DDR4-4000 is the ultimate goal if your processor and budget allow for it. The performance gap between DDR4-2133 and DDR4-4000 stretched every bit high equally 7.7%. Compared to DDR4-3200 and DDR4-3600, DDR4-4000 provided minor uplifts in the range of one.8% and 0.5%, respectively.
In a gaming surroundings, DDR4-4000 and DDR4-3600 offered iv.2% and 5.half dozen% better frame rates, respectively, than DDR4-2133. Every bit always, memory frequency only impacts specific titles where the processor does all the heavy lifting and the game engine responds well to improved memory functioning. For example, DDR4-4000 netted upward to 6.1% better frame rates than DDR4-2133 in Shadow of the Tomb Raider and up to 19.7% in Far Weep New Dawn.
Unmarried-Rank vs. Dual-Rank
On average, dual-rank memory offered up to 7% more functioning than single-rank retentivity in our application tests. In gaming, nonetheless, it fabricated almost nada difference. Naturally, not every workload volition answer positively from more than memory ranks or higher capacity — only retentiveness-sensitive workloads will probable do good from the aforementioned attributes.
The 2x16GB setup presented 20.4% and vi.seven% performance gains over the 2x8GB setup in Photoshop and Premiere, respectively. Nosotros saw like comeback in performance in y-cruncher and 7-Zip'south pinch benchmark where the 2x16GB memory kit outperformed the 2x8GB retentivity kit by xv.6% and 25.two%, respectively.
Four retention ranks are definitely the way to go for Ryzen 5000. On an AM4 motherboard with iv DDR4 memory slots, you can opt for a memory kit that'south comprised of two dual-rank or 4 unmarried-rank retention modules. The cumulative results showed a negligible difference between the two setups.
Our Cardinal Takeaways
- For the majority of users, leaving Geardown Fashion alone is the virtually sensible option. If you want that last chip of operation, you'll have to experiment with the pick to encounter whether there is whatever gain for disabling information technology since Geardown Mode'due south influence on performance is workload-dependent.
- From a functioning standpoint, DDR4-3200 is the baseline for Ryzen 5000, while DDR4-3600 remains the sugariness spot. Plainly, DDR4-4000 is the cream of the crop for operation purists. Do bear in listen that not every Ryzen 5000 processor can operate with a 2,000 MHz FCLK, but AMD'due south continued commitment to improving its AGESA lawmaking helps brand information technology a reality for the majority.
- When it comes to memory timings, tighter values are always meliorate. While we tested at CL15 to ensure an apples-to-apples comparing, the all-time DDR4-3200 and DDR4-3600 memory kits on the market place come with CL14. At the fourth dimension of writing, the fastest DDR4-4000 memory kit is rated for CL15.
- Retentivity ranks oftentimes don't contribute to better gaming functioning on Ryzen 5000, but retentiveness frequency does in an surroundings where your graphics card isn't the bottleneck and the title taxes the processor heavily.
- Even on Zen 3, four memory ranks are still the ideal configuration for getting the all-time overall functioning out of your Ryzen 5000 processor, particularly in applications. With today'south capacity, this basically translates to having at least 32GB of memory in your system, whether information technology be ii dual-rank or four single-rank memory modules. Most of the time, the showtime option is always easier on the pocket.
