Our resident AMD Ryzen memory tuning guru Yuri "1usmus" Bubliy released DRAM Calculator for Ryzen version 1.6.0.1, which comes loaded with support for 3rd generation Ryzen processors based on the "Zen 2" architecture, motherboards based on AMD X570 chipset, and an exhaustive list of new features, and bug-fixes. AMD made major changes to the memory controllers of its Ryzen "Matisse" processors over past generations, including changing the various clock-domains and their interdependence, broader support for overclock across various memory vendors, and more, with the intention of improving memory overclocking. These also mean additional settings to be made in the UEFI BIOS setup programs. DRAM Calculator for Ryzen v1.6.0.1 greatly simplifies that, to help you simply key in the values it calculates based the system configuration it detects or you specify.
DRAM Calculator for Ryzen v1.6.0 also introduces presets for AMD X399 platform and Threadripper processors, helping out the HEDT crowd. Among the key changes are VDDG and FCLK for Zen 2, Vref (CHA / CHB) recommendations; PMU training recommendations that greatly stabilize the overclock; updated presets for Samsung b-die, Hynix CJR and Micron e-die memory modules; support for "Zen 2" processors on older-generations of motherboards (AMD 300-series and 400-series chipsets); improved tWRRD prediction for Dual Rank memory setups; an in-app shortcut to Internet overclocking statistics generation Zen 2; two new settings for MEMBench, the internal stability benchmark; and the overall stability of the program. Grab it from the link below.

The change-log follows.
- Added full support for Zen 2 and X570 motherboards.
- Added recommendations for VDDG and FCLK for Zen 2.
- Added recommendations for Vref (CHA / CHB).
- The maximum frequency for 1:1 mode is now 3800 MHz, and for 2:1 mode - 4200.
- Updated presets for Samsung b-die, Hynix CJR and Micron e-die.
- Added backward compatibility of Zen 2 with previous generations of motherboards.
- Added PMU Training recommendations for all Ryzen platforms. Better training - a more stable system.
- Added autosave of the main tab settings when closing the program and automatically loading them when the program is started.
- Improved tWRRD prediction for Dual Rank.
- Color notification of voltage limits and FCLK. Black is the norm, red is the limit.
- Timing detection for Zen and Zen+ generations. For the generation Zen 2 at the moment there is no possibility to add a definition of timings due to NDA. Unfortunately.
- Fixed a lack of presets for X399.
- Fixed a rare error in which it was impossible to calculate the timings.
- Added a button to access the Internet overclocking statistics generation Zen 2.
- For users of Intel systems in the "Additional Calculators" section, it is possible to calculate tREFI and RTL IO-L.
- Added 2 new latency tests for MEMbench.
o Custom latency is a memory access test that the processor cannot predict (using a specific offset).
o Random latency - the average time is measured for random memory accesses in a buffer of a certain size. Partially affects the result of TLB. - Both tests are release candidates, but I do not deny that there will be calibrations.
- Custom latency and Random latency are included in the Easy and Default packages. Please note that during testing, the program will open / close the prompt itself (you do not need to deal with it).
- Added information about the processor's L3 cache size. Also, the size of the test blocks for latency tests is controlled relative to it.
- Added button Clear standby. It is used to clean cached memory by the operating system. Didn't the test run? - Click Clear standby.
- Max RAM button better determines the amount of free memory available for testing. Useful for checking memory for errors.
- There are exceptions for many functions.
- Fault tolerance of the program increased.
- Graphics updated

Aaaaaand... it works !
(or seems to work, still have to run tests)
I applied the settings exactly as recommended for the calculator for my configuration, and I'm in Windows.
No plans to use the "Fast" preset, since the voltage required is a bit too much...
But the "Safe" one is still (theoretically) faster than XMP "stock"
The lowest I've seen was ~73 when using CL14 with insane voltage... but not willing to torture the memory like that since I need this computer for work, not for breaking records.
Anyway... good job @1usmus !!:clap:
I bet it will be bugged now :)
This released sooner than I thought it would. Thank you
TurmaniaI bet it will be bugged now :)
Please keep your trolling to yourself or present actual proof of such bugs.
I still cant do CL14 on my generic Samsung B-die and I refused to get it to run more than 1.35V, but its nice to see membench integrated inside :) Don't know if this good or not for 3133MHz CL15 on first gen Ryzen

What memory kit do you have?
Edit: Nevermind, I wasn't in forum mode so I couldn't see it.

He was just being funny, no worries.

Damn, ~50% overclock on "stock" voltages and better timings, that is a great result! I chickened out and bought a 2x16GB kit 3200C18 which runs at 3600C16 right now, still tweaking. :) Micron E-die though, so it was "only" 175€.

Ah. I guess I simply got triggered :ohwell:

B die is binned to death.
There is b die that can hardly do 3000mhz cl16...
The early kits sold before the hype were good, now I just buy hynix cjr, e die or any of the new ones as b die is not worth it.
Also on Ryzen 3000 it doesn't matter that much, but the calculator for safe is really great free boost.

I spend whole day tweaking this RAM, with GearDown disabled and each and every subtimings is manually tweaked.

I guess that was right. Most of the timings and subtimings are off on my B-die thus I ftweak it on my own. My goal is maintaining CL15 and goes as high as possible, 3133MHz is the maximum clock it can sustain, going 3200MHz needs to increase the timing a notch to CL16, that can go over 3400MHz but with 1st gen Ryzen don't have such good memory controller I went with 3133MHz CL15. This is my AIDA64 benchmarks, the read and write is close to theoretical (95-96%) of 3133MHz bandwidth, only the copy speed is a bit down at around 88%. Latency doesn't look too bad either.
I just wanted to give a special thanks to 1usmus, this tool and also the web article has been very informative and helpful to me in trying to get the best performance out of the memory kits I own with Ryzen processors. Tried the new version to see what it would say going from 3200 to 3600 with my memory kit but it says my configuration is not supported. I was able to successfully overclock my kit Corsair CMW32GX4M2C3200C16 (ver 4.32) anyway with Ryzen 3800x (recent upgrade from Ryzen 2600). I don't know if my kit is just weird or perhaps not identified properly in SPD where it says it's B-die but is only compatible with settings more like ones generated for "Samsung OEM" for speeds 3200 and below.
In my case the window picks the wrong size, forcing me to maximize to then be able to resize, not a big problem, but curious none the less.
Settings for my Micron B-die work like a charm at 3333MHz. As always, 3400 is impossible. Meh, good enough for cheap 2400MHz sticks.
Are these results any good?
3600mhz CL 14 15 14 28 1T at 1.45v
Hello community.
i have two different Drams.
1-Crucial Ballistix Elite 8GB 3000MHz - Samsung E-Die
2-Crucial Ballistix Sport 8GB 3000MHz - Micron E-Die
and i got these timings for each one.From (Ryzen DRAM Calculator 1.6.2)
my question is which timing should i set into BIOS to get best result?
------------------------------------------------------------------
these are my current timing which i have setted up (i did choose bigger number in each column) and its Stable so far
Can i set Lower timings ?

how do i test my latency of ram in ryzen? Lisa Su shows a graph of infinity fabric 1:1 and the sweet spot was 3600 1:1 for like 70 millisecond latency, how do i find out what my millisecond latency is?
edit: nevermind I think I found it... it says CPU latency though, so I am not sure???

No, that's correct. That column is named "CPU" instead of "latency" for reasons unknown to me.
For a sample, my own system. More or less close to those 70 ns latency, since I didn't really fine-tune it much. I just went for the best XMP settings available by default.

Nice. Thanks for the confirmation. Just glad to see I am truly running 1:1 at 3800 stable. Can't believe it really, memtest was stable overnight no errors, prime95 for 7 hours also stable no errors or stopped workers, and Witcher 3 I left on overnight just for the heck of it and no crashes.
Looks like my upgrade path is clear then, sell the 3600 when 4800x launches next year, then retire for a good 5+ years.
