Ryzen DRAM Calculator by 1usmus

[Chomiq]

This is Hynix CJR, so I think that theory just went out the window.
But it would be funny if the memory IC makers hard code a value like that into their ICs.

What I meant is that it might be hard coded in calculator. Last I checked it showed 4166 CL16 in that section for my cheapo kit, would have to double check the % value.
It reads the xmp from html5, recognizes that it's Hynix CJR or Micron E-die or any other type and based on that it throws the "chip quality" value.

 

[Decryptor009]

I have Samsung B-die.

REALLY shit RAM, not even a drop of 1 in latency is stable, any frequency increase and the PC won't boot lol.

 

[Assimilator]

Remote connected to my PC at home today to do something unrelated and figured I'd have a look see what shows up, for science or something...

Apparently my RAM has a 105% chip quality and can apparently go a lot higher than I'm running it at, if that's to be believed.

Yeah, the overclocking potential figures are total nonsense:

    if (MT.SelectedIndex == 0) // samsung b-die
    {
        double num = 8.174;
        qual.Text = ((int)(num / tCLns * 100.0)).ToString();
        qualsafe.Text = ((int)(num / tCLns * 4400.0)).ToString();
        CAS.Text = "CL16";
    }
    else if (MT.SelectedIndex == 4) // hynix mfr
    {
        double num2 = 9.76;
        qual.Text = ((int)(num2 / tCLns * 100.0)).ToString();
        qualsafe.Text = ((int)(num2 / tCLns * 3533.0)).ToString();
        CAS.Text = "CL16";
    }
    else if (MT.SelectedIndex == 5) // hynix afr
    {
        double num3 = 9.76;
        qual.Text = ((int)(num3 / tCLns * 100.0)).ToString();
        qualsafe.Text = ((int)(num3 / tCLns * 3533.0)).ToString();
        CAS.Text = "CL16";
    }
    else if (MT.SelectedIndex == 6) // hynix cjr / djr
    {
        double num4 = 10.0;
        qual.Text = ((int)(num4 / tCLns * 100.0)).ToString();
        qualsafe.Text = ((int)(num4 / tCLns * 3933.0)).ToString();
        CAS.Text = "CL16";
    }
    else if (MT.SelectedIndex == 9) // micron e/h-die
    {
        double num5 = 10.0;
        qual.Text = ((int)(num5 / tCLns * 100.0)).ToString();
        qualsafe.Text = ((int)(num5 / tCLns * 4133.0)).ToString();
        CAS.Text = "CL16";
    }
    else
    {
        qual.Text = "N/A";
        qualsafe.Text = "N/A";
        CAS.Text = "N/A";
    }

The calculation completely ignores what your kit is rated for in terms of MHz and only looks at its (raw) CL. Also, all kits will do CL16!

IMO that area should just be deleted from the calculator.

 

[HD64G]

A clear bug indeed. Previous bersions could have worked well but not sure as I haven't tested most of them.

Quite impressed it does CL14, but it doesn't appear to be fully stable. Hard freezes/black screens like once a day. Any suggestions on first steps to improve stability?

 

[HD64G]

If you went for the max settings (red rectangle values) just loose some main timings after the first one.

 

[Firedrops]

Thanks. I was on the orange recommended settings, will try incrementally pushing up to Red values. Just wondering, should I increment all of them together, or one at a time (e.g. if it's still unstable at RAM Voltage 1.39, then start increasing SOC Voltage from 1.025... and so on?)?

I recommend you follow the written guide from the author of the tool you're using:

AMD Ryzen Memory Tweaking & Overclocking Guide

Memory overclocking has a significant impact on performance of AMD Ryzen-powered machines, but the alleged complexity of memory tweaking on this platform, largely fueled by misinformation and lack of documentation, has kept some enthusiasts away from it. We want to change this.

www.techpowerup.com

Try auto all settings for any setting in the tool. It shows you how important procODT is when u can go from 11 errors to zero with 1 setting. It was 53.8Ohms for me before I set 40Ohms. Then its a case of tuning following the guide from the most important to the least. I have some settings on auto that I when I was just using DRAM calculator were set. I have not gone past 3600Mhz. I have done in the past I but when I do I'll follow the guide starting with proODT. I'm running 4 x patriot viper steel 4400C19.

To get basic stability try all the red values together and if all works well you can try reducing SOC voltage firstly step by step.

 

[Space Lynx]

hey guys, is this ram supported by Ryzen Calculator? it is SK Hynix (my hope is to get it to 3600 cas 16-18-18, its stock is 3200 cas 16-18-18) first I plan to try just changing the 3200 to 3600 and the voltage to 1.41v and change nothing else, and see what happens. then go from there. what do you guys think?

If this is verified by Thaiphoon to be either CJR (C-die) or DJR (D-die), then chances are you won't be doing 16-18-18 at 3600. These ICs just can't scale on tRCD and tRP like that, even with voltage, because that's a Samsung thing. I could easily boot, play light games and bench AIDA and CB at 16-18-18, but as soon as memory sensitive apps and games started up it was BSODs and errors galore, and it ended up irreversibly corrupting my Windows installation.

I'm not ruling out the possibility of 16-18-18 especially with crazy voltage, but it's highly unlikely and also highly unnecessary for performance.

The current Fast preset in the calculator (CJR/DJR are lumped together) works okay on performance and general stability, if you don't want to spend too much time.

I can't tell the quality of your specific kit on hand, but refrain from giving it voltage unless you've verified that it actually needs it for stability, especially before youve done enough testing to get a feel for your kit. Sometimes, specific settings are essentially to achieving stability and no amount of voltage will overcome them if they don't get their way, eg. my B450 ITX easily handled my 16-19-19 but my B550 mATX needs GDM enabled to be stable at any 3600 profile.

 

[FilipM]

The Calc needs to be updated with Samsung C-Die settings, if possible.

Long story short: I got a new Ryzen build last month and immediately got into RAM tuning. I was miss guided by Thaiphoon burner thinking i got Hynix CJR (Considering Kingstons history with SK Hynix) - Turns out I got Samsung C-Die

- Negative scaling with voltage, sweet spot usually at 1.32 to 1.35
- Can't run primary timings as tight as B-Die
- Can run as good or better secondary/tertiary timings
- Clocks high but again, loose primary timings
- TRFC limit is around 310ns (TRFC Value in bios = Latency (ns) * Ram speed (MT/s) / 2000)
- Cannot run tRDRD SCL below 4
- Cannot run tWRWR SCL below 4
- Doesn't like GDM OFF

I am running:

- 1.33V DRam
- 1.05625V SOC
- VDDG (Both) at 1.0
- VDDP at 0.95
- procODT 34.3
- RTT_NOM OFF
- RTT_WR OFF
- RTT_PART RZQ/5
- CAD_BUS @ 24-20-24-24

Here is what I have achieved so far with CL18 and 3600MHz with this C-Die kit.

* Note: 2204 bios added ~1ns latency to my runs vs 1407 on my X570 board. Need to test with latest bios

* Note2: I have a preset stable at 3533/CL16-19-19-38 @1.4V. Scores worse than the preset in the pictures.


I hope this great tool will be updated with C-Die settings as they seem to be hitting the market even in other manufacturers (Corsair/GSkill)

 

[Megatron]

In reply to "what do you guys think"? I've got a little experience with RAM overclocks with M2Z3600c18 Corsair Vengence Pro RGB 2 x8GB and 4 x8GB Patriot Viper Steel 4400. Everything was a mystery while I blindly followed the recommendations of the calculator. When I needed to really get something stable I used the guide on this website about memory overclocking for Ryzen written by the programmer of the DRAM calculator. He said set XMP, set your frequency, now tune proODT. I wiped all my errors away when I changed this single setting to 40Ohms instead of 53Ohms. My Patriot unlike the Cosair is not sold as "Ryzen compatible". My motherboard Gigabyte X570 Aorus Elite on F12f had no idea about my RAM obviously illustrated by the poor choice of proODT by default. There is an F20 bios but I've not tried that one yet (possibly it could have better tuning for my RAM).

I have not gone above 3600MT/s after following the guide, I will at some point. However my settings @ 3600MT/s blow the Corsair @3800MT/s performance out of the water in the DRAM calculator built in memory benchmark.

 

[ragp13]

Should I expect to use different DRAM settings for B550 boards when using DRAM Calculator, or can I just use those suggest for B450 or X570?

 

[TheLostSwede]

Should I expect to use different DRAM settings for B550 boards when using DRAM Calculator, or can I just use those suggest for B450 or X570?

Unknown. I would try the X570 settings, as the platforms are more similar than B450. That said, it does depend quite a bit on what's inside the UEFI as well.

 

[phnz0]

In the next week I'll tell you about the plans that will be in the next versions

I have a probably dumb question, but here goes. Do you have to run this on the AMD CPU PC you plan to overclock the RAM for? I have downloaded it to my current Intel PC to try to run and pre-generate my timings for the build I am currently constructing and the app crashes my system.

I am building out the following:
Ryzen 3900x CPU
MSI X570 Unify
G.Skill F4-3600C16D-32GVKC (2 x 16 GB)

 

[HD64G]

This tool works only on Ryzen systems if I remember correctly.

 

[phnz0]

Good. I was hoping that was the case. Will run it once I am up and running the new system.

 

[Assimilator]

I have a probably dumb question, but here goes. Do you have to run this on the AMD CPU PC you plan to overclock the RAM for?

No.

If you refer to the post I wrote on this https://www.techpowerup.com/forums/threads/ryzen-dram-calculator-by-1usmus.246327/post-4261865 you need to do steps 1 through 5 (Thaiphoon Burner) on your Ryzen PC, to get the SPD settings. But steps 6 and 7 (Ryzen DRAM Calculator) can be done on any PC/laptop/tablet - the calculator only requires the imported file.

I run the DRAM Calculator on my laptop which sits next to me while I'm tweaking the BIOS of my Ryzen PC with the calculator's values.

(I can no longer edit that post or I would add this info into it.)

 

[s2nascimento]

Good afternoon, I ask who can be available of course. I understand informatics reasonably well, but I don't know anything about overclocking, I always thought it was burrise and destroyed the pieces quickly "something that doesn't really understand". Now I got interested and I'm watching a lot of videos and forums, but I wanted help from you because my case is a little complicated. I wanted to reach 3600MHZ with 3200MHZ modules.

Motherboard - B450 Aorus Pro
Processor - Ryzen 5 3600
4 modules of 8GB HyperX Fury - 3200MHZ (with 2 modules having JEDEC 3200MHZ and 2 modules having JEDEC 2400MHZ) 1 pair of memories is from [Kingston C-Die] and the other pair is from [Micron E-Die] which further complicates my situation.
Source - Corsair 600W Reais.

I wanted a direction on how to set my overclok settings if possible, because I tried the DRAM Cauculator standard numbering and it gave many errors in the memory test and windows gave blue screen a few times and because of that at the moment I am only with the XPM standard 3200 even.

Hi,


Does anyone have Patriot Viper Blackout 2x8GB 3600C17 kit paired with zen+ cpu? Coz im having serious problem setting them up correctly on my B450 Tomahawk Max (latest bios). My sticks, are running stable 3466C18 @everything on auto





Ive been able to boot and do some testing at 3600 but theyre unstable






sadly none of these settings from dramcalc are working



After long time playing with everything i decided to ask for advice on tpu forums cuz im close to giving up on this kit.
Would appreciate some help especially if some1 got same kit.

Your problem isn't the RAM likely the IMC on your 2700, Ryzen + AKA 2000 series only guarantee 2933mhz RAM even though you can use XMP/DOCP and calculator to reach higher speeds, 3400 seems to be about the max stable for most chips on Ryzen+, mine is the same 1600AF which is for all intents and purposes is a Ryzen 2600, I'm 100% stable at 3400 even with cas 14, though 3600 isn't quite stable no matter if I loosen timings or increase voltage, you might be better shooting for tighter timings at 3400 than being focused on reaching 3600, you can see anyway apart from rezad, your write and copy speeds are faster at your 3400 settings

I have 2600X+, same Zen+ IMC as you have, but got my system benching & daily gaming at 3466 with safe recommendations from Calc v1.7.3. This is with dual ranked 32GB kit too. Use to be on B450 but now X570. A limitation of your memory OC could very well be the topology of the board your on. No way to tell for sure unless you can obtain X570 setup & test with it.



Now testing @ 3533 atm.

On another note. I'm not sure how many in this thread do pre windows testing before actually booting into your OS with recommended calc settings. Personally I always have used Memtest86 to do this, & at least as a minimum 2 passes. Can take 6+ hrs just to do that with 32Gb kit.
