DRAM calculator for Zen 3

[Space Lynx]

Thanks for the reply. I did everything you mentioned but no luck with gear down mode disabled, but it did improve my latency to 57.3. I guess I would have to wait for better BIOS, maybe AGESA 1.1.8.0. Do you think that CL14 is possible at 3800mhz with my kits?

new bios is making things worse for ram actually, at least for me and one other person... so lol

ATTN MSI x570 Tomahawk owners, the new BIOS 1/04/2021 just released

I have not done much yet, but I did a quick OC on ram, ran cinebench and stable so far. Lot's of testing to go :D DL link: https://download.msi.com/bos_exe/mb/7C84v153.zip Main link: https://www.msi.com/Motherboard/support/MAG-X570-TOMAHAWK-WIFI edit: so far stable, 30 more mins of...

Damm, I'm gonna try that right now, very impressive timings. I see that you are using gear down mode, I guess with 4 sticks is very hard to achieve. Is this a daily driver? Do you use any cooling fan?

@dgianstefani very impressive too, I think if I remove 2 of my sticks I would be able to achieve something like yours, but I need the extra RAM. I wasn't able to find any good 2x16GB kit.

This actually boots for me, however i had a BSOD at first, but then i went to BIOS and disabled spread spectrum, enabled SOC Uncore OC and disable C states. I have some questions for you.
1. Do you have those settings like that?
2. Since you have almost the same setup, 5950X and X570 Aorus Master, what voltage are you using for the SOC and where do you change it in Tweaker or AMD Overclocking? Whatever voltage i select on Tweaker doesn't get applied, for example I selected your voltage 1.1375V but in zen timings i get less than that.
3. Out of curiosity what kind of PBO are you using for your CPU. I currently have 280/230/230, Scalar auto, +50Mhz boost override, curve -25 all cores.

No cooling fan but have fans that send air that way You can see my most recent settings here https://www.techpowerup.com/forums/threads/aorus-x570-master.257392/page-16#post-4430185

2. SOC voltage is set to 1150, but try setting it lower if it dosent work you could try 1050
3. I am trying negative 5 curve settings on my best cores and negative 10 on the rest. I cant make it stable with higher negative values - 30 would not boot

Please add your curve experience to this thread https://www.techpowerup.com/forums/threads/amd-curve-optimizer-any-guides-experience.275640/

@jesdals your memory settings let me boot but as soon as I run Aida benchmark I get an BSOD. Could you export your bios settings and share it with me? I would like to try it.

Is this B-die Ram? im dealing with Sk Hynix die, just trying to find out if they any good settings for Hynix, i am using 4X8, board is crosshair formula VIII x570, CPU is Ryzen 3700X.

Yes, I have b die A2

Please note that there is difference between memory and cpus - so sometimes you get lucky and some times not - I have actually not that many settings - but hope it works for you

 

[juanyunis]

Didn't get lucky, but I think is because your module was rated for 4400Mhz while mine was for 4000Mhz so probably you have a better bin.

But thank you so much for your help, hopefully future bios updates would let us achieve fclk 2000 mhz with the sticks.

So apparently the best OC on zen 3 is to actually run 4 memory sticks.

This just landed at gamers nexus.

Hello All,
this is my first post

I have a 5600X on X470 Aorus Ultra Gaming
I can "run" it with last bios with some little problems (cold boot reset bios setting / SIV software does not automatic start and set a profile)
It make 4250 points in CB20 without PBO enabled
My rams are Flare X 3200C14 with XMP active
I just upgrade from 2x8Gb to 4x8 Gb after see video that show improve going to "dual rank on 4 dimm"
The score in CB20 is almost the same 4300 but the loading time in game, for example BFV, is 1/4 than before (from 20 sec for example to 5 sec)
I would like to try to run the memory to 3600Mhz o maybe 3800Mhz, what do you suggest?
Actual temp in game are not so good 40/45° because i have a 3080 on a vertical mount waiting waterblock to add in custom loop (it is stopped in Belgium since 30/11)
Thank you in advance for your help
Manu

@Trusconi I'm no expert by any means, I'm learning myself too but I can tell you that you have check what kind of chip is inside you memory, is the new second kit the same brand/speed like the first kit? In order for you to check the chip, you have to use thaiphoon burner to read info about the memories. Ideally if you have a samsung b-die then it should be possible. Try thaiphoon and upload a picture of the results.

If you're talking about CPU temps being around 40~45°C then I dont think you can get it any better unless you have some exotic cooling device.
If this is your dimm temps then its pretty high, around limits of any kind of RAM. You can temporary add a fan somehow close to RAM with airflow directly to sticks. 4 modules have little to no space between them and case air flow wont do the job, especially if you want to OC them.

All 4 dimms are the same : FlareX 3200C14

 

[juanyunis]

it is samsung B-die, have you tried using DRAM Calculator with 3600Mhz? Make sure you select the correct settings, Zen 2 (This will work for Zen 3), X570/B550, memory rank 1, 4 sticks, Samsung B-die, bin select the one with A1 or A0, and then put 3600Mhz, click on safe and try those values. If ti does post and it is stable you can go ahead and try 3800Mhz.

For safer values, you can export the XMP profile from thaiphoon burner and import it into DRAM (this will put the bin selector in manual, which is desired).

CPU temperature are GOOD, if i launch a CB20 without PBO active they are under 50°
The problem of the temperature of the RAM comes from GPU "pass through cooling" solution on new 3080 cards.
It will be solved with waterblock...if they deliver it to me.

 

[Zach_01]

How do you mesure dimm temps? As Thaiphoon reports, your modules doesnt have temp sensors. And believe me the 3080 passing through cooler is your least problem. 4 dimms next to each other can heat up rather quickly. And if you're after more speed for them it will get worst.

try to export the XMP profile and then use it in DRAM calculator, that would be the safest route.

HWinfo
This picture is after 15min in idle, it goes over 40 after 1 hour of game.
In idle i have 6 on 9 fan running 700rpmm, in game i have 9 fans run 1200rpm

As you can see on top right i have imported XML

oh you are right, but it is weird that it didn't populate the information (ns) on the left (mine did), anyway try the safe one, using recommended values. Let us know if it boots.

Is now correct?

 

[juanyunis]

Yes, that is more likely. If you take a look settings are different from your previous post. By the way you should really start with 3600Mhz, just to be on the safe side.

 

[thesmokingman]

That doesn't always work well since dram calc is running off a set/table of assumptions. For ex. my 4000/c17 16gb dimms exported gives really poor timings in dram calc. In real world I know they run much faster since I'm running them much faster. In this case it's ignore dram calc's xmp reading, not always but it happesns.
