Ryzen DRAM Calculator by 1usmus

TheLostSwede: Also TRRDS and TFAW should be chaned, they affect performance quite a bit. Lowering them from 5 and 20 to 4 and 16 improved avg fps in SOTTR bench with 3 fps and min with 4 fps. Running on autobthey often end up around 7-8 and 30-35 which deteriorated performance even more. Command rate and TRAS/TRC should be lowered as well since the latter two to my knowledge is tied with tRFC and keeping them at auto often makes it impossible to lower tRFC as much as wanted

I guess you didn't look at my screenshots that I linked to?
My auto settings for your additions are already quite low and my command rate is already 1. TRAS and TRC are part of the standard memory timings, which I did set manually, as per my comment.

I saw your post trrds and tfaw is in a 1:4 relationship. When your trrds is 4 and tfaw is 23 the last one basically sets what performance you get. From testing on my setup a trrds of 5 and tfaw of 20 will improve performance compared to 4 and 23. 4:16 is ideal. My point was that the trrds/tfaw has a major impact on performance and is often overlooked, if you want good performance that setting should not be set to auto Just changing from 5/20 to 4/16 gave me 3-4fps in SOTTR.

Guess i am disappointed that Corsair would use both and not label them so buyers can choose.

No.

Pretty disappointing that Corsair would not label them so buyers are aware before they purchase.

v1.7.1 has been uploaded. Maybe @1usmus will do so later. I already tested the new fast settings for 3200MT and it works better than the previous version performance wise while having the same good stability. So, I came here to say thanks a lot to our member for all his hard work to provide us with good settings for our Ryzen CPUs.

For those who have no idea WTF to do now that the "Read XMP" button has gone away, and zero documentation has been provided on how to replace it:

1. Run Thaiphoon Burner
2. Click "Read" button on toolbar and select your memory
3. Click "Report" button on toolbar
4. Scroll down to end of report and click "Show delays in nanoseconds"
5. File -> Export to... -> Complete HTML Report -> select file
6. Run Ryzen DRAM Calculator -> click "Import XMP" button
7. Select the file you created in step (5)

I assume this has been done so that you can export the Thaiphoon settings, copy them to another PC, and run the DRAM Calculator there while you tweak the BIOS on the actual Ryzen PC - but honestly @1usmus, you really need to include these basic operating instructions with your software.

PCB revision set to Manual:
Timings are displayed correctly

Set PCB rev to A2 and get timings:
Still correctly calculated but reading from XMP import gets zeroed

Switch back to manual and get timings:
Primary timings are set to 0

1.7.1 works very well so far Got a bit better scores on membench than previous best with 1.7.0.

Just got bumped to 1.7.2: https://www.techpowerup.com/forums/threads/dram-calculator-for-ryzen-v1-7-2-released.266904/

Gained a bit of performance with the new Safe settings vs the old Fast settings for A0 DJR. A tiny bit lower on bandwidth, but dropped a whole 0.5ns without changing CAS or RCDRD. Didn't change any of the other subtimings except tRFC, tRAS and tRP loosened up compared to the old recommendation. A bit better in membench too.

68.4ns AIDA, 68ns custom and 69ns random in membench. AIDA latency matches my old unstable 16-18-18 experiment, except this is 16-19-21. I like this new update quite a bit.

 

[Chomiq]

Currently I'm running 3600 cl16 that's tested to be stable, got the timings by a mix of trial and error plus input from oc.co.uk forum thread for ballistix lt overclocking. Always had to input all timings manually as auto proved to be a mess on my board.
I'll give 3733 another go during the weekend. Honestly right now all I care about is stability and verifying that is the most time consuming process.
Anyone can check if the timing issue I observed was fixed in 1.7.2?

Edit.
It wasn't fixed.

 

[HD64G]

Already used the 1.7.2 after I saw it uploaded. Very nice update since by using it I found out (through trial and error) that my chips are 1-sided Hynix revision A2, so I have put into the UEFI the values suggested by this great tool for the safe 3466MH/s. Seems stable for now after same basic stability testing but I will report back later if anything changes.

In the Advanced Tab, the "overclocking potential Dram" section is now blank, marked as n/a, what is up with that?

May I report a bug that on the 1.7.2 version of the tool causes an application error that prompts me into closing the application and even if I press continue it doesn't show all the values?

Update: Importing report from Thaiphoon burner worked to allow the tool to make a suggested profile but the profiles don't work at all. It doesn't even boot for 3333MT/s and 3466MT/s. The safe preset profiles are working well though.

The Fast profile doesn't always work, it seems to mainly work with Samsung B-dies and this is why the Safe profile is the one to start with. I'm sure you can tinker a bit and end up somewhere nicely in the middle though.

Me thinks that the tool gives some results not close to reality (check my screenshot below in the chip quality section)

Spoiler: 3333MT/s manual suggested settings page 2

Well, it's A tool, nothing more, nothing less. I don't expect perfection, regardless of how good the author of the tool is.
It clearly has helped a lot of people getting a good starting point with their RAM, but it's not a success for everyone.
There are also a lot of variables to take into account. I dunno how the Patriot's Hynix based modules work with the 2000-series Ryzen CPUs, but they've performed well over expectations for me.
That said, the Overclocking potential does look a bit insane.

1.7.3 appears to have fixed the fatal error that previously occurred when using an HTML from Thaiphoon. But the recommendation stays the same, 3600 CL14 on DJR, I'm not sure if that counts as a "safe" profile......it's also the only profile available under Manual PCB.



As @HD64G also mentioned, in 1.7.0 the Overclocking Potential box listed 3733/16 as an estimated limit for my kit. In 1.7.2 and 1.7.3 that's become 4222/16. Since this feature hasn't been present in any of the changelogs since it was introduced in 1.6.x, I'm just going to assume that its recommendations aren't valid anymore.

That box has been marked N/A in the last two versions for me.
Only the first version I downloaded showed values there.

It's not blank if you import xmp profile from file, at least for me. It goes blank once you change pcb rev to anything other than manual.

Yeah, not working now.
First version showed figures that made sense, now it shows some ridiculous negative figure about 6 digits long.

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.

I think I've got the same value for my kit so it might be hard coded to E-die.

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.
