Alright Thanks for your profile. Tomorrow I'll check it myself and give some suggestions about it but for now what you can try is this:

Set you memory to XMP profile and stock settings (1600 from XMP profile for memory). unlock Infinity fabric clock and set it to 1900 and try to boot. If it doesn't want to boot then you know your processor doesn't like it. 3733 is the only option then. If it boots then you know it's your memory giving you a hard time.

For memory use V1 profile Safe preset. use ALL values. power down disabled thought and definitely gear down enabled.

If it boots with V1 safe move on to FAST. if it still doesn't want to boot on SAFE then raise tRCDRD to 18 and try again with the same SAFE V1 profile. see if that helped.

Other options is to raise procODT in with the safe preset to 36.9 or one step higher that might also solve the issue to boot. Use the Safe preset as a starting point and step by step loosen things and see if it results in something. If not, set it back preferably unless you saw any kind of improvement.

Gegi Hello!

I'm using the Corsair Dominator Platinium RGB (CMT32GX4M4C3600C18) 4x8gb on my asus x570-e mainboard with the ryzen 7 3800x. I used the fast preset of the dram calculator for 3600mhz and it works fine... but my latency isn't that good compared to the other people here... Is there a way to improve it? Or is it that bad because I'm using 4 sticks?

Thank you in advance

Yes you can try safe settings first. V1 and I meant it's too low and you should raise it 1. Also you can't use unequal numbers like 17 with Gear Down disabled. So keep that on. Like I said, your Bdie is low bin. It's not the same quality as most bdie out here so you might run into some issues but they can be smoothened out. You should still be able to reach 3800 with some minor tweaks.



I don't have you XMP export file from Thaiphoon so I can't generate the right numbers for you. If you would post that file here I could help you out a bit more. I have higher binned Bdie myself, I know which values the bdie will complain about once you start pushing it. This should be similar with the lower binned bdie. I can give you suggestions which values to loosen.



And might I ask which motherboard you are using?

Cidious somewhere I read about memory jitter and I didn't think so much of it. But I felt my system was lagging here and there mostly on opening things. And this was using the standard DRAM calculator settings with only 2 tweaks of lower voltage and ClkDrvStren to 40 instead of 24. Then I started tinkering with some more tertiary timings changing them 1 by 1 and suddenly my lagging in windows was gone.

The timing that I think was responsible for removing the jitter was tRTP. I changed it from 12 to 10 and now when I boot up windows it's buttery smooth and responsive. But I also changed some other timings that might have an influence together: tWR 16 -> 14, tRDWR 9 -> 8, tRFC 580 -> 560.

I'll push a little further with the settings. So far it's error free and made my system buttery smooth. The attachments contain 2 screenshots with the slightly tuned differences. Latency went down only slightly and read bandwidth went up 700MB/s(ish).


Micron E-die for if you have missed my previoust post.

Maybe it's not clear, so I will repeat the questions:
- i did what u have suggested. IFC at 1900 and memory near stock (like 1700). Now you are mentioning something about XMP. So should I change everything to XMP profile (3200mhz 15-15-15)? And for which reason? I thought we are testing the 3800 setup.
- Then about the V2. The calculator doesn't even work at Fast for V2. So, should I select the Safe, I guess. But with which settings? 3800 or something else?
- regarding all Vsoc, Vddp, Vddg, dram voltage everything is as you are mentioning
- About tRCDRD. First you say it is too high. Then later you say to raise it. What it got to be?

If you want to solve your issues you need to be willing to try some of the suggestions. Youre clearly stuck and I have a clue why but I cant help you if youre not willing to try as I suggest. Manual is not a viable profile in this case.



And I said use memory on stock speeds like XMP profile so you are sure that it will boot and THEN set infinity fabric to 1900. Youre trying all things at the same time which wont work.



I hope you can please try as I suggest and Im sure we can figure out whats holding you back mate.



Try V2 first. You have Bdie but you dont have good bdie. Im sure it can boot with better settings but you need to do it step by step.



Use V1 profile as I said and if that doesnt boot raise tRCDRD. VSOC 1.050-1.1 (I ran 1.050 without issues) VDDP 0.900 VDDG 0.950 DRAM Voltage 1.44 should be more than enough to start at.



Report back after that. and remember to use ALL settings of the calculator profile 1. if that doesnt post then We can try a few other steps.

Checked the V1 profile and it's with more strict figures, so no reason to try them.

Enable gear down (opposed to the preset settings where it says disabled. This doesn't work well at all even with higher CtlrDrv). and then it should stick but it's depending on your processors memory controller some Ryzen 3000s don't like 1900 IF clock. You can test this by unsyncing your memory with infinity fabric clock and setting infinity fabric to 1900 and memory to stock speeds. if it boots you'll know the processor can handle the infinity fabric.

gerardfraser 3800 Mhz CL16-16-11-16-36-52 1T @ 1.36v SOC 1.05 62ns Can run 3800Mhz CL14 but takes more DRAM voltage.
