Need help with RAM timings

[Maozi]

hello

 

i got gskill 3600Mhz 16-16-16-36, but it is unstable with Ryzen 2700x and Asus prime x470-pro

i used XMP profile, when i installed and crashed in game - got black screen

 

then i changed to 3550Mhz, 1.37v, 16-17-17-17-36 and game didn't crash, but in Prime95 it showed an error after ~1min

then i changed to 3466Mhz, 1.37v, 16-18-18-18-38 and now no error in Prime95 for ~15mins, but in open world game(BDO) i see that Frametime jumping up to 150ms, when opening map or killing mobs

 

i am thinking is it still because of unstable RAM or it is just game engine or ping lag...

 

what else i should try? 3400mhz, 1.36v, 16-17-17-37 or higher Mhz, timings and voltage

I myself use this for memory testing

 

https://hcidesign.com/memtest/

 

need multiple instances to test enough memory space, I tend to test 4GB below what I have. Use as many instances as your CPU have threads.

 

I'd try 3466 1.45V 16-16-16-16-36

How many sticks? If it is 4 sticks then it won't probably stable at those speeds, but if it is 2 sticks 2366 should be doable.

2 sticks..

do u mean for 2 sticks it is possible to run at 3600Mhz?

[Jurrunio]

and btw what is your SOC voltage? the IMC prefers around 1.1V to get the most performance, though different CPUs are slightly different in this regard.

Up your SOC voltage. Its a common fix for Ryzen memory stability. You are save to up it to 1.2v for 24/7 operations.

other voltages are on auto, because i found out, that CPU boosts higher with auto voltages... i tried to overclock it to 4.3Ghz, but failed, got max 4.25 with ~75C, but wasn't worth, because stock turbo has almost same performance

SOC 1.2v and XMP default settings?

You are good to go up to 1.2v on the SOC Voltages. I have to run mine at 1.15v to be stable.

auto voltages are dumb, I hope that goes without saying

 

SOC 1.2V is common for APUs since higher SOC voltage helps with GPU overclocking and that scales with voltage, 1.2V is a balance between memory OC and GPU OC. I'd go lower for CPUs.

ok, but i am asking, if that will fix crash with XMP 3600mhz, 1.35v, 16-16-16-36?

i tried to set manual CPU voltage to 1.35, but then it has lower boost...

Its possible. Never going to know until you try.

I dont think XFR still works with manual voltage or even adaptive, you'll need offset mode

Yes. On 2 sticks 3600mhz worked for my ram, but when i got up to 4 sticks i have to now run at 2933mhz.

Are you on 2x16gb? If so, you're gonna need to go down to 3200mhz, maybe a little lower to be stable. Dual Rank kits just don't do over 3200 on ryzen at the moment (Though that will change on zen2)

 

Try 16-16-16-36 on 3200mhz 1.35v and see if that works. I was looking all this up a while back about 2x16gb because I was buying a kit for zen2. Settled on 3466mhz cl16 samsung b die, because it was a safe option considering they were going to improve the memory on zen2. Found out over 3200 just doesn't seem to be fully stable on zen or zen+.

 

You could also try pushing the kit down to cl14 if the first attempt I've said works.

at 3600mhz and 3550Mhz i have beeps and PC makes loops until i do force shut down, when restarting PC

 

i ran https://hcidesign.com/memtest/ with 3466Mhz 16-16-16-38 1.39v and got 0 erros, 3 instances were over 110% and 1st instance was 100%, when i stopped test

 

i suppose that is best what i can make work with my hardware

Which RAM slots did you use?  If numbering the slots starting from the closest to the CPU to furthest from it then you want to use slots 2 and 4.  And yes, it absolutely matters.

 

Also update BIOS.

 

And you won't need anywhere near 1.2V and you probably won't even need 1.1V on SOC.  I'm currently running my 3600MHz at 1.0V on SOC.  

 

My 3600CL15 needed 1.37V to run DOCP, but I didn't run DOCP at length as I immediately began overclocking my RAM.

This will spawn HCI memtest windows for you:

GitHub - integralfx/MemTestHelper: C# WinForms GUI to automate HCI MemTest

 

I like TM5 with the 1usmus test profile:

This one isn't free, but it is probably the best:

RAM Test - Karhu Software

 

And the Ryzen DRAM Calculator will help:

NEW!!! DRAM Calculator for Ryzen™ 1.4.1 (overclocking DRAM on AM4) - Overclock.net - An Overclocking Community

 

And a useful tool to check your timings in Windows -- the Ryzen Timing Checker:

i think just have bad luck my hardware, i can't make my RAM stable higher than 3466, when i change to 3555 or 3600, then sometimes beeps when restarting game and in loop turns on/off...

when i change my RAM speed to 3466, then no more problem and all tests running without any error

 

probably that is MB problem, because i tried to overclock my Ryzen 7 2700x up to 4.3 and failed, max what i got was 4.25 with ~74C when did stress test and stable overclock was 4.2 with ~70C...

some ppl told that it isn't worth to run 4.2 and better to go back to turbo mode
