New ram not the same type, how to use DRAM Calculator for Ryzen ? (2024)

New 2x16gb corsair vengeance ram 3000mhz cl 15 both set run 3200mhz cl 14 but not together. Msi x470 gaming pro

I think my old ram is Hynix AFR ram and the new ram (still corsair vengeance 3000mhz cl 15) is samsung ram (wtf)

How do i oc, i can't use DRAM Calculator for Ryzen 1.73

Can you share your full timing configuration? I think termination timings are incorrect for using 4 DIMMs at the same time.

Since Samsung B-die easier to overclock it should work with AFR preset of Ryzen DRAM calculator.

Timings are just stock atm

I am not interested in the stock configuration.

Please share the settings you are changing within the bios when just running 2x8GB at 3200MHz CL14.

can't remember but was something like this (i have several pictures of the settings)

Screenshots contains a very high procODT for a Ryzen 3000. Value like 40Ω should be enough.

Please try to apply the following values to see if the system even wants to boot at 3200 CL16 with 4 DIMMs installed.
If it boots, then we can tweak tCL, tRCDWR, tRCDRD, tRP, tRAS and tRC values

why cl 16, 1 pair (2) ram stick can boot at 3200mhz cl 14

It wouldn't boote, gear down mode i couldn't adjust, it was grey and on aut, soc voltage i could do 1.125 or as i remember 1.000,not 1.025, i keept it at aut

If you set Command Rate on 1, it will lock GearDown Mode in the bios. Just keep Command Rate on Auto then GearDown Mode can be enabled.

Try the same settings again with the following modifications
tRFC = Auto
Memory freq = 2133
FCLK = Auto

When the system boots, please download ZenTimings and share the screenshot of the output.

I think i have ver 4.32 and the new ram is 5.32, i know some corsair vengeance 3200mhz ram are rated as amd optimized ram, might be why my new ram is samsung ram, i don't want to go crazy, 3200mhz would be fine, my old hynix ram can do 3660 cl 16 on a asus prime x470 pro mbhttps://valid.x86.fr/ki4zmg (yes im using a different cpu im having a litte fun with until theres a bios update for my msi x470 gaming pro mb, so fare it's stable at 4.5 ghz, at that speed the 4500 mhz is red in my bios, but im fine with 4.5ghz with so fare 1.250 volt only stability tested at 1.260 volt)

Thank you for the screenshot.

Lets try to change the following settings:
Memory freq = 3200
procODT = 48
tRDRD SCL = 5
tWRWR SCL = 5
tRDWR = 8
tWRRD = 4

booting

UPDATE crashing doing ibt normal, it actually last time rebooted

Does it happen after a few minutes or longer time of stress testing?
Is your CPU at this moment overclocked? If yes, please undo the CPU overclock so the memory stability can be properly tested.

Please try the following changes:
tWTRL = 14
tFAW = 36

less than the rounds of ibt normal (less than 2 min)

cpu is oced, it's normal stable (ibt with ram at stock setting, prime 95 small fft, cinebench R15 and R20)

ibt normal passed

ibt passed oced (less oc)

I would say, stress it with OCCT for like a hour just to be sure.
Can you share a current screenshot of ZenTimings?

I lowered it, 1.250 volt isn't good enough for 4.5ghz, mabye i didn't had to change tWTRL = 14 tFAW = 36 since my oc wasn't stable in ibt normal, with ram at stock settings it was stable at 4.5ghz and 1.250 volt

You could try to set the following:

tCL = 14
tRCDWR = 17
TRCDRD = 17
TRP = 17
tRAS = 34
tRC = 54
tRFC = 480

couldn't get it to boote

You can't get odd numbers without turning off power down disable and it's mate in the list, can't recall it's name, gear down disabled I think.

Ryzen calc hasn't been setup for non linear memory kit's, it expects you to have bought a quad stick kit not as hoced two dual Pack's as I and some do, you can't expect the settings to pan out, try auto more.
