CMK32GX4M2B3000C15 attempt to 3200Mhz partial work

Hi guys,

dot worry abour RC, that has nothing to do with stability, if u put it too low, it will slow down your RAM, if u put it too hig, it will also slow down your RAM
RC is time from RAS to CAS, which is same as 20+40 (in your case), feel free to use auto in there, it will work
as for main timings, they are usualy fine left on spreadsheet values (but ryzen doesnt like CL 15 that much, so stick with 16)
they dont impact stability that much, and since u did put voltage this high, they will work even at lower values (not CL tho :P)
but for now try to work with cl16

RRDS is usualy 6 (at 3200)
RRDL is usually 8 (at 3200) i use 9 for 3333+ othdrwise i get cold boot issues
those two if too high or too low (even if by only 1) will produce too many ram errors or inability to post

then i would worry more about tFAV and tCKE those two have way more stability issue than u would think of

i may have different ram than yours (samsung b die dual side) but in my case at 3200 tfav at anything different than 37 is unstable, as your main timings are different than mine, u will need to figure out your own working number

as for tcke, keep it auto for now

can u run passmark memtest from usb stick?
see there on which test ull get errors and how many
if u get hundreds of errors than start with tfav going +1 or -1 see in which cae ull get more or less errors
if u manage to go from hundreds of errors to only few
then go with tcke +1 or -1

mate those timings at 3200 will produce far worse ram performance than cl16 at 2933
choices going forward are either

buy some samsung b dies
or
sit down ,take some time and work out exactly what timings to enter and try for EITHER
3000 mhz with lowered primary timings with your corsair
or 3200 with sensible timings

but 1.45 volts and cl20 isnt where you want to be at all

if you want send me a link to the screen shot of thiaphoon burner (the first step in the ram calculator and i'll work it out for you)

any way you look at it cl20 isnt what you want

have you actually tried the ryzen ram calculator ?

ive been using it since the first revision its now on version 11 or something
and yes it works on corsair as well as samsungs and the flash stuff

add to that grab some example settings from the stilts ram thread and see what you can get from them sticks of ram

oh, forgot to mention, previously just run calculator, Hynix MFR V2 gave the closest parameters to my existing ram, but upon immediate entry of below reference output, immediate F9 beep failure. At first just give up altogether, then later sat down as you said, try one by one change.
