AMD Ryzen Compatible Memory List

in bios is called as follow:
TwrwrScL (write to write - same bank group) - 2
TwrwrSc  (write to write - different bank group) - 1
TwrwrSd  (write to write - different rank) - 5
TwrwrDd  (write to write - different dimm) - 5
TrdrdScL (read to read - same bank group) - 1
TrdrdSc (read to read - different bank group) - 1
TrdrdSd (read to read - different rank) - 3
TrdrdDd (read to read - different dimm) - 3

Ok so I went with the timings you sugested above, and set 3333MHz with 16-15-15-15-38 and 1.4V

hmm looking at your pictures, some of your timing has either too high value or too low
coz its impossible (with valid timings) to have lower read speeds than write
as for cache...u have 4core cpu, i have 6 core cpu, and this test is multithreaded
theres not much u can do with that tbh, only overclock will help :P

and dunno if u know, but if u have single ranked ram, then u cant expect to have same transfers
coz dual rank is faster (mine :P)
but on the other hand, single ranked are easier to overclock which usualy has same effect

btw got stable 3400 :-) timings are rather loose atm, still waiting for some random errors (if any)

well i still have some backup pictures on some old settings, i think it may help you:

twrwrscl - 2
trdrdscl - 7 (default)



twrwrscl - 2
trdrdscl - 2

Have to add. Dual rank is faster than single...........Check
