Hi guys! I'm gonna copy/paste my text from another thread because i think it's dead... Here goes:
I am having problems with my setup (R5 1600x + C6H) and Hynix CJR (2x8Gb Ripjaws V F4 C15 3000). Tryed playing with Dram Calc but no success. I can't seem to get it to work at more than 3000Mhz @CL15 (not fully stable). Tryed almost everything, but it's a bit too early to say - got it from RMA yesterday morning (as a supstitute for my old Ripjaws which had Samsung E-dies - they ran
@3200MHz CL16 + tight subs). If i didn't know better i would say my IMC is crap but the funny thing is, my friend's Micron E-die (Ballistix Sport LT 3000 CL15) works great on my cpu. I had it running on 3466Mhz CL16 @ 1.38v with good sub-timings fully stable... So, i guess CJR is simply not very compatible with first gen Ryzen or it really requires some heavy tweaking... Anyway, i'll try to play with it again throughout these couple of days, if unsuccessfull i think i'll simply swap with my friend, he has R5 3600 + MSI B450 Tomahawk Max (CJR should work just fine on this)... Any chance a newer Bios could help? I'm asking because i'm on an older version of Bios (6401 with Agesa 1.0.0.6) because it should be best for first gen Ryzen...
Edit: I managed to get 3200 CL16 with a Bios update (7704 + Agesa Combo 1.0.0.4), all ODT settings on auto, timings are manual.
It's interesting to see that Auto setting prefers ProcODT @60 and RttNom/RttWr Disabled - where Dram Calc points to completely different values, guess it needs more tuning with CJR/DJR...
This is where i am at right now, i won't give up so easily but would apriciate any help/input. Thank you
