I am running two sets of B-Die right now, both from G.Skill. I am reading about all the problems you guys have faced.. just wanted to thank you for beta testing.. I am on year two with my Ryzen system and it has been smooth sailing from the start heheh. Thanks for not making this a frustration box. Side note, I am running a set of Royals and a set of Black and Whites. The Royals outclass the B+Ws in pretty much every way. Both are 3200C14, and the stickers are about a month apart. They rip with my 5600X.

I just got the Ripjaws. I hope to play with them tonight and see what they can do.

Instantly booted up at 3600 CL16 as I expected. I'm going to find the ceiling for my IF then figure out which CAS I can run at.

DDR4-3600 @ 14-14-14 is nice. :thup: I have the 2x16GB Trident Neo DDR4-3600 16-19-19 kit (not B-die) & would like to see if they can be tightened or if I can push them toward 3800, or a little of both. I'm also waiting to see what the 5800x3d will look like.

You can set tRFC at 260-320. Anyway, from this point, nothing will really make the difference. Try the same timings at 3733 or 3800 1:1. Maybe even 4000. It should work at higher voltages. Good luck with the higher clock. My Ryzens 5000 were all pretty average or below average and I couldn't set more than ~3733-3800 1:1.

The CL16-19-19 kit is almost for sure Hynix so depending on the IC you can set 3800-4000 1:1 ( C-die won't go much higher) or up to 4600 1:2 (if it's A/D die). 4600+ at CL18 or even CL20 1:2 is pretty fast too. For Ryzen 5000 APU it's a great option as you can set 4600 1:1 and results are better than on Samsung B. For non-APU I guess that 3733/3800 1:1 at tighter timings will be still the best.
CL for Hynix is scaling well with the voltage so once you bump VDIMM then it will make something like 3800 CL14-19-19 or 14-20-20. Sub-timings can be significantly tightened too and it doesn't require higher voltages. Sub-timings can actually give you more than main timings.

Instantly crashed trying to do anything higher than 3600 with CL14. I think my CPU is limited to 3600 :(

More like it needs a higher voltage. Samsung is scaling with voltages up to 1.9V+. It's not recommended to run so high daily but there are memory kits with XMP at 1.60-1.65V so I assume this is still safe for longer when the RAM is not overheating. 3800 CL14 kits have 1.55V XMP profiles. New 4000/4266 CL16-19-19 dual-rank kits have 1.55V too.
