Please post your stable CJR timings first.

I wanted to start a thread for everyone to share their timings, tips and tricks with the newer Hynix CJR ram.

If you know anything about it, you'll know that info is scarce online about these chips and they are capable of some really great speed.

I have the G.Skill Ripjaws V 3600 19-20-20 F4-3600C19S-16GVRB chips and I'm currently trying to get it to boot past 3200!

Doing memtest as we speak at 3400 currently at 16-17-17-38-56 1.37v.


On my Ryzen 1700x the 3600 xfr is a no go for me sadly.

So if you have CJR, post up your timings and settings that you're stable at and hopefully we can all get through this together.



Here's my memory dump:

Found this on another thread that may help:
"In my experience, the Ryzen DRAM Calculator should be used as a learning program (at least for now since there's no CJR support), and yeah CJR is pretty new and there not much information about it now.


So, what I learned OC'ing this RAM is that you should increase the timings each 200MHz-400Mhz overclock (If it's cl15-15-15-15 at 3000, you should increase it to cl16-16-16-16 at 3200, and so on) and tRAS by +2 or +3 (if it's 35 at 3000, it should be 37-38 at 3200). The procODT is very sensitive aswell, I can run at 60 Ohms at stock speed, but if I increase to 3200 I should decrease the procODT to 53 or even 48 Ohm. RttNom should be 34 Ohm or less (preferably off if OC'ing more than 400MHz), RttWr should always be off, RttPark works best (at least with me) at 48 Ohms or lower. The CAD BUS Driver Strengths should always be 20 Ohms (maybe 24 Ohms if you're not doing any agressive overclock).



tFAW really helps aswell, it should be DRAM Speed/100, (so, 3000MHz would be 30 tFAW) maybe increase or deacrease a little bit for better stability. My chip really loves low voltage, it's semi-stable at 3466MHz with 1.37v. And finally this chip really loves 2T aswell, and it doesn't seem to have any significant difference in performance compared to 1T (the difference is up to 2% in performance impact with sinthetic benchmarks, so basically 0% performance impact on real-world applications) so if you can't get it stable at 1T (even with geardown), stick to 2T be cause you'll probably be more than fine with it.

Note: procODT is REALLY sensitive with voltages, high procODT and High Voltages crashed, low procODT and low voltages doesn't work, medium procODT and medium voltages work with a little bit of tweaking."

Anyone here using 64GB RAM with Zen 2?

https://www.gskill.com/specification/165/169/1536043466/F4-3600C19D-32GSXKB-Specification

Got 4 sticks of these. Dual-rank 4 DIMMs is a ***** to overclock!

Same RAM 32 gig worth , on my 3700x Aorus Elite rig x570

No problem running at 3600 XMP, but thats with stock 20 CAS timing

Xmp certified timings are 19-20-20-40-60 (Ryzen rounds up CAS to even numbers)

Trying to figure out the simplest way of getting that CAS down lower without losing my current 100% stability

Tried the Ryzen Dram Calc settings once , and got blue screens. Didn't go much further with it.

Has anyone tweaked these bargain 3600's down to better timings.?

Thanks for the info m8. I am also having problems with my setup (R5 1600x + C6H) and Hynix CJR (2x8Gb Ripjaws V F4 C15 3000). Tryed playing with Dram Calc but not much success. I can't seem to get more than 3000Mhz @CL14. Tryed almost everything, but it's too early to say - got it from RMA this morning (as a supstitute for my old Ripjaws which had Samsung E-dies). 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 3466 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... I guess it is like you said, CJR is fairly new on market and Ryzen 1000 is more than 3 years old... Anyway, i'll try to play with it again tommorow, if unsuccessfull i think i'll simply swap with my friend... 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, 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 says a completely different values...

I am getting amazing overclocks on a sk hynix cl 18 series. rated cl18 3200 but does cl 16 3600. I am shocked it s 32gb module Patriot cheapest 3200 32gb per dimm.

Hello 1s1mple,
I just realized that you successfully managed the exact mainboard and RAM I am currently fiddling with to get stable and error free (I am more or less a novice ).
Would you be so kind to share this working mainboard user profile with me to help?
Kind regards,
mhhd

I'm pretty happy with my CJR overclock. I have a 2600x that won't go above 3466 on the ram frequency, but using Dram Calculator in conjunction with some Memory Overclocking guides and what other users have posted online I was able to get 3466 running at Cas 14. Look at the UserBenchmark results at the bottom. Nearly 36,000 benchmarks by others with the same ram. The average user score is 89% and I managed 131%. There are only a couple of blips on the chart higher than mine. Probably users with 3000 or 5000 chips that could reach 3600 or higher. DRAM Voltage 1.45. SOC Voltage 1.0625

How can i share my user profile?
The ram settings that are working with overclock are showed in the screenshot.

Hi,
under 'tool' in the main top row, there is a section 'Asus user profile' where you can store and load different profiles. There you can load and save to USB as well (and so subsequently share your profile if you want). Meanwhile I got my system running with the help of your read outs, with some adjustments on the voltage side as here the read-outs do not exactly correspond to the settings. So no real urgent need for me any longer
Thanks for posting all your details anyway as it helped me greatly with getting my system working.
Kind regards,
mhhd

Came across a discussion. I will share my overclocking results. I do not attach a memory stability test, I am too lazy to spend time on this, I can assure you that my sticks can easily take 4000 and even 4200 MHz. The essence of my post is that I achieved the maximum overclocking of the Infinity fabric for my cpu and adjusted the memory according to its frequency as tight as possible. Although I think it is possible to squeeze the tRFC timing a little more.

I would love some tips on tuning my CJR's for an intel build to make warzone run a bit snappier on my guest build for when friends come over!
2x16gb C16 3600mhz dual rank memory
8700k 5ghz 0avx
gigabyte z390m gaming (T-topology board)

Should I am for 3800 with similar timings? or push for 4000+ cl18? Anyone have some quick and dirty settings for intel to start? I hear CJR gets quite hot past 1.40-42 ish is that correct? Any tips or suggestions regarding command rate?
Ram Serial for reference

Thanks guys!

I read through this whole thread and didn't find a definitive answer... When you're using 4 sticks of RAM. I have 2 kits of G.Skill 2x8GB DDR4-3600 16-19-19-39 from 6 months apart... Anyway, I was trying to get the thing to run faster than XMP for a long time, with little success. When I pair them I was going with the original kit in A2-B2 and the new kit in A1-B1, and I was pulling my hair out, because 2 sticks will go to 4000 at 1.4V without any major issues. 4 sticks would take 2 out of 3 memory checks to POST at XMP. Now that I have paired them with one pair in A1-A2 and the other in B1-B2, they can do 3800 at 1.37V. And it will POST at 3800 with the memory just slightly loosened from XMP, just bumping TRP and RAS. I felt that worth mentioning because they don't really even spell it out in the motherboard manual. Ideally you want 4 identical sticks. But, 2 batches just 6 months apart and they don't match quite the same. The idea that the IMC for the Ryzen treats this as 2 sticks of dual-rank made me try the slot switch. I was getting errors the first runs through at 3800, so I dropped it down to 3733 and went through a 30 minute run of OCCT without that lady voice yelling at me how much I screwed up. Before the swap, it was even a sometimes thing to get it to POST XMP after messing with the settings. Now it POSTs more cleanly/quickly after exiting BIOS. Thought it may be a helpful suggestion to others that have struggled with 4 sticks. A and B are the banks. When using 4 sticks, it pairs A1-A2 as a single dual rank logical memory unit, and B1-B2 as another, if my thinking is correct. Otherwise, it is just a fluke and ignore the whole mess.
