Looking for some knowledge on SK Hynix J-Die

[jackoneill1984]

Recently started tuning my memory kit I bought when I built my PC. I'm getting some weird results using the DRAM calculator for Ryzen. The timings work and using Prime95 large ffts and haven't had any issues. Memory stats from thaiphoon are below. Along with the current "stable" timings.

I've been trying to tune the memory at 3466 which is the maximum spec for my motherboard which is a MSI B450 Gaming Plus paired with a Ryzen 5 2600X. These timings below appear to be stable with Prime95 large FFTs and while gaming they just seem really weird to me. 

 

 

Basically I am just looking for some constructive criticism or some knowledge from people on here as I am an amateur. Hell I didn't know what XMP was a year ago.

You're CPU limited here, Zen+ ain't gonna go any higher than 3200MHz with any RAM.

 

Edit: oh, you are stable then, don't you ? What you're asking about then ? If these timings work then use them, what's so weird about them ?

[Juular]

I have Hynix CJR too by the way, and DRAM calculator shows rather off values too for me. I've just experimented by myself, lowering them one by one, i'm stable at 3800MHz 1900fClk 2T 16Cl 19RcdRd 16RcdWr 19Rp 34Ras 32Rc 497Rfc with G.SKill 3600MHz 19CL 2x8GB kit on R7 3700X and MSI B450 GP.

[Jurrunio]

Maybe just raise them to 3466MHz with XMP enabled and see what happens? DRAM calculator didn't exist before Ryzen, and people still managed to tune their memory properly

I have seen someone do 3600MHz with super loose timings or 3466MHz with actually decent timings (16-18-16-36 I think)

I read a post by Stilts (apparently he's good at this) and he mentioned that the Integrated memory controller on Zen+ can go up to 3533 on a large sample of chips. I guess I'm just wondering about the timings. They seem to be all over the place. 15 18 19 17 at 3466 seems wacky based on my knowledge level. I spose if it works it works then lol.

That's what I've done, the 3466 timings are what I've managed after doing some initial tunning on the primary timings. I haven't used the DRAM calculator for that as it doesn't have my JJR die in there anyways. I have been having a lot of fun doing it on my own working from the XMP as a baseline. Just wanted to get some insight from folks who might have more experience than myself. I'd try Reddit, but I've seen how they can treat boobs like myself.

I wish I could tune the infinity fabric but I can't justify upgrading my processor at the moment. So your gaming plus is handling those timings well? Is it the Max version or the original?.

From a bit of Chinese review, seems like JJR is a straight downgrade from CJR even though JJR is supposedly the successor of CJR. It's a bit worse on Intel (1-2 ticks worse for the same frequency and voltage) and much worse on AMD (with 1st gen, cannot go past 3400 no matter what while the same CPU can do 3533 with good CJR). Good samples of JJR can still do 3600MHz 16-19-19-39 on 3rd gen AMD though so let's say most people won't spot the difference.

 Thank you! This is something I didn't find on my own. Most things I found said it was the same as but that didn't jive with my testing. Even if it is a sample of one.

Hi guys, my English is not good.sorry (Ukraine)

HYPERX Predator DDR4 3200MHz 16GB Kit 2x8GB (HX432C16PB3K2 / 16) 1.38

Hey this tread helps a lot for me, I have Team Night Hawk RGB 3200 MHZ kit which also label at DRAM Manufacturer: Hynix; DRAM Component: H5AN8G8N??R-UHC*; in thaiphoon burner reported me. Then i read your topic here and try to with the Hynix-CJR memory timings on Dram Calculator.

Last weekend i am into memory tuning and i have manage to get my memory 3600 MHZ stable 1T Command Rate 16-18-18-19-38-56- (tRFC)548 @1.4V Dram voltage and 1.1V SOC voltage with 48ohms procODT on MSI B350 Tomahawk with Ryzen 1600AF @4.0GHz. Could Manage to post and boot into system between 1.37-139V  but giving me read or write errors. I could have slightly better timings with 3466 MHZ with even lower voltages like 1.36V. I would upload pictures after i am back home. (sorry for my language if i did any grammer mistakes, because it isnt my native language.)

Here my 3600 MHZ settings for Hynix JJR or CJR die. 1.1V SOC 1.4V Dram 4.0GHZ Ryzen 1600AF @4.0GHZ

Edited February 17, 2020 by soulclick
Forgat to mention that it has 48 ohms procODT

[soulclick]

Today i found this topic on the web which helps a lot.

I was trying set the SOC lover than 1.1V but getting errors, after i read this topic i set my SOC first 1.025V than test for errors, do 3 cinebench runs get the best score 1098, then , set SOC 1.0125V test for errors, do 3 cinebench runs and get the best 1115 score feels good. (best cinebench score @1.1V SOC was 1076). 

Edit: After some research i found that my R15 scores are pretty low. I did swap my CPU Ryzen 2400G to Ryzen 5 1600 AF old cinebench still thinks that i am on 4 cores 8 threads, lol i never try to check how many threads working on cinebench my fault sorry. After that i reinstall the R15 and make a quick test giving me score around 1384 points.
