so i ran it overnight with 20 runs. got 8 errors, i forgot to screenshot it but most were error 0, one error 5 and an error 14 that i seen. Max ram temp was 54c
going to retry at 1.47v with a fan on the ram to see if its temp related


@Taraquin so i reran the test twice, once with no fan on the ram and once with a fan on it. (attached is a photo of the run with the fan OFF).
1.47v both times.
second run got 1 error 4 and that was it so it seems heat makes it worse but doesn't solve it.

not sure why it added to the last post but yeah.

Try tRAS 40, tRC 62 and tRFC 528.
 
@Taraquin think BZ mentioned a few times that both Rev.E and Rev.B can be temp sensitive. I'm guessing it usually only shows at the higher end, and not nearly to the extremes as B-die, but still.

Though honestly nowadays I'm starting to feel as if everything should be treated with caution. Initially thought DJR wasn't, then someone said it was, and now I'm wondering if CJR is as well.

i actually got even more errors that time
 
Taraquin said:
First try clkdrvstr 40 20 30 24. If that doesn't improve things try trrds 6, tfaw 24, reset to the previous trfc, trc and tras.

updated timings 1.png


so i did the first change and it still had errors, i did then second but had to stop after 10 so i could use the pc and still had 2 errors
updated timings2.png


im beginning to think either my cpu or my ram just cant do 3800/1900
 
@Dar1usElite CJR and DJR are kinda similar but imo should not push more than 1.45V through CJR (DJR XMPs up to 1.6V but it's much newer and much stronger). I'm 90% sure that if you look at the stickers on the DIMMs, the string above the barcode should end in 8821C so CJR. DJR would be like 8820D.

On my CJR (dual rank 2x16GB 3600 17-19-19 Trident RGB) there was some benefit running up to 1.4V, but past that I couldn't get CL16 stable at 3800 no matter what VDIMM. 3733 worked fine at 1.37/1.38V or so - it was my 3700X that was shit.

But if your CPU is the problem, TM5 can sometimes pick up IF errors, but you should also be seeing WHEA Logger events for Bus/Interconnect at the same time.

Even if it's not notorious for temp sensitivity, best to get some airflow over those DIMMs. 55C+ is hot, I only managed to do that with the CJR by intentionally hotboxing it in the NCASE with intentionally bad airflow
 
3800/1900 on my 5800X with some cheap RAM
 
VSOC looks a little low, maybe try 1.125-1.15, and if SOC has LLC I use lvl3.. I don't use llc on vcore though.

It's hynix d-die according to thaiphoon burner. It's got a fan directly in front of it and temps are maxing at around 37c with 1.48v.

Im following the instructions taraquin has said to a tee. I use llc on the vcore for when I'm over clocking but it shouldn't affect the ram

Taraquin said:
Try the following: Set ram volt to 1.4V, set GDM off and enable 2T. Set tCL to 17.

I'll give that a crack.

On rare occations a higher soc and iod voltage can be needed, but generally they don't cause specific errors in TM5, more like general instability. I would be surprised if higher voltage resolves this.

If this doesn't fix it try setting first timings to 18 22 22 22 40 and all others on auto, if that resolves errors then some subs are problematic.

And leave the voltages as they are?

At this point im genuinely contemplating tossing this kit and getting a good bdie kit. It seems the cpu can do 1900 if fine but the ram won't, I haven't had a single crash or blue screen since setting the iod and soc voltages

Leave voltages etc as is :) B-die is easier to work with, but 32gb dual rank is very expensive.

Alright it's currently running the test with the 2t and gdm disabled. We'll see how that goes overnight as it's 1am here

ran the test overnight got 1 error 3

It might be tCL that is the issue then. You might be able to tighten other timings like tRC and tRFC which affect gaming a great deal more than tCL :)

It's not DJR until you check the stickers. DJR is usually reserved for >4000, Thaiphoon loves misidentifying ICs and 3600 16-19-19 / 3600 17-19-19 is one of the notorious examples (other is Samsung C as B-die). If it's 8821C, it's not DJR no matter what Thaiphoon says. It can only make an educated guess based on what it sees programmed in SPD.

Most of the time CJR falls to 17-19-19 XMP by 3733, and 18-22-22 by 4000. Might be some truth in that. Seems to a be a quirk of CJR that it can bench a lot of different configs (3800 16-19-19, 3600 16-18-18) that will still never pass stress testing no matter what.

I have most experience with B-die, rev E, Samsung C/D and Hynix A. If you get rare errors in stresstest but it's stable in gaming etc I would stick with it :)

Yeah I'll probably end up doing that, I'll see how the next few tests go.

If you only get rare errors and all else is stable try lowering tRFC. Try 496, 480, 464, 448 or 432, find lowest that boots and do a short stability test. If that works try tRCD/tRP 21 and lower tRC by 1 if that works, the try 2 lower and tRC 2 lower if 1 works, tRRDS 4 and tFAW 16 is next in line, then tRDWR 11. The rest of the timings matter very little.

Should I do that now or try the primary settings and everything on auto first?

If you only get 1 to 2 errors in TM5 usmus 25 tests then keep you you have and test one by one. Start with tRFC as it impacts gaming the most. If you are lucky with bin you might do 432. Lowering tRFC by 80 can give you 1-3% performance by itself. TRCD/tRP and tRC can be lowered all at the same time by one. Try 21, 21, 59 first, then 20, 20, 58 etc, if lucky 19, 19, 57 might work, tRRDS and tFAW must be lowered together as tFAW=tRRDS x 4. TRDWR is half tRCDRD +1 or 2 on dual rank, if you can do tRCD/tRP 20 try tRDWR 11.

It takes time, but if you are patient and for instance end up with tRFC 448, tCRD etc 20 20 58 and tRRDS/tFAW 4/16 I think that should give you atleast 5% performance.

Info on tRFC:

If you really have DJR you should be able to do 432 or 448 if binning is avg. If it's CJR which tabasco and I suspect 480 or 496 is avg.

However I had a good bin Micron rev E, it's supposed to do 560 on 3733, but it's rock solid at 522, so if you are lucky you might do better.

it says hynix d-die in thaiphoon burner so i assumed it was djr.

Yeah, but sometimes thaiphoon is inaccurate. It's usually right, but I've seen it miss a few times.
