Twr = 2x trtp
And I think you don't need too high voltage on Vddp or iod.
Use Aida 64 to see your latency and improves. And how you know it was stable? You use tm5? Or hci?

Vddp on auto same with iod and ccd, stress tested with p95 so blend of ram and cpu, p95 failed workers @ 1900fclk with 1.1v soc but no failures after boosting soc voltage to 1.15

This be a hynix kit so it actually performs better with a bit of slack in the timings, also cant go below 380ns trfc or I have problems. These are the same timings I was using for 3600mhz so I'm a little surprised they run fine at 3800mhz with only a small bump in trfc to keep the 380ns, factory clocks are 550ns for this kit.

Also since switching to the 5600x my memory read has gone up around 10gbps from the 3600x and latency has improved by about 10ns, checked with Aida64. Tried tighter timings and the result was rapidly failing workers in p95.

Aim for 300ns and maybe 18-18-18 with a small bump in voltage

I have a Gskill Trident Royal B-Die kit with DOCP of 3600mhz CL16. I haven't had much luck with overclocking using the DRAM calculator. I have posted my 'best-to-date' stable settings, but these are based of a motherboard preset with a DRAM voltage of 1.45. Any suggested tunings would be great. I feel like I should be able to achieve a much better latency...

 

[freeagent]

Yup.. she's still good

You can probably run 3800, want to try? If not you can do the following at 3600:
Ras 28
Rc 42
Rrds 4
Rrdl 6
Faw 16
Wtrs 4
Wtrl 12
Wr 12
Rtp 6
Rfc 256
Rdrdscl 4
Wrwrscl 4
Rdwr 8
Wrrd 3

Rest as they are.

If you want to try 3800 disable gear down mode and set 2t. Set first timings as 15 15 15 15
Ras 30
Rc 45
Rfc 272
Rdwr 9

Rest as I wrote above

Thank you for the response. I wasn't able to boot with the 3800 recommendation. I have tried many different 3800 configs, but it just wont take. The 3600 settings worked, but the first pass through Aida64 was moving in a very bad direction.

Look at ramspeed. You are running 2133

Thank you for the suggestions, I have more testing to do, but initially the read and latency is slightly improved. I was not able to boot the 3800 settings although I am not too concerned as my plan when I bought the sticks was to always run at 3600mhz. I was just hoping that due to the B-Die I would be able to get down to CL14, which I have, but I just thought that there was a possibility of a lower latency. I have reattached the zen timings and the first Aida64 pass. Thanks again.

Your aida has improved latency by 1ns, but should have been around 57-58ns. Do you have a lot of bliatware? Try running aida 3 times in safety mode, see how it goes. If latency is below 60ns then you have a lot of bloat in windows. If it's still above 60ns you can try soc 1.1v, iod 1.06v, ccd 0.98v, vddp 0.94v, see if it helps.

Any secret to running GDM Disabled 1T with Dual Rank above JDEC specs? I can only run my B-die kit at 1333:2666

Depends on your board maker and CPU sample. Fill out your exact specs and post current settings.

Boot into windows with GDM disabled and 2t set, reboot and set 1t again and GDM should remain disabled.

X570 Xtreme, bios F35, cl14 3800 DR kit 1.5v, 5800X. Using Ryzen Calculator I have to use DRAM PCB revision A3/A2/B2 to get the right timings. Other than that everything is left at Auto except VSOC @ 1.025v, and VDIMM @ 1.45v for 1333/2666 GDM disabled 1T Simply increasing those two voltages and increasing 1:1 speeds isn't stable. Highest IF stable speed is 1866.

 

[freeagent]

I have not been able to pass 1900 running DR.. Best DR I can do in a stable fashion with my 5600X is 1833, so if you got 1866 stable with your 5800.. good job. My 5900X will do 1900 with DR and SR, but anything faster than that is not stable for me. 1933+ in DR will not even post for me. It is a serious slap to the pee pee that I cant do more than 1900 with SR on the 5900. My 5600 is good for 2K stable, and can bench at 2100 1:1. That CPU is kinda funny like that. Bet yours will do 2K with an SR setup.. but DR is still better, even if it is at a slightly slower speed.

My first suggestion, despite what all might say... forget about Ryzen Calculator. It works like crap. I had found out my stables on few kits just by trial and error, it doesn't work well with Ryzen 5000.

Just find a starting spot. Each frequency step actually has different procODT, rtt and clock drive strengths to pass the boot and those are the key elements to survive RAM training, RAM stability ie timings come next, you can set them very loose, there are very crucial timings, If you miss the tRDR and tWRW pairs, you also won't boot if you miss those. Gigabyte also has it own attitude also, I had GB as my previous board, I want a vocation from them. I would suggest 3200 or 3400 as start point. Voltages actually doesn't matter that much, those come later to make it PRIME stable.

Also best solution was to copycat timing tables from similar motherboard and agesa users and try them out. If some settings start to post, then tweak them till those are stable. There are many examples here and AIDA thread.

These are mine for example. I cannot boot past 3400 without GDM at all, but the penalty ain't that large. Just remember to use even numbers with GDM as any odd ones will be counted +1 to make it round.

 

[529th]

My old 3800X had a strong IF. Could do 1900.

Here's my other UEFI/Bios profile for 1833/3666. I don't like running long stability tests all day long so I settled with 1833/3666. With Intel Memory Latency checker it scores 69ns for some reason.

Changing Rtts can help and is 8ften required for 1t gdm off, 2t gdm off is easier, try that first

 

[Krit]

Crucial Ballistix 2x16GB, 3000MHz, CL15 kit

Seems to be stable at those voltages.

3800Mhz, CL16, FCLK 1900Mhz, 1.41v

SOC 1.00v
VDDG CCD 0.880v
VDDG IOD 0.960v
VDDP 0.840v

What about voltages overall this is a good result for thoose voltages ?

Overall good, but try raising ypur soc voltage a bit, see if aida improves. Iod at 1.00 and soc at 1.08v might make system faster.

 

[529th]

@Verbatim Are you WHEA error free at that IF speed? Also, have you tried Ryzen Calculator for tighter timing suggestions? My timings were using 'DRAM PCB revision' 'manual' even though it's an A2 PCB revision.

I tried lower also higher voltages and results are the same. There is no difference in Cinebench, Aida64 or MaxxMem2.

Yes with those timings and voltages there are no errors. Usually i test memory stability with dram calculator memory test and it works. Yes i tried tighter timings and it's stable but for me slightly higher speeds are not so important i'd better will use lower voltages and rock solid stability.

What other tests have you done besides Memory tests? 1900 IF I can pass memory tests but immediately WHEA with OCCT

Whatever I do, I can't seem to hit more than 3733*1.00675 = 3758

If I use 3800, I can't even post... Not even with anything in AUTO... Although I could with a 5600X I had before this
