What V-Dimm you running to get that stable? Spoiler-those same timings run 4000/2000 fclk on 5000 chips. If your chip posts. (My 5800x has whea 19s but runs fine, my 5600x has no issues running it at all but is horrible at core overclocking) might be user error.
V-Dimm is at 1.40v. Just tried switching to 3866 and 4000, but I couldn't post on either. Was able to run 5 iterations y-cruncher, karhu up to 6500%, tm5 without any errors on 3800/1900. I'd love to be able to push it up to 4000/2000, but not sure what the next steps would be (I am content at 3800, but might mess around to see if I can tighten the timings anymore).

This entire thread back to page 350 will fill you full and burst with stuff you can learn and test.
Yep, I've been jumping around it all week. It's A LOT of info and trying to piece it together has been jarring to say the least. I think the biggest thing holding me back from any breakthroughs is not wanting to mess with any of the 'power' settings too much until I fully understand them since I don't want to accidentally fry anything.

16-16-16-16-32 looks probably stable for me at 1800 (see [Official] AMD Ryzen DDR4 24/7 Memory Stability Thread) 1866 was very unstable and 1900 unbootable however.
Maybe I'll try giving flat 16 a go on another day, when i tired running tRCD on 16 my tCL was running on 15.


On another topic,

A single error 12 popped while the 3rd cycle was running, and a single Bus/Interconnect WHEA popped 2 minutes into cycle 18.

I'm thinking I should add an extra stepping of voltage to VDDG IOD, any ideas?

Current voltage settings in BIOS:
vSOC: 1.140V
CLDP VDDP: 0.9V
VDDG CCD: 0.94V
VDDG IOD: 1.02V

Edit: Increased both VDDG CCD and VDDG IOD by a tick to 0.98V and 1.06V, passed 25 cycles of default 1usmus_v3 with no errors.

tRAS is "low" for you
either too low or too high
Either tRCD+tRTP or tRCDavg*2 or tRCDavg+tBURST
When you say tRCD, you mean tRCDRD ? How do you find the tRCDavg and tBURST?

Also on both sets tRFC is too low
It get's postponed
Either you run it as 215, with tWR 10 , tRTP 5 (soo tRAS then 16+5 = 21)
Or you run 258 , with either tRP 6 or 8, soo tWR 12 or 16
We agree that we're speaking about tRTP 6 or 8 and not tRP?

Thank you.

My apologies if this has already been discussed here, but can you, or anyone else in the know, confirm that the tRCDWR is actually being used by the Zen2/3 memory controller?
Anybody got an idea?

Small win, got a full refund for my Strix F Gaming because its not in stock any more with retailer. £270 back. Got a B550 Unify X coming today I spent £160 on.

Net win, getting a board that should be better for overclocking for much less than the retail RRP of the Strix last year.

Are your memory temps fine? I started getting random TM5 errors and whea 19 warnings on a previously stable setup when ambient temperature increased and the dimms under stress started exceeding 60°C

Also I almost finished TestMem5 automation script to collect per-cycle screenshots with information if there were any errors. It's possible to even get all the errors in format "cycle: list of errors", but that requires further work, and might not be needed.
Just teasing 😎
A screenshot tool that barely uses RAM would be really helpful for it.
It's beyond me why TM5 never get's updated to log better before a BSOD or reboot corrupts the log.txt ~ but that's the dev's problem
TestMem5 automation script v1.0.0 is released 😇

After 2 days trying to lower my tRP to 17 and failing (i've worked around with all secondaries and terciaries, my pc just frooze), i've followed @Veii suggestions and i give 16-20-20-40-60 a try, it passed, and then i tried 15-20-20-40-60.
I've forgot to screenshot the TM5 results but here is my new stable 24/7 settings.

Shooting in the blind here, the non RBG sticks of Crucial Ballistix does not have temp sensors.

Hi,

after months of testing.
still not 100% clear sound, popups, crackling noises etc. issues since b450 board with r3 1200 and 2700x and now with the 5600x
tried different soc voltages, ccd / iod / vddp / vddg and so one

ch7 bios not liking both manuell vddg voltages.

suggestions for timing and voltages that can help or how are the chances to get rid of sound popups with another board ?
thanks in advance

@Asutz I'm not sure if it will help you, but I have it set like this.

No WHEA, no sound/USB issues.

Took a gamble but this mobo looks totally unused
thats exactly how i got my B550 gaming edge wifi board...which said
USED-GOOD but when it came in the only thing opened was the box, the
board package, wifi antennas, pamplet etc all were unopened.
(same thing with my old 1660 super evga version (un-opened package but the box
was opened) everything else still there (B4 the great PC scurge) is the US dollar that
much different than that in EUROs atm??? 180 euros vs 250/300 usd is quite the difference....
(EDIT) was higher this morning when i looked...
(another edit) found the NON X version for around the price you mentioned in US currency
but still its the unify not the unify X

HOLY **** i guess the US dollar is worthless rightnow....

@Veii Finally some progress, after 2 days trying (and failing), i managed to get 4 cycles stable, looks like my board was not 100% stable at 1866FCLK (actually it were, but i had to give a large bump on SOC and VDDG_IOD voltages, it probably made tRP17 impossible), so i lowered to 1833, loosened secondaries and tweaked SOC and VDDG voltages and now it passes until 4 cycles (still testing).

Can confirm this morning it was my Strix F Gaming that must have "blown up". B550 Unify X turning on fine with my current power supply. Just need to build everything again fill my loop and its time to test.

I love the cute "test bench" legs MSI give you with the motherboard 🤣

Also that clear CMOS button on the back of the mobo 😍 Having to take the side off a Lian Li O11 XL any time it was necessary to clear the CMOS on a Strix was awful.

Hello guys I´ve tried to read up on the last 50 pages but I still have a couple questions for my 24/7 timings.

View attachment 2518253

It´s stable on tm5 and Karhu but I´m still unsure about:

1. my tCCD_L is 7. Should i adjust tFAW then or am I gonna be fine?

2. I have no idea what to do with tWRRD. Should i just keep it at 4 or is 3 or 1 better in terms of stability?

3. Same goes for tRTP. Should i increase it to 9 or is 8 fine?
Your setup should be able to do 3800, if you have tried and failed, just try to ease up on tRCDRD, go from 16 to 18, and i am sure you will succeed.

I have the same memory as you, but 4 sticks, and i was running 3800 at 16-16-16-16 for a long time, but being unstable. Then i saw one of the seniors here saying (it could have been Mannix or Craxton, cant remember) that easing up on tRCDRD is one of the easiest ways out of being stuck on getting forward with timings or instability.

Now im running 16-8-18-16 and it is perfectly stable!
