Dimm train error asus - Исправление ошибок и поиск оптимальных решений проблем

Ответ Asrock (с переводом):

Что касается вашей проблемы, мы хотели бы предоставить некоторые предложения для вас, чтобы проверить.

Используйте ластик, чтобы очистить золотой палец памяти и убедиться, что гнездо ОЗУ чистое и без пыли.
Очистите CMOS, обратившись к странице руководства пользователя. 26.
Руководство пользователя: https://download.asrock.com/Ma… Legend.pdf
Для проверки установите только CPU, блок питания, кулер, RAM, графическую карту и загрузитесь в BIOS.
Установите по одной карте памяти в каждый слот по очереди, чтобы повторить предложение 3, чтобы проверить, связана ли проблема со спецификой памяти или слота.
Если возможно, используйте другой процессор и оперативную память, которые продаются двумя палками для перекрестного тестирования.

Ответ Kingston:

1. Пожалуйста пришлите фотографии модулей памяти.
Какой процессор у вас установлен?
Какая сборка Windows? Так как вероятно, что именно сборка windows ограничивает объем оперативной памяти.
2. Попробуйте обновить BIOS до версии 3.40

I have a problem with my computer, I can’t connect it. The problem happened overnight. The error that appears is «memory pmu training error at socket 0 channel 0 dimm 1»

Looking at this error in forums, I saw that it could be a malfunction of the rams memories, that they were not being detected, since this, I bought two new combs, but nothing has changed, continues with the same error.

I already tried to use all the motherboard slots, combination 1-3, 2-4 and also just a memory in slots 1,2,3 and 4, but nothing solved. The behaviors that I noticed are.

Memories sequence 1-3 2-4 The computer starts, my video card turns off its fans, the auorus logo appears with the error «memory pmu training» On the motherboard the led that is on ram initially, changes to cpu and goes back to ram again. The machine starts up again, now with an error message «memory pmu training» and «preparing for automatic repair»

It does this same process 4x, the fourth time the fans of the video card do not stop running and the LEDs on the motherboard fluctuate rapidly from CPU to RAM and the computer does not display.

Using only a memory slot 1,2,3,4 The fans of the video card do not stop running and the LEDs on the motherboard fluctuate rapidly from CPU to RAM and the computer does not display.

Some important notes

Removing the processor I could see some dark regions, small black regions, it looks like some black pins.

I cleaned the motherboard with clean contact and memories, it didn’t solve

I did reset bios cmos, also did not solve

The parts have a little more than 1 year of use

I used new memories to test

Gigabyte B450 Auros M

Ram memory was using 2x8gb 3200mhz asgard, I tested 2x 8gb corsair rgb pro 3000mhz new

Asus TUF gtx1660 super 6gb triple fan

I am grateful to anyone who can collaborate to help me solve the problem.

Question ASRock B450M Steel Legend PMU Training Error/DIMMs B1 & B2 not working?

TM1172

Commendable

So this may wind up being a sad story of self-imposed stupidity but I’m hoping there’s a fix.

Last night, I tried upgrading from a 2600X to the current 3600X. I didn’t update the bios, b/c on ASRock’s website, it said that for the 3600X, bios 2.1 should be compatible and I was already running 2.7 (not sure how but hey).

Initially, the computer just boot looped for minutes. No splash, no bios screen, just power on — 30 seconds — power off — repeat. In a moment of stupid, I thought maybe the cpu was having trouble with RAM, so I pulled the second pair out (with power off), now operating only with 16GB in slots A2 and B2 per the manual.

I replaced the 2600X into the socket, the computer booted just fine, so I downloaded bios 2.9 from ASRock and flashed the bios, figuring it was probably a bios compatibility thing. I also popped the CMOS battery for a minute.

After flashing the bios, I put the 3600X back in the slot, held my breath, and powered on. It booted! But, it gave me a message,

«PMU Training Error at Socket 0 Channel 0 DIMM 0 & DIMM 1»

Going into the bios, only the memory sticks in slots A1 and A2 are now being recognized. The memory in slots B1 and B2 are not recognized in the bios — reads empty. So with 16 gb installed in slots A2 and B2, only 8 gb was recognized by bios. With memory installed in all four slots, only the 16gb in A1 and A2 show up.

I’ve taken the following steps to troubleshoot:

-Reseat all memory
-Try memory sticks in different slots (to rule out bad RAM)
-Reseat CPU, loosen cooler
-Clean memory contacts and blow out DIMMs
-Boost DRAM voltage to 1.35v
-Boost SoC voltage to 1.04v
-Reset CMOS by removing battery

In CPU-Z, all 32gb are recognized and each channel shows timing info. Also, each stick is definitely getting power, because the sticks are RGB and they’re lighting up just fine.

The potentially tragic part: When I pulled 2 of the 4 sticks of RAM, I think I partially unseated the stick that was in slot B2, so it was half in-half out when the machine was boot looping. Being an idiot, I just pushed it back in until it clicked. I don’t think it hurt the RAM itself, since that stick later worked in one of the A slots, but I’m worried that it might have torched the mobo memory controller.

I tried putting the 2600X back in to see if all four memory channels would be recognized (thereby indicating bad CPU memory controller) but it just boot looped due to the updated bios.

So, the question — is this a problem caused by A. Bad MoBo memory controller, B. Bad CPU memory controller, C. bios update, or D. Something else?

Would pulling the motherboard out and re-seating everything from scratch be advisable? Am I totally hosed/need a new component? I don’t want to be stuck with 16gb in single channel config.

Memory PMU Training error at Socket 0 Channel 0 DIMM 0

Hi ich habe hier ein Gigabyte GA-AB350N-Gaming WIFI auf dem ein Ryzen 5 1600 läuft diesen wollte ich durch einen R5 3600 ersetzen.

Nun mein Problem die CPU (3600) habe ich Gebraucht gekauft ein Pin war leicht verbogen was ich aber wieder richten konnte. Also CPU noch gereinigt und ab aufs Board. Leider werden mit der CPU nur 1x 8GB von 2 Riegeln erkannt.
Im BIOS wie Windows 10 sehe ich also immer nur 8GB wären CPU-Z beide Riegel erkennt. Ein Einstellen der Frequenz durch XMP der RAM ist auch nicht möglich.

Des weiteren nun wie Folgt weiter vor gegangen:

R5 3600 auf dem B350 Board nach EC FW Update Tool (B19.0517.1 or later version) und aktuellsten FW (50a) wie auch Vorgänger FW (42d). Ohne Erfolg 8GB bleiben bestehen!
R5 3600 runter vom Board und meinen Ryzen 3700X drauf gesetzt. RAM werden mit 16GB erkannt und lassen sich ohne Probleme mit XMP auf 3000MHz umschalten. Also mit der CPU das BIOS wieder hoch auf 50a und geht immer noch .
R5 3600 auf mein X570 Board und ins BIOS hier meckert er nicht rum und meine 4x8GB (32GB) werden ohne zu meckern angezeigt.
R5 3600 wieder aufs B350er Board und 2x8GB aus meinem X570 System mit rüber genommen um zu testen leider wird auch hier nur 1x8GB erkannt
Mit einem Ryzen 5 1600 und Ryzen 7 3700X werden die RAM korrekt erkannt mit 2x 8GB RAM.

Gigabyte Support ist angeschrieben die lassen sich aber min. 3 Tage Feiern bis ich mit einer Antwort rechnen kann.

Meine Vermutung ist das die CPU durch den Verbogenen PIN Teildefekt geworden ist?

So sah CPU nach Erhalt mit DHL aus . Wärmeleitpaste Reste habe ich auch schon mit Brennspiritus und Pinsel entfernt doch defekt bleibt bestehen.

TLDR: I can’t get memory recognized on slots A1 and A2 of the motherboard and I don’t know how to tell if I have a bad mobo or a bad IMC on the CPU. Initially all slots reported RAM but system wasn’t stable until it threw a Memory PMU training error after I went from default 2133MHz to 3000MHz (XMP 1) then back to default again.

I have tried multiple sticks of RAM in these slots. All other slots work (and all RAM works in other slots), but with configurations of 2 to 8 DIMMs (all the same RAM from the same batch) A1 and A2 give me «Memory PMU Training error at Socket 0 Channel 2 DIMM 0 & DIMM 1» (when both are occupied) or «Memory PMU Training error at Socket 0 Channel 2 DIMM 1» (when only using slots A2 and B2 per the Memory Configuration page of the motherboard manual for 2 sticks of RAM.

Initially I populated all 8 slots with RAM and benchmarked at 2133MHz. Then when trying to run a SfM benchmark (intended use of this machine) I got an unexpected reboot partway through. Tested the RAM overnight with WMD and came back to a frozen system in windows. Rebooted and event viewer said all the RAM was fine. Loaded XMP profile 1 (3000MHz) and benchmarked great with Passmark (99th percentile, 6778 total, 43468 CPU, 2908 Memory). Tried the SfM benchmark again and got an unexpected reboot partway through again. Reloaded defaults and BIOS finally threw the Memory PMU training error. The system was never stable at 2133MHz or 3000MHz until I got the error and A1 and A2 were disabled. Since they became disabled, I see Memory PMU training error any time a stick is in A1 or A2, and I have never seen any stick of RAM work in them again.

Since BIOS threw the PMU error I haven’t had any system freezes or reboots. I can populate all six other slots of the motherboard and run at 3000MHz (XMP profile 1) for days without an issue. Any time I put RAM in A1 or A2, XMP won’t stick, BIOS cycles several times, and memory drops to 2133MHz with PMU error (even if only 2 sticks — in A2 and B2). After giving up on this channel (channel 2 apparently?) I gradually filled RAM and tested at 2133MHz and 3000MHz for C2/D2, C1/D1, and finally B1&B2 and with all configurations I am successfully running at XMP profile 1.

Is it possible to test if it’s a bad mobo or IMC without swapping out another one of either (or both)?

[SOLVED] Unable to use RAM slots C1 et C2 on TRX40 Creator

Hello guys,

I recently purchased a ASRock TRX40 Creator motherboard and I’m facing a problem with only RAM slots C1 and C2.

The RAM I have is 2 pairs of Corsair Vengeance LPX 32Go (2x16Go) DDR4 3200MHz (CMK32GX4M2B3200C16).
I have the latest BIOS (P1.30) installed and the CPU is a Threadripper 3960x.

If I try to boot with only 1 stick on any on these both ports, the computer won’t start (black screen).

Then, if I try with 4 sticks in either A1,B1,C1,D1 or A2, B2, C2, D2:

I get the following error during the boot sequence: «Memory PMU Training error at Socket 0 Channel 4 DIMM 1«
only 3 of the stick appears in the bios (A, B and D)
CPU-Z indicates I’m in Triple Channel mode with a size of 48GB

I have tried all sticks on both of the C slots and get the exact same problem every time. Using any combination of 3 sticks also always works. I also tried to boot in dual channel with a spare pair of 8GB memory (CMK16GX4M2B3000C15). This tests make me think it is not due to a faulty memory.

I haven’t changed any BIOS setting (factory default). I also checked the CPU pins and they all look fine.

Could anybody help me on this? What should I do next?

Yes, I am. And Only A, B and D shows up on the main screen.

If you’re able to get into the BIOS when you tried the RAM in A2, B2, C2, D2 the manually set XMP and make sure the timings and voltage matches your RAM or enter those settings manually…even lowering the speed to 2933MHz.

Do you think I should return the extra pair I recently ordered and get a 4x8Go Corsair Vengeance LPX 3600MHz kit (CMK32GX4M4B3600C18) instead? Which is in the compatibility list.

If you cannot get them to work together, return both pairs and get either 2x 16GB kit or 4x 8GB kit

Which motherboard and CPU ?
When you mix RAM that was not tested to work together could cause that issue.
You might need to manually select XMP at lower speed…2933MHz to see if the two pairs can run at that speed.
You should have got a 4 stick kit, since RAM might look similar…but half the times the IC chips are different.

The motherboard is a ASRock TRX40 Creator and the CPU is a Ryzen Threadripper 3960x.

I already owned a pair, and I recently bought an extra one, for that config. But thanks for the advice, I’ll think about it next time.

Even when I try with only 2 sticks, I get the same issue. With one stick (on a slot C), the PC doesn’t even boot (while it does using A, B or D). Don’t you think this seem to indicate a faulty motherboard instead of a faulty RAM?

I will still try to use XMP and lower the frequency. That’s a good idea. Thanks again.

Check the CPU socket for bent pins.

Take a look at this. It’s important to check your manual for memory setup. This board does not accept 1 stick. You have to use 2 sticks on A2-B2. For 4 sticks its A2-B2, C2-D2.View: https://imgur.com/a/Yz0OKQj

I have the manual on my desk opened at that page And that’s what I tried first (A2, B2, C2, D2). I also tried to swap sticks around with no luck.

Memory manufacturers won’t guarantee such combinations of memory as you have to work together. Your free to play around and do your own compatibility testing.

As already posted, C1 and C2 are not valid Memory Configurations for using one or two DIMMs.

Are you able to get into the BIOS when you tried the RAM in A2, B2, C2, D2?

Yes, I am. And Only A, B and D shows up on the main screen.

Memory manufacturers won’t guarantee such combinations of memory as you have to work together. Your free to play around and do your own compatibility testing.

As already posted, C1 and C2 are not valid Memory Configurations for using one or two DIMMs.

Do you think I should return the extra pair I recently ordered and get a 4x8Go Corsair Vengeance LPX 3600MHz kit (CMK32GX4M4B3600C18) instead? Which is in the compatibility list.

If you cannot get them to work together, return both pairs and get either 2x 16GB kit or 4x 8GB kit

If you’re able to get into the BIOS when you tried the RAM in A2, B2, C2, D2 the manually set XMP and make sure the timings and voltage matches your RAM or enter those settings manually…even lowering the speed to 2933MHz.

So I tried that and same problem remains.. the memory stick on C2 never shows up. The default XMP timings are correct, and a lower frequency didn’t help.

Got it. I’ll think about that option.

Hi,
I have the same problem as you. But on slots A1 and A2. I get the memory training error.
I have tested 4 different memory brands. I discovered that problem always happens when the board is cold on the morning when you turn the PC on. But I believe it is a Bios problem. Looks like the cold boot procedure does not assign the correct memory voltage I think.

When you enter the BIOS, If you load default setup and set the XMP profile manually all works fine. Passes all burning tests on Windows and is stable, not a single issue. I had the problem with the original BiOS, then version 1.5 got the issue, but somehow it fixed by itself and worked fine for two months.
Then, about a week ago I upgraded to BiOS 1.6 and the problem started again. Tryed a lot of things but nothing happened. I reverted back to 1.5 and the problem did not got solved. But on experimenting, once I loaded the default values started to work again, so I reflashed version 1.6 with default values and worked fine the whole day. But now again on cold boot memory training errors. (Actually is not cold temp here on my home, about 20° C on morning).
So I went to BIOS and the values wasn’t the default ones that I loaded the day before. I again loaded the defaults, configured the XMP profile and that worked fine. This time I saved the profile on default 1 slot, booted, saved the values again. Booted again, saved the values again (all this to make sure that the config gets saved).
I will have to wait until tomorrow for a cold boot to check if the values are keept saved as it looks like there is some kind of long discharge capacitor that keeps a NVRAM fresh.
My recommendation. If you can return the board and get another from ASUS go that way. This Asrock board is just crap. I wasn’t able to get it exchanged on my local retailer because the board works fine when you test it on the same day and when I explained the issue they keept blaming to my memory sticks.
Those sticks where all working fine on my previous ASUS board with my first gen ThreadRipper so I blame Asrock for this.

You are totally right to blame ASRock. Since then, I returned the MB and ordered an Asus Prime TRX40 Pro instead. The problem went away.
