Question What is the configuration error. The computer freezes

[JoHN050375]

MB: B550 Aorus Pro AC
CPU: AMD Ryzen 9 5900X
GPU1: Quadro K4200
GPU2: GeForce GT 1030
MEM: DDR4 128 GB

Good morning, Can you help me diagnose the problem. The computer freezes.
Thank you for all the tips and hints. If necessary, tell me what tests to include to start with something.



Yours faithfully

My guess: this is memory related. Are you overclocking anything? Anyway, I would start with Memtest86. You have a lot of memory, and there is a possibility some of it is bad/unstable, or the memory is putting to much stress on the memory controller, causing instability. You could also see if there is a BIOS update for your motherboard which may help.

 

[igor_kavinski]

Yeah, like Shmee said, check for BIOS update. If there is one, update to it. Then check if the RAM modules you are using are on the mobo's QVL list. After that, take out three DIMMs and just work for a while with one DIMM. If no issue, take it out and check with 2nd one and so on. If all DIMMs are fine on their own, start using two of them together and repeat the whole process. Then install three of them. If they all work fine and only filling all the slots is causing an issue, maybe you need to increase the voltage on your IMC so it can handle the stress of four DIMMs better.

Domyślam się: jest to związane z pamięcią. Przetaktowujesz coś? W każdym razie zaczynałbym od Memtest86. Masz dużo pamięci i istnieje możliwość, że część z nich jest zła/niestabilna lub obciążająca kontroler pamięci, co niestabilność. Możesz także sprawdzić, czy dostępna jest aktualizacja systemu BIOS dla Twojej płyty głównej, co może pomóc.

The PC is not overclocked.
I updated the BIOS to the latest version.
The memory is not in the mobo's QVL.
I noticed that the memory works at a lower frequency than set in the BIOS.
Executing mdsched showed no error.

What steps to take next?

 

[Shmee]

Run some other tests, such as Memtest86, OCCT memtest, prime95 etc to see if there is still instability. Windows memory test won't catch everything.

 

[DAPUNISHER]

They gave you good advice. As advised, flash to F16c, that's the latest bios for your board.

It's always good to provide the power supply make and model too.

I'd pull that 1030 until you get things stable. It's possible it isn't playing well with the 462.96 drivers. It's probably fine, but it's one less thing.

If it still isn't stable, I'd also pull 2 sticks of ram, as they suggested. Or you could start by increasing voltage.

Significantly reduced performance.

I did the tests. It turned out that the memory chips were from two different production periods. After replacing the memory banks, I ran Memtest86 and OCCT memtest. Now the system indicates that it is stable.

However, I have noticed a significant drop in performance. Memory modules are DDR4 Patriot Viper Steel 64GB(2x32GB) 3600MHz CL18. In CPU-Z or in OCCT memtest you can see that the chips work at a very low frequency.

What could be the reasons for this, since the manufacturer gives a frequency of 3600MHz and from CPU-Z or OCCT programs it is only 1333MHz?

 

[igor_kavinski]

DDR4-3600 is the overclocked speed.

Go into BIOS and set that speed manually.

In your BIOS, set the following speed and timings:


1802 means you will set DDR4 to 3604 MHz.

Then find the CAS, RCD, RP etc. in the manual RAM tuning section of your BIOS and set them to the values shown. Reboot and test for stability. That should do it.

I updated the BIOS to the latest version following the tip of DAPUNIZER.
I changed the RAM frequency to 1800 MHz in the BIOS.
I can't enable the BIOS to change the CAS, RCD, RP, RAS, RC, FAW, RRDS, RRDL values. Where in the BIOS do I have to click to be able to influence these values?

 

[igor_kavinski]

Where in the BIOS do I have to click to be able to influence these values?

Is the system not booting setting the RAM to 1800 MHz? What is the minimum and maximum speed for the RAM there?

I have no idea about ASUS BIOS, unfortunately.

Here's a guide but not sure if it will help you: https://www.teamgroupinc.com/en/info/ins.php?index_id=80

Thank you for all the tips and hints. Thank you for Link. It is certainly useful but in the case of the Aorus B550 Pro there is a problem.

Managed to overclock the memory to 1796.4 MHz, I also see that despite setting the parameters in the BIOS in accordance with the assumptions below, after using the CPU-Z utility, the values show different than those set.

The values that need to be set were given by igor_kavinski: CAS=18, RCD=20, RP=20, RAS=40, RC=72, FAW=38, RRDS=5, RRDL=4.
It would not be difficult to set all the values, but only some are selectable in the BIOS.
However, a number of questions arise, because some of the values given in the table shown by Igor_kavinski cannot be selected, so it seems that I lack the knowledge of what to do next. Should I assume that these notations balance out?:
I don't have the option to select the 1802 MHz memory timing. Only 1800 MHz is available.

a. CAS = ? (can't find in BIOS)
b. RCD(20) =? Trcdrd = 20h (it is not possible to select only the digit 20, only the value 20h is available)
c. RP(20) =? Trp = 20h (it is not possible to choose only the digit 20, only the value 20h is available)
d. RAS(40) = ? Tras = 3Ah (not in the selection under the option)
e. RC(72) =? TRC Ctrl = 72 (set)
f. FAW(38) =? Tfaw Ctrl = 38 (range 36h-6h to choose from, after selecting manual the value 1a appears)
g. RRDS(5) =? TrrdS = 5 Clk (set)
h. RRDL(4) =? TrrdL = 4 Clk (set)

Could someone please take a look and tell me what I'm doing wrong?

 

[igor_kavinski]

Look at bottom of screen. It tells you what the setting is for. Tcl is CAS.

Personally, I think the BIOS is too complicated. Your CPU-Z timings seem fine. Tweaking them more might give you little extra performance but it is more likely that experimenting with those cryptic BIOS options may cause some serious issue. I say leave it. The timings are good for four sticks of RAM.

 

[Shmee]

Most of the timings can be left on auto. Unless you really want to tweak, test and repeat. Just be sure to stress test and memtest for stability.

The direction he indicated igor_kavinski seems to be the best at the moment. Can you advise how to overclock the processor? I also don't know whether to move the thread to the CPU group or can you continue here?

Better to create a new thread in the CPU section.
