F5-6400J3239G16GX2-RS5K on MSI Z790 gaming pro wifi not working at XMP

[k3nt0n]

I've this memory: F5-6400J3239G16GX2-RS5K
This mobo: MSI Z790 gaming pro wifi (BIOS updated, CMOS cleared at every memory change, memory in A2-B2 slots like MSI manual)
This CPU: i5 13500

At 4800 (40 40 40 77) all ok
At 6400 32 39 39 102 XMP memtest86+ give 800+ errors and SO freeze at blu screen on boot

I did amazon change but the new pair give same errors

I buy other type: F5-6800J3445G16GX2-TZ5RK (6800 34 45 45 108)
but i've same behaviour, or even worst (the system reboot continuously after first time and don't reach neither the BIOS)

Only 4800 is a stable and working configuration by now. The XMP appear to work if i mount a bank alone. (16 GB single in A2 or B2 slot) (not tested a lot)

Someone can help me with the F5-6400J3239G16GX2-RS5K ?

Thanks you

Best regards

Did you try a lower DRAM Frequency with XMP enabled to see what can work? DDR5-6000? 5800? 5600?

It is possible the CPU is not capable of full DDR5-6400.

[k3nt0n]

Ok i'll try and i will tell you the results.
Seems clever...

But here -> https://it.msi.com/Motherboard/Z790-...FI/support#mem
you can see (13 gen non k tab) that those ones are supported:

F5-6800J3245G16GX2-TZ5RK 6800
F5-6400J3239G16GX2-TZ5S 6400
F5-6400U4040F16GX2-TZ5S 6400

and many others up to 6800 with my processor

no OC tweaks possible?

[GSKILL TECH]

First need to make sure hardware is normal. If DDR5-6000 or 6200 is stable, some OC tweaks may be helpful. If DDR5-5600 is unstable, OC tweaks will not help much.

You mentioned single bank A2 was much more stable; did you test both modules or only one?

[k3nt0n]

I tested 1 alone just for try some days ago.
All tests are refered to dual channel A2 B2.
So 5800 32 39 39 102 is stable.
Even 6000 but not tested enough.
At 6000 the temperature of the RAM modules start to increase but i think it's normal.
Tomorrow i will try 6200.
Thanks you for your support

I used 6200 32 39 39 102 (xmp with lower frequency 6400->6200) and everything is ok until now, stable.
Do you suggest to try 6400 with some tweaks or to let this parameters?
(And maybe when i will upgrade CPU i could try again 6400 or more)

[GSKILL TECH]

You can try inputting or increasing DRAM Voltage and/or CPU System Agent Voltage to see if it can improve stability for DDR5-6400. If not, use DDR5-6200 parameters and try with another CPU in the future.

I get it, tkx u a lot!

I would share my knowladge about twiking of the same RAM. It couldn't boot on 6400 XMP, but it works almost stable on 6200 with same timings. In result of twiking i found that tRCD timing cause the problems. Since i set tRCD to 43 i have no problem running 6400 mhz. Also, make sure you didn't set "Memory context restore" to enabled because it may cause problems

Hello Friends. I have a similar problem. I don't speak English, I apologize for the translation mistakes.

I bought "G.SKILL F5-5600 J3636 D32 GX2-RS5K - CL36-36-36-89 1.25V".

I assembled a new system with the following components.

MSI Z790P Wifi motherboard
i5-13600KF processor
Palit 3080 Ti video card
Performance 800 W Gold Psu
DeepL500 liquid cooler
Samsung 840 Evo 500 gb SSD
MLD M300 NVMeSSD 500 gb
W11 Pro

The system often freezes at the Windows logo when booting up. After several attempts, the system boots up. I have never experienced any problems after the system boots up. I have never experienced any problems in stress tests and programs such as "Photoshop", "Premier", "After Efect" that I use, such as stuttering, freezing, blue screen.

As I said, the problem is in system startup. When the BIOS load is finished and windows starts to load, the system freezes after 1-2 seconds at the "Windows" logo. After 5-6-10 attempts, if I am lucky, the system boots up. But the big problem is when formatting or updating. I press the reset button because the system won't boot. Sometimes I turn it off and on from the power button. After a few tries, I get a message that the files are damaged. I switch to automatic recovery. This vicious cycle of repeated reboots, freezes, etc. sometimes lasts for hours.

No OC. BIOS is at default settings. Tried 3 different video cards (AsusRTX2070-ZotacRTX3080Ti-PalitRTX3080), different hard disks, Windows10, removed unnecessary hardware, no heating problem. I updated the BIOS version. The RAMs passed a 6-hour test with a program called Memtest86. No problems found.

The RAM is not listed on MSI's motherboard compatibility list. But the G.Skill website says it is compatible with my motherboard. I had already taken this information into consideration when I bought the RAM.

What method and sequence should I follow to solve this problem.

I think the problem is the RAM, which is not listed in MSI's compatibility list. G.Skill's list does. However, should I install a compatible RAM approved by MSI?

As I said, I'm not having any problems after booting up. If I go for a replacement, what order should I follow, motherboard? CPU? RAM? What are your opinions? Thank you very, very much in advance.

Did you populate slots two and four away from the CPU? Have you tried one module at a time to see if one performs differently? Feel free to send them in for replacement to see if another kit can work better.

Thank you. Yes, I am using slots 2 and 4. I haven't tried the modules one by one. I will try and see. I hope I can exchange with a different module in my country. Do you have a branch in Turkey that does this? Thanks again

[GSKILL TECH]

No, Nederlands may be the nearest

[foxfo]

Thank you. A company in my country provides service. It's contracted with G.Skill. I sent it there. I'm waiting for the result. I'll inform you when it's clear.

Hello, guys. One of the rams was defective. They sent a new one.

Thanks to GSKILL TECH . He reminded me to send it for replacement. The authorized company in my country also determined that it was defective without any difficulty and sent a new one.

Thanks again.
