Question Motherboard keeps showing code A6?

[Zphere]

Hi everyone,

I recently built a new computer and have been running into an intermittent issue related to my RAM (I think).

After I got windows installed and got everything updated (BIOS, chipset, etc.) I restarted my system and configured EXPO. I enabled it and left the profile to auto, which had the RAM at 1.35v and at 6000mzh.

My computer does code 15 (which I think is memory training/testing) and then throws code A6. I cleared CMOS, then tried lowering the speed to 5800mzh and it worked until I turned my computer off and tried to turn it on the next day.

I then set my speeds after clearing CMOS to 5600mzh and the same thing occurred. I can reboot and the computer works fine but if I shut down and turn it on again the next day, I get code A6 after the mobo runs through code 15.

I can access bios and get the system to boot after clearing CMOS. This sets my RAM speed to 4800 with EXPO disabled.

Is my assumption correct that this is a RAM related issue? If so, how do I go about resolving it and preventing it from happening? Ideally I want to run my RAM at 6000mzh if possible.

Thank you for any responses and let me know if any more info/clarification is needed.

Specs:
MSI MPG X670E
RYZEN 9 7950X3D
G.SKLIZ 32GB DDR5 RAM with EXPO
BIOS VERSION: E7D70AMS.180 (7D70v18)

Some extra info… I tried to run memtest86 and my computer just turned off during the test lol. No error code either, just powered off. This was with EXPO enabled with ram at 6000mzh.

Gonna try running it with EXPO off.

What PSU is installed: make, model, wattage, age, condition (original to build, new, refurbished, used)?

Doublecheck the motherboard's supported RAM configurations. Some motherboards require that the first physically installed RAM be placed in a specific slot.

This motherboard?

https://download.msi.com/archive/mnu_exe/mb/MPGX670ECARBONWIFI.pdf

DIMMA2 is to be the first slotted RAM position. Reference physically numbered Page 29.

[Do verify that I found the correct motherboard User Guide.

What is the overall RAM configuration 2 x 16 GB, 4 x 8 GB?

= = = =

That said, going back a bit......

What is the driving requirement for 6000 mzh?

Very unlikely that there will be any difference in overall performance between the cited lower speeds and 6000.

For the most part, my thought is that the system is not able to (for whatever reasons) fully support 6000.

And rolls the speed back. If the speed can be fixed and the system continually runs at 6000 then there may be longer term and more adverse after effects.

If this ram is more than one stick is it a kit?
If more than one stick test each stick by itself in the proper slot.

Hi Ralston, yes that is the correct motherboard!

Everything in this build is new except for the GPU. I’m using the same one for my old system.

I have 2 sticks of ram (2x16) and they are plugged into A2B2 on the motherboard as the manual suggests. If running the memory at 6000mzh won’t provide as much of a performance boost as I had hoped, I’d be happy with the system being stable at a lower speed.

The PSU is an SF1000L (1000w) from Corsair and was installed on Friday 9/29.

If more than one stick test each stick by itself in the proper slot.

Yes, I believe it’s a kit. I have 2x16 GB sticks. Should I test them both at a higher mzh or leave expo off?

A kit will come as 2 sticks in one package.

Test each stick with expo on and off see if either fails.

 

[Ralston18]

Determine if the system is stable without any overclocking etc..

And wait a few days to ensure that stability continues.

Windows or other software may be trying to do updates, backups, or even "phone home".

Changing more than one thing at a time will just make troubleshooting all the more difficult.

Forego further testing or other changes. Keep notes on problems and other things that happen.

Then begin to address the problems or desired/required changes one at time in a controlled methodical manner.

Thanks for the clarification. I will give this a go

Okay thank you, I will give it a few days before trying any other changes
