RAM or Motherboard Issue ?

[Armurowind]

Hello everyone,

I've just upgraded to a new motherboard, CPU, and DDR5 RAM, but I'm encountering issues with booting up when the RAM is installed in the A2 and B2 slots. After conducting some tests, it seems that the B2 slot may be

faulty, but I'd appreciate a second opinion.

Here are the details:

Motherboard: Asus ROG Strix x670e-F GAMING
RAM: G.Skill Trident Z5 RGB (2x16GB) F5-6000J3038F16GX2-TZ5NR

The RAM kit appears to be on the compatibility list for this motherboard, and Memtest passed successfully. Here are the test results:

Boot : Go to Windows
No boot : Powered On but can't get to the BIOS (orange LED)
Reboot and no boot : After modification, boot then shutdown then boot again but can't get to the BIOS and orange LED

Thank you for any assistance!

Hello Armurowind

G.Skill's QVL shows your memory is compatible.

Have you updated the motherboard bios to version 2007? Updating the bios can help with memory compatibility and stability.

To ensure the bios update goes well, shut down your pc, turn off the psu switch and install one memory stick in the A2 slot. Press and hold the clear cmos button for 3 seconds.

You can use bios flashback or EZ-Flash to update the bios. If you have any questions or need help updating the bios, feel free to ask.

Hello,

I did try the CMOS with each ram in A2, PC boot normally.
If I try to put the other one on B2, it boot then shutdown then boot again but I can't get to the BIOS, just got that orange LED on the motherboard.
However, if I put the ram on A1 and A2, PC boot normally.

So could it be the B2 slot who's faulty ?

[Nate152]

From your testing, it also doesn't boot with the memory in the A2-B1 slots, so it's hard to say. I'd still try updating the bios to see if this helps.

If updating the bios doesn't help, the issue with the B1and B2 slots not working can be caused by an overtightened cpu waterblock or bent cpu socket pins.

You could try loosening the mounting screws of your cpu waterblock a little and see if this gets slots B1 and B2 working.

If that doesn't help, remove the cpu waterblock and cpu, inspect the cpu socket for any bent or misaligned socket pins, look closely with a magnifying glass. You can post us a picture of the cpu socket for us to inspect if you like.

So, I did remove the CPU, didn't saw any bent socket pins :

I've put the CPU back, try with 1 stick in A2 -> Ok 
2 sticks A2 and B2 -> same problem as before

Hello, @Armurowind 

Thank you for reaching out to us and sharing the details of the problem.
According to the ROG STRIX X670E-F GAMING WIFI user manual recommendations, two memory modules should be installed in the DIMM_A2 and B2 slots.
However, based on the information you provided, there have been issues with booting or post-overclocking boot failures in most BIOS versions using the A2 and B2 slots.

May I ask if clearing CMOS under BIOS 2007 and enabling EXPO I, which optimizes memory timings and parameters by ASUS, would post-overclocking boot failures still persist?

 If so, could you please provide the following information to further investigate?
- the current BIOS version and the images of all the manually adjusting items in BIOS
- the brand and model name of the CPU, GPU, SSD/HDD, and PSU currently installed
- the OS version and OS build
- a comprehensive video recording of the issue, including the ability to boot into the 2007 default BIOS with RAM installed in the A2 and B2 slots, but after setting EXPO I and saving, the inability to boot and the Q-LED RAM indicator lights on.

Thank you.
